摘  要：
扫描电镜观察表明,蝗总科3科5属7种蝗虫下颚须共存在6种感受器,其中毛形感受器Ⅰ型和Ⅱ型以及刺形感受器和锥形感受器是7种蝗虫所共有的。柱形感受器I型为剑角蝗科的僧帽佛蝗(Phlaeoba infumata)和长角佛蝗(P.antennate)所特有,而柱形感受器II型则是斑翅蝗科的花胫绿纹蝗(Aiolopus tamulus)所特有的。因此感受器的种类及其形态特征也许能成为鉴别蝗总科不同科和属的有用特征。蝗虫下颚须上不同感受器的种类和数量,可为蝗虫取食、接受内外不同的物理和化学刺激等方面起到重要作用。

摘  要：
The sensilla on the maxillary palpus of the seven grasshoppers belonging to 3 genera and 3 families were examined with scanning electron microscopy.Six types of sensilla on the maxillary palpus were observed,i.e.sensilla trichodea Ⅰ and Ⅱ,sensilla chaetica,sensilla basiconca and sensilla cylindric Ⅰ and Ⅱ.Sensilla trichodea was divided into two subtypes: subtype Ⅰ and subtype Ⅱ.All the seven grasshoppers had sensilla trichodea Ⅰ and Ⅱ subtypes,sensilla chaetica and sensillun basiconica.Phlaeoba infumata and P.antennate of Acrididae had the sensilla cylindric subtype Ⅰ,while only Aiolopus tamulus of Oedipodidae had the sensilla cylindric subtype Ⅱ.Therefore,types and morphological features of sensilla may become useful features to identify different families and genera.The different types and quantities of sensilla on the maxillary palpus of grasshoppers can be of an important use in feeding,accepting different internal and external physical and chemical stimulation.
