保幼激素类似物甲氧普烯（methoprene）对控制大斑腹萤（Diatraea grandiosella）成虫羽化节律的昼夜节律系统有影响。并与光周期、性别、温度等因素进行了比较。节律与光暗周期的相位差及其方差随光周期的增加而增大。男性比女性更早出现。较高的温度诱导早期羽化，降低了方差。一个平行的相位提前观察到局部用甲氧普烯处理的木瓜。在较高的剂量测试，烯虫酯诱导早期羽化。甲氧普烯的效果是剂量和年龄依赖性的，早期应用更有效。但在蛹期的前2天施用，3.0 μg的剂量是致死的。合成保幼激素I的效果不如甲氧普烯。甲氧普烯促进两性成虫的分化和羽化。
A juvenile hormone analogue (methoprene) affected the circadian system controlling the adult eclosion rhythm inDiatraea grandiosella. The effect of methroprene was compared with those of photoperiod, sex and temperature. The phase difference (ψ̃rl) between the rhythm and the light-dark cycle and its variance increased as the photoperiod increased. Males emerged earlier than females. Higher temperatures induced earlier eclosion and reduced the variance. A parallel phase advance was observed in papae treated topically with methoprene. At the higher dose tested, methoprene induced earlier eclosion. The effect of methoprene was both dose and age dependent, with earlier application more effective. A dosage of 3.0 μg was lethal, however, if applied in the first 2 days of pupal stage. Synthetic juvenile hormone I had less effect than methoprene. Methoprene accelerated adult differentiation and emergence in both sexes.
