桃小食心虫伪产卵器感器的超微结构

Ultrastructures of Sensillia on Pseudovipositor of Carposina sasakii

为掌握桃小食心虫雌虫的产卵机制及规律,为桃小食心虫防治提供理论依据,采用扫描电镜对其雌虫伪产卵器感器的形态进行观察。结果表明:雌虫产卵器上共发现7种感器,分别为毛形感器、刺形感器、锥形感器、Bhm式鬃毛、芽孢感器、乳状感器以及分泌孔。

In order to grasp the oviposition mechanism and regulation of C.sasakii,and provide a theoretical basis for the prevention and control,the appearance and distribution of sensilla on pseudovipositor of C.sasakii were observed with a scanning electron microscope.The results showed that sensilla were of seven types：sensilla trichodea,sensilla chaetica,sensilla basiconica,Bhm bristles,sensilla mammilliformia,Bud-shaped sensilla and smell pore.
