The fat lower legs that dangle below flying wasps in the family Gasteruptiidae turn out to be filled with insect fat body, and they may play key roles in flight dynamics, detecting vibrations from prey, and even detoxification.
A parasitoid wasp from Asia offers promise for biological control of the brown marmorated stink bug in North America, but new research suggests that monitoring efforts using primarily ground-level traps may be looking in the wrong place.
Fighting Nature With Nature: Scientists Mobilize Biological Control Against Devastating Fall Armyworm
Researchers at Virginia Tech's Feed the Future Innovation Lab for Integrated Pest Management are looking to biological control for the fall armyworm, with plans to deploy native, mass-reared parasitoid wasps in Kenya, Tanzania, and Ethiopia in the coming year.
To manage pest infestations in greenhouses, banker plants draw in different insect species that don’t feed on the main crop but do serve as hosts for predator insects that will also attack the pest on the main crop—a useful (and green) tool for integrated pest management.
