Abstract
I examined the effects of host age at oviposition, from 0 to 4 days (egg to mature larva), on emergence rate and developmental period of the leafminer parasitoid Gronotoma micromorpha (Perkins) (Hymenoptera: Eucoilidae) under laboratory conditions in the host Liriomyza trifolii (Burgess) (Diptera: A gromyzidae). No significant difference was found in the emergence rates of G. micromorpha among the host ages examined. However, the developmental per iod pha was significantly shorter when ovipositing into 3- or 4-d-old L. tr ifolii. The occurrence of thelyotokous parthenogenesis in G. micromorpha wa s confirmed. The results show that G. micromorpha is an egg-pupal and larva l-pupal parasitoid, utilizing a wide range of host stages in which oviposit ion can occur and progeny can complete development.
