The fall armyworm's impact on maize earns plenty of attention, but it is in fact polyphagous. Sorghum, a key cereal crop in Africa, is also vulnerable to the pest's damage, and researchers are working on biocontrol and other integrated pest management methods in hopes of containing the fall armyworm's impact around the world.
A new study shows that growing a variety of crops in the same field increases local insect diversity and even improves the ratio of natural-enemy insects to pest insects.
The parasitic wasp Telenomus remus can be cheaper to raise on a commercial scale on the eggs of an alternate host, rather than those of the fall armyworm, the pest the wasp naturally parasitizes in the field
While a greenhouse structure affords growers pest control options that are not available for field crops, such as physical exclusion, it can also create challenges.
