SU755256A1 - Method of increasing productivity of silkworm moths - Google Patents

Description

The invention relates to the field of agriculture, namely the methods of artificial breeding of mulberry worm, and can be used in the production of cocoons.

There is a method of stimulating the productivity of the silkworm by spraying mulberry leaves with an aqueous solution of inorganic salt - cobalt chloride [].

There is also known a method of stimulating the productivity of the silkworm by spraying mulberry leaves with organic compounds of silicon-1-ethoxysilatrane [2].

Used compounds have insufficient biological activity

The purpose of the invention is to increase the silk content in the cocoons in the autumn.

This goal is achieved by using a 0.005% Ν, Ν'-diethanolantranilic acid (DETAK) water solution as a biostimulator at the rate of 10-25 ml of solution per 100 g of mulberry leaves.

An example. '100 * 0.5 g of mulberry leaves are sprayed with 20-25 ml and 10-15 ml of 0.00.5% aqueous Ν, Ν'-diethanol-tranilic acid solution 2 hours before feeding on mulberry larvae. The feeding of the silkworm enriched leaves begin with P age.

Fermenting at ΙΪ and Ι1Ϊ ages is produced · enriched with leaves (at the rate of 10-15 ml per 100 g of leaf), after two or three supplementary feeding with a dry unfortified leaf for 2 days.

At the end of X and Iη ages, before the haul also 2-3 times the caterpillars are fed with a dry, non-enriched leaf.

In 1U and U ages 1 day. after molting they are fed dry, non-enriched leaf, then enriched with leaves (at the rate of 20-25 ml per 100 g of leaf) for 3-4 days. From the sixth day. At the age before coconning, they feed the dry unenriched leaf.

The productivity of the silkworm (Table 1), technological indicators of cocoons (Table 2) were investigated by quantitative and weight analysis.
