Abstract

Laboratory tests were carried out to determine the effect of various larval stages of oil palm bagworm, Metisa plana Walker (Lepidoptera: Psychidae) on development and oviposition behaviour of Apanteles metesae Nixon (Hymenoptera: Braconidae). The stages of M. plana larvae used were the 2nd, 3rd, 4th, 5th, 6th and 7th instars. Result showed that the different of host larval stages significantly (P < 0.05) affected the number of larvae parasitized by the adult A. metesae and the percentage of A. metesae adult emergence. The developmental times of A. metesae from eggs till adult emergence was significantly (P < 0.05) different among host larval stages. However, there was no significant (P > 0.05) difference in a developmental time of parasitoid amongst the 3rd, 4th, 5th and 6th host’s instars larvae. A. metesae female did not oviposit on the 2nd and 7th larval instar of M. plana. The host larval stages significantly (P < 0.05) affect the oviposition behavior of A. metesae female on M. plana larvae. It was noted that the parasitoid female was thelytokous. This is the first record for species A. metesae in genus Apanteles that the reproduction is without mating and all offsprings are females
