蔗扁蛾触角扫描电镜观察

Scanning Electron Microscopy Observation on Antennal Sensilla of Opogona sacchari

用扫描电子显微镜对蔗扁蛾触角感器的观察结果表明:蔗扁蛾触角上共分布有6种感器,它们是毛形感器、刺形感器、锥形感器、具缘毛腔锥感器、鳞形感器和端毛.其中鳞形感器的着生方式与其它昆虫有明显的区别,从正面看只有一个感器,但在它的下面还有3～5个感器,而且每组相互排列非常整齐有规律.

Six types of sensilla on the antenna of Opogona sacchari were found by scanning electron microscopy. They are trichoid sensillum, sensillun basiconicum, sensillum chaeticum, terminal hair, sensillum coeloconicum, sensilla squamiformia. Location of sensilla squamiformia was different to other insects, there may be one sensilla squamiformia in each sensina group at top view, but in fact there are 4 to 6 sensilla squamiformia in each group at lateral view.
