摘要
应用扫描电镜对西藏飞蝗Locusta migratoria tibetensis Chen触角的外部形态结构及其感器进行了观察和研究。结果表明,西藏飞蝗触角上存在5种感器即毛形感器、刺形感器、腔锥形感器、锥形感器和腔形感器。通过对各种感器的形态特点进行描述,发现西藏飞蝗群居型与散居型、蝗蝻与成虫、雌性与雄性的感器在类型上无明显差异,但是群居型较散居型在数量上偏少;蝗蝻较成虫在形态上偏小、数量上偏少,主要集中分布位置也有所不同。与东亚飞蝗L.migratoria manilensis(Meyen)相比,二者在感器类型上无明显差异,但西藏飞蝗触角感器在形态上较东亚飞蝗偏小,数量上偏少,分布情况也有所差别。
Scanning electron microscopy was used to observe the antennae and sensilla of Locusta migratoria tibetensis Chen.Five types of sensilla were found on antennae： sensilla trichodea,sensilla chaetica,sensilla coeloclnica,sensilla basiconica and sensilla cavity.Describing the morphological characteristics of these sensilla indicates that there was generally little variation in sensilla type,however,gregarious locusts had fewer sensilla than solitary locusts.Nymphs had smaller and fewer sensilla than adults,and nymphs and adults also differed in the distribution of sensilla.L.m.tibetensis had similar types of sensilla to L.m.manilensis （Meyen） but these subspecies differ in the morphological characteristics,quantity and distribution of sensilla,such as differences in distribution of sensilla between nymphs and adults.
