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

Seongak-san, South Korea, were investigated from May to September 2013 using traps in order to collect basic data for distributional monitoring of species in a forest ecosystem. A total of 2698 individuals of 309 moth species of 18 families were collected in bucket-light traps, along with 196 individuals of 26 ground-beetle species and 11,276 individuals of 14 ant species in pit-fall traps. The insect community at each site was analyzed using analysisof variance and non-metric multidimensional scaling （NMS）. The ground-beetle and ant abundances varied with elevation. The NMS showed distinct clusters of moths between the ground-beetle and ant distributions with ele- vation and month. The community-level responses of these insect groups to those gradients were analyzed.展开更多
