Insect remains are better 'suited' for fight against pests

Nematodes offer considerable potential as insecticidal products. However, a number of problems have prevented widespread use and acceptance of nematode-based insecticides.  One problem has been cost, which is often higher than conventional treatments. This is, in part, due to the need to grow nematodes inside of insect hosts, then extract them from the dead bodies of the hosts.


A more effective way to apply the nematodes may be in the offing. USDA-ARS scientists have developed a starch and clay coating that can be applied to the host cadavers to preserve the nematodes inside. Then, the cadavers themselves can be applied. In the outside environment, the coatings decompose, releasing the nematodes.
