Excerpt from Cooperative Economic Insect Report, Vol. 15: March 5, 1965 European corn borer was generally less abundant in the Midwest than during the 1963 season. Considerable increases were noted in portions of Kansas and Missouri, but decreases occurred in areas of Nebraska, South Dakota, North Dakota and Minnesota. Adverse weather conditions during egg laying and early develop ment of first - generation borers affected populations in some States. (status of the European corn borer in 1964 appeared in ceir armyworm larval infestations were the heaviest in many years in Michigan and the pest caused severe damage to corn in Wisconsin. Outbreaks and problems of this noctuid were reported from several Eastern and Midwestern States, as were outbreaks of fall armyworm in Southern, Eastern and some Midwestern areas. Damage by this latter pest was reported from Texas to Illinois and Wisconsin and from several areas along the Atlantic coast. 'southwestern corn borer was reported from 4 new counties in Illinois, 11 new counties in Alabama and one new county in Missouri during the 1964 season. The number of girdled stalks in Missouri was down slightly from 1963, but infestations were heavier in Arkansas than they were the previous year. Corn rootworms continued to be a problem in several areas, with western corn rootworm the primary concern on corn in Kansas during 1964, and the dominant species in Nebraska. Western corn rootworm extended its range in South Dakota and caused considerable crop damage there, and infestations were found over a wide area in southern Minnesota, where problems are predicted for the 1965 season. This pest was found for the first time south of the Missouri River in the State of Missouri during the 1964 season. Northern corn rootworm fed on corn silks and pollen in Wisconsin, Illinois and Missouri, and caused severe silk damage and prevented ear development in many late - planted fields in Indiana, as well as causing significant losses in southern Michigan. Rice weevil was as heavy in corn at harvest time in Louisiana as at any time in several years. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
