摘　　要：【目的】探明暗期不同光源的光周期和温度对丝棉木金星尺蛾Calospilos suspecta滞育诱导、发育时间和蛹重的影响。【方法】25℃和28℃室温时,分别测试暗期无光、暗期红光和暗期黄光各6个光周期下滞育率、滞育蛹对应的幼虫期、蛹重和蛹期。【结果】(1)各试验条件下均诱导了滞育,28℃时滞育率多高于25℃,且28℃时暗期红光和黄光提高了滞育率;(2)25℃下所得滞育蛹对应的幼虫期多长于28℃;(3)28℃下所得滞育蛹多重于25℃;(4)各试验条件下所得滞育蛹的蛹期不一致,25和28℃下12L∶12D、11L∶13D共4个处理组蛹期在120 d以上;25℃下12L∶12D和11L∶13D处理组滞育蛹的蛹期分别是84.6 d和86.1 d;其余30个处理组滞育蛹的平均蛹期在37-67 d。【结论】试验条件下丝棉木金星尺蛾滞育生物学特性较为复杂,受光照、温度及光温互作的影响;从滞育蛹的蛹期来看,2个温度下短光照(12L∶12D和11L∶13D)诱导了冬季滞育,25℃时12L∶12R和11L∶13R处理组滞育蛹蛹期介于冬季滞育和夏季滞育之间,其余30个处理组诱导了夏季滞育。[Objectives]To understand the effects of creating artificial photoperiods with different light sources,and temperature,on diapause induction,development and pupal weight in Calospilos suspecta.[Methods]Newly hatched larvae were exposed to different photoperiods created using different light sources during the dark phase at either 25 and 28℃in a laboratory.The diapause rate,duration of the larval period,pupal weight and duration,of diapausing pupae were measured and compared.[Results](1)Some pupae in each treatment group entered diapause,but the diapause rate at 28℃was higher than that at 25℃in most treatment groups.The diapause rate increased when red or yellow LEDs were used as the light source.(2)The duration of the larval period at 25℃was longer than that at 28℃in most treatment groups.(3)Diapausing pupae were heavier at 28℃,than at 25℃.(4)The duration of diapause varied between treatment groups.It was longer than 120 d in the 12L∶12D and 11L∶13D groups at either 25 or 28℃.However,at 25℃,diapause duration was 84.6 and 86.1 d in the 12L∶12D and 11L∶13D groups,respectively.Diapause duration in the other 30 treatment groups was 37-67 d.[Conclusion]Diapause in C.suspecta was complex and influenced by light source,temperature,and the interaction between these factors.Winter diapause was induced by photoperiods of 12L∶12D and 11L∶13D at either 25 or 28℃.However,the duration of diapause induced by these photoperiods at 25℃was intermediate between that of winter and summer diapause.Summer diapause was induced in the other 30 treatment groups.
