Popis:	Peach bark beetles, Phloeotribus liminaris (Harris), made abortive attacks on healthy black cherry, Prunus serotina Ehrh., trees. The beetle attacks caused five types of gum spots in the wood and a gummy exudate on the bark. The most extensive and common types of gum spot were single and multiple rows of interray gum spots that encircled the lower 3 m of the tree. Three to four attacks per 6.5 cm² of bark surface caused enough gum flow to produce a continuous ring of gum spot in the wood.
