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 microstructures of male and female genitalia of Locusta migratoria manilensis (Meyen) were observed by scanning electron microscopy. The specific structures of male and female genitalia and the distribution of receptors on the surface were described. Female genitalia by the back, abdomen produced eggs, the male genitalia by the exoskeleton of the sun-based film-backed back and posed complex. In the male and female external genital surface is born with a large number of receptors, including hairy, stab-shaped, tapered, mainly mechanical sensors, as well as a small amount of chemoreceptors.
