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(Stl)]、二星蝽[Stollia guttiger(Thunberg)]、红脊长蝽[Tropidothorax elegans(Distant)]和瘤缘蝽[Acanthocoris 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 (Stl),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.
