Abstract
When spring wheat cultivars were evaluated for yield in field tests made in 1969 and 1970 in areas of Michigan infested with Oulema melanopus (L.), a combination of seed treatment with carbofuran and foliar-spray treatment with endosulfan reduced beetle damage. Untreated plots had highly significant losses in yield whether yield was expressed as bushels per acre, the weight of 1000 kernels, the number of kernels per head, or the straw length. Thus, the spring-wheat-producing areas of the United States could expect a 25% loss in yield if this insect should become a serious pest in these regions.Keywords
