The invention belongs to the technical field of mosquito larva prevention and control, and particularly relates to a mosquito-killing spreading oil agent and a preparation method and application thereof.The mosquito-killing spreading oil agent is composed of nerolidol, eugenol, methyl oleate, surfactants OP-4 and OP-10 and oleic acid, the mass percent of methyl oleate is 85%, the mass percent of a mixed preparation prepared from the surfactants OP-4 and OP-10 according to the mass ratio of 1: 1 is 5%, and the mass percent of oleic acid is 5%. The mosquito larva killing rate of the film spreading oil agent product within 60 minutes is 100%. Under the same condition, the effect of the insecticidal composition is better than that of pyrethrin, and the insecticidal speed is higher. The film spreading oil agent can reduce the chemical pesticide resistance of deet, and also can achieve the effects of environmental protection and efficient killing of mosquito larvae.

Provided is a composition containing natural pyrethrin, a radical chain inhibitor, a peroxide decomposer, and a solvent. The ratio (V2 / V1) of the viscosity V2 (mPa・s) of the composition after storage at 90°C for 3 weeks to the viscosity V1 (mPa・s) of the initial composition is 1-5.

The invention belongs to the field of chemical ecology of agricultural pests and pesticide science, and relates to an insecticide composition for improving the sensitivity of agricultural pests to insecticides and application of the insecticide composition. Folic acid is applied to a pest feeding substrate, a host plant or a feed, so that the sensitivity of pests to various insecticides (including neonicotinoids, pyrimidines, pyrethroids, organophosphorus and the like) can be remarkably enhanced. It is found that folic acid can regulate and control a carbon metabolism network in pests and inhibit cytochrome P450 and other detoxification enzyme related pathways, and then the endurance capacity of the pests to insecticides is reduced. The composition and the method are verified in seven important pests such as brown planthopper, sogatella furcifera, spodoptera frugiperda, cotton aphid, chilo suppressalis, panonychus citri and thrips, have the advantages of improving the pesticide effect, reducing the pesticide application amount and delaying the resistance evolution, and can be widely applied to comprehensive treatment of agricultural pests.

A slow-release insect repellent sheet is provided, which allows for easy adjustment of the release period of pyrethroid insecticides. The slow-release insect repellent sheet is a sheet containing a liquid component, wherein a filler is dispersed in a thermoplastic resin and a liquid component is loaded in the voids formed around the filler, wherein the loaded liquid component contains a pyrethroid insecticide as the active ingredient and contains a surfactant and / or liquid paraffin.

The invention belongs to the field of textile auxiliaries, and provides water-soluble wool lubricating oil, a preparation method thereof and application of the water-soluble wool lubricating oil to improvement of textile performance. The water-soluble wool lubricating oil is prepared from the following components: polyethylene glycol laurate, sorbitol laurate, a polyoxyethylene polyoxypropylene block copolymer, isothiazolinone, castor oil polyoxyethylene ether and an auxiliary agent. The water-soluble wool lubricating oil provided by the invention further comprises one or more of flavonoids extracted from natural plants, 3-(trimethoxysilyl) propyl dimethyl octadecyl amine chloride and pyrethroid. The wool lubricating oil provided by the invention has mothproof, antibacterial and enzyme-proof effects on textiles. The technical problems that a traditional mothproof agent, a traditional antibacterial agent and a traditional enzyme-proof agent in the domestic wool spinning industry are insoluble in water, uneven in wool blending and poor in effect, spinning is affected, and even the strength of yarn, the spinnability of fiber and the yield are affected can be effectively solved.

The application discloses a bio-pesticide containing bistrifluron and pyrethrin, and the bio-pesticide containing bistrifluron and pyrethrin can be effectively used for preventing and treating Bemisia tabaci.

Provided is a composition for insect pest control containing natural pyrethrin, a radical chain inhibitor, a peroxide decomposer, and a solvent. Said composition releases natural pyrethrin at a transpiration rate in a range of 0.1 mg / hour to 2.0 mg / hour when heated for 116 hours at 140℃.

The present invention provides a stable oil in water agrochemical composition of pyrethroid that is compatible with fertilizers, to the use of particle size reducing adjuvants for the stabilization of said oil in water agrochemical compositions, to a method of the preparation of the stable oil in water pyrethroid agrochemical compositions, and to a method for controlling insect pest by the aforementioned oil in water agrochemical compositions.
