Breeding technology of Bracon hebetor and other entomophages in biofactories

Currently, one of the main problems is the reform of the management system of the agricultural sector, the rational use of land and water resources, as well as the protection of harmful organisms by means of predatory and free-feeding and microbiological preparations. If we solve these problems and protect agricultural crops in a biological way, we will provide the population of our country with ecologically clean products with complete food safety. For this purpose, there are currently more than 700 bio laboratories operating in the republic, where mainly 4 types of entomophagous are bred (poacher, egg-eating Trichogramma, goldeneye, and The European mantis). Bracon hebetor paralyzes middle-aged and older hookworms and lays its eggs on their bodies. Hatched larvae feed on worms. There are 4 types of it in Uzbekistan. Bracon bites one hundred and fifty worms in one day and causes paralysis. Its many types of owlet moths damage 3-4 year old worms. After release, poachers spread to a distance of 100-150 m during the day. Bracon is highly effective for environmental and warm-blooded creatures in general

This scientific article provides experimental material devoted to the study of the influence of varietal characteristics of peach and schemes for placing trees in the garden, using weak vegetatively propagated rootstocks. Experiments have shown that an increase in the density of peach distribution in the orchard grown on the VSV-1 rootstock contributes to a reduction in the crown volume from 16.99 to 9.15 m3 / v., The VVA-1 rootstock - from 16.99 to 9.15 m3 / v. ., rootstock GF-667 - from 16.25 to 7.94 m3 / v. The same pattern persists in the formation of the projection and saturation of the crown with leaves. However, in terms of 1 hectare of the garden, the value of these signs increases 1.9-2.3 times.Growing a peach of the Lola variety on weak vegetatively propagated rootstocks VSV-1, VVA-1 and GF-667, with thickened placement of trees in the garden 5.0x2.0 meters, allows you to receive a net profit from the use of the new technology in the amount of 89.929 - 94.917 million soums / ha, with the cost of fruit production 299.2-315.4%.
