The article reports a study on preventing the spread of deadly beetles in oak and tanoak in western U.S. using permethrin. Researchers at the University of California in Berkeley, California collected samples from heavily infested trees, one half of each was surface-treated with the chemical. It was found that in the permethrin treated samples, neither beetle species was able to complete normal development. Though the researchers were not clear on how the emergence was prevented, the reduction was worth the effort to reduce the overall population. INSETS: COLOR CODED;SLIDING SCALE.
