大辟缘蝽触角感器的扫描电镜观察
为了解大辟缘蝽（Prionolomia gigas Distant）触角感器与其嗅觉感受机制的关系，采用扫描电镜观察大辟缘蝽雌、雄成虫触角感器类型、超微形态及其分布。结果表明：大辟缘蝽雌、雄成虫触角均呈线状，由柄节、梗节和鞭节 3 部分组成；雌、雄成虫触角上共观察到6种类型感器，分别为毛形感器、刺形感器、锥形感器、腔形感器、腔锥形感器和具弯钩型感器，其中，以毛型感器数量最多、分布范围最广，鞭节上的感器类型较柄节和梗节丰富，雌虫的感器类型多于雄虫，表现出明显的性二型现象。

Scanning electron microscopic observation of sensilla on the antennae of Prionolomia gigas Distant
In order to understand the relationship between antennal sensilla of Prionolomia gigas Distant and their olfactory sensory functions, scanning electron microscope was used to examine the types, ultrastructure and distribution patterns of the antennae sensilla from the male and female adult of P. gigas. The results showed that the antennae of P. gigas were filiform and formed of scape, pedicel and flagellum. The length of each segment and the total length of antennae of male and female adults were different. Six sensilla types were observed on antennae of female and male adults, including trichodea sensilla, chaetica sensilla, basiconca sensilla, cavity sensilla, coeloconic sensilla and bent-tipped sensilla. The type of trichodea sensilla was the most numerous and had the widest distribution on antennae. Sensilla in the flagellum were much more abundant than that on scape and pedicel. There was obvious dimorphism that the female of P. gigas had more sensilla types than the male.
