Behavioral responses of elm bark beetles to baited and unbaited elms killed by cacodylic acid

Diseased elms, treated with various doses of cacodylic acid in northwest England, became attractive to elm bark beetles (Coleoptera: Scolytidae). This attraction seemed to be independent of pheromone baits. However attractive the trees became, they were unsuitable to the beetles as breeding sites since significantly more beetles visited the trees than were stimulated to penetrate and attempt to breed. It seems as if colonization of trap trees by the bark saprophytePhomopsis oblonga following cacodylic acid treatment made the trees unsuitable to beetles for breeding.
