Abstract: One of the economically valuable insects is silkworm the rapid change of growth phases of which makes it an interesting object of researches on growth subject and development of larvae. Apart from antitumor activity synthesized organoselenium compound 2-dibutylaminoselenol-1("selenol") exhibited growth stimulant properties of a silkworm. Among organoselenium compounds sodium salt of selenious acid (Na2SeO3) is the most common as the growth stimulant of silkworm. Advantage of sodium selenite over other stimulants is its effectiveness at small concentration on live weight of caterpillars (totally 30-40 mg for 1 kg of live weight). Disadvantage of using selenite is shown in lower value of silk-screening, activity of caterpillars, productivity of cocoons from a box of caterpillars. Therefore, while conducting researches to study the stimulation properties of “selenol†we compared actions of the latter to the data of sodium selenite. To carry out experiments "selenol" was dissolved in distilled water (6 mg of medicine for 1 kg of live weight of caterpillars) and mulberry leaves were sprayed with the solution. It is should be emphasized that "selenol" consumption is 5-6 times less by weight than the consumption of sodium selenite. Caterpillars were fed on these leaves from 2d day of 4th age, at each age - 1 time (only 2 times). Feeding of caterpillars was carried out in threefold replication of each group for 150 caterpillars.Tests of "selenol" as a biostimulator of a silkworm were performed at 12 sites (kumkhana – small industrial farms). As a result of using this medicine it was possible to get a good harvest: 267 kg harvest was got per 95 g of a grain (a grain – eggs of silkworm moth). Given that annual average plan of a small farm makes 15 tonnes, then the increase in a harvest of cocoons using "selenol" will make about 790 kg.
