Summer cabbage fly loves cabbage more than anything else. However, at the same time, she is not at all averse to feasting on radish with radishes, as well as a number of other cabbage crops. Despite the fact that one-year generation is characteristic of these voracious parasites, they bring a lot of harm. They are especially harmful to late distillation cauliflower and late varieties of the beloved white cabbage. And if you do not drive vigilant pests from the site, you will have to generously share with them the fruits of your labors
Meet the pest
The adult size of summer cabbage flies is about 7 - 8 mm. Gluttonous pests are endowed with transparent yellowish-brownish wings with small yellowish veins. And the flies themselves are distinguished by a yellowish-gray color.
The eggs of summer cabbage flies, reaching in size from 1 to 1, 1 mm, are cigar-shaped, painted white and equipped with rather wide grooves. The larvae of these pests can be either yellowish or white. As a rule, they grow up to ten millimeters in length. All larvae are characterized by the absence of legs and pronounced head capsules. The posterior tips of their bodies are slightly widened and endowed with fourteen conical tubercles, while only six of them can be seen (only the lower tubercles). All these formations are at the same distance in relation to each other. In the middle of the body of the larvae they are distinguished by a characteristic luster, and the anterior and posterior segments of their bodies are always dull. Puparia, the size of which is about 6, 5 - 7 mm, also have six tubercles on the posterior sites.
Summer cabbage fly pupae overwinter at a depth of ten to thirty centimeters in the soil. At the end of May, as well as at the beginning of June, flies start flying. As a rule, the soil at the depth of occurrence of the parasites by this time has time to warm up to eighteen degrees. And after about a week and a half, when the additional feeding of summer cabbage flies with flower nectar is completed, the females begin to lay eggs. Often, the process of mass egg-laying coincides in time with the summer of spring cabbage flies of the second generation.
Eggs are laid by females in twenty to forty pieces either on the root collars of growing crops, or on the soil near the root necks. Their total fertility reaches from one hundred to one and a half hundred eggs. After 5 - 12 days, voracious larvae feeding on plant roots hatch. They usually develop for thirty to forty days, after which they leave forage crops and begin to pupate in fake cocoons.
The habitat of summer cabbage flies is quite extensive - it covers the entire territory of Russia and reaches distant North America. In addition, this keen-sighted pest can often be found in Western Europe (in the middle and northern lane).
How to fight
In order to significantly limit the number of summer cabbage flies, it is recommended to carry out deep autumn plowing immediately after harvesting the cabbage crop. Timely control of attacking weeds is no less important.
When growing cabbage, it is best to look for varieties that are more resistant to attacks from the summer cabbage fly. As for the seedlings, it is not worth it to deepen it unnecessarily during planting, since in this case the danger of its damage by gluttonous parasites increases significantly.
During the growing season, cabbage must be systematically hilled, watered regularly and fed with high-quality fertilizers. These measures contribute to the formation of additional root layers on the hilled parts of the stems and increase the resistance of growing crops to damage.
After the harvest of cabbage of early maturing varieties is harvested from the site, it is necessary to promptly remove all stubs - a huge number of pest larvae can concentrate in them. And if the number of summer cabbage flies on the site is especially high, they switch to insecticide treatments.
