Weevil control begins in early spring and continues throughout the season. Most of the measures are classified as agrotechnical, they are timed to certain phases of pest development. There are also permitted insecticides that are used against various vine weevils.
Trapping belts
In early spring, before bud break, fasten trapping belts to tree trunks at a height of 30-50 cm. Belts can be dry, sticky, impregnated with insecticides. Trapping belts are an obstacle in the way of insects rising from wintering places to tree branches. Regularly inspect traps, destroy insects, burn paper traps.

A little later, during the swelling of the buds, when the apple flower beetle and other weevils are naturally on the tree, they can simply be shaken off. It is important to carry out the operation at a temperature below 10 ° C, when the beetles are inactive. In warm weather, they quickly scatter. Spread a thick bedding under the tree and tap sharply, but not hard, on the branches with a stick wrapped in burlap. So you do not damage the bark, and the beetles, who sensed danger, pretend to be dead and fall down. Shake off the flower beetle and other weevils at least 2-4 times over several days. Throw the fallen beetles into a bucket of water with the addition of kerosene or insecticide.

This radical method is used at a strictly defined time. Against the UK apple blossom beetle, spray the trees between bud break and bud emergence. Against the cherry weevil, treat immediately after flowering and again after 10 days. Use all insecticides strictly according to the instructions, without exceeding the dose, observing safety precautions.
