摘　　要：双翅目叶蝇科真叶蝇亚科真叶蝇属成虫触角第1鞭节和下颚须极度膨大,其表面感受器的形态和功能缺乏系统研究。为了明确其超微结构、类型和分布情况,利用扫描电子显微镜对该属2个代表种,黑三角真叶蝇和广西真叶蝇的成虫触角感受器和下颚须感受器的超微形态结构进行观察和研究。结果表明,这2种叶蝇种类触角感受器种类基本相同,且雌雄无太大差别,共存在5种感受器,分别为毛形感器、锥形感器I、锥形感器II、刺形感器和鬃形感器;下颚须具4种感受器,分别为毛形感器、刺形感器、锥形感器II和鬃形感器。对两种真叶蝇的触角和下颚须各种感受器的形态、分布特点进行了描述,并对其功能进行了一定的探讨,感受器种类无太大差别,仅数量和分布有所差别。The genus Phyllomyza of subfamily Phyllomyzinae with extremely enlarge first flagellomere and palpus,the morphology and function of the sensilla are poorly known.Therefore,the external form,types and distribution of sensilla on the antennae and palpus of Phyllomyza peceusa and Phyllomyza guangxiensis were observed by scanning electron microscope.In this study,we described the ultra-morphology of sensilla on the adult antennae and palpus.Five types of antennae sensilla were found:sensilla trichodea,sensilla basiconica type I,sensilla basiconica type II,sensilla chaeticaand sensilla achaetiea.Meanwhile,there were four types of palpus sensilla,including sensilla trichodea,sensilla chaetica,sensilla basiconica type II and sensilla achaetiea.The morphology and distribution of the various receptors of antennae and paplus of the two species were described.Moreover,their functions were discussed.We found there was no difference of the sensilla types between antenna and palpus except for the numbers and distribution.
