为了保证棉花丰产防治棉蚜,首先要了解棉蚜的发生规律。研究棉蚜的寄主植物是其中一个重要环节。因为棉蚜寄主很多,研究清楚后才可了解它的来踵去迹,才可筹划防治措施。 一般对于蚜虫寄主植物的记载,大都根据调查观察所得的植物和蚜虫加以种的形态特征上鉴定,即可认为这种植物是这种蚜虫的寄主。由于蚜虫迁移时有偶然栖止现象,同时蚜虫种的特征不是很明显和稳定的,就是有经验的蚜 In order to ensure the cotton yield control cotton aphid, we must first understand the occurrence of cotton aphid law. The study of host plants of cotton aphids is one of the important links. Because the cotton aphid host a lot of research to understand it after the heel to track, before planning control measures. Generally recorded for aphid host plants, mostly based on investigation of plant and aphids obtained from the morphological characteristics of the species identified, you can think of this plant is the aphid host.
