Abstract

Ovi t rap survei l lance was conducted in two urban res ident ial areas (Taman
Samudera Timur and Taman Samudera Selatan) and in a settlement area (Kampung Banjar),
which is located 16 km from Kuala Lumpur city center, Malaysia. In Taman Samudera, dengue
cases were reported monthly in 2003/2004. Thus, a study was initiated to determine the
distribution and abundance of dengue vectors, Aedes aegypti and Ae. albopictus. The ovitrap
surveillance indicated that Ae. aegypti and Ae. albopictus were present both indoors and
outdoors. The residential sites had 73 – 79 % of the ovitraps with just Ae. aegypti population
and Kg. Banjar had 56 % of the ovitraps with just Ae. aegypti. In the indoor and outdoor of
t h e r e s i d e n t i a l a r e a s , t o g e t h e r wi t h t h e s e t t l eme n t a r e a , t h e A e . a e g y p t i d e n s i t y wa s significantly more than Ae. albopictus (p < 0.05) by 3 – 50 folds. There was no significant difference in the larval numbers of Ae. aegypti between indoors and outdoors (p > 0.05), thus
implicating that adult gravid female Ae. aegypti are present both indoors and outdoors and
they do oviposit indoors and outdoors. Ae. aegypti can be incriminated as the principal dengue
vector in the urban residential site, Taman Samudera and in the settlement area, Kg. Banjar.
