5406057 walnut twig beetle Pityophthorus juglandis Adult beetles that emerged from two 18 inch black walnut logs. Walnut twig beetles continued to reinfest until cambium was completely consumed. A total of 23,040 beetles were recovered, approximately 36 per square inch of cambium area.
5406062 walnut twig beetle Pityophthorus juglandis Entry wounds made in trunk. A small amount of weeping can sometimes be observed when beetles enter trunks.
