果蝇的幼虫，黑腹果蝇（Meigen），暴露于两个亚致死剂量的昆虫生长调节剂烯虫酯。测定羽化成虫的寿命和生育力。甲氧普烯治疗的女性开始卵黄卵母细胞发育更快，但在5天内比未处理的女性产蛋少。然而，产卵的生育力是不变的烯虫酯处理。与未治疗的男性相比，接受甲氧普仑治疗的男性不育的比例更高，主要（但不完全）是由于外生殖器旋转不完全。给药组雌性的成年寿命短于对照组雌性。结果表明，亚致死剂量的甲氧普烯可以显着影响双翅目昆虫的健身，必须考虑到这种杀虫剂的抗性进化的潜力估计时。
Larvae of the fruit fly,Drosophila melanogaster(Meigen), were exposed to either of two sublethal doses of the insect growth regulator methoprene. The longevity and fertility of adults that eclosed were determined. Methoprene-treated females initiated vitellogenic oocyte development sooner but laid fewer eggs over a 5-d period than untreated females. However, the fertility of oviposited eggs was unchanged by methoprene treatment. A higher percentage of methoprene-treated males compared with untreated were infertile, due largely (but not entirely) to incomplete rotation of the external genitalia. Adult life spans of treated females were shorter than those of control females. Results indicate that sublethal doses of methoprene can significantly affect the fitness of a dipteran insect and must be considered when estimating the potential for evolution of resistance to this insecticide.
