FEATURES OF THE STRUCTURE OF HYMENOPTERA ASSOCIATED WITH MINIATURIZATION. 2. ANATOMY OF TRICHOGRAMMA EVANESCENS (HYMENOPTERA, TRICHOGRAMMATIDAE)

摘要

Anatomy of adults of Trichogramma evanescens-(Hymenoptera: Trichogrammatidae) is described in detail for the first time based on a series of sections and the use of three-dimensional computer modeling. A strong simplification of the exoskeleton and musculature (except for reductions of individual muscles) is not observed in T. evanescens despite its tiny size. There is a simplification of the structure of the intestine, tracheal and circulatory systems, reducing the number of malpighian tubules. Thus, the smallest Hymenoptera (Mymaridae Trichogrammatidae) demonstrate the effects of miniaturization (reduction of head endoskeleton, circulatory and respiratory systems), both universal for insects and specific ones.
