摘　　要：利用扫描电子显微镜对蜂巢小甲虫(Aethina tumida)雌雄成虫触角感器类型、形态特征及分布特点进行观察,结果表明,蜂巢小甲虫雌雄触角感器类型、数量和分布相似。成虫触角上分布有8种感器(21种亚型),分别为毛形感器(3种亚型)、锥形感器(6种亚型)、刺形感器(4种亚型)、栓锥形感器(2种亚型)、腔锥形感器(2种亚型)、腔形感器(1种)、耳形感器(2种)、Bohm氏鬃毛(1种),其中毛形感器和锥形感器数量最多。此外,触角上还着生少量表皮孔。雌虫触角上毛形感器ST3,锥形感器SB1、SB2、SB3,刺形感器SC1,腔锥形感器SCo1,耳形感器SA1、SA2长度显著长于雄虫,而锥形感器SB4、SB5,腔锥形感器SCo2显著短于雄虫。雌虫触角上毛形感器ST3,锥形感器SB2、SB3、SB4基部直径显著长于雄虫,而锥形感器SB6显著短于雄虫。The morphology and distribution of antennal sensillain female and male adults of Aethina tumida were observed using scanning electron microscopy.The results showed that there was a little difference in the types,distribution,and number of the antennal sensilla between female and male adults.Eight types of sensilla(21 subtypes)were identified on the antennae,including sensilla trichodea(ST,3 subtypes),sensilla basiconica(SB,6 subtypes),sensilla chaetica(SC,4 subtypes),sensilla styloconica(SS,2 subtypes),sensilla coeloconica(SCo,2 subtypes),sensilla cavity(SCa),sensilla auricillica(SA,2 subtypes)and b hm bristles(BB).Sensilla trichodea and sensilla basiconica were the most abundant types.Furthermore,cuticular pores were observed on the antennae.The length of ST3,SB1,SB2,SB3,SC1,SCo1,SA1 and SA2 were significantly longer in females than in males,while those of SB4,SB5 and SCo2 were significantly shorter in females than in males.The basal diameter of ST3,SB2,SB3 and SB4 was significantly longer in females than in males,while that of SB6 was significantly shorter in females than in males.
