二点委夜蛾触角感器的超微结构研究

对二点委夜蛾成虫触角感器的形态结构进行了扫描电镜观察,结果表明:二点委夜蛾触角由柄节、梗节和鞭节组成,鞭节由72个亚节组成,触角内侧面覆盖有鳞片。雌蛾触角上存在9种感器:毛形感器、刺形感器、耳形感器、腔锥形感器、锥形感器、栓锥形感器、腔乳头状感器、鳞形感器和Bhm氏鬃毛。不同感器在触角各节上的分布与数量各不相同,且雌雄之间存在差异。鳞形感器为雌蛾特有,雄蛾触角上的毛形感器多于雌蛾,腔锥感器少于雌蛾。

The ultrastructures of the antennal sensilla of Athetis lepigone

The morphology and ultrastructure of antennal sensilla of Athetis lepigone were observed under scanning electron microscope. The antennae of Athetis lepigone were made up of scapus, pedicel and flagella with the latter consisting of 72 segments. The antennae of female moth contained nine kinds of antennal sensilla, namely sensilla trichodea, sensilla chaetica, sensilla auricillica, sensilla coeloconica, sensilla basiconica, sensilla styloconica, sensilla cavitata-peg, sensilla squamiformia and B?hm bristles. The distribution and quantity of each sensillum, however, were different in different segments of the antennae. The antennae of male moth contained all of the above nine antennal sensilla except sensilla squamiformia, while the number of sensilla coeloconica was less than that of the female.
