The first comprehensive genetic study of bedbugs, the irritating pests that have enjoyed a world-wide resurgence in recent years, indicates they are quickly evolving to withstand the pesticides used to combat them.

The new findings from entomologists at Ohio State University, reported Wednesday online in PLoS One, show that bedbugs may have boosted their natural defenses by generating higher levels of enzymes that can cleanse them of poisons.

In New York City, bedbugs now are 250 times more resistant to the standard pesticide than bedbugs in Florida, due to changes in a gene controlling the resilience of the nerve cells targeted by the insecticide, researchers at the University of Massachusetts in Amherst recently reported.
