In Pennsylvania, a team of Penn State entomologists have demonstrated that biopesticides — naturally occurring microorganisms — might provide an answer to this pest problem. According to Nina Jenkins, senior research associate in entomology, preliminary bioassays on the effects of Beauveria bassiana — a natural fungus that causes disease in insects — on bedbug control have been performed, and the results are encouraging. The speed of mortality with B. bassiana is as fast as Jenkins has seen in any application. Next, the researchers will test the effectiveness of brief exposure times and look at entire populations where natural harborages are established. Then they will begin field work.
