EMBRYOLOGY OF PIMPLA TURIONELLAE (L.) (HYMENOPTERA: ICHNEUMONIDAE)

Abstract

The embryogenesis of the parasitic ichneumonid Pimpla turionellae (L.) is more similar to that of the aculeate A pis mellifera L. and the chalcidoid Eurytoma aciculata Ratz, than to that of other Hymenoptera that have been studied, including the ichneumonid Banchus femoralis (Thoms.). The fact that P. turionellae is a parasitoid has had little influence on its embryogenesis, though in some other parasitic insects embryonic development has been simplified and the embryo hatches before histogenesis of its larval tissues is completed.
