Abstract

A method for treatment of silk-worm eggs prior to incubation with aqueous solution of chlorantoin as antiseptic.

Description

The useful model refers to agriculture, in particular, to sericulture and can be used in the process of growing mulberry and oak silkworms.

There is a known method of processing silkworm silkworm, which includes its treatment with an aqueous solution of a chemical compound - benzoic acid - at a concentration of 0.001-0.01 95 (Patent of Ukraine Mo 12372 A. Method of processing silkworm silk /

Publ. 28.02.97. - Bull. Me 1). However, the use of the known method does not ensure the maximum disinfection of silkworms from bacterial, fungal and viral infections, and also does not ensure a sufficient increase in the viability and productivity of the silkworm.

The task of the useful model is to improve the method of processing silkworm silkworms by using an aqueous solution of chlorantoin, which is an affordable and harmless disinfectant with a cleaning effect. Its solutions do not have an irritating effect on the skin and their use by dipping objects and wiping in the presence of people without respiratory protection is permissible, as well as they do not bleach fabrics and do not damage the used objects made of rubber, wood, metal, enamel, glass, tiles, polymer materials (Methodological instructions

of the Ministry of Health of Ukraine on the use of chlorantoin for the purpose of disinfection. Approved by the Chief State Sanitary Doctor on August 3, 1999 under Order No. 0178-99). Chlorantoin has a wide spectrum of antimicrobial action, which provides a high bactericidal, fungicidal and virulocidal effect and increases the viability and silk productivity of beneficial silkworms.

The task set by the useful model is solved by the fact that, in the method of processing the silkworm silkworm, which includes treating the silkworm with an aqueous solution of a chemical compound, according to the useful model, the silkworm is treated with 0.2-0.3 96 of an aqueous solution of the antiseptic chlorantoin before incubation, with an exposure of 10-15 minutes.

Example. In the experiment, mulberry silkworms of the breeds B-1, B-2, Merefa-b,

Merefa-7, as well as the grain of the oak silkworm of the Polisky tasar breed. In the experimental version, grain was treated with 0.1: 0.2; 0.3 and 0.4 95 aqueous solutions of chlorantoin at exposure for 5, 10, 15 and 20 minutes, then washed with water and dried. The grain of the control variant was not subject to any influences. The data given in table. 1, show that the use of the chlorantoin preparation provides a 98.0-100,956 disinfecting effect against pathogens of perineum, bacterial and fungal diseases, as well as against the nuclear polyhedrosis virus (Table 2).

The use of the proposed method of grain processing contributes to ensuring high indicators of viability of grain and caterpillars, as well as increases indicators of silk productivity (Table 3).

The use of a 0.2-0.3 95 solution of the drug increases the viability of silkworm larvae and caterpillars by 3) - 3.3 95 and 16.0 - 29.4 956 oak silkworm, compared to the control and by 19.0 and 27.0 95, compared to the prototype.

When using 0.1 95 and 0.4 95 chlorantoin solution, indicators of viability and productivity of mulberry and oak silkworms were close to the control or slightly higher.

The use of 0.2-0.3 95% solution of chlorantoin for the treatment of sorghum after exposure for 10-15 minutes ensures its disinfection from pathogens of bacteria and mycoses, and also contributes to ensuring high indicators of viability and silk productivity. Thus, the proposed method makes it possible to fight the infection of beneficial silkworms and improve the quality of raw silk.

Claims (1)

The method of processing silkworm larvae, which includes processing the larvae with an aqueous solution of a chemical compound, which differs in that the larvae are treated with a 0.2-0.396 aqueous solution of the antiseptic chlorantoin during exposure for 10-15 minutes before incubation.
