Results of the 2013 corn earworm survey of field corn
Attached (click “More”) are the results of Dr. Herbert’s 2013 corn earworm survey of field corn in Virginia. In general, numbers of ears infested with earworm larvae were lower than in previous years. Hopefully this means fewer moths that emerge, leave this nursery crop, and lay eggs in soybean, cotton, peanut, etc. Our network of black light traps will help you determine moth flight activity in your area. It is also vital to scout your crops and use appropriate thresholds for eggs or larvae. For soybean, please use the Corn Earworm Economic Threshold Calculator found at http://webipm.ento.vt.edu/cew/ For cotton you should use the appropriate thresholds (conventional or genetically-protected) found in the 2013 Virginia Cooperative Extension Field Crops Pest Management Guide (beginning on page 4-108 found at http://pubs.ext.vt.edu/456/456-016/Section_4_Insects-11.pdf). Other insect chapters (soybean, peanut, sorghum, etc.) of the Field Crops Pest Management Guide, with appropriate thresholds, can be found at http://pubs.ext.vt.edu/456/456-016/456-016.html Additional information: cew-survey-results-2013-pdf
