Abstract:

研究金纹细蛾(Lithocolletis ringoniella Matsumura)触角形态、感器的种类、数量和分布,为研究触角感器的功能、寄主选择机制以及利用性诱剂控制金纹细蛾提供形态学依据。通过扫描电镜对金纹细蛾雌虫、雄虫触角形态和感器进行观察,在金纹细蛾雌、雄成虫触角上共观察到 7 种感器,分别为毛形感器(Sensilla trichoidea,ST)、刺形感器(Sensilla chaetica,SCh)、锥形感器(Sensilla basiconica,SB)、腔锥形感器(Sensilla coeloconica,SCo)、栓锥形感器(Sensilla styloconica,SS)、鳞形感器(Sensilla squamiformia,SQ)、Bhm氏鬃毛(Bhm bristles,BB),在雄成虫触角上除观察到上述 7 种感器外,还观察到畸形锥形感器(Malformed sensilla basiconica,MSB)。金纹细蛾雌雄成虫感器的形态与分布在两性间无明显差异,金纹细蛾触角上的感器呈现稳定的规律性分布。
The purpose of this study on morphology of antenna, kind, quantity and distribution of sensilla of Lithocolletis ringoniella Matsumura is to provide foundation for function of antennal sensilla, mechanism of host selection and controlling L.ringoniella by sex pheromone. Scanning electron microscope was used to observe antennal morphology, sensilla of females and males seven kinds of sensilla were discovered in the sensilla of females,including sensilla trichoidea(ST), sensilla chaetica(SCh), sensilla basiconica(SB), sensilla coeloconica(SCo), sensilla styloconica(SS), sensilla squamiformia(SQ), bhm bristles(BB), one more kind of sensilla, malformed sensilla basiconica(MSB) was observated in males and females. No obvious difference in morphology and distribution of sensilla between sexes and the antennal sensilla of L.ringoniella was regularly distributed.
