Description

The invention relates to agriculture, in particular, to the cultivation of beneficial insects and can be used to grow silkworm (Bombyx mori L). The known nutrient medium for the cultivation of a harmful bug. Wheat germ embryos, beer yeast autolysate, sucrose or glycerin, p-hydroxybenzoic acid methyl ester and distilled water are part of the nutrient medium for the noxious bug. The nutrition of the larvae of the harmful turtle by this medium provides; full cycle of pest development 1. The indicated nutrient medium is specific for a harmful turtle. A nutrient medium for growing mulberry shells is also known. A copra containing mulberry leaf powder, wheat germ powder, wheat flour, glucose, mineral salts, ascorbic acid. or, when used in coolant, with citric acid, propionic acid, distilled water 21. However, this environment does not allow a sufficient increase in the extension of the tracks and cocoons and the weight of the cocoons. The purpose of the invention is to increase the issuance of caterpillars and cocoons and an increase in cocoons. The goal is achieved by the fact that the nutrient medium additionally holds the potato starch at the eating ratio of components, sec.%: Leaf powder 13.5-1 ", 5 mulberries Wheat powder 10.5-11.5 germ 9.5-10.5 Wheat flour 2,6-2,8 Glucose O, 45-0.55 Mineral salts 0.15-0.25 Citric acid.
