4. Winter moth - northern locust

The winter moth (Agrotis segetum) is a particularly dangerous pest. The unremarkable appearance and modest size of the scoop are deceiving. The length of the body does not exceed 3-5 cm. The color of the wings of the scoop is monotonous-gray or yellowish-brown, on which separate spots and transverse dark and light stripes stand out. Dimorphism of females and males of the scoop: females have gray-dirty hind wings, males - white. Moths are active at dusk, feeding mainly at night.

Winter scoop hazard level

Under optimal environmental conditions, one female moth lays from 600 to 2240 eggs, of which the yield of caterpillars is up to 95-98%. In 20-25 minutes after emerging from the pupa, young moths are ready for flight and feeding.

Types of affected crops

Winter moth caterpillars damage more than 140 plant species of 36 families. They are divided into leaf-gnawing, intra-stem and gnawing, which destroy the root system of plants. One scoop destroys 10-20 sugar beet roots per day.

The scoop on the root plagues corn, tobacco, millet, cotton, by summer it switches to vegetable and industrial crops, including pumpkin, zucchini, peas, potatoes, and in the fall it populates winter and winter crops. From weeds, moths prefer to settle and feed on the roots of plantain, sow thistle, bindweed.

Signs of damage to vegetation by a winter moth

The moth caterpillars damage the stems at the soil level and practically eat away the base of the stems of young plants, potato tubers and root crops, leaving characteristic voids in which they sometimes settle. The scoops eat the soft part of the foliage, leaving only streaks. You should pay attention to the general wilting of a large number of plants in large areas literally within a day.
