Preparation method of special mosquito-killing preparation for livestock and poultry breeding house

Abstract

The invention discloses a preparation method of a special mosquito-killing preparation for livestock and poultry breeding houses, and belongs to the technical field of microorganism and enzyme compounded biological agents and is characterized by comprising a fermentation process, a pretreatment process, an extraction process, a separation process and compounding of a mosquito-killing preparation. According to the invention, the special mosquito-killing preparation is formed by compounding a mosquito killing streptomyces fermentation broth and enzyme so as to effectively kill mosquito larvae and reduce the survival rate of mosquitoes, wherein the enzyme can effectively decompose organic pollutants in the environment, so that the special mosquito-killing preparation plays a role in deodorizing a breeding house while killing mosquitoes so as to reduce breeding of the mosquitoes; and Streptomyces culicidicus thalli are separated from the fermentation broth to avoid the situation that the Streptomyces culicidicus thalli go bad and generate odor, chitinase is used for conducting wall breaking treatment on the Streptomyces culicidicus thalli , and then separation is conducted, so that the problem that effective components are lost due to the fact that the Streptomyces culicidicus thalli are separated from the fermentation broth is avoided, and the problems of difficulty in filtration and activity reduction caused by wall breaking are solved.

Description

Technical field: [0001] The invention belongs to the technical field of biological preparations compounded by microorganisms and enzymes, and more specifically relates to a preparation method of a mosquito-killing preparation specially used in livestock and poultry breeding pens. Background technique: [0002] In livestock and poultry breeding pens, due to the existence of septic tanks, drainage ditches, water ponds, water tanks, etc., and some organic waste such as excrement and scattered feed of livestock and poultry cannot be cleaned up in time, it is very easy to breed mosquitoes. It affects environmental sanitation, and mosquito bites may also spread diseases and endanger the health of livestock, poultry and farmers. [0003] In order to get rid of mosquitoes well, there are currently many means, such as installing blue light mosquito lamps or spraying mosquito repellent drugs, but installing blue light mosquito lamps is more effective for moths, and less effective for ...

Problems solved by technology

[0002] In livestock and poultry breeding pens, due to the existence of septic tanks, drainage ditches, water ponds, water tanks, etc., and some organic waste such as excrement and scattered feed of livestock and poultry cannot be cleaned up in time, it is very easy to breed mosquitoes. Affects environmental sanitation, and mosquito bites may also spread diseases, endangering the health of livestock, poultry and farmers

[0003] In order to get rid of mosquitoes well, there are currently many means, such as installing blue light mosquito lamps or spraying mosquito repellent drugs, but installing blue light mosquito lamps is more effective for moths, and less effective for mosquitoes. In order to provide better effect, it is necessary to add blue light The number of mosquito lamps will inevitably affect the lives of livestock and poultry; and spraying mosquito repellent drugs has certain safety hazards
