The spring migratory flight of black cutworm moths remained impressive across Illinois and the Corn Belt through mid-April according to University of Illinois Professor of Entomology and Crop Sciences Extension Coordinator Mike Gray. Dale Baird, University of Illinois Extension, reported capturing 23 moths in his pheromone trap over a two-day period (April 14-15) in northern Illinois (Lee County), well above the intense capture threshold of nine or more moths over a one- to two-day time frame....More
Starting in 2009, the Department of Entomology at Iowa State University received reports of severe corn rootworm injury in Bt corn in Iowa. In all cases, western corn rootworm was the predominant rootworm species in these fields....More
Isolated findings of resistant rootworms in Iowa emphasize that planting a refuge is more critical than ever for maintaining the durability of Bt corn, says Christian Krupke, a Purdue Extension entomologist....More
In the mad rush to finish up what has been a challenging corn planting season, speed often takes priority over attention to detail, says Robert Bellm, University of Illinois Extension crop systems educator....More
Reports of late planting, flooding and saturated soils are inundating news sources right now, and corn growers need to take them seriously.
