Embodiment Construction

[0013] The present invention is a Bacillus thuringiensis suspending agent for killing mosquitoes. It uses Bacillus thuringiensis as an active ingredient, and after the titer is determined, it is prepared into a suspension with a certain concentration. It is a pure biological For pesticides, the fermentation medium of Bacillus thuringiensis includes starch, vegetable protein, vegetable fat, and crude fiber. Among them, the culture medium is prepared with the following components in weight percentage: 3-4% corn starch, 3.5-4.5% soybean cake powder, 0.7-0.8% yeast powder, 0.3-0.5% peptone, 1.0-1.2% fish meal, The rest is water. Generally, 3.3% of corn starch, 4% of soybean cake powder, 0.725% of yeast powder, 0.4% of peptone, 1.05% of fish meal, and the rest are water. The fermentation temperature of Bacillus thuringiensis is 26~33℃, the ventilation rate is 1:1.2~1.6, and the pressure is 0.02~0.06pa / cm 2 , the stirring speed is 18-22 rpm, and the fermentation time is 30-45 hour...

Abstract

The present invention discloses a bacillus thuringiensis suspending agent for killing mosquitoes. The present invention is characterized in that the suspending agent takes the bacillus thuringiensis as the effective component; after potency determination, biologically fermented liquor is confected into a suspension with certain concentration; the percentage concentration of the bacillus thuringiensis in the suspension is 0.25 to 1.5 percent. The present invention is a hi-tech biological larvicidal preparation, which achieves the mosquito controlling effects of quickly and simply killing mosquito larva, effectively protecting environment and livestock and guaranteeing food safety as well as solves the popular mosquito hazard in the culturing farm.

Description

technical field [0001] The invention relates to the technical field of biogenic insecticides, and more specifically relates to a high-tech veterinary product that can effectively control the harm of mosquitoes, has no pollution to the environment, and is nontoxic to humans, livestock, poultry, fish, etc. Biomosquitocidal preparations. Background technique [0002] Mosquitoes are important medical insects and are closely related to human and animal diseases. In intensive farms, mosquitoes not only harass and sting humans and animals, but also cause itching, rashes, and dermatitis, which affect the rest of animals, affect the quality of semen of male animals, and can spread various serious mosquito-borne diseases. It is one of the "hazards" and is very harmful to human and animal health. For a long time, the application of chemical drugs to prevent and control has been the main mosquito control measure. However, as the types of chemical insecticides continue to increase and...
