(Coenorrhinus pauxillus), a beetle of the family Curculionidae. The body is 2-3 mm long and green-blue with a metallic sheen. The snout beetle is found in Europe, southern Iran, European Russia, and the Caucasus. It damages fruit crops, including apples, pears, and plums, and is especially harmful in the forest-steppe regions. The beetles eat leaf buds, flower buds, and flowers. The larvae eat out passages in the veins and mines in the flesh of the leaves, causing them to fall when there are many larvae. Control measures include destruction of the pupae by spraying the soil under the trees in autumn, destroying the larvae by gathering and burning fallen leaves, and destroying beetles by treating trees with insecticides.
