Why does a caterpillar eat pepper
When holes appear on almost ripened fruits or only veins remain from the leaves, a caterpillar in the pepper appears in the garden or in the greenhouse. You need to get rid of it as soon as possible, until the plants have received severe damage.
Caterpillars eat pepper
Why does the caterpillar appear
Often a moth-like butterfly flies on the beds — it's a scoop. She lives about 3 weeks, but during this time she manages to lay eggs and thereby do a lot of harm to summer residents and farmers.
The butterfly immediately selects the plants on which the caterpillars will live and lays eggs on their leaves. Egg laying occurs before or after rain. In dry weather, the eggs dry.
The presence of a pest can not always be seen, especially if it hides during the day. Holes on the leaves, wilting of the plant, damage to the stem at the root, holes in the fruit - these are signs that the caterpillar eats domestic pepper.
More often, you can observe the caterpillars on the pepper in the greenhouse than in the open ground. This is due to the fact that they do not tolerate drought and the sun very well. In the greenhouse, sunlight is limited and high humidity - ideal conditions for reproduction.
Caterpillars first live on weeds and on grasses. When they lack nutrition, they crawl to other crops. Pests are able to travel long distances, so they can crawl from another area. Winter scoop eats 150 different cultures, and gamma scoop about 390.
There are many varieties of these insects, but in the suburban areas there are two:
- Winter scoop.
- Gamma scoop.
Winter scoop is a biting species of insects. Pests parasitize from below the leaves. It is this species that gnaws holes in the fruits, eats roots and stems.
The caterpillar has a grayish color. The first days she lives on a plant, and then hides in the ground, and crawls out only at night. Therefore, it is difficult to detect and even more difficult to get rid of.
Gamma scoop - leaf-eating pest. One butterfly lays about 1, 500 future larvae. Descendants of them are born in a week. The caterpillar eats green parts, gnaws the pulp of vegetables. Lives on the stems of various cultures and in the sinuses. They differ from winter scoops in color - they are light green or green with small gray dots. For the winter they hide in the soil.
Caterpillars appear twice during the season
In order to be prepared for pests and take measures to protect peppers in time, you need to know when to wait. Butterflies and caterpillars appear in two waves:
- In the spring, in April-May.
- In the summer, from the second half of July until the end of September.
Pupae of winter scoops pupate in spring, and gamma from autumn. In the spring, the first butterflies begin to appear, which lay the future offspring on young plants. After 60 - 70 days, a second wave of pests appears.
If the summer is hot, then the second generation of gamma butterflies does not lay eggs. Winter scoops in the second wave begin to fly in the afternoon, as they lack flowering plants. They begin to harm different plants, gnawing them.
Fighting caterpillars sometimes becomes long and laborious. First of all, if pests appeared on the bed, you need to collect and destroy them. Inspect as many leaves as possible and destroy the eggs. If the vegetables have obvious signs of eating up, but there are no pests themselves, then more radical measures should be launched.
To combat winter and gamma-scoop apply the same measures. They remove all weeds on and near the site, loosen the soil and treat the bushes with insecticides.
To prevent the appearance of caterpillars in spring and summer, butterflies are caught in pheromone traps. To do this, put cans with kvass, beer or another sweet natural drink. In spring and autumn, digging the soil to a depth of 25 cm or more is carried out. Discovered larvae and pupae are removed. Since the goose is very tenacious, it is necessary to carefully monitor to remove as much pest as possible, otherwise the plants will again be invaded by scoops.
Bell pepper is a healthy and tasty vegetable. Both people and insect pests love him equally. To protect the crop from spoilage, you need to consider the seasonal migration of butterflies.
The sooner the summer resident begins the fight with the caterpillar, the less harm it brings. Timely weed harvesting and the placement of simple traps will help deal with the hidden pest.
