Abstract
Ecdysones are hormones that regulate molting and metamorphosis in insects and are secreted by the living prothoracic gland (Karlson 1963). Diapause is associated with a deficiency of ecdysone, and by the administration of ecdysone, is terminated immediately by resumption of normal development. Such is the case in such diverse forms as the pupal diapause in a blow fly, Sarcophaga argyrostoma (Robineau-Desvoidy) (Fraenkel and Hsiao 1968), and the larval diapause in the winter tick, Dermacentor albipictus (Packard) (Wright 1969). In studies evaluating ecdysones as plant protectants, certain steroids, when ingested, disrupted normal growth and development in several insect species (Robbins et al. 1968). Kaplanis et al. (1970) subsequently further demonstrated inhibitory effects on reproduction in the house fly, Musca domestica (L.). The present paper reports the effects of ecdysones and ecdysone-analogues on fecundity in the haematophagous stable fly, Stomoxys calcitrans (L.).
