9种农林有害蝽类昆虫高龄若虫龄期的区分

摘要

对9种主要为害果树、林木、蔬菜、稻麦、烟草、药草等植物有害蝽类昆虫高龄若虫龄期区分进行了研究，各种类的1～5龄若虫及成虫标本均通过田间采集和室内饲养方法获取。通过对不同种类若虫进行形态特征的比较形态学研究，提供了3～5龄若虫间的鉴别特征。9种有害蝽象分别为：华麦蝽Aelia nasuta Wagner、斑须蝽Dolycoris baccarum （L．）、麻皮蝽 Erthesina fullo （Thunberg）、菜蝽Eurydema dominulus （Scopoli）、横纹菜蝽Eurydema ge-bleri Kolenati、茶翅蝽 Halyomorpha halys （Stål）、二星蝽Stollia guttiger （Thunberg）、红脊长蝽Tropidothorax el-egans （Distant）、瘤缘蝽Acanthocoris scaber （Linnaeus）。%The recognition of nymph in late instar stages of nine harmful stinkbug species mainly damaging fruit trees,vegetables,rice,wheat,tobacco and herbs was conducted.The various species of 1st to 5th instar nymph and adult specimens were obtained from field collection and indoor breeding.Through the morphological charac-teristics comparison among different nymphal species,the identification features of 3rd to 5th instar nymphs were provided.Nine harmful stinkbug species are as follows:Aelia nasuta Wagner,Dolycoris baccarum (L.),Erthesina fullo (Thunberg),Eurydema dominulus (Scopoli),Eurydema gebleri Kolenati,Halyomorpha halys (Stål),Stollia guttiger (Thunberg),Tropidothorax elegans (Distant)and Acanthocoris scaber (Linnaeus).
