摘要:
研究了龟纹瓢虫在棉花上对不同密度、不同空间分布、不同来源棉蚜的搜索与捕食行为.结果表明,龟纹瓢虫对棉蚜的搜索活动随棉蚜密度增加而下降;当棉花上有充足的棉蚜时,瓢虫主要搜索和捕食棉花上部的棉蚜,很少捕食棉花中部的棉蚜,极少捕食下部的棉蚜;瓢虫对棉花不同部位上分布的2种不同来源的棉蚜捕食量没有差异;但当棉花上部主要为美9101棉花棉蚜时,瓢虫的搜索活动明显下降.龟纹瓢虫的捕食行为与蚜虫密度和空间分布密切相关。
摘要(英文):
The study showed that the searching activity of P. japonica on cotton aphid Aphis gossypii decreased gradually with decreasing aphid density. When enough A. gossypii existed, P. japonica had a preferential searching and preying activity on the top of cotton plant. There was no significant difference in the preying activity of P. japonica at different positions of cotton plant, while the searching activity of the ladybird beetle was significantly lower on cotton M9101 than on cotton Zhongmian 13. The preying behavior of P. japonica was sign...
