光周期和温度对大猿叶虫龙南种群滞育诱导的影响
The Effects of Photoperiod and Temperature on Diapause Induction in the Longnan Population of the Cabbage Beetle, Colaphellus bowringi Baly( Coleoptera:Chrysomelidae)
摘要
Abstract
To ascertain the effects of photoperiod and temperature on diapause induction in the Longnan population of the cabbage beetle,Colaphellus bowringi Baly,photoperiodic responses were systematically inves-tigated at different constant temperatures.The results showed that the cabbage beetle is a short-day species but its photoperiodic response highly depends on temperature.All adults entered diapause at ≤18 ℃ regardless of photoperiods.High temperatures strongly weakened the diapause-inducing effects of long daylengths. The dia-pause-averting influence of short daylengths was expressed only at high temperatures(above 18℃).By transfer-ring from a long day to a short day or vice versa at different times after hatching,it was shown that the sensitive stage with regard to photoperiod was the larva,and a long day was photoperiodically more potent than a short day.Its sensitive stage to temperature encompassed the larval,pupal and adult stages.关键词
