The efficiency of early spring cultivation and the peach tree borer paradichlorobenzene treatment in oriental fruit worm control is dependent upon the distribution of the surviving hibernating population on and about the tree. Examinations of ten trees in southern Indiana indicate that this distribution is extremely variable and subject to such factors as variety, ripening date, amount of rough bark on the tree, debris on the ground, and winter mortality. Elbertas were found to have 100 per cent of their hibernating larvae on the tree, Krummels averaged 85.6 per cent, Fleener Clings 20 per cent, and White Heath Clings 18.6 per cent. Small bits of weed stems held more hibernating larvae than anything else under the trees. In 1929–1930 less than one per cent of the larvae hibernating above the snow line survived parasitism and low temperatures. Cultivation and the paradichlorobenzene treatment under such climatic conditions should be effective as partial oriental fruit worm controls. Under normal Indiana conditions, however, they appear useless when applied to early ripening varieties or to any variety when much of the trunk is covered with rough bark.
