The presence of this insect is usually indicated by " saw- dust" or diseased bark and beneath the latter, legless, white, round headed borers are found. The brown beetles, striped with white, about 1 inch long, occur from June to August. Two or three years are required to complete the life cycle. Treatment: protect base of tree with wire netting. Dig out the young borers in the fall. Cut and burn badly infested trees. 10 Pear midge (Diplosis py- r i Y o r a). The dwarfed, deformed, infested fruit drops early, and within occur thick bodied, pale yellow mag- gots. The parent midge appears about the time the trees are in bloom and deposits her eggs. The young grow rapidly and cause a distortion of the fruit, which usu- ally cracks with the first good rain about June 1. The larvae then enter the ground and pupate. Treatment: destroy infested fruit. 11 Peach bark borer ( S c o 1 y t u s Fio. 10 Burrows of peach bark , , rr^-, ^ -, n ^ i -, borer In a young apple tree r U g U 1 0 S U S ) . The bark Of affected.
