Presented at the All Scientist Meeting (1999-07-20 to 1999-07-21 )
Research conducted at the Long Term Ecological Research Program for agricultural ecology and the Living Field Laboratory (both at the Kellogg Biological Station, MI) has resulted in the recommendation of using corn-soybean-wheat rotation integrated with the use of cover crops. These practices provide a more efficient use of carbon and nitrogen with additional environmental benefits aimed to minimize soil erosion and nitrogen leaching. Studies conducted with similar management practices in other crops systems have shown an important impact in the population dynamics of both pest and beneficial natural enemies. The experimental layout of the KBS LTER represents a unique opportunity to study the response of major groups of predators to a combination of habitat/management under the conditions of Michigan landscape. The objective of this work is to evaluate patterns of response of major predator groups to the management practices used for field crops in Michigan.
