The invention discloses an environment-friendly water-based aerosol insecticide composition, which belongs to the field of chemistry. The environment-friendly water-based aerosol insecticide composition comprises the following compositions in percentage by weight: 0.03-0.5% of transfluthrin, 0.02-0.3% of permethrin cypermethrin, 1.5-3% of sorbitan monooleate, 6-10% of odorless kerosene, 30-70% of deionized water and 30-50% of propellant. Since in the environment-friendly water-based aerosol insecticide composition, water is used as solvent, unpleasant smell of kerosene is not generated after spraying, and grease or smudges is not left at the position of dropping the fogdrop. Furthermore, due to the use of 1,1, 1,2-tetrafluoroethane or 1,2-difluoroethane which is non-flammable and dose not cause the greenhouse effect as a propellant, the water-based aerosol insecticide composition, as a household insecticide aerosol, is more environmentally friendly and is much safer to use.

The present invention provides a insect-proofing agent, which has high insect-proofing effect, at the same time, can display using terminal definitely due to the volatilization of normal temperature volatility medicament and the sublimation of subliming material end at one time, also manufacturability is excellent. The insect-proofing agent is characterized in that it contains medicament carrier by pliability bag, the medicament carrier is made by making one or two normal temperature volatility medicament selected from the eneyne pyrethrin, tetrafluoro pyrethrin, bingfu pyrethrin and methoxy benzyl fluorine pyrethrin to be carried on subliming material with 0.5 to 2.0 percent by weight. The two or single surface of the pliability bag is coated with japanese paper or non-slub cloth of 10 to 50g / m<2> and medicament permeance film which wall thickness is 10 to 30 [mu]m, under the state of single surface, the other surface is formed by non permeating film, and at least parts of the medicament carrier can contact to the inner surface of the pliability bag even though the medicament carrier reduces along with the sublimation of the subliming material, thus, the using terminal can be identified by watching the disappear state of the medicament carrier.

The object of the present invention is to provide an insect repellent which has high insect repelling efficacy and which can clearly show the end point of use because the volatilization of the volatile agent at room temperature and the sublimation of the sublimation substance are completed almost simultaneously, and is excellent in manufacturability. The present invention solves the above-mentioned problems by providing the following insect repellent, that is, an insect repellent characterized in that it is an insect repellent containing a drug carrier in a flexible bag, and the drug carrier is selected from One or two normal-temperature volatile agents selected from ethynthrin, transfluthrin, profluthrin, and metofluthrin are supported on a sublimable substance at 0.5 to 2.0% by weight Both sides or one side of the flexible bag is Japanese paper or non-woven fabric with a permeable weight of 10-50 g / m2 laminated with a drug-permeable film with a wall thickness of 10-30 μm. In the case of one side Next, the other surface is formed of a drug-impermeable film, and at least a part of the drug carrier is in contact with the inner surface of the flexible bag even if the drug carrier shrinks with the sublimation of the sublimation substance, The end of use can be confirmed by visually observing the disappearance state of the above-mentioned drug carrier.

The invention discloses a dinotefuran-containing compound insecticidal composition and application thereof, wherein active ingredients comprise dinotefuran and tetramethylfluthrin or transfluthrin, the weight ratio of dinotefuran to tetramethylfluthrin is (1:15)-(15:1), preferably (1:4)-(8:1), and the weight ratio of dinotefuran to transfluthrin is (1:15)-(15:1), preferably (1:3)-(8:1). According to the insecticide, dinotefuran and tetramethylfluthrin or transfluthrin are compounded and processed into emulsion in water or microemulsion, so that use of organic solvents is reduced, and the insecticide is more environmentally friendly, wherein tetramethylfluthrin or transfluthrin has an excellent knockdown property on public health pests such as mosquitoes, flies and the like, and due to the lethal effect of dinotefuran, the bactericidal composition has a remarkable synergistic effect on prevention and treatment of public health pests, the application amount of the pesticide can be reduced, the cost is saved, and the drug resistance of the pests is delayed.

A composite insecticidal composition is disclosed that contains three active ingredients, which are transfluthrin, prallethrin, and cypermethrin. The composite insecticide composition may further contain at least one of a solvent and a propellant. The weight percentage of each of the active ingredients may be about 0.05% to 0.5%.

The invention discloses peppermint essential oil mosquito liquid and a preparation method thereof. The peppermint essential oil mosquito liquid is prepared from, by weight, 0.5-2.5 parts of transfluthrin, 0.1-0.5 part of peppermint essential oil, 50-60 parts of diethylene glycol butyl ether, 0.05-0.15 part of 4-sodium cumenesulfonate, 0.1-0.5 part of synergist, 0.1-0.5 part of antioxidant and 35-45 parts of water. The peppermint essential oil mosquito liquid is fresh and fragrant in smell, has a strong dispelling and killing effect on mosquitoes, is environmentally friendly, strong in effect, safe, inflammable and stable in volatilization, can lower the indoor organic volatile content, and is an ideal choice for healthy home life.

The invention discloses a novel thiomethrin chemical modification and its preparation method and application. The present invention mainly transforms a terminal chlorine atom and an ester group on the transfluthrin, replaces a terminal chlorine atom with a trifluoromethyl group, and replaces the ester group with a thiol ester group structure, A series of novel thiomethrin compound structures containing a thiol structure are formed. These novel thiomethrin chemical modifications can improve metabolic stability and reduce environmental toxicity, and have certain insecticidal effects on larvae. Phenethrin is basically at the same concentration level, showing a mosquito-killing effect similar to that of bifenthrin, and can effectively solve the serious problem of outstanding resistance to existing pyrethroid insecticides. In addition, the invention has the advantages of simple reaction process, few reaction steps, high synthesis yield, short reaction cycle, good repeatability and the like.

The invention discloses a compound insecticidal composition containing dinotefuran and its application. The weight ratio of esters is 1:15-15:1, preferably 1:4-8:1; the weight ratio of dinotefuran and transfluthrin is 1:15-15:1, preferably 1:3-8: 1. The insecticide described in the present invention is processed into aqueous emulsion or microemulsion by compounding dinotefuran and transfluthrin or transfluthrin, which reduces the use of organic solvents and is more friendly to the environment. Biflufenthrin or transfluthrin has excellent knockdown properties against mosquitoes, flies and other public health pests, and the lethal effect of dinotefuran has a significant synergistic effect in the prevention and control of public health pests, which can reduce the amount of pesticides Reduce the amount of application, save costs, and delay the emergence of pest resistance.

An insecticidal composition is disclosed that contains two active ingredients, which are transfluthrin and imiprothrin.
