田间常见8种有害蝽类若虫龄期的区分

摘要

本文采集了田间常见的8种有害蝽类，华麦蝽（Aelia nasuta Wagner）、斑须蝽[Dolycoris baccarum （Linn．）]、菜蝽[Eurydema dominulus （Scopoli）]、横纹菜蝽（Eurydema gebleri Kolenati）、茶翅蝽[Halyomorpha halys （Stl）]、二星蝽[Stollia guttiger （Thunberg）]、红脊长蝽[Tropidothorax elegans （Distant）]和瘤缘蝽[Acan-thocoris scaber （Linn．）]。经过室内饲养获得其1～5龄若虫及成虫。通过对不同龄期若虫形态特征的比较形态学研究，确定了不同龄期若虫的鉴别特征，特别是低龄若虫的识别特征。%The specimens of adults and first to five instars nymph of eight stinkbugs,including Aelia nasuta Wag-ner,Dolycoris baccarum (Linn.),Eurydema dominulus (Scopoli),Eurydema gebleri Kolenati,Halyomorpha halys (Stl),Stollia guttiger (Thunberg),Tropidothorax elegans (Distant)and Acanthocoris scaber (Linn.),were ob-tained by field collection and rearing.The identifying characteristics of nymph of various instars,especially for the lower instar nymphs,were recommended by comparative morphology.
