“ THE PLUM CURCULIO, Conotrachelus Nenuphar. BY WM. SAUNDERS, LONDON, ONT. The season when the “little Turk” begins his destructive work on our plum crop is at hand, and it behooves all growers of this fruit, henceforward for several weeks, to make a vigorous onslaught on this stealthy foe. Although the Plum Curculio has been so often described, and is so well-known to the majority of our readers; still we find many beginners in fruit growing who have not yet made its acquaintance, and for their benefit we insert the accompanying figure, and give a brief description of the insect. ”

“ Some insects occasionally use the ovipositor merely for defense. The curculio has an especially interesting method of laying her egg. First she digs a hole, in which she places the egg and pushes it well down. Then with her snout she makes a crescent-shaped cut in the skin of the plum, around the egg. This mark is shown in Fig. 154. As this peculiar cut is followed by a flow of gum, you will always be able to recognize the work of the curculio. Having finished with one plum, this industrious worker makes her way to other plums until her eggs are all laid. ”

“ No less than forty [132] species of insects may be enumerated as pests of the plum and many more can be counted as occasional parasites on one or another of the species. Of the formidable pests the plum curculio is probably the most troublesome. The plum curculio [178] (Conotrachelus nenuphar Herbst) is a rough, grayish snout-beetle somewhat less than a quarter of an inch in length, an insect so familiar to fruit-growers as hardly to need a description. The female beetle pierces the skin of the young plums and places an egg in the puncture. ”
