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(8433.88 μm)显著长于雄虫触角长度(8 162.21 μm),黑色型九香虫雌虫触角长度(8 315.41 μm)显著长于雄虫触角长度(8 106.54μm),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.
Abstract
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 8 433.88 μm,which was significantly longer than that of the male antennal length 8 162.21 μm,and the antennal length of female from black type was 8 315.41 μm that was also significantly longer than that of the male antennal length 8 106.54 μm.There was no significant differ-ence 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 trich-oidea 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 cyl-indrical 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.
