Book excerpt: Excerpt from Control of the Locust Borer The locust borer severely damages its host trees by making large tunnels in the sapwood and heartwood which render the wood use less for-posts or construction work and may often cause the tree to break and fall. Black locust is being extensively planted for soil-binding purposes on eroded lands, and this circular deals largely with the protection of these young plantations. The adult is long-horned beetle, about three-fourths of an inch in length, which lays its eggs in rough crevices of the bark or around wounds. The insect hibernates as a young larva in the inner bark of the tree and bores into the wood the following summer. Recent investigations, covering a. 7 -year period, carried on at Columbus, Ohio, have shown that a very close relationship appears to exist between damage by the locust borer and tree vigor. The more vigorous the tree the less is the borer damage; Factors that reduce the vigor of the tree tend to increase its susceptibility to borer injury. Important among these factors are drought, fire, and graz ing of livestock; _on the other hand, factors that stimulate growth rate tend to reduce the susceptibility of a tree to borer injury. Certain silvicultural methods, designed to improve growing condi tions, have demonstrated considerable promise in borer control. These include clear-cutting, thinning, mulching, and the use of mixed plantings. Of these, clear-cutting appears useful in slowly growing stands where cutting of the trees is followed very rapid growth in the sprouts which develop from the stumps. Thinning is applicable in moderately to rapidly growing stands, where the more slowly growing and highly susceptible understory trees are removed to re duce the borer population and to make conditions for growth more favorable in the residual stand by reducing competition for light, moisture, and soil nutrients. Mixed planting has promise in the establishment of new plantations on soils which will support other broadleaved tree species. Mulching with hardwood leaves, because of the cost, is limited to trees of high value. Mulching effects may be obtained at verv low cost, however, by interplanting black in existing open-park woods. The use of superior varieties of black locust appears to offer some promise of control. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
