Abstract
Egg development in adult insects is characterized by an ecdysone-induced synthesis of vitellogenins (yolk protein precursors) by the fat body and their secretion into the hemolymph and subsequent endocytosis by the ovary (Kunkle and Nordin, 1985). However, in some cyclorraphous dipterans yolk protein synthesis occurs primarily in the ovaries themselves (Brennan et al., 1981; Rina and Mintzas, 1987; Handler and Shirk, 1988). Significant levels of yolk protein synthesis undoubtedly occur in insects with a high biotic potential and fecundity, such as tephritid fruit flies. Given the extensive economic damage caused by fruit flies, our ability to suppress their egg development by capitalizing on the regulatory role of ecdysone in yolk protein synthesis could significantly reduce existing levels of infestation.
