摘要: In a wild-type strain of Drosophila melanogaster Meigen, the antijuvenoid precocene I reduced primary sexual receptivity in dose-dependent manner; exposure to 0.80 μmol halved mating by virgin females 1-h test. Precocene-treated rejected courting males for longer times than control females, but rates rejection signaling per unit time were unaffected. Precocene slowed ovarian growth and markedly oviposition; 0.14 decreased oviposition about half. Protein deprivation severely volume lowered 3-d-old flies. Protein-starved decamped from more yeast-fed did at all ages tested, whereas both age diet affected stereotyped signals. II not affect receptivity, 70–140 ethoxyprecocene significantly.
