Moths are small insects of the Lepidoptera family, with approximately 35,000 species. Agree, a lot. These small but harmful insects can be found almost everywhere: in the north and south. For you and me, they are pests that can cause colossal damage. The most damaging of all species, however, is the group that anyone who grows vegetables and fruits can encounter - gnawing scoops.
In the category of gnawing scoops, a considerable number of butterflies wake up at night and rush to the nearest garden. Bear, winter, potato butterfly ... Everyone has heard the names of these butterflies at least once. They can be found not only in the garden.
Gnawing scoops - varieties
Gnawing scoops are nocturnal insects, they always fly into the light, be it a phone screen or a lamp on the veranda. Acquaintance with the enemy Any butterfly from the Lepidoptera family is an insect that feeds on almost everything, and often its diet consists of a variety of plants.
They are different: large and small, gray, brown, even brown. In appearance, they are unremarkable. Their wings are narrow, patterned. The front wings are longer than the rear ones. This feature is typical for any type of scoop. Because of the peculiar pattern on the wings, they got their name. It is quite clear, consists of straight and winding lines. Also, rings and circles may be present there. The front wings are darker than the rear ones and have a grayish-brownish tint. But, in addition to the gray tint, there may be red or blue spots on the hind wings.
Nightgirls
This is also the name of this type of butterflies, they fly out to "hunt" in the evening or at night, which is clear from the name. It is practically impossible to see them during the day. During the daytime, they sleep, attached to the back of the plant leaf. That is why you should check the flower before picking it from the garden. Adult caterpillars live underground, feeding on roots and vegetables, nibbling them superficially.
Winter scoop
It lives almost everywhere. The only exceptions are the north and especially arid regions; however, some individuals can be found there as well. It can be found in many regions. She lives throughout the European part of the country, and people in the North Caucasus and in the Urals also suffer from her "raids". However, the geography of the spread of the parasite does not end there. It can be found in the Far East, in the south of Siberia. As you can see, this type of parasite butterfly is widespread in Russia and abroad. The wingspan of the insect is 35-50 mm. Their color can vary from shades of yellow to dark gray. As a rule, the color spectrum of the wings of this insect contains all shades of gray and brown. Dark lines cross them across. There are usually four of them.
Caterpillars are especially tenacious and can survive severe frosts in winter. They survive at a depth of 15–30 cm. As soon as the spring sun begins to warm the ground a little after a cold winter, the caterpillars move to the surface of the earth, where they build peculiar caves and pupate there. Pupae live underground for about a month, where they gain strength and grow.Their cover takes on a reddish-brown hue; at the end of the pupa there are two spines, about 20 mm long. For years, butterflies gather at the end of May and stay there almost until the end of July. The winter moth behaves most actively at night. ,
A cluster of butterflies can be detected by pheromone traps; in the absence of an opportunity to create such a trap, using molasses fermenting in a bowl. It must be installed about 20 cm above the ground. To do this, it is necessary to mix molasses and water in a container in proportions of 3: 1, add the same fermented yeast in an amount of 50 g / liter of water. As soon as the butterflies leave the cave shelters, they go to the nearest green area for reinforcements. There they spend several days, reinforced by immature sprouts and the first fruits. ,
However, their main goal is not to reduce hunger, but to find a cozy shelter for breeding a new generation. Any plant is perfect for this purpose. The butterfly of this species is very fruitful.
For those who actively look after their garden, a very crucial moment comes, which cannot be missed. It is necessary to disinfect and treat the sprouts with drugs in order to prevent a further "raid" on the garden of already ripe butterflies. If the moment is missed, then it will be too late. Getting rid of these parasites is not easy. Grown caterpillars crawl into the upper layers of the earth, closer to the surface, where they live, crawling out at night to feed.
The first generation begins its malicious activity in June. With the onset of warmth, until the beginning of autumn, the parasite years begins. Gnawing moths lay eggs on cultivated plants so that the larvae, just born, have something to eat, grow and gain strength. They apply to crops sown on the eve of winter, laying eggs in the soil where the grain was previously sown. Given the fact that the larvae can easily tolerate the cold, it is highly probable that all crops will be infected by the spring.
