The Dangerous Colorado Beetle

The main food of the insect is potato tops, one female lays more than 600 eggs, in a month a new mature (capable of laying) progeny leaves from them. Under favorable conditions, colonies of parasites can grow rapidly. If nothing is done, nothing will be left of the green mass of potatoes, the tubers will not grow, and the beetle will switch to pumpkins, tomatoes, zucchini, watermelons, eggplants.

On a note!

The pest does not tolerate frosty, snowless winters, so it is more common in the south and in the middle lane, in the north the Colorado potato beetle does little harm.

The larvae overwinter in the soil, awaken en masse during periods of potato sprouting and budding, it is during this time that the leaves must be carefully inspected and started to fight. When the Colorado is full, he hides in the ground, so some methods of struggle may not give 100% of the result.
