Abstract:Cutting is an important measure in maintaining alfalfa pasture. Choice of times and intervals for cutting directly affect the insect community composition and dynamics. The seasonal dynamics of insect communities on alfalfa pasture were investigated with biodiversity measures including species richness (S), unit numbers (N), Shannon‘s Index (H′), and evenness (E). The results showed that, in terms of species richness of the community, cutting influenced some rare species of insect pests rather than dominati...
