Problems solved by technology

[0004] In my country, mosquito control has long relied on non-selective organochlorines, organophosphorus, carbamate compounds and pyrethroids; the aforementioned several drugs all have non-target biological toxicity, environmental pollution, and target biological drug resistance. These disadvantages make the effect of the aforementioned drugs weaker and weaker, which is a major factor in the outbreak of mosquitoes and mosquito-borne diseases in recent years

Embodiment Construction

[0027] Specific examples are provided below to further illustrate the present invention, so that those skilled in the art can better understand the present invention and implement it, but the given examples are not intended to limit the present invention.

[0028] How the example was made:

[0029] 1) Weigh the required components as shown in Table 1;

[0030] 2) mixing the insect juvenile hormone analogue and emulsifier until completely emulsified, to obtain A;

[0031] 3) Spray A on the carrier, and continuously rotate and mix the carrier during the spraying process;

[0032] 4) While stirring and mixing, slowly add Bacillus thuringiensis israeli varietal powder, if there is vegetable oil in the component, then add vegetable oil;

[0033] 5) Continue to stir until the attachments on the surface of the carrier are evenly covered to obtain a finished product.

[0034] 6) Put the finished product in a vacuum moisture-proof bag (20 kg) for large-scale application, or in a wat...

Abstract

The invention discloses a harmless mosquito larva killing composition and a preparation method thereof. The composition comprises bacillus thuringiensis vav israelensis, insect juvenoid, an emulsifier, a carrier and optional plant oil, wherein the carrier is quartz sand or volcanic lava granules; the insect juvenoid is pyriproxyfen and / or methoprene. The preparation method comprises steps of emulsification, spraying, mixing, stirring, covering and the like. The composition disclosed by the invention is prepared by compounding purely natural soil bacterium products and artificially synthesizedinsect juvenoid, has the beneficial effects of quick-acting effects and slow effects, non-target bio-safety and no drug resistance, is free of pollution or residue in environment protection, and has high plant permeability. After vacuum sealing and packaging, a finished product of the composition disclosed by the invention can be preserved for two years under the condition of the room temperature.

Description

technical field [0001] The invention relates to the field of public health, in particular to a composition for harmlessly killing mosquito larvae and a preparation method thereof. Background technique [0002] Mosquitoes are the primary vectors of several human and animal diseases including malaria, yellow fever and dengue. Each year more than 1 million people die from mosquito-borne diseases, and hundreds of millions more suffer and suffer from mosquito-borne diseases. [0003] There is neither a cure nor a vaccine for dengue. Currently the only way to control the disease is to control the mosquitoes that transmit the disease, namely Aedes aegypti and Aedes albppictus. There is no cure for yellow fever, but there is a vaccine; however, the vaccine is expensive and not available to protect the rest of the world. There is currently no drug regimen available that guarantees 100% protection against malaria, and prevention of infection requires directed use of antimalarial dr...
