Crops engineered to produce insecticidal proteins from the bacteria Bacillus thuringiensis (Bt) have had many noteworthy successes in the past 25 years, but resistance to Bt crops has evolved in numerous instances, as well. A new research review examines global patterns of resistance to Bt crops and outlines strategies for maximizing sustainability of this important tool for pest management.
A survey of corn farmers in Iowa shows which insect pests are of most concern and that most are not seeing failures in management methods such as Bt crops. But they do look to IPM and extension agents for guidance in managing insecticide resistance.
Researchers at Purdue University are developing new ways to apply spectroscopy in service of greater food security. By analyzing light reflected by plants, they can detect compounds the plants produce soon after they face an insect pest attack or other stressor.
Should growers that use Bt crops plant a separate nearby refuge field of non-insecticidal crops, or use a blended mixture of seeds that produce both in the same field?
For today’s post, we’ve got two more videos that were recently submitted to the 2013 ESA YouTube Your Entomology contest. The first one explains what host plant resistance is and […]
