我国樟树五种常见粉虱超微结构

The ultrastructure of five species of whitefly on Cinnamomum camphora in China

应用扫描电子显微镜(SEM)对我国樟树Cinnamomum camphora上5种主要粉虱的第四龄若虫(伪蛹)超微形态结构特征进行系统观察和描述,并对其主要形态特征进行比较,编制检索表。这5种粉虱是樟刺粉虱Aleurocanthus cinnamomi(Takahashi)、黑刺粉虱Aleurocanthus spiniferus(Quaintance)、山枇花棒粉虱Aleuroclava gordoniae(Takahashi)、台湾高山粉虱Aleuroclava montanus(Takahashi)和天目山棒粉虱Aleuroclava tianmuensis(Wang&Dubey),其中台湾高山粉虱和天目山棒粉虱为樟树上新记录。

The ultrastructure of the forth instar nymph(pupal case)of five whitefly species on Cinnamomum camphora,i.e.,Aleurocanthus cinnamomi,Aleurocanthus spiniferus,Aleuroclava gordoniae,Aleuroclava montanus and Aleuroclava tianmuensis,were observed using scanning electron microscope(SEM),with description and comparison of morphological characteristics presented,and the identification key was provided for these species.A.montanus and A.tianmuensis were two newly recorded pests on C.camphora.
