A research team at Virginia Tech has identified three genes that help the bedbug

population resist pesticides. They have found bedbugs produce enzymes that can

bind to, deactivate and break down two of the most common pyrethroid pesticides.

Bedbugs also have a mutation in their sodium channel gene that aids their resistance to pyrethroid pesticides.

In the past decade, there has been a resurgence in the U.S. bedbug population and the bugs have developed this resistance. Entomologist Zach Adelman stated, “Different bedbug populations within the U.S. and throughout the world may differ in their levels of resistance and resistance strategies, so there is the need for continuous surveillance.”

Studies in pesticide resistance will help researchers develop better pesticides or other ways to control the bedbug population.
