Suitability of Elm Firewood to Bark Beetle Attack Stored Under Polyethylene Sheeting    (View PDF)

Pavel Svihra

Abstract: Six mil clear polyethylene sheeting, resistant to ultraviolet rays, was used as a seal to prevent the colonization of elm firewood by Scolytus multistrlatus, the vector of the Dutch elm disease fungus. In California, elm firewood sealed and aged under polyethylene sheeting for up to three months maintained a similar attractiveness to the bark beetle as did freshly cut firewood, after wood was exposed. When wood was aged for four to six months under sheeting and then exposed, the beetles, not only delayed their attacks but also colonized fewer bolts, and in lower densities, than on freshly cut bolts. When firewood was sealed and aged for seven or more months under sheeting before exposure, it was no longer attractive to S. multistriatus.
