Abstract
THE classification of insects by the damage they cause is not, perhaps, scientific, but is of great practical use to the gardener. Mr. G. Fox Wilson outlines such a classification of fruit tree pests (J. Roy. Hort. Soc., December 1935). Feeding habits of different types of fruit tree pests are discussed, and the structure of the mouth parts is considered in relation to their effects on the plant. The work of Nierenstein on gall formation is passed under review, and the effects of ‘honeydew’ are discussed. Very little new knowledge is contained in the paper; its main value lies in the convenience of its outlook from a horticultural point of view.
