Agr. 645 646 INSECT PESTS OF FARM, GARDEN AND ORCHARD exudes from the crowns of trees injured by them. The injuryis done by the larvse feeding on the soft inner bark of the crownof the root, the adjacent roots and the base of the trunk. Oftenthe larvse will completely girdle a tree and where a tree is infestedby several borers, the foliage turns yellow and if not treated willsoon die. Such a tree is much more susceptible to the attacksof bark beetles and diseases. Probably as many peach trees. Fig. 498.—Peach borer moths (Sanninoidea exitiosa Say)—natural upper one and the one at right are females, the other two males.(After Slingerland.) are lost from the work of borers as from any other one pest, withthe possible exception of the San Jose scale. The adults are clear-winged moths which fly during the dayand might be readily mistaken for wasps. The females are adeep steel-blue with a l)road orange band across the al) fore-wings arc opaque, covered by the Ijluish scales, andexpand about 1{ inches, while the hind-wings are transparentexcept the dark margin. The males are smaller, with the wings INSECTS INJURIOUS TO STONE FRUITS 647 clear except the margins and a line across the fore-wings, andthe abdomen is marked with three or four narrow yellow stripes.
