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cephusfumipenniseversmann，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。关键词灰翅麦茎蜂，蛹，分级预测法studyonthedevelopmentalgradesofpupaofcephusfumipenniseversmannchenalan*chenhailong(agricultureandanimalhusbandrycollegeofqinghaiuniversity,xining810016,china)abstractobservationofthedevelopmentoflaboratorybredpupaeofcephusfumipenniseversmannindicatesthatthepupalperiodlasts（30±208）dandcanbedividedinto5stages（i,ⅱ,ⅲ,ⅳ,ⅴ)accordingtothecolorofapupa’sbody.thesestageslast（65±055)d，（39±048）d，（44±05）d，（46±049）dand（105±104）drespectively.basedontheseobservations,theoptimaltimetocontroladultc.fumipenniscanbepredicted.keywordscephusfumipennis,pupa,gradespredictedmethod
