Embodiment 1

[0022] The present embodiment provides a kind of composite mosquito-killing oil suspension comprising the following components by mass percentage: mosquito densovirus 10% (1 × 10 11 individual / mL), Bacillus thuringiensis subsp. Israel 1% (1×10 8 spores / mL), polycarboxylate 5%, fatty alcohol polyoxyethylene ether 8%, castor oil polyether 10%, organic bentonite 0.1%, and the balance is methyl oleate.

[0023] Mix and emulsify castor oil polyether and methyl oleate according to the formula in the above-mentioned examples, then add mosquito densovirus, Bacillus thuringiensis subsp. Machine shearing for 10 to 20 minutes to mix evenly, and then pass the mixture through a sand mill to obtain an oil suspension.

Embodiment 2

[0025] The present embodiment provides a kind of composite mosquito-killing oil suspension comprising the following components by mass percentage: mosquito densovirus 0.0001% (1 × 10 6 individuals / mL), Bacillus thuringiensis subsp. Israel 30% (1.5×10 10 spores / mL), alkyl phenyl ether sulfonate 1%, fatty alcohol polyethylene glycol ether sulfate 1%, alkylphenol polyether sulfate 10%, white carbon black 2.5%, and the balance is rapeseed oil .

[0026] Mix and emulsify alkylphenol polyether sulfate and rapeseed oil according to the formula in the above example, then add mosquito densovirus, Bacillus thuringiensis subsp. Sulphate and white carbon black are sheared with a shearing machine for 10-20 minutes and mixed evenly, and then the mixture is passed through a sand mill and sand-milled to obtain an oil suspension.

Embodiment 3

[0028] The present embodiment provides a kind of composite mosquito-killing oil suspension comprising the following components by mass percentage: mosquito densovirus 0.001% (1 × 10 7 individual / mL), Bacillus thuringiensis subsp. Israel 20% (1×10 10 spores / mL), alkyl sulfosuccinate 3%, sodium lauryl sulfate 5%, tristyrylphenol polyoxyethylene ether 4%, magnesium aluminum silicate 1%, and the balance is peanut oil.

[0029] Mix and emulsify tristyrylphenol polyoxyethylene ether and peanut oil according to the formula in the above examples, then add mosquito densovirus, Bacillus thuringiensis subsp. Israel, alkyl sulfosuccinate, sodium lauryl sulfate, Magnesium aluminum silicate is sheared with a shearing machine for 10-20 minutes and mixed evenly, and then the mixture is passed through a sand mill and sand-milled to obtain an oil suspension.

Abstract

The invention provides a compound mosquito-killing oil suspension, which comprises the following components in terms of mass percentage: 0.0001-10% of mosquito densovirus, 1-30% of Bacillus thuringiensis subsp. Wet agent 1-10%, emulsifier 1-10%, thickener 0.1-2.5%, and the rest is non-aqueous dispersion medium. The invention also discloses its preparation method. Through the synergistic effect of the mixed use of Bacillus thuringiensis subspecies Israel and mosquito densovirus, the invention complements the objective shortcomings of its single use, improves the effect of killing mosquitoes, reduces the amount of pesticide application, reduces the cost of pesticides, and delays mosquitoes’ response to a single agent. resistance, prolonging the lifespan of the potion.

Description

technical field [0001] The invention belongs to the technical field of insecticides, and in particular relates to a compound mosquito-killing oil suspension and a preparation method thereof. Background technique [0002] Mosquito larvae are called larvae, commonly known as somersault worms, which hatch from mosquito eggs in water. The larvae are slender and dark brown. They swim vertically up and down in the water, feed on bacteria and single-celled algae in the water, and breathe air. When breathing, the body is at an angle to the water surface so that the breathing tube is perpendicular to the water surface; Immediately dive into the bottom of the water, the larvae develop into pupae after molting for 4 times, the pupae can still move in the early stage, and they are basically immobile when they emerge, and then emerge into adult mosquitoes. [0003] In the hot summer, mosquitoes are rampant. They not only suck blood and disturb people’s sleep, but also spread diseases su...
