摘　　要：蝽类昆虫破卵器属于脱落型额部破卵器。对我国半翅目异翅亚目陆栖组其中10科30余属50多种蝽类卵的破卵器在扫描电镜下进行了观察比较。陆栖组蝽类卵的破卵器可分为蝽型、缘蝽型及臭虫型三种类型。本文就前两种类型破卵器形态及细微构造特征对比,研究了破卵器在属、种间的差异,为系统分类、胚胎发育及细微形态特征方面提供新的依据。The fine structure of egg-bursters of over 50 terrestrial bugs were observed with scanning electron microscope; they belong to Pentatomidae, Plataspidae, Coreidae, Berytidae, Aradidae, Stenocephalidae, Lygaeidae, Pyrrhocoridae, Anthocoridae and Reduviidae. The egg-burstars can be grouped into three types according to the taxa Pentatornorpha, Coreiomorpha and Cimicomorpha. The former two types are usually 'T' or 'Y'-shaped, notably in species with thick corion. Pentatomidae and Plastaspidae have more strongly sclerotized egg-bursters than Lygaeidae and Pyrrhocoridae which have thinner corion. The third type is conspicuously different from both of them in shape and structure. In Pentatornorpha marked difference exists in chorion sculpture and shape of egg-bursters among the genera such as Scotinophara, Nezara, Iphiartua and Pitcdia. Generally, the fine structure of the egg-bursters is related to the structure and thickness of chorion and its way of splitting.
