Predatory Coccinellidae in Cropped and Succesional Habitats

The seasonalabundance of 10 species of ladybird beetles was monitored over 13 years to quantify changes in species assemblages of predatory insects as a function of row crop ecosystem management in annual and perennial field crops, as well as secondary succesion vegetation. Crops included corn, soybean, and wheat rotations as well as forage crops such as alfalfa, and agroforestry.
