Sanitation insecticidal composition containing alpha-cypermethrin and application thereof

Abstract

The invention relates to a sanitation insecticidal composition containing alpha-cypermethrin and application thereof. Compared with a single agent, the composition has an unexpected synergistic effect, the insecticidal effect is improved, the synergistic coefficient is 130 or above, and particularly, the composition has excellent knockdown and killing effects on sanitation pests with resistance topyrethroid; besides, a compound preparation of the composition has an excellent control effect on Culex pipiens pallens, and compared with a conventional alpha-cyan-containing pyrethroid related preparation, the compound preparation is low in toxicity, odorless and low in irritation, and is very suitable for indoor and outdoor sanitation pest control.

Description

technical field [0001] The invention relates to the field of hygienic insecticides, in particular to a hygienic insecticide composition containing cis-cypermethrin and its application. Background technique [0002] Neonicotinoid insecticides are derived from the plant pesticide nicotine, and were used for Homoptera pests in 1980. Until the 1980s, Bayers developed a series of chlorinated nicotine insecticides. This is the first The second generation of neonicotinoid insecticides, imidacloprid is the first insecticide researched and developed. Unlike conventional insecticides, neonicotinoid insecticides have no mutual resistance. The new neonicotinoid insecticides have obvious systemic effect on the roots, high insecticidal activity and wide insecticidal range, especially highly effective against Homoptera, Coleoptera and some Lepidoptera pests, and have low toxicity to mammals. It can be used not only for stem and leaf treatment, but also for seed treatment, so it has attrac...

Problems solved by technology

Although neonicotinoid insecticides have both stomach toxicity and contact activity, their stomach toxicity activity is significantly higher than that of contact activity, so they are mainly used for stomach poisoning to kill pests with piercing-sucking mouthparts or chewing mouthparts; and Sanitation insecticides are mainly used to control mosquitoes and flies, such as space spray or lingering spray, and the mode of action is contact killing, and the stomach poisoning activity is difficult to play a role, which limits the application of neonicotinoid insecticides in sanitation insecticides

For example, Chinese patent CN201010298607.4 discloses a compound composition of dinotefuran and cis-cypermethrin and other pyrethrin active ingredients. However, on the one hand, this combination only focuses on field pests, such as aphids, whiteflies, etc., and does not pay attention to The application of sanitary pests, and in terms of specific data, only involves the synergistic effect of dinotefuran and beta-cypermethrin, and does not involve the synergistic effect of combining with cis-cypermethrin, which is a new generation of permethrin different from beta-cypermethrin class product

[0004] The applicant found through a large number of drug efficacy tests that although there are many types of neonicotinoid insecticides, only thiacloprid, thiamethoxam, clothianidin, chlorothiazolin, and sulfoxaflor are effective against diptera mosquitoes and flies. It has relatively efficient contact killing activity, dinotefuran, nitenpyram, imidacloprid, and acetamiprid have poor activity, especially thiamethoxam, clothianidin, and chlorothiamid It has the best activity with thiacloprid, very suitable for space spray or residual spray for the control of sanitary pests, mosquitoes and flies

[0005] Although the neonicotinoid insecticides used to control mosquitoes and flies have excellent contact killing activity, the control of hygienic pests needs to be quick-acting. not available
