摘　　要：在江汉平原荆州郊区露地蔬菜田，应用佳多牌频振式杀虫灯对蔬菜昆虫进行了2a诱杀试验，以明确蔬菜田诱杀的昆虫群落的结构及多样性情况。结果表明：频振灯诱杀的类群较多，在不同年份之间波动差异不大，在同一年份不同月份之间波动变化较大。丰富度在高峰时约为50余种，但是其中鞘翅目和鳞翅目在其中所占比例较大，多样性在2．O～4．0之间波动，优势集中性指数在0．05～0．50之间波动，均匀性指数在0．3～0．8之间波动。根据诱捕结果判断害虫发生高峰时间，可以为害虫的监测与防治提供帮助。Trap effect of Jiaduo trapping lamp in vegetable field in Jianghan plain were studied for two years. The results showed that the insects lured by the lamp were mainly Lepidopteran and Coleopteran insect. There was no significantly difference between the number trapped in the two years, but there was significantly difference among the months. The peak of species richness was nearly 50, diversity index was between 2. 0 to 4. 0, diversity index varied from 0. 3 to 0. 8, while the dominant concentration index of insects varied from 0. 05 to 0. 50. It was helpful to detect and prevent insect pests according to the peak time of pest trapping results.
