Cabbage from time immemorial is a favorite vegetable crop in our country. It is hard to imagine the Russian table without sauerkraut or stewed cabbage, borscht, cabbage rolls and all kinds of salads. It is not surprising that many gardeners prefer to grow this crop themselves. This is also stimulated by the great variety of varieties that have recently appeared - not only white cabbage, but also cauliflower, kohlrabi and broccoli ... However, to grow a beautiful and large cabbage is not easy. And it's not just about watering and feeding, which cabbage is very fond of. Cabbage has the most real enemies - caterpillars.
Caterpillars - a dangerous pest of cabbage
The most common pest of cabbage is the cabbage butterfly, cabbage whitefly. Caterpillars emerge from the eggs laid on cabbage leaves within a few days. They eat the same leaf on which they were born, but as they grow older, the eating speed and amount eaten increases greatly. Though they do not live long, about 2-4 weeks, but even during this time they have time to spoil cabbage yield.
Addition of insect development is known to everybody since school: larva-pupa-butterfly, and further the cycle repeats. It was found that 2-5 generations of this pest may appear during summer, and the new ones may finish what they did not finish.
Cabbage moth and cabbage moth caterpillars are no less dangerous. All of them produce several generations of caterpillars during one summer, causing great harm to yield of all cabbage species.
The cabbage moth is especially dangerous for cauliflower. The larvae of this pest penetrate into heads of cabbage, gnaw through real mazes in inflorescences, and obstruct the entire space with their excrements.
Compliance with basic agricultural techniques - weeding, loosening, hilling, thorough removal of plant residues and soil recultivation in autumn allows to significantly reduce the risk of unwanted guests, but, unfortunately, does not exclude it completely.
