摘要 苜蓿切叶蜂Megachilerotundata(F.)预蛹的滞育主要受光周期和温度的影响。雌蜂感受光周期的变化是决定子代预蛹是否进入滞育的一个主要因素;当代的幼期,特别是高龄幼虫(约3龄)到预蛹这一阶段所感受的温度变化,对预蛹滞育有很大的影响,此期如果环境温度低于(2159±103)℃,可有超过50%的个体进入滞育。此外,放蜂地区的纬度及蜂的代次对预蛹的滞育亦有重要的影响。 Diapause of prepupae of the alfalfa leafcutter bee, Megachile rotundata (F.) is mainly controlled by both photoperiod and temperature. A main factor for female is the photoperiodical variation that decides whether progeny prepupae will enter diapause or not. For immature stages, especially from late instar (about third instar) to prepupae, temperature variation has a greater effect on prepupa diapause. During this stage, if the temperature is below (21 09±1 03)℃, more than 50 percent prepupae will enter diapause. In addition, the latitude of the area bees being released in and the generation of the bee also have an important influence on prepupae's diapause.
