榕透翅毒蛾成虫触角结构与感器的扫描电镜观察
Observation on antenna structure and sensilla of Perina nuda adults with scanning electron microscope
摘要
Abstract
To clarify the types,morphological characteristics,and distribution patterns of the antennal sensilla of Perina nuda,the antennae of adult P.nuda were observed in detail with scanning electron microscope.The results showed that the antennae of both male and female adults consisted of three parts:the scape,pedicel,and flagellomeres.The antennae lengths of female and male adults were(6.93±0.85)mm and(5.49±0.59)mm,respectively.The flagellomeres exhibited the richest variety and number of sensilla.A total of ten types and 12 subtypes of sensilla were identified,including sensilla trichodea(three subtypes),sensilla chaetica,sensilla coeloconica,sensilla auricillica,sensilla styloconica,sensilla basiconica,sensilla squamiformia,Böhm bristles,sensilla mammilliformia,and smell pore.Significant sexual dimorphism was observed in some sensilla of P.nuda adults.The length and basal diameter of sensilla trichodea(Ⅰ,Ⅱ,Ⅲ)and sensilla mammilliformia in males were significantly greater than those in females.In contrast,the length of Böhm bristles,sensilla basiconica,and sensilla styloconica,as well as the basal diameter of sensilla styloconica and sensilla auricillica,were significantly greater in female adults than those in male adults.Results provide a morphological foundation for further investigation into the functions of the antennal sensilla in P.nuda.关键词
