摘　　要：室内饲养了灰翅麦茎蜂Cephus fumipennis Eversmann,对该种蛹的发育进行了研究。结果表明,灰翅麦茎蜂蛹期(30±2.08)d,根据蛹体色的显著变化分为5级(Ⅰ,Ⅱ,Ⅲ,Ⅳ,Ⅴ),其历期依次为:(6.5±0.55)d、(3.9±0.48)d、(4.4±0.5)d、(4.6±0.49)d和(10.5±1.04)d。通过蛹的发育进度和分级预测法研究,可预测灰翅麦茎蜂成虫的防治适期。Observation of the development of laboratory-bred pupae of Cephus fumipennis Eversmann indicates that the pupal period lasts（30±2.08）d and can be divided into 5 stages（I,Ⅱ,Ⅲ,Ⅳ,Ⅴ） according to the color of a pupa＇s body.These stages last（6.5±0.55）d,（3.9±0.48）d,（4.4±0.5）d,（4.6±0.49）d and（10.5±1.04）d respectively.Based on these observations,the optimal time to control adult C.fumipennis can be predicted.
