Y. Abe, Egg-pupal and larval-pupal parasitism in the parasitoid Gronotoma micromorpha (Hymenoptera : Eucoilidae), APPL ENT ZO, 36(4), 2001, pp. 479-482
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.
