摘　　要：利用扫描电镜技术观测了东亚飞蝗Locusta migratoria manilensis(Meyen)雌雄个体外生殖器的显微构造,描述了雌雄两性外生殖器的具体结构以及其表面上感受器的分布情况。雌性的外生殖器由背、腹产卵瓣构成,雄性的外生殖器由外骨骼所包被的阳具基背片和阳具复合体构成。在雌雄两性的外生殖器表面着生有大量的感受器,包括毛形、刺形、锥形,主要是机械感受器,还有少量化学感受器。The microstructureof the external genitaliaof Locusta migratoria manilensis （Meyen）was observed using scanning electron microscopy. The specific appearance of structures and sensilla distribution on the external genitalia in both sexes was compared. The female external genitalia consist of dorsal and ventral oviposition valvules, while the male genitalia consist of an epiphallus enclosed by exoskeleton and a penis. On the visible surfaces of the external genitalia are many sensillae, including trichoid sensillae、chaeticum sensillae and cone sensillae. The sensillae are mainly mechanical sensillae but a few are chemical sensillae.
