Excerpt from Report on the Gipsy Moth Work in New EnglandIn carrying on measures for the control of any insect pest it is necessary to conduct many experirnents in order to determine the means which are most feasible for reducing the damage. For more than 20 years experiments have been carried on more or less con tinuously by the State of Massachusetts and other States to which the gipsy moth has spread, as well as by the Bureau of Entomology, for the purpose of perfecting field measures for holding the insect in check, and from time to time improvements have been made which have reduced the cost of handling infested areas. Spraying ma chinery has been developed so that at the present time it is entirely practical to treat large areas at a moderate cost. The banding of trees with tanglefoot has largely replaced the use of burlap bands and reduced the cost of this method of treatment. In fact, so much work has been done along these lines that the best methods of treat ment are well understood and practiced in the areas where the gipsy moth is prevalent. Minor improvements are being made from time to time but in general satisfactory methods of hand suppression have been adopted.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
