利用扫描电镜和透射电镜观察了东亚飞蝗(Locusta migratoria manilensis)不同类型触角感受器的超微结构.在触角上存在4种类型的感受器:锥形感受器、毛形感受器、腔锥形感受器和刺形感受器.锥形感受器分为两个亚型:A亚型壁薄多孔,有100多个树突分枝,每个分枝有l～5个微管;B亚型壁薄,只有少于6个树突分枝.毛形感受器单壁,壁上有沟和小孔,孔数相对较少.对感受器腔中有超过20个的树突,每一树突中含有1～5个微管.腔锥形感受器位于触角表皮凹陷当中,含两个亚型:A亚型双壁,壁上有沟和放射状的孔,6～7个树突.B亚型含4个树突,单壁,壁上无孔无沟.刺形感受器壁厚无孔,有5个树突连接顶端小孔.对感受器的功能讨论认为:锥形和毛形感受器是嗅觉感受器;腔锥形感受器可能感受化学和温湿度刺激;刺形感受器可能是味觉或机械感受器.

The ultrastructures of different types of antennal sensilla in Locusta migratoria manilensis were investigated by scanning and transmission electron microscopy. There are four types of sensilla on its antenna: namely, sensilla basiconica, sensilla trichodea,sensilla coeloconica and sensilla chaetica. Sensilla basiconica have two subtypes: subtype A has thin cuticular wall perforated by numerous pores and more than 100 dendritic branchings, each of which contains 1～5 microtubules. Subtype B has also thin wall but much fewer(less than 6) dendritic branchings. Sensilla trichodea are single-walled and grooved. There are relatively few pores on the wall. More than 20 dendrites, each of which contains 1～5 microtubules, can be found in the sensillar lumen. Sensilla coeloconica are situated in pits on the antennal surface and divided into two subtypes: subtype A has grooved surface and double sensillar walls perforated by radial pores and 6～7 dendrites. Subtype B contains 4 dendrites with non-grooved, non-porous single wall. Sensilla chaetica have a thick non-porous wall and contain 5 dendrites sent to a terminal pore. The functions of four types of sensilla were discussed that sensilla basiconica and sensilla trichodea are olfactory sensilla; sensilla coeloconica may be respond to chemo-, hygroand thermostimulation and sensilla chaetica are possibly gustatory or mechanoreceptors.
