Abstract

The invention discloses a silkworm cocoon weighing and whitening powder as well as a preparation method and use method thereof, and belongs to the technical field of silkworm medicines. The silkworm cocoon weighing and whitening powder is made of brown sugar or white sugar and a methoprene emulsion in water, wherein the weight ratio of the brown sugar or white sugar to the methoprene emulsion in water is (100:9)-(100:18); the mass percentage of methoprene in the methoprene emulsion in water is 4-4.5%. The invention further discloses a preparation method and a use method of the silkworm cocoon weighing and whitening powder. By adopting the powder disclosed by the invention, defects of a methoprene liquid agent in the prior art can be overcome, the methoprene is prepared into a powder agent for the first time in China, in addition, the expiration date can be greater than or equal to 9 months. The powder disclosed by the invention is high in security and low in transportation cost. The powder can be applied to fifth instar larvae, the silkworm cocoon amount can be increased by 15-20%, in addition, the silkworm cocoon is good in whiteness, the silkworm cocoon grade is high, the price of the silkworm cocoon can be increased, and remarkable economic benefits can be made; moreover, the disease ratio or death ratio of the fifth instar larvae can be reduced.

Description

technical field [0001] The invention relates to silkworm cocoon weight gain, whitening powder, a preparation method and a use method thereof, and belongs to the technical field of silkworm medicine. Background technique [0002] Methoprene is a biological growth-regulating hormone, which can be used as a juvenile hormone and used in silkworm medicine. It can prolong the silkworm larvae period, prolong the cocooning time by 1-2 days, increase the amount of cocooning by 15%-20%, and increase the cocooning rate at the same time. Whiteness, significantly improve the quality of silkworm cocoons. [0003] Due to the low solubility of methoprene in water, the current formulations of methoprene are mostly liquid, such as water emulsions and oils. These formulations often contain volatile organic solvents and high water content, resulting in low product safety and high transportation costs. [0004] In view of this, it is necessary to provide a new cocoon weight-increasing and white...
