摘　　要：［目的］ 探求食料对大猿叶虫不同地理种群滞育的影响。［方法］ 在室内一定的温湿度条件下，观察比较大猿叶虫哈尔滨种群、泰安种群和龙南种群取食白菜、油菜、雪里蕻、萝卜和独行菜5种不同食料的滞育反应。［结果］ 食料对哈尔滨种群的滞育诱导作用不依赖于光周期，而对泰安种群和龙南种群的滞育诱导作用依赖于光周期。取食白菜、油菜、雪里蕻、萝卜和独行菜5种食料，大猿叶虫哈尔滨种群在25 ℃的滞育率为89.5%～100%，在28 ℃的滞育率为76.9%～100%；泰安种群在25 ℃的滞育率为21.7%～100%，在28 ℃的滞育率为4.5%～90.1%；龙南种群在25 ℃的滞育率为2.5%～100%，在28 ℃的滞育率为1.1%～90.9%。哈尔滨种群和泰安种群在25 ℃和28 ℃取食独行菜滞育率较低；龙南种群在25 ℃取食萝卜滞育率较低；在28 ℃取食白菜滞育率较低。［结论］ 食料对不同地理种群的大猿叶虫滞育诱导的影响显著。[Objective] The effects of food on diapause induction in different geographic populations of Colaphellus bowringii Baly was investigated. [Method] The diapause reaction of Harbin, Tai’an and Longnan populations of C. bowringii, fed with Brassica pekinensis, B. napus, B. jincea, Raphanus sativus and Lepidum sativum, were observed at constant temperature and humidity in the laboratory. [Result] The diapause induction of food in Harbin population was not related to photoperiod, but Tai’an and Longnan populations were significantly related to photoperiod. Fed with B. pekinensis, B. napus, B. jincea, R. sativus and L. sativum, the percentage of diapaused individuals was 89.5%-100% at 25 ℃ and 76.9%-100% at 28 ℃ in Harbin population, but the diapause rate was 21.7%-100% at 25 ℃ and 4.5%-90.1% at 28 ℃ in Tai’an population, and 2.5%-100% at 25 ℃ and 1.1%-90.9% at 28 ℃ in Longnan population. When fed with the leaves of L. sativum, the percentage of diapaused individuals was lower in Harbin and Tai’an populations at 25 ℃ and 28 ℃. However, the diapause rate was lower at 25 ℃ when fed with the leaves of R. sativus and was lower at 28 ℃ when fed with the leaves of B. pekinensis in Longnan population. [Conclusion] Different foods had different effects on diapause induction in the three populations.
