Excerpt from LeafletIntensive methods of insect control, which may not be practical under forest conditions because of their excessive cost, may be economical when applied to certain shade and ornamental trees of high aesthetic value. In order to understand the methods used in combatting, the insects it is necessary to know that they are divided according to their feeding habits into two great groups: chewing insects and sucking in sects. The method of treatment for control will depend upon the type of pest involved.The chewing insects have sharp mandibles which correspond to' our teeth. These mandibles work in and out and are adapted for chewing foliage, or mining the hardest wood as the requirements of the species may demand. In the case of these chewing insects, it may be the larva form which does the damage, as is the case with most of our moths-and butter¿ies (lepidoptera), or it may be the adult form which causes the injury, or both the larva and adult forms may be injurious, as is the case with the Japanese beetle.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
