摘要
根据烟粉虱Bemisia tabaci(Gennadius)1龄后期若虫固定取食后不再移动的现象,采用数码相机拍照,然后打印输出到A4纸上的方法,使得对烟粉虱若虫位置的标定简单易行。利用该方法,观察烟粉虱发育过程中若虫的形态变化,分析烟粉虱若虫龄期和身体尺寸的关系,结果表明,可以根据若虫大小,结合形态特征识别烟粉虱若虫的龄期。
It had been observed that the nymphs of the whitefly, Bemisia tabaci （Gennadius）, would not move after feeding in the late first instar. A method for marking the locations of the nymphs on host leaf was developed based on the printed photos on A4 paper taken with digital camera. Furthermore, the morphological change of nymphs was observed, and the relationship between the body size and the instars of B. tabaci nymphs was analyzed with this method. The results indicated that nymphs of different instars could be distinguished according to their body size and morphology.
