Hymenoptera larvae were found in the nymphs of Eurygaster integriceps Put. in Saratov region and Armenia. These larvae underwent normal development at fiгst but then perished at the passage of their host to the adult stage. Similaг larvae occurred in some otheг Pentatomidae (Aelia, Eurydema, Dolycoris). Аn analysis of the external morphology, аnd of published data on endoparasites of Heteroptera allows to referthem with great probability to Braconids of the subfamily Euphorinae. The death of the parasites seems to bе due to the inability of their serosa cells to transform within the Е. integriceps body to giant cells that serve as the main food of the Euphorinae larvae. The populalion of the parasites studied mау Ье maintaiпed at the expense of their successful development in otheг hosts, рrоbablу, the species belonging to the family Miridae.
Личинки перепончатокрылых паразитоидов были обнаружены в нимфах и взрослых особях клопа – вредной черепашки Eurygaster integriceps Put. из Армении и Саратовской области. Зарегистрировано, что при переходе черепашки из нифмы во взрослое состояние личинки паразитоидов погибают. В ходе изучения внешнего строения и литературных источников было отмечено значительное сходство личинок перепончатокрылых с представителями подсемейства Euphorinae (Braconidae). Предположительно, личинка паразитоида не переходит во II возраст из-за утраты необходимого пищевого материала, а именно по причине дегенерации клеток серозы, выполняющих трофическую функцию в течение эмбрионального развития паразитов и продолжающих играть эту же роль после вылупления личинок из яйца.
