As fall armyworm continues to threaten food security in Africa, the use of Bt maize offers significant potential to manage the pest. But it will be critical to manage resistance via multi-toxin crop varieties and appropriate use of refuge planting—all in forms accessible to the smallholder farmers that grow nearly all of Africa’s maize.
Collaboration and a combination of transgenic cotton and sterile insect releases helped to eradicate the invasive pink bollworm.
A new article in the Journal of Economic Entomology examines varying levels of resistance to Bt toxins developed by the pink bollworm in the United States, China, and India over the last 20 years, illustrating the importance of incorporating refuge crops in Bt systems.
By Richard Levine One hundred years ago this month, an entomologist at the Washington Agricultural Experiment Station named A. L. Melander published an article in the Journal of Economic Entomology […]
