Meanings of Sexuality: Views from Malay Women with Sexual Dysfunction

Muhamad R, Horey D, Liamputtong P, Low WY, Sidi H

Arch Sex Behav, 2019 04;48(3):935-947.
PMID: 30066036 DOI: 10.1007/s10508-018-1228-1

In Malaysia, female sexual dysfunction (FSD) among Malays is common, so understanding the meanings of sexuality becomes crucial, as they can vary with identity, and this may influence each woman's subsequent reaction to sexual experience. In this article, we explore the meanings of sexuality that Malay women had developed throughout their lived experience. This qualitative study, situated within a social cognitive theory and a phenomenological framework, was conducted through in-depth and photograph elicitation interviews with 26 Malay women who had self-reported experiencing FSD. The findings suggest that the meanings of sexuality for these women linked closely with fundamental factors of Malay identity, which is comprised of tradition (Adat), religion (Islam), and language, that all influence gendered roles. Malay women understood sexuality to be sexual intimacy within marriage, privileging their marital role as a "good wife" over their personal rights within a sexual relationship. This understanding of sexuality was reinforced by meanings attributed to procreation, which Malay women linked closely to the purpose of marriage and their role as a "good mother." The findings should provide useful evidence that could be used in sexual health promotions to help reduce FSD and in clinical practice to generate appropriate therapy in Malaysia and elsewhere.

Managing Women with Sexual Dysfunction: Difficulties Experienced by Malaysian Family Physicians

Muhamad R, Horey D, Liamputtong P, Low WY

Arch Sex Behav, 2019 04;48(3):949-960.

Recognizing barriers to managing sexual issues makes it more likely that effective ways to overcome them will be found. In Malaysia, where discussion of sexual issues is taboo, sociocultural factors may influence how physicians manage patients with these types of problems. This article focuses on the challenges encountered by 21 Malay family physicians when women experiencing sexual problems and female sexual dysfunction (FSD) attended their clinics, an uncommon occurrence in Malaysia, despite their high prevalence. This qualitative study employed a phenomenological framework and conducted face-to-face in-depth interviews. Three main barriers to managing women with sexual problems were identified that can hinder assessment and treatment: insufficient knowledge and training; unfavorable clinic environments; and personal embarrassment. Some barriers were associated with physician characteristics but many were systemic. These were further evaluated using social cognitive theory. Professional attitudes appear important as those physicians with an interest in managing women's health seemed to make greater effort to explore issues further and work to gain trust. Physicians who appeared indifferent to the impact of FSD showed greater reluctance to find solutions. Systemic issues included unfavorable clinical settings, lack of training, and lack of local evidence. Any strategy to address FSD needs to be underpinned by appropriate policies and resources.

INTRODUCTION: Sexual activity is an essential human need and an important predictor of other aspects of human life. A literature review was conducted to investigate whether sexual abstinence in young and middle-aged men is generally considered a deliberate, healthy behavior and whether it has other causes and consequences.
AIM: To review the prevalence and factors associated with sexual abstinence in young (10-24 years) and middle-aged (25-59 years) men.
METHODS: Studies were retrieved from Science Direct, PubMed, and EBSCOhost published from 2008 to 2019. The selection criteria were original population- or community-based articles, published in the English language, on sexual abstinence, and in young and middle-aged men.
MAIN OUTCOME MEASURE: This article reviewed the literature on the proportions of and factors associated with sexual abstinence in young and middle-aged men.
RESULTS: A total of 13,154 studies were retrieved, from which data were extracted for 37 population- or community-based studies. The prevalence of sexual abstinence varied from 0% to 83.6% in men younger than 60 years. The prevalence of primary sexual abstinence was 3.4%-83.3% for young men and 12.5%-15.5% for middle-aged men. The prevalence of secondary abstinence for young men ranged from 1.3% to 83.6%, while for middle-aged men, it was from 1.2% to 67.7%. The prevalence of sexual abstinence decreased with increasing age in young men but increased with increasing age in middle-aged men. The significant factors reported were age, single status, poor relationships, low socioeconomic status, sex education, religious practices, caring and monitoring parents, and not using alcohol, cigarettes, or drugs. Although the variations in findings from different studies can be explained by different regions and cultures, the information cannot be generalized worldwide because of a lack of studies in Asian and Australian populations.
CLINICAL IMPLICATIONS: The studies on sexual abstinence in the future should use a consistent and standard definition, cover all sexual behaviors, and investigate all related factors.
STRENGTH & LIMITATIONS: The restricted timeframe (2008-2019), English language, availability of full text, and variability in definition and time duration may be the sources of bias.
CONCLUSION: Young men had higher proportions of sexual abstinence than middle-aged men, and age, unavailability of a partner, lower educational levels, low socioeconomic status, conservative and religious conditions, and no or less knowledge about sexually transmitted infections were common predictors of sexual abstinence in most of the men. Although determinants of sexual abstinence were identified, further investigation of biological factors in men younger than 60 years is needed. Irfan M, Hussain NHN, Noor NM, et al.

Fulltext Knowledge, attitude and practice towards sexually transmitted diseases amongst the inmates of women shelters homes at Klang Valley

Zin NM, Ishak I, Manoharan K

BMC Public Health, 2019 Jun 13;19(Suppl 4):639.
PMID: 31196029 DOI: 10.1186/s12889-019-6863-5

BACKGROUND: Previous studies show that there is a changing trend of sexual and reproductive behaviour among youth and this requires more attention and awareness especially on sexually transmitted diseases (STD). This study was carried out to evaluate the knowledge, attitude and practice of sexually transmitted diseases among selected inmates of women shelter homes.

METHODS: A cross-sectional study was carried out by involving 60 participants whom aged in between 13 to 25 years old. The questionnaires were developed in 'Bahasa Melayu' and it has been anonymous guided questionnaires.

RESULTS: The result showed that the mean age of the participants was 17.9 years old and most of the participants have completed secondary school (91.7%). Overall, the level of knowledge of participants on STDs were classified into three groups; 'high knowledge' (33.3%), 'medium knowledge' (35.0%) and 'low knowledge' (31.7%). The majority have heard of HIV/AIDS (95%) but with respect to other STDs was less well known. Whereas, the mean score for attitude was 23.1 out total 25. Their knowledge level was not influenced by their age (p = 0.61) and socio-economic status (p = 0.85). However, their attitude was influenced by their age (p sexuality contradicts it especially on contraceptive use and pre-marital sex.

Fulltext Penetration mechanics of elongated female and male genitalia of earwigs

Matsumura Y, Kamimura Y, Lee CY, Gorb SN, Rajabi H

Sci Rep, 2021 04 12;11(1):7920.
PMID: 33846369 DOI: 10.1038/s41598-021-86864-1

We unveiled the penile penetration mechanics of two earwig species, Echinosoma horridum, whose intromittent organ, termed virga, is extraordinarily long, and E. denticulatum, whose virga is conversely short. We characterised configuration, geometry, material and bending stiffness for both virga and spermatheca. The short virga of E. denticulatum has a material gradient with the stiffer base, whereas the long virga of E. horridum and the spermathecae of both species are homogeneously sclerotised. The long virga of E. horridum has a lower bending stiffness than the spermatheca. The virga of E. denticulatum is overall less flexible than the spermatheca. We compared our results to a previous study on the penetration mechanics of elongated beetle genitalia. Based on the comparison, we hypothesised that the lower stiffness of the male intromittent organ comparing to the corresponding female structure is a universal prerequisite for the penetration mechanics of the elongated intromittent organ in insects.

Fulltext Knowledge of sexually transmitted diseases and sexual behaviours among Malaysian male youths

Awang H, Wong LP, Jani R, Low WY

J Biosoc Sci, 2014 Mar;46(2):214-24.
PMID: 23480474 DOI: 10.1017/S0021932013000114

This study examines the knowledge of sexually transmitted diseases (STDs) among male youths in Malaysia. A self-administered survey was carried out on a sample of 952 never-married males aged 15-24 years. The respondents were asked about their knowledge of STDs, how these diseases get transmitted and their sexual behaviours. The data showed that 92% of the respondents knew of at least one STD (syphilis, gonorrhoea, chlamydia, herpes, genital warts, yeast infection, trichomoniasis or HIV/AIDS). About 95% of them knew of at least one method of STD transmission. Urban and tertiary-educated male youths showed a substantially higher proportion of awareness of STDs and transmission methods compared with their rural and less-educated counterparts. The data also indicated that 10% of the study sample admitted to having had sexual experiences. There were still a large proportion of the respondents who were not aware of STDs other than syphilis and HIV/AIDS and the means of transmission, such as multiple sex partners, including those who claimed to be sexually active. Thus there is a need for more concerted efforts to disseminate information on STDs and transmission methods to a wider audience in Malaysia, especially youths in rural areas.

Effect of Eurycoma longifolia Jack on orientation activities in middle-aged male rats

Ang HH, Lee KL

Fundam Clin Pharmacol, 2002 Dec;16(6):479-83.
PMID: 12685506 DOI: 10.1046/j.1472-8206.2002.00106.x

The effects of various fractions of Eurycoma longifolia Jack were studied on the orientation activities of the inbred, adult middle-aged Sprague-Dawley rats, 9 months old and retired breeders towards the receptive females (anogenital sniffing, licking, mounting), the environment (climbing, raring, exploration), themselves (nongenital grooming, genital grooming) and mobility (restricted, unrestricted) after treating these subjects twice daily for 10 days. Results showed that subjects treated with 800 mg/kg of E. longifolia Jack increased orientation activities towards the receptive females (anogenital sniffing, licking and mounting), increased genital grooming towards themselves and restricted movements to a particular area of the cage but decreased interest in the external environment (climbing, raring, exploration) as compared with the controls during the investigation period. In conclusion, this study gives further evidences that different fractions of E. longifolia Jack modified the orientation activities of the middle-aged male rats.

Effects of Eurycoma longifolia Jack on sexual qualities in middle aged male rats

Ang HH, Ngai TH, Tan TH

Phytomedicine, 2003;10(6-7):590-3.
PMID: 13678248 DOI: 10.1078/094471103322331881

The effects of Eurycoma longifolia Jack were studied on the sexual qualities of middle aged male rats after dosing them with 0.5 g/kg of various fractions of E. longifolia whilst the control group received 3 ml/kg of normal saline daily for 12 weeks. Results showed than E. longifolia Jack enhanced the sexual qualities of the middle aged male rats by decreasing their hesitation time as compared to controls with various fractions of E. longifolia Jack produced 865-916 (91-96), 860-914 (92-98), 850-904 (93-99), 854-890 (95-99), 844-880 (94-98), 840-875 (94-98), 830-870 (94-98), 825-860 (94-98), 820-850 (96-99), 800-840 (93-98), 750-795 (94-99) and 650-754 sec (82-95%) in contrast to controls which produced 950 (100), 934 (100), 910 (100), 900 (100), 895 (100), 890 (100), 885 (100), 880 (100), 855 (100), 860 (100), 800 (100) and 790 sec (100%) throughout the investigation period. Besides these, there was a transient increase in the % of the male rats responding to the right choice after chronic administration of 0.5 g/kg E. longifolia Jack, with more than 50% of the male rats scored right choice after 2 weeks post-treatment and the effect was more prominent at the dose of the observation period. However, there was no sexual enhancement of the middle aged male rats which consumed normal saline since only 45-55% of the male rats responded to right choice throughout the investigation period. Hence, this study shows that E. longifolia Jack enhanced the sexual qualities of the middle aged male rats, further supports the folkuse of E. longifolia Jack as an aphrodisiac.

Eurycoma longifolia Jack enhances sexual motivation in middle-aged male mice

Ang HH, Lee KL, Kiyoshi M

J Basic Clin Physiol Pharmacol, 2003;14(3):301-8.
PMID: 14964739 DOI: 10.1515/jbcpp.2003.14.3.301

Eurycoma longifolia Jack was investigated for sexual motivation activity in adult, middle-aged male mice and in retired breeders, using the modified open field and the modified runway choice methods. Each mouse received 500 mg/kg of one of 4 fractions of E. longifolia Jack, viz. chloroform, methanol, butanol, and water, whereas the mice in the control and yohimbine groups received 3 ml/kg of normal saline and 30 mg/kg of yohimbine daily respectively for 10 d. The results show a transient increase in the percentage of male mice responding to the right choice after chronic consumption of the fractions with 50 percent of the adult middle-aged male mice treated with E. longifolia Jack and yohimbine scoring the right choice after 8 and 5 days post-treatment respectively. In conclusion, this study has shown that E. longifolia Jack continues to enhance sexual motivation in adult, middle-aged male mice and in retired breeders.

Fulltext Eurycoma longifolia Jack enhances libido in sexually experienced male rats

Ang HH, Sim MK

Exp Anim, 1997 Oct;46(4):287-90.
PMID: 9353636 DOI: 10.1538/expanim.46.287

The effects of Eurycoma longifolia Jack were studied on the libido of sexually experienced male rats after dosing them with 200, 400 and 800 mg/kg body weight twice daily of different fractions of E. longifolia Jack for 10 days. Results showed that E. longifolia Jack produced a dose-dependent increase in mounting frequency of the treated animals with 400 mg/kg of chloroform, methanol, water and butanol fractions resulting in mounting frequencies of 5.3 +/- 1.2, 4.9 +/- 0.7, 4.8 +/- 0.7 and 5.2 +/- 0.1, and 800 mg/kg further increased them to 5.4 +/- 0.8, 5.4 +/- 0.8, 5.2 +/- 0.6 and 5.3 +/- 0.2 respectively but there were no erections, intromissions, ejaculations or seminal emissions during the 20-min observation period which allowed for the measurement of sexual arousal reflected by mounting frequency uninfluenced by other behavioural components. This study provides evidence that E. longifolia Jack is a potent stimulator of sexual arousal in sexually vigorous male rats in the absence of feedback from genital sensation.

Teenage births on the decline

Peng TN

Malays J Reprod Health, 1986 Dec;4(2):91-6.
PMID: 12314888

PIP: In Peninsular Malaysia, while the female population aged 15-19 years registered a growth of some 240,000 persons between 1966-1984, the number of births occurring to teenage mothers has decreased by 15,176 from 33,348 to 18,172 during the same period. In 1966, teenage births constituted some 10.8% of the total births but has declined to 4.7% by 1984. A breakdown of the 1984 data by detailed age groups shows that only 0.9% of the teenage births had actually occurred among those below 15 years of age. The declining trend in teenage births, particularly the higher order births among the very young mothers, augurs well for the improvement in family welfare. However, in order to safeguard the health and welfare of mothers and children, concerted efforts should continue to be undertaken to integrate population, family health and family life education into the school curriculum.

Bullying and truancy: Predictors to sexual practices among school-going adolescents in Malaysia - a cross-sectional study

Azmawati MN, Dalila R, Idris IB, Hod R

Med J Malaysia, 2017 10;72(5):298-305.
PMID: 29197886

INTRODUCTION: Adolescents' involvement in sexual practices are becoming a major public health concern in Malaysia. This study aims to determine the prevalence of sexual practices among Malaysian school-going adolescents and its predictive factors.
METHODS: A cross-sectional study was carried out from April 2012 till September 2012 among 16-year-old school adolescents from two different schools. They were selected through simple random sampling and these adolescents answered a self-administered questionnaire consisting of three sections i.e. socio-demography, risk-taking behaviours and family-adolescents relationship. Data were analysed using Pearson Chi-Square test while Simple Logistic Regression and Multiple Logistic Regression were applied to determine the predictive factors.
RESULTS: The prevalence of sexual practices among the adolescents was 30.1% in which they were either involved in pornography (26.8%), pre-sexual activities (8.5%) or premarital sex (2.9%). Six predictive factors associated with sexual practices among this age group were identified which were male (adjusted Odds Ratio (aOR) 2.7, 95% Confidence Interval (95%CI) 1.4 to 2.5), truancy (aOR 2.3, 95%CI 1.3 to 4.2), bully (aOR 3.5, 95%CI 1.7 to 7.3), hanging out (aOR 2.8, 95% 1.4 to 5.6), staying out late (aOR 3.2, 95%CI 1.5 to 6.8) and conflict with family (aOR 4.1, 95%CI 1.9 to 8.9).
DISCUSSION: Asian background differs from the western countries and findings of this study may suggest suitable intervention programmes that can prevent high-risk sexual practices among Asian school-going adolescents.

Reproductive success of two male morphs in a free-ranging population of Bornean orangutans

Tajima T, Malim TP, Inoue E

Primates, 2018 Mar;59(2):127-133.
PMID: 29387973 DOI: 10.1007/s10329-017-0648-1

The reproductive success of male primates is not always associated with dominance status. For example, even though male orangutans exhibit intra-sexual dimorphism and clear dominance relationships exist among males, previous studies have reported that both morphs are able to sire offspring. The present study aimed to compare the reproductive success of two male morphs, and to determine whether unflanged males sired offspring in a free-ranging population of Bornean orangutans, using 12 microsatellite loci to determine the paternity of eight infants. A single flanged male sired most of the offspring from parous females, and an unflanged male sired a firstborn. This is consistent with our observation that the dominant flanged male showed little interest in nulliparous females, whereas the unflanged males frequently mated with them. This suggests that the dominant flanged male monopolizes the fertilization of parous females and that unflanged males take advantage of any mating opportunities that arise in the absence of the flanged male, even though the conception probability of nulliparous females is relatively low.

Fulltext Determinants of sexual intercourse initiation among incarcerated adolescents: a mixed-method study

Nik Farid ND, Che' Rus S, Dahlui M, Al-Sadat N

Singapore Med J, 2013 Dec;54(12):695-701.
PMID: 24356756

INTRODUCTION: This study aimed to investigate the determinants of sexual intercourse initiation among incarcerated adolescents aged 12-19 years in Malaysia.

METHODS: This was a sequential mixed-method research project that was conducted in two phases. Quantitative and qualitative methods were used in the first and second phases, respectively. Data was collected via a survey using self-reported questionnaires from 1,082 adolescents, and from in-depth interviews and the written essays of 29 participants. The participants were recruited from 22 welfare institutions in peninsular Malaysia.

RESULTS: Among the study participants, 483 were male and 599 were female. Overall, 62.3% of the incarcerated adolescents had initiated sexual intercourse at least once. The mean age at first sexual intercourse for both genders was 14.0 years. Individual factors found to be associated with previous sexual intercourse were the female gender (odds ratio [OR] 1.75; 95% confidence interval [CI] 1.11-2.74), previous alcohol use (OR 1.80; 95% CI 1.10-2.94), previous illicit drug use (OR 1.85; 95% CI 1.07-3.22), permissive attitude toward premarital sex (OR 4.34; 95% CI 2.17-8.70), and sexual abuse during childhood (OR 5.41; 95% CI 3.52-8.32). Qualitative findings revealed that the reasons for initiation of sexual intercourse among these adolescents were partner influence, inability to control sex drive, family issues, and the perception of sex as an expression of love.

CONCLUSION: The determinants of sexual intercourse initiation among incarcerated Malaysian adolescents are comparable to those of developed countries. However, in Malaysia, sexual and reproductive health programmes for such adolescents should be tailored to address their specific needs.

Fulltext Navigating HIV prevention policy and Islam in Malaysia: contention, compatibility or reconciliation? Findings from in-depth interviews among key stakeholders

Barmania S, Aljunid SM

BMC Public Health, 2016 07 07;16:524.
PMID: 27387326 DOI: 10.1186/s12889-016-3247-y

BACKGROUND: Malaysia is a multicultural society, predominantly composed of a Muslim majority population, where Islam is influential. Malaysia has a concentrated HIV epidemic amongst high risk groups, such as, Intravenous Drug Users (IVDU), sex workers, transgender women and Men who have sex with Men (MSM). The objective of this study is to understand how Islam shapes HIV prevention strategies in Malaysia by interviewing the three key stakeholder groups identified as being influential, namely the Ministry of Health, Religious leaders and People living with HIV.
METHODS: Thirty-Five in depth semi structured interviews were undertaken with religious leaders, Ministry of Health and People living with HIV in the last half of 2013 using purposive sampling. Interviews adhered to a topic guide, were audiotaped, and transcribed verbatim and analyzed using a framework analysis.
RESULTS: Themes including the importance of Islam to health, stakeholder relationships and opinions on HIV prevention emerged. Islam was seen to play a pivotal role in shaping strategies relating to HIV prevention in Malaysia both directly and indirectly. Stakeholders often held different approaches to HIV prevention, which had to be sensitively considered, with some favouring promotion of Islamic principles, whilst others steering towards a more public health centred approach.
CONCLUSIONS: The study suggests that Islam indeed plays an important role in shaping health policies and strategies related to HIV prevention in Malaysia. Certainly, stakeholders do hold differing viewpoints, such as stances of what constitutes the right approach to HIV prevention. However there are also areas of broad consensus, such as the importance in Islamic tradition to prevent harm and disease, which can be crafted into existing and future HIV prevention strategies in Malaysia, as well as the wider Muslim world.

Fulltext Psychosocial determinants of adolescent romantic relationship in Malaysia: Social media use, pornography surfing, sexual and reproductive health knowledge, and depression

Mud Shukri MI, Baharom A

PLoS One, 2023;18(12):e0295933.
PMID: 38117759 DOI: 10.1371/journal.pone.0295933

It is socially natural that adolescents engage in romantic relationship. However, there are negative health implications when they are not properly monitored and guided. The engagement in unsafe sexual practices has been reported to cause various adverse health and social implications affecting Malaysian adolescents. To date, why adolescents engage in romantic relationship has remained understudied. Prior studies on adolescent romantic relationship mainly focused on the western context. Hence, the reported findings are deemed not applicable for the Malaysian population. There are insufficient data on the prevalence and determinants of adolescent romantic relationship within the Malaysian context. Thus, the current study aimed to identify the prevalence and determinants of romantic relationship among adolescents in Seremban, Negeri Sembilan, Malaysia. Adopting a cross-sectional research design, this study's self-administered questionnaire survey, which was conducted from 25 May 2021 to 5 June 2021 in residential areas that were part of the "Healthy Community Empowers the Nation" programme (KOSPEN), involved 396 adolescents who fulfilled the study's selection criteria. In terms of age, the respondents were of between 14 and 19 years old, with median age (IQR) of 19 (2). Adolescent romantic relationship in this study recorded prevalence of 24.1%, which was comparatively lower than that of the western countries. The results further revealed social media use (AOR: 2.162, 95% CI: 1.202-3.888, p = 0.01), pornography website surfing (AOR 2.748, 95% CI: 1.517-4.977, p = 0.001), poor SRH knowledge (AOR: 3.885, 95% CI: 2.144-7.040, p < 0.001), and depression (AOR: 2.830, 95% CI: 1.323-6.055, p = 0.007) as significant determinants of adolescent romantic relationship. Thus, this study demonstrated the significant role of social media use, pornography website surfing, SRH knowledge, and depression on adolescent romantic relationship. Further longitudinal studies to investigate the temporal relationships between depression and romantic relationship are recommended. The highly significant association between SRH knowledge and romantic relationship in this study suggests that strategies on improving the level of SRH knowledge among adolescents should be prioritised.

Fulltext The impact of mild cognitive impairment on sexual activity

Momtaz YA, Hamid TA, Ibrahim R

Am J Alzheimers Dis Other Demen, 2013 Dec;28(8):759-62.
PMID: 24085247 DOI: 10.1177/1533317513504612

OBJECTIVE: The aim of this study was to identify the unique impact of mild cognitive impairment (MCI) on sexual activity among older adults.
METHODS: Data for the study were drawn from a national survey entitled the "Determinants of Wellness among Older Malaysians: A Health Promotion Perspective" conducted in 2010.
RESULTS: According to the Mini-Mental State Examination education-adjusted cutoff points, 15.6% of the 1046 respondents were identified as having MCI. Older adults with MCI had a significantly lower level of sexual activity than the healthy cognitive group (chi-square = 50.20, P < .001, 32.5% vs 62.3%). The results of 3-step hierarchical logistic regression model revealed that MCI is significantly associated with decreased sexual activity in community-dwelling older adults, over and beyond demographic factors, and age-related medical conditions affecting sexual activity (odds ratio 0.33, P < .001, 95% confidence interval 0.23-0.49).
CONCLUSION: Findings from the present study support the significant role of cognitive functioning to perform sexual activity in later life.

Pharmacophagy of methyl eugenol by males enhances sexual selection of Bactrocera carambolae

Wee SL, Tan KH, Nishida R

J Chem Ecol, 2007 Jun;33(6):1272-82.
PMID: 17443401 DOI: 10.1007/s10886-007-9295-0

After pharmacophagy of methyl eugenol (ME), males of Bactrocera carambolae (Diptera: Tephritidae) produced (E)-coniferyl alcohol (CF) along with its endogenously synthesized pheromonal compounds. CF was shown to be released into the air by the ME-fed males only during the courtship period at dusk and attracted significantly more males and females than the ME-deprived males in wind tunnel assays. However, earlier onset of sexual attraction and a higher mating success were observed only in the wind tunnel and field cage assays on the third day posttreatment of ME. Field cage observations on the male-to-male interaction indicated that the ME-deprived males did not exhibit aggregation behavior, but that ME feeding promoted aggregation behavior in B. carambolae. Field cage observations revealed that the ME-deprived males were not only attracted to the ME-fed males, but also appeared to feed on their anal secretions. The secretions were subsequently confirmed to contain CF along with endogenously produced pheromonal compounds. Results obtained for B. carambolae were compared to those previously obtained from its sibling species, Bactrocera dorsalis, and are discussed in light of species advancement in fruit fly-plant relationships.

Bactrocera carambolae and B. papayae are major fruit fly pests and sympatric sibling species of the B. dorsalis complex. They possess distinct differences in male pheromonal components. In the 1990's, wild Bactrocera fruit flies with morphological traits intermediate between those of B. carambolae and B. papayae were often captured in traps baited with methyl eugenol (ME). Chemical analyses of rectal glands of ME-fed males revealed that the laboratory Fl, F2, and backcross hybrids possessed ME-derived sex pheromonal components ranging from that typical of B. papayae to that of B. carambolae without any specific trend, which included a combination of pheromonal components from both parental species within an individual hybrid. ME-fed hybrids without any ME-derived pheromonal components were also detected. Further chemical analysis of rectal glands from wild Bactrocera males, after ME feeding in the laboratory, showed a combination of pheromonal components similar to that found in the ME-fed, laboratory-bred hybrids. These findings present circumstantial evidence for the occurrence of a natural hybrid of the two Bactrocera species.
