The results showed that the insects trapped by the lamp were mainly Lepidoptcra and Coleoptera insects. There was no significant difference between the trapped numbers in the two years, but there were significant difference among the months. The peak of species richness was nearly 50 ; the diversity index was from 2.0 to 4.0, and the even- ness index varied from 0. 3 to O. 8, while the dominant concentration index of insects varied from 0.05 to 0. 50. It was helpful to detect and prevent insect pests ac- cording to their peak occurrence time inferred by trapping results.展开更多
