| Abstract: | The number of the major nisect pests and their predators in soybean fields were investigated in southwest cotton areas of Shandong Province, China in 1997.Based on the investigated results, the niche breadth of species and the niche overlap indices among the species were studied. The competitive relationship among the major insect pests and the relationship between Helicoverpa armigera (Hubner) and their predators were analyzed. |
