黑尾叶蝉几种感器的电镜扫描观察

Morphological Characteristics of Several Sensilla of Nephotettix cincticeps

为进一步探索黑尾叶蝉的行为,以利用其行为调节防治黑尾叶蝉,采用扫描电镜对黑尾叶蝉雌雄成虫触角、复眼、单眼和前足跗节外部感器形态进行了观察和研究。结果表明,黑尾叶蝉雌雄成虫触角上存在毛形感器和鳞形感器共2种感器,复眼、单眼和前足跗节上存在毛形感器,雌雄成虫各部位感器的类型和分布无明显差异。同时,描述了各种感器的形态特征和着生规律,并对其主要生理功能进行了分析和讨论。

The morphology of antenna,compound eye,simple eye and protarsus of female and male Nephotettix cincticeps adults was observed under a scanning electron microscope to further study the behavior of Nephotettix cincticeps for controlling Nephotettix cincticeps by adjusting its behavior.The results showed that there were squamiformia sensilla and trichodea sensilla on the antenna of female and male Nephotettix cincticeps adults,there were trichodea sensilla on compound eye,simple eye and protarsus of female and male Nephotettix cincticeps adults,and there was no significant difference in senillum type and distribution of different parts of female and male Nephotettix cincticeps adults.The morphological characteristics,insertion regulation and main physiological function of different senilla of female and male Nephotettix cincticeps adults were analyzed and discussed in the paper at the same time.
