Winter Quarters of the Spotted Cucumber Beetle and the Cowpea Curculio, and Results of Burning*

The spotted cucumber beetle, Diabrotica duodecimpunctata (F.), is a very common insect in the South where it is important as a pest of corn (the southern corn rootworm). The cowpea curculio, Chalcodermus aeneus Boh., attacks the pods of all varieties of cowpeas but is especially harmful in those used for table and canning. Projects on the biology and control of these insects conducted in central Georgia have included studies, for four consecutive winters, of the location of hibernating quarters. These hibernation studies on the two insects have been carried along together for the sake of convenience, although the projects are not related.
