蚱科7种昆虫触角感受器的形态与分布

Fine Structure and Distribution of the Antennae Sensilla of 7 Species(Tetrigidae)

摘要: 报道了蚱科(Tetrigidae)7种昆虫的触角感受器的形态与分布的扫描电镜观察结果.蚱科昆虫的触角感受器数量与类型较少,仅有芽孢形感受器I、芽孢形感受器II、腔形感受器和板形感受器4种类型,其中以板形感受器数量最多.通过对7种昆虫的雌性个体触角感受器在触角各节上的分布情况的分析,发现蚱科昆虫的触角感受器主要分布于触角的端部及中段节次上,其中以板形感受器的分布最为明显,主要集中分布于第10—15节触角上.

Abstract: The antennae sensilla of 7 Tetrigidae species are studied using scanning electron microscopy.There are only four types of sensilla,named sporangium sensilla I,sporangium sensilla II,cavity sensilla and placoid sensilla.The placoid sensilla has the most large quantity in all four types of sensilla.The most sensillae are mainly distributed in the central and terminal segment of antennae.This structure of distribution is exactly expressed in placoid sensilla which is distributed from tenth segment ..
