中文摘要： 本文研究了光周期、温度和食料对大猿叶虫Colaphellus bowringi Baly哈尔滨种群滞育诱导的影响。结果表明，在恒温20~30℃范围内，大猿叶虫哈尔滨种群滞育率为91.8%~100%，未见明显的光周期诱导反应，但温度对其滞育诱导具有一定的作用，高温可使少部分大猿叶虫继续发育而不滞育。在平均25℃的温周期与光周期L12∶D12条件下，其滞育诱导差异不显著。大猿叶虫取食白菜、油菜、雪里蕻、萝卜和独荇菜5种食料，在25℃滞育率为89.5%~100%；在28℃滞育率为76.9%~100%，食料种类对大猿叶虫哈尔滨种群滞育诱导差异显著，其中，取食独荇菜滞育率最低，取食萝卜滞育率最高。
英文摘要： The effect of photoperiod, temperature and food on diapause induction in a Harbin population of Colaphellus bowringi Baly was investigated. There was no photoperiodic response, and at a constant temperature of 20-30℃ the diapause rate was 91.8%-100% at various photoperiods. Temperature had some influence on diapause induction; lower temperatures could promote diapause, but higher temperatures inhibited diapause in a few individuals. A thermoperiod of C12∶T12 combined with a photoperiod of L12∶D12 had no effect on diapause at a mean temperature of 25℃. The percentage of diapausing individuals was 89.5%-100% at 25℃ and 76.9%-100% at 28℃. Host-plants had a significant effect on diapause; the highest diapause rate was observed in individuals fed leaves of Raphanus sativus and the lowest in those fed leaves of Lepidum sativum.
