Predatory bugs can save cornfields
Date:11/30/2010

This press release is available in Spanish.

One of the worst pests of corn in the world, the corn rootworm, may owe its worldwide success partly to its larvae's nasty, sticky blood.

U.S. Department of Agriculture (USDA) entomologist Jonathan G. Lundgren and his colleagues discovered this recently, working with CABI researchers in Delmont, Switzerland, and Hdmezővsrhely, Hungary. The discovery could lead to development of ways to overcome these defenses as part of sustainable, ecologically based pest management methods.

Lundgren works at the Agricultural Research Service (ARS) North Central Agricultural Research Laboratory in Brookings, S.D. ARS is USDA's principal intramural scientific research agency, and this research supports the USDA priority of promoting international food security. CABI is an international not-for-profit organization that researches natural ways of controlling pests, and they have been helping to lead the effort against corn rootworm's European invasion.

The experiments with CABI are the latest in Lundgren's research on corn rootworm predators. Although rootworms have been a major pest for 100 years, this is remarkably the first comprehensive research program on corn rootworm predators to be conducted.

In lab and field experiments in the United States and abroad, the rootworm larvae's sticky blood caused certain species of predators to quickly back off. The foul-tasting blood coagulated in the predators' mouths, temporarily gluing them shut. Predators repelled by the rootworm larvae's blood included ground beetles and ants.

Wolf spiders, on the other hand, had a hearty appetite for rootworms. When insects such as spiders suck fluids from prey rather than chewing their victims, they may be able to bypass the ability of the blood to stick and linger.
