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.
A new guide in the open-access Journal of Integrated Pest Management outlines the key strategies for managing the invasive fall armyworm in Africa.
On smallholder farms using Bt maize in Africa, the combination of reduced field size and multiple pests presents challenges to insecticide resistance management. A new report in the open-access Journal of Integrated Pest Management offers recommendations for best practices.
In the response to the fall armyworm's arrival in Africa and Asia, researchers have now identified parasitoid wasp species serving as natural enemies of the crop pest on both continents.
