In the vastness of our homeland, this species of Lepidoptera is not welcomed due to the fact that they destroy the crop. Cabbage is not in vain got its name, it affects cabbage leaves. Otherwise, the variety under discussion is called whites due to the peculiarities of the shade. In today's article, we will consider everything about these garden pests. We highlight the main aspects so that you make up your own opinion.
Description
- By cabbage we mean whitefish, which prefers to stay awake in the daytime. The front wings in terms of size characteristics are about 3 cm. Their wingspan ranges from 5.5 cm, which is quite a lot for these representatives of the family. Females are larger than males.
- By color, the whites are whitish, as the name implies. A yellowish tint may be present. Do not confuse this representative with others, believing that her wings are surrounded by black thin stripes. These are two completely different species of Lepidoptera. Specks of a brownish or black tone may be observed. They are located closer to the junction of the wings.
- In the lower part of the hind wings there are yellowish pigments. Other inclusions are observed in the middle section. If you touch the wings, they will lose in color. The spots will disappear, and the structure itself will become translucent or white. Pollen refers to small particles that fit snugly on the surface. In view of this feature, butterflies are considered to be a lepidoptera family.
- Insects have a developed sense of smell and the same vision. They can determine without error which plant is edible and which cannot be consumed. The eyes are large, occupy a decent section of the head. Insects also have long antennae with seals at the ends. They help to recognize plants.
- These representatives of the species on the wings have pollen, which serves for pollination of vegetation. However, this does not mean that there is only one benefit from insects, some bring damage to the crop. As for the differences in gender, females are slightly larger.
Habitat
- The species under discussion is quite common in North Africa. Representatives of the species are also found in eastern Europe. Not without distribution in Asian countries. Cabbage women love Japan for the climate there that suits them.
- Some individuals may inhabit the Arctic Circle to the north. Numerous studies have established that the butterflies of this family migrate. They are found in Panama, Chile, Peru.
- As for the locality, individuals prefer to be in garden areas, parks, gardens, on forest edges. They easily get along with other insects in the forest strip and the steppe.
Lifestyle
- By whitewash is meant an active type insect that can migrate from one locality to another in search of better conditions. The butterfly is active, usually from mid-spring to mid-autumn season. If normal conditions exist for the lepidoptera, then it will produce about three offspring per year.
- Lepidoptera do not fly at night, because they prefer to do this in daylight. They are active when it is warm outside, they do not like rain and try to be in shelter during heavy rains. The wind will also harm, shortening its lifespan.
- It is believed that lepidopteran individuals cause damage to the garden, namely the cabbage crop. This is partly true, they are voracious, and therefore absorb many plants. Moreover, the ability to pollination does not cover in any way.
Control measures
- If you start from the reference literature, which describes the growing technology of vegetable crops along and across, then in the corresponding section you can find information about pests, which are cabbage. If you do not fight them, then the crop will be damaged forever. And we are talking not only about cabbage, but also about other vegetable crops.
- The largest gluttony peak occurs at that time, while the cabbage is still a caterpillar. She absorbs seedlings. To understand that a pest is wound up in the garden, you need to consider the leaves. They are all in holes. Insect larvae also lead to diseases and death of plants, especially for radish with cabbage.
- Butterflies overlap cruciferous plants, so they are all at risk. A specific disease is caused by the excrement of the caterpillar. If the garden is teeming with pests, then they are cleaned by hands and destroyed. The same is done with eggs on the other side of the leaves.
- It is necessary to deal with cabbage valerian, or rather a solution based on it. It is enough to connect 50 ml. funds with 3 liters. water and sprinkle with this composition of the plant. While the heads of cabbage do not start, drugs like phytoerm are used.
Nutrition
- If you look at the photo of the butterfly or the individual itself, it is difficult to guess what and how it eats. Most gardeners claim that the insects presented prefer cabbage. Thus, they cause enormous damage to the crop.
- Separately, it is worth mentioning that such individuals do not only eat cabbage. Their diet also includes horseradish, rutabaga, capers, radish and canola. In some cases, the butterflies in question prefer nasturtium, mustard, and even garlic.
- Accordingly, those people who are engaged in agriculture, cabbage is a particular problem. The bottom line is that such insects penetrate the head of cabbage. Then the butterfly begins to eat leaves without stopping.
- The insect has a truly voracious appetite. During this, the crop can be completely destroyed. As for the conditions in the wild, the presented individuals prefer mother-and-stepmother, chamomile, alfalfa and dandelions when eating.
Breeding
- Female representatives of the species in question lay eggs that are painted yellow. Most often, individuals form a clutch in groups. The insect itself can already give offspring, on the 7th day after it has turned into a butterfly.
- In one clutch there may be about 200-300 potential future butterflies. In order for the offspring to be completely protected from weather conditions, the female attaches eggs to the back of the leaves of the plants. After a couple of weeks, you can already see the caterpillars being born. Larvae are somewhat similar to worms.
- Despite the fact that the young is called caterpillars, in appearance it looks more like larvae. Offspring even have a characteristic color. It is thanks to him that larvae are difficult to detect among foliage. Therefore, summer residents often encountering such pests say they have discovered cabbage worms.
- However, the larvae are highly viable. The caterpillar has 3 pairs of legs and a chitinous cover. In addition, she has oral appendages. In addition, for better engagement with the surface, the larva has additional legs, which originate from the abdomen.
- As soon as the caterpillar turns into a butterfly, such legs simply cease to play their role. When adult larvae are full enough, they leave cabbage heads. In this case, they change their place of residence. Caterpillars move to live on branches, trees and fences. At this time, they can grow up to 4 cm.
- However, in order for them to grow to such a size, you need to live about 40 days. Then the larvae look for a place for attachment. They begin to secrete a web, thanks to which they are attached. After some time, a pupa forms. Then a full-fledged butterfly with a white color appears.
- It takes several weeks to turn into a full-fledged butterfly. In addition, the individual molts several times at this time. This process can be called a complete transformation. Caterpillars mature best in warm climates. In this case, the process is fast enough.
In warm time, insects turn into butterflies mainly in the middle of summer. If the caterpillars managed to turn into pupae at the end of summer, they tolerate wintering in this state. Then in the warm spring full butterflies appear. Most often they settle in various buildings, shrubs and under the bark of trees.
