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.
