Embodiment 1

[0018] Weigh respectively p-tert-butylphenol (38%), 2,4-di-tert-butylphenol (17%), 2,6-di-tert-butylphenol (25%), 2-tert-butylphenol (14% ), 2,4,6-tri-tert-butylphenol (6%), a total of 36g, dissolved with 9.4g ethyl acetate solution, added 4.3g Tween, dissolved, according to the conventional process, the present invention is used to kill mosquitoes The larvae preparation is then diluted with water in the prepared preparation for killing mosquito larvae, so that the concentration of the raw material drug is 5%. Finally, the diluted biological insecticide was tested for indoor biological activity on mosquito larvae-larvae, and the method was carried out according to the immersion method in the bioassay SOP of the National Southern Pesticide Innovation Center. After 24 hours, the number of dead and alive insects in each treatment was investigated, and the control effect was 82.8%.

Embodiment 2

[0020] Weigh respectively p-tert-butylphenol (11%), 2,4-di-tert-butylphenol (29%), 2,6-di-tert-butylphenol (30%), 2-tert-butylphenol (6% ), 2,4,6-tri-tert-butylphenol (24%), 64g in total, dissolve with 19g ethanol, add emulsifier etc. 9.9g therein, according to conventional technology, make the present invention and be used for killing mosquito larvae, Then add water to dilute the prepared preparation for killing mosquito larvae, so that the concentration of the raw material drug is 8%. Finally, the biological activity of the diluted biopesticide on mosquito larvae-larvae was determined indoors, and the method was carried out according to the immersion method in the bioassay SOP of the National Southern Pesticide Innovation Center. After 24 hours, the number of dead and alive insects in each treatment was investigated, and the control effect was 91.4%.

Embodiment 3

[0022] Weigh respectively p-tert-butylphenol (5%), 2,4-di-tert-butylphenol (24%), 2,6-di-tert-butylphenol (21%), 2-tert-butylphenol (30% ), 2,4,6-tri-tert-butylphenol (20%), a total of 102g, dissolved in 54g acetone, adding 50g of emulsifier Span etc., according to the conventional process, the present invention is used to kill mosquito larvae , and then add water to dilute the prepared preparation for killing mosquito larvae, so that the concentration of the raw material drug is 1.1%. Finally, the biological activity of the diluted biopesticide on mosquito larvae-larvae was determined indoors, and the method was carried out according to the immersion method in the bioassay SOP of the National Southern Pesticide Innovation Center. After 24 hours, the number of dead and alive insects in each treatment was investigated, and the control effect was 76.2%.

Abstract

The present invention provides a mosquito larvae exterminating preparation, a preparation method therefor and applications thereof. The preparation consists of tert-butylphenol compounds and conventional auxiliaries, wherein the mass of the tert-butylphenol compounds accounts for 0.05-99% of the mass of the exterminating preparation, while the mass of the conventional auxiliaries accounts for 1-99.95% of the mass of the exterminating preparation. The present invention provides a novel harmonious insecticide which is safe for humans and animals, and is environmentally-friendly. The exterminating preparation has profound significance in ecological environmental protection, human health, and comprehensive treatment of diseases.

Description

technical field [0001] The invention relates to a preparation for killing mosquito larvae in the technical field of biological control of hygienic insect pests and a preparation method thereof, in particular to a preparation for killing mosquito larvae containing tert-butylphenol compounds and its preparation and application. Background technique [0002] Mosquitoes are tiny flying insects with piercing-sucking mouthparts and are one of the four pests. The deadliest animal in the world ranks NO.1 mosquito, which kills more than 725,000 people every year. Usually the females feed on blood, while the males drink the sap of plants. Mosquitoes have their own anti-virus organs and cannot transmit viruses through bites. Blood-sucking female mosquitoes are intermediate hosts for other pathogens such as dengue fever, malaria, yellow fever, filariasis, and Japanese encephalitis. [0003] At present, the main components of mosquito killers on the market are pyrethroids, such as tetr...
