摘要
本文利用生物测试法,观测了异色瓢虫显现变种对不同寄主上的不同蚜虫的定向和选择行为。结果表明帖梗海棠、毛白杨、柳树在正常的生长状况下,不会产生引诱异色瓢虫的植物挥发性物质,在这些植物受到蚜虫危害以后,会释放出引诱异色瓢虫的植物挥发性物质,而紫藤在正常的生长状况下和蚜虫危害后,都会产生排斥异色瓢虫的化学物质。
The location and selectivety of Harmonia axyridis to different preys were investigated with Y olfactorneter. The result showed that Chaenome speciosa、Populus tomentosa、Sslix matsu-dana did not produce plant volatiles for attracting Harmonia axyridis. After these plants were injured by different aphids, plant volatiles were released to attract Harmonia axyridis. Wistaria sinen-sis released plant volatiles to repel Harmonia axyridis in any conditions.
