摘要：
Objective: This study aimed to clarify the types, quantity, distribution and ultrastructure of antenna sensilla in adults of Anacampsis populella.Method: The antenna sensilla in female and male adults of A. populella were observed with scanning electron microscope.Result: Most of antennal sensilla were confined to ventral and lateral surface of the flagellum, while the minority was on scape and pedical. Based on the external morphology of the sensilla,it was able to be classified into eight types: BÖhm bristles (two subtypes, BBⅠ and BBⅡ), trichodea, basiconica (two subtypes, SBⅠ and SBⅡ), chaetica, coeloconica, auricillica, squamiformia and styloconica. Among them, trichodea, basiconica and auricillica were multiporous on cuticle, which were considered to be olfactory organ. There was no difference in morphology and distribution of the sensilla between male and female moths, but the flagellum of male antennae had 1-4 segments more than female moth. The sensilla trichodea and sensilla basiconicaⅡ of male moth were significantly longer than those of female moth. The basal diameter of sensilla chaetica and sensilla coeloconica was significantly wider than that of female moth. In addition, the amount of sensilla trichodea, basiconica, coeloconica, squamiformia and chaetica of male was significantly more than those of female.Conclusion: The antennal sensilla of A. populella were abundant, and most of them had olfactory function. There was sexual dimorphism in number and sensilla characteristics between male and female. © 2019, Editorial Department of Scientia Silvae Sinicae. All right reserved.
