摘　　要：以采自腾冲市洞山乡的棕色型和黑色型九香虫为研究对象,通过扫描电镜观察2种色型九香虫雌、雄成虫触角形态及触角感器超微结构,探讨2种色型九香虫成虫触角感器的类型、分布及超微形态。结果表明:2种色型九香虫成虫均为丝状触角,由柄节、梗节和鞭节组成,其中鞭节又可分为3个鞭小节;同种色型雌雄间及不同色型相同性别间触角长度不同;棕色型九香虫雌虫触角长度(8433.88μm)显著长于雄虫触角长度(8162.21μm),黑色型九香虫雌虫触角长度(8315.41μm)显著长于雄虫触角长度(8106.54μm),棕色型雌虫与黑色型雌虫触角长度无显著差异,棕色型雄虫触角长度显著长于黑色型雄虫;2种色型九香虫有7种类型触角感器,分别为毛形感器、刺形感器、锥形感器、具弯钩形感器、腔形感器、圆柱形感器和腔锥形感器,其中5种类型为2种色型共有,以毛形感器的数量最多,分布范围最广;同种色型雌雄间及2种色型间触角各节长度、感器类型和分布均存在一定差异。本研究首次在半翅目异翅亚目昆虫触角上观察到圆柱形感器的存在,为进一步研究九香虫与环境的相互关系、探明九香虫寄主选择行为机制和开展人工繁育提供参考。To understand the type,distribution and ultrastructure of antennal sensilla of 2 color types of adults Coridius chinensis.The antennal morphology and ultrastructure of the female and male adults from 2 color types of C.chinensis were observed by scanning electron microscopy with brown and black C.chinensis in Dongshan Township,Tengchong City.The findings indicated that the antennae of C.chinensis were linear with 5 segments and composed by scape,pedicel and flagellum.The length of antennae was different between 2 color types and sexes.The antennal length of female from brown type was 8433.88μm,which was significantly longer than that of the male antennal length 8162.21μm,and the antennal length of female from black type was 8315.41μm that was also significantly longer than that of the male antennal length 8106.54μm.There was no significant difference in antennal length of female adults between 2 types while the antennal length of male adults between 2 types was significantly different.There were 7 antennal sensilla types from 2 color types of C.chinensis,including sensilla trichoidea,sensilla chaetica,sensilla basiconca,sensilla bent-tipped,sensilla cavity,sensilla cylindrical and sensilla coeloconica,among which 5 antennal sensilla types were shared by 2 color types.The sensilla trichoidea had the largest number and the widest distribution range.There were some differences on the antennae length,types and distribution of the antennal sensilla between 2 color types and sexes.Moreover,the sensilla cylindrical was observed for the first time on the antennae of Heteroptera insects.The results of this study provide a basic reference for further study of the relationship between C.chinensis and environment and the mechanism of host selection and the large-scale artificial breeding of C.chinensis.
