桃红颈天牛触角、口器及跗节感器的超微结构特征

Ultrastructure of sensilla on the antennae,mouthparts and tarsi of Aromia bungii(Cerambycidae:Cerambycinae)

本文采用扫描电子显微镜技术,利用ImageJ软件测量,观察并获取了桃红颈天牛Aromia bungii雌雄成虫触角、口器及跗节感器的长度、数量和分布情况。研究结果表明,雌雄成虫触角均发现有感器类型5型17亚型,即刺形感器8亚型、锥形感器5亚型、毛形感器2亚型、耳形感器以及B9hm氏鬃毛各1亚型。雌雄成虫口器均分布有感器类型6型10亚型,即刺形感器2亚型、锥形感器4亚型、毛形感器、钟形感器、板形感器以及B9hm氏鬃毛各1亚型。雌雄成虫跗节表面均有感器类型3型6亚型,即刺形感器3亚型、锥形感器2亚型以及毛形感器1亚型,且雌雄虫间各部位感器无性二型现象。

We obtained and examined the length,number and distribution of sensilla on antennae,mouthparts and tarsi in male and female adults of Aromia bungii(Faldermann,1835)using scanning electron microscopy and ImageJ software.The results showed that there were 5 types and 17 subtypes of sensilla on the antennae of both male and female adults,including 8 subtypes of sensilla chaetica(SC),5 subtypes of sensilla basiconica(SB),2 subtypes of sensilla trichodea1(ST1),1 sensilla auricillica(SA)and 1 B hm bristles(BB).6 types and ten subtypes sensilla were identified from mouthparts of male and female,including 2 subtypes of sensilla chaetica(SC),4 subtypes of sensilla basiconica(SB),1 sensilla coeloconica(SCo),1 sensilla placodea(SP)and 1 B hm bristles(BB).In addition,3 types and 6 subtypes of sensilla were described on the tarsi of male and female,including 3 subtypes of sensilla chaetica(SC),2 subtypes of sensilla basiconica(SB)and 1 sensilla trichodea 1(ST1).There was no difference in the sensilla between males and females.
