She lays her eggs on the bark of the tree near the ground, and the larvae when hatched eat inward, killing or injuring the tree. One remedy is to keep the adult from laying her eggs on the trees by banding them with tar paper, veneer wood or other mater- ial (Fig. 147). Another remedy is to dig out worms and kill them with a knife or wire. To do this it is well to remove the soil for several inches below the

One remedy is to keep the adult from laying her eggs on the trees by banding them with tar paper, veneer wood or other mater- ial (Fig. 147). Another remedy is to dig out worms and kill them with a knife or wire. To do this it is well to remove the soil for several inches below the surface. In a few days the larvae may be located by their borings. Para-dichloro-benzene spread on bare soil two inches away from trunks, in fall, and then covered with soil, will kill the bor- ers in 5 or 6 weeks. This is safe for trees 6 years old. Use one ounce per tree. (See Farmers' Bulletin 1246). Soil should be 60 de- grees F. or warmer. The plum curculio is the worst enemy of the fruit itself. This little beetle lays eggs on the surface of the fruit when it is about the size of the garden pea. The young, hatch and eat their way into the fruit at a wound made by the adult. The larva feeds on the flesh of the fruit, chiefly near the stone. This causes much fruit to fall. This should be picked up, as by pigs. Larvae soon crawl into the soil. Chickens and birds may catch some. Frequent tillage for five weeks after this will destroy many and prevent their second brood. Winter hiding places should be destroyed by plowing under rubbish and burning borders. As the adults lay their eggs cheifly in the morning twilight they.
