Excerpt from The Biological Control of Mealybugs Attacking CitrusGreat difficulty has always been experienced in the attempt to control these insects on citrus trees. The ordinary methods of control for scale insects, fi.e., Spraying and fumigation, have uniformly failed to bring relief, even when applied at much greater strength than has been necessary to handle satisfactorily such pests as the black, red, and purple scales. Much experimental work has been carried out. By the United States Department of Agriculture, the Citrus Experiment Station, and the County Agricultural Commissioners, in the hope of discovering improved methods or more satisfactory insecticides for the purpose, but the resistance of these insects has been so great that it has seemed practically impossible to destroy them without seriously damaging the tree and fruit.The situation led entomologists to give consideration to radically different methods for the suppression of mealybugs, and out of this has come the biological method, the discussion of which is the pri mary object of this bulletin.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
