The encyclopedia of practical horticulture; a reference system of commercial horticulture, covering the practical and scientific phases of horticulture, with special reference to fruits and vegetables;. Gardening; Fruit-culture; Vegetable gardening. PLUM PESTS 1699 through the side of the fruit, making a rather large, circular hole. This insect is the plum gouger, Coccotorus prunicida. It is slightly larger than the plum cur- culio, lacks the warts or humps of the latter on the wing covers, and has many- short, whitish hairs which give it a prui- nose or light-colored, dusty appearance. Until it escapes from the fruit, there is generally no indication of its presence, except possibly a small scar from which the gum exudes. Occasionally a mal- formed fruit indicates its presence. The pupal stage is passed in the pit and the fruit seldom falls until the beetle is just ready to escape. By far the most effect- ive remedy is to pick and destroy the in- fested fruit as fast as it falls, because spring spraying is not very successful. Hogs running in the plum orchard do the work very well, but where these animals are not available, or are objectionable, pick up the fruit by hand and feed to hogs, or burn or bury fully two feet deep. The beetle hibernates over winter. This insect is quite injurious in the states fur- ther west, but so far as known, it causes little or no damage in Ohio. H. O. GOSSARD, Wooster, Ohio. Plum Web Worm Lyda ruflpes Marlatt The gregarious false-caterpillars of a saw fly which web together the leaves of small branches and strip them of all green cellular portions in a very similar manner to the larvae of the cherry-tree tortrix. Seems to be distributed in Minnesota and the Dakotas northward into Mani- toba. Plum trees in Manitoba are report- ed to have been defoliated one year by them. The eggs are deposited in close masses along the under side of the mid-rib of the leaf, the long axis of the eggs lying par- allel with the mid-rib. The younger le
