Final Project Results

Six states evaluated aphid resistant lines, and found that the Rag1+Rag2 gene pyramid suppresses aphids the most, and insecticidal seed treatment did not result in yield gain. The project was completed and the results have been submitted for a peer-reviewed journal article.

Six states evaluated insecticidal seed treatment for aphid management. Data analysis is underway including an economic cost/benefit analysis.

Regional screening for aphid populations resistant to thiamethoxam insecticide established a field baseline value for future comparison, and found no substantial insecticide resistance to date.

Other studies indicate documenting that aphid population growth increases with increased soil nitrogen, but not with potassium; developing a regional aphid monitoring network which provides early-warning of higher than average aphid populations in Wisconsin and Michigan; and developing beta software for an automated aphid counting system that shows good accuracy in preliminary testing; ultimately this tool may help speed data collection and also scouting for management decisions.
