文章标题：灰翅麦茎蜂蛹的发育分级研究

（青海大学农牧学院西宁810016）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。

AbstractObservation 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.
