The effects of various concentrations of honey and sucrose on the longevity and fecundity of Apanteles metesae (Nixon), an endoparasitoid of oil palm bagworm, Metisa plana (Walker) (Lepidoptera: Psychidae) were studied in the laboratory. Our results showed that there were a significant difference (p<0.05) in the longevity of A. metesae fed on various concentrations of honey solutions. Longevity of A. metesae was significantly longer when fed on 50% honey than on pure honey. Nonetheless, longevity of A. metesae females when fed on 50% honey was relatively longer than other honey concentrations. The parasitoid lived significantly longer when fed on 20% sucrose than fed on 50% sucrose and distilled water. However, the parasitoid fed on 50% honey had a longevity that was statistically similar to 20% sucrose and 50% sucrose. Fecundity of A. metesae differed significantly (p<0.05) when fed on 50% honey, 20% sucrose and 50% sucrose. The highest and lowest fecundity was when the parasitoids fed on 20% sucrose and distilled water, respectively. Overall, the result showed that 20% sucrose was a more suitable diet for A. metesae females as compared with other diets.
