Description
Technical field
The present invention relates to field of public health, specially a kind of innoxious composition for killing mosquito larvae and its preparation side
Method.
Background technique
Mosquito is the main vector of a variety of human and animal's diseases including malaria, yellow fever and dengue fever.It is annual super
The disease that 1,000,000 people die of killing propagation is crossed, several hundred million people are even more to undergo pain and with the disease by killing propagation.
For dengue fever both without specific drug or without vaccine.The sole mode for controlling the disease at present is that disease is propagated in control
The mosquito of disease, i.e. Aedes aegypti (Aedes aegypti) and aedes albopictus (Aedes albppictus).Yellow fever is not controlled
Treatment method, but have vaccine；However vaccine is expensive, can not obtain other areas to protect the world.Currently without obtainable
Pharmaceutical admixtures guarantee 100% protection for malaria, and other than preventing bite by mosquitos, the prevention of infection is needed by guidance
Use anti-malaria medicaments.Anti-Malarial is actually not to prevent the disease, but only work in blood flow by inhibiting red
Parasitic animal and plant in cell develops to inhibit clinical symptoms.
In China, what mosquito control relied on for a long time is non-selective organochlorine, organic phosphorus, carbamates
Close object and pyrethroid；There is non-target organism toxicity, environmental pollution, target biomolecule resistants etc. for multiple medications above-mentioned
A variety of inevitable drawbacks, these drawbacks make foregoing pharmaceutical effect more and more weaker, and exactly mosquito and mosquito matchmaker's disease are sudden and violent in recent years
Send out a popular big factor.
Summary of the invention
The first purpose of the invention is to provide a kind of innoxious compositions for killing mosquito larvae larva.Of the invention
Two purposes are to provide the preparation method of above-mentioned composition.
The first purpose of this invention can be achieved by the following technical programs:
A kind of innoxious composition for killing mosquito larvae, which is characterized in that calculating by percentage to the quality includes with the following group
Point:
Preferably, component further includes vegetable oil, and content is 2.0-5.0% mass percent.
Preferably, the carrier is 30-40 mesh, the quartz sand of 400-600 micron diameter.
Preferably, the carrier is slag particle.
Preferably, the emulsifier is Triton-100.
Preferably, the corpus allatum hormone analog is Nylar and/or methoprene；When corpus allatum hormone analog
Its content is 0.05-0.5% mass percent when for Nylar, and when corpus allatum hormone analog is methoprene, content is
0.25-5% mass percent.
Second object of the present invention can be achieved by the following technical programs:
A kind of preparation method of the above-mentioned innoxious composition for killing mosquito larvae, comprising the following steps:
1) it takes the corpus allatum hormone analog of above-mentioned mass percent and emulsifier to mix to complete emulsification, obtains A；
2) A is sprayed on carrier, and is constantly stirred carrier during sprinkling；
3) Bacillus thuringiensis var.israelensis de Barjac bacterium powder is continuously added in whipping process；
4) it stirs to the surface attachments covering on carrier uniformly, obtains finished product.
Bacillus thuringiensis var.israelensis de Barjac used in the present invention is insecticidal active ingredient, and finished product potency is in 100-
Between 400/mg, bacterium powder, potency substantially 7000/mg are used in the production process.Bacillus thuringiensis var.israelensis de Barjac is
A kind of mosquito children midfield toxic protein, can rapidly kill mosquito larvae.
Corpus allatum hormone analog used in the present invention includes Nylar and/or methoprene, is another desinsection
Effective component has growth regulating effect to mosquito larvae, can upset the normal processes of mosquito larvae pupa emergence.
Emulsifier used in the present invention is Triton X-100 (Triton X-100), is a kind of non-ionic
Surfactant.Emulsion can be formed as setting up bridge between water phase in oil.Remaining emulsifier can also make according to demand
With.
Carrier used in the present invention is 30-40 mesh (400-600 micron diameter) pure quartz sand, it is desirable that surface is without dust etc.
Impurity attachment, has the advantages that high specific gravity and high-specific surface area.The pure quartz sand of 30-40 mesh can be substituted with slag particle,
The density and granular size of slag particle are needed with the close of the pure quartz sand of 30-40 mesh.
It, can be suitably in composition if necessary to improve the content of the Bacillus thuringiensis var.israelensis de Barjac in composition through a step
Middle addition vegetable oil, as natural adhesive.
Compared with prior art, composition made of the present invention is that pure natural soil bacteria product and artificial synthesized insect protect
The compounding of young hormone analogs；There is quick-acting, residual effect, non-target organism safety and the beneficial effect without drug resistance in terms of effect.
In addition, the manufactured pollution-free noresidue of composition, has high vegetation penetration power, uniform fold is easy production, and performance is steady
Fixed, storage transport is easy to use, environmentally friendly.After composition finished product vacuum sealed package made of the present invention, in room temperature item
It can be saved under part 2 years.
Specific embodiment
Specific embodiment is provided below, and the invention will be further described, so that those skilled in the art can preferably manage
The solution present invention can be simultaneously practiced, but illustrated embodiment is not as a limitation of the invention.
The production method of embodiment:
1) component needed for weighing as shown in table 1；
2) corpus allatum hormone analog and emulsifier are mixed agitation to mix to complete emulsification, obtains A；
3) A is sprayed on carrier, and so continuous that mix carrier Stirring during sprinkling；
4) while being stirred, Bacillus thuringiensis var.israelensis de Barjac bacterium powder is slowly added, as having plant in component
Oily then plus vegetable oil；
5) continue to stir, until carrier surface attachment covering uniformly, obtain finished product.
6) finished product is packed into vacuum damp-proofing bag (20 kilograms) in large-scale application of pesticides or water-soluble cellulose vacuum bag
(10 grams/bag) are used for processing small water.
