三种粉虱触角、口针及跗节感受器的超微结构观察

Ultra-structure of the antennal,stylet,and tarsal sensilla of three whiteflies:Bemisia tabaci,Trialeurodes vaporariorum,Alenrocybotns indice(Homoptera:Aleyrodidae)

对烟粉虱Bemisia tabaci、温室白粉虱Trialeurodes vaporariorum和禾粉虱Aleurocybotus indicus3种粉虱的触角、口针及跗节感受器的超微结构进行了观察。利用扫描电镜观察了烟粉虱、温室白粉虱和禾粉虱3种粉虱触角、口针及跗节化学感受器的类型和分布,进行了比较。3种粉虱触角上都有刚毛感受器、锥形感受器2种感受器和微毛,烟粉虱触角还有钟形感受器和腔锥感受器;温室白粉虱和禾粉虱触角均没有发现钟形感受器;3种粉虱的口针和跗节上均只有刚毛感受器和微毛,且形态结构相似。

Scanning electron microspcopy was used to reveal the morphology and detailed ultra-structure of the antenna,stylet,and tarsal sensilla of three whiteflies;Bemisia tabaci,Trialeurodes vaporariorum,Alenrocybotns indice.All three species have microtrichia and 2 sensilla,i.e.chaetae sensilla and basiconic sensilla on the antennae.B.tabaci has 2 other types of sensilla on the antennae：campaniform sensilla and coebconic sensilla,but no campaniform sensilla were found on the on the antennae of T.vaporariorum and A.indice.All three species have similar morphological characteristics of microtrichia and chaetae sensilla on stylet,and tarus.
