[For further information, see Yearbook, United States Department of Agriculture, 1908, pp. 314-317.] The locust borer {Cyllene rohinice, Fig. 489) is a whitifth, elongated, round-headed grub, which hatches from an egg deposited by a black-and yellow-striped long-horned beetle, found on the trees and on the flowers of goldenrod from August to October. The eggs are deposited in August and September in the outer bark on the trunks and branches, and the young larvae pass the winter in minute hibernating cells between the outer corky bark and the living bark. In the spring they bore through the inner bark and enter the wood. Their presence is indicated in May, June and July by the boring dust lodged in the bark and around the base of the infested trees. The young hibernating borers may be killed from November 1 to April 1 by spraying the infested trunks and branches with kerosene emulsion, one gallon to two gallons of water. The older borers, after they have entered the wood, may be destro3'ed in May to July by cutting out the worst infested trees and burning them or immersing them in streams or ponds. The cutting of locust for any other purpose, however, should be done between November 1 and April 1, so that the removal of the bark from the utilized part of the trunk and the burning of the tops will kill the young borers before they enter the wood. New plantations should be made where the locust is naturally free from general injury, and seed for the purpose should be from trees which show the least dam- age.
