Problems solved by technology

[0002] For a long time, the pesticides used to prevent and control sanitary pests are all pyrethroids. The long-term use and single use method of pyrethroids have greatly increased the resistance of sanitary pests such as cockroaches, hygienic mosquitoes and hygienic flies to pyrethroids. In recent years, there has been a general decline in the control effect

Embodiment 2

[0040] Add 100 biomass parts of water to the mixture of 100 parts by weight of wood carbon powder, cornstarch and coconut shell powder (5: 1: 4) and knead it into shape, then dry to form incense stick-like disc insecticidal substrate ( The diameter is 14cm, the thickness is 4mm, and the pair weighs 34g).

[0041] On the other hand, 0.4 parts by weight of D-enriched trans-allethrin was dissolved in vegetable oil to obtain a 0.4 w / v% D-enriched-trans-allethrin solution.

[0042] Use a micro-syringe to draw 3.4ml of the above mixed solution and evenly drop it on the above disc-type mosquito-repellent incense insecticidal base material, then place it at room temperature for 5 hours to obtain a set of discs with 0.04w / w% rich D-trans allethrin Mosquito coil III.

Embodiment 3

[0044] Add 100 biomass parts of water to the mixture of 100 parts by weight of wood carbon powder, cornstarch and coconut shell powder (5: 1: 4) and knead it into shape, then dry to form incense stick-like disc insecticidal substrate ( The diameter is 14cm, the thickness is 4mm, and the pair weighs 34g).

[0045] On the other hand, 0.32 parts by weight of perfluthrin and 0.18 parts by weight of rich dextro-trans allethrin are dissolved in vegetable oil to obtain 0.22w / v% of perfluthrin and rich dextro-trans allethrin. Trans-allethrin 0.18w / v% mixed solution.

[0046] Use a micro-syringe to draw 3.4ml of the above mixed solution and evenly drop it on the above disc-type mosquito-repellent incense insecticidal base material, then place it at room temperature for 5 hours to obtain a set with 0.022w / w% perflumethrin, 0.018w / w % Enriched D-trans allethrin coil type mosquito coil Ⅳ.

Embodiment 7

[0086] Adopt the pulp electric mosquito sheet porous base material of 35mm * wide 22mm * thick 2.8mm specification, the ethanol that will contain 2.8 parts by weight of perfluthrin and 7.2 parts by weight is mixed together to prepare insecticidal composition insecticidal solution, Take 10 mg of the obtained solution and evenly drop it on the porous substrate of the electric mosquito sheet, dry it and leave it for 5 hours to obtain an insecticidal electric mosquito-repellent sheet II, which contains 2.8 mg of perflumethrin.

[0087] Reference Example 8

[0088] Adopt the pulp electric mosquito sheet porous base material of 35mm X width 22mm X thickness 2.8mm, mix the ethanol containing 2.8 parts by weight of difenoxacarb and 7.2 parts by weight together to prepare the insecticidal composition insecticidal solution, take 10mg to get The solution was evenly added dropwise on the porous substrate of the electric mosquito repellant, dried and left for 5 hours to obtain an insectici...

Abstract

The invention relates to a composition containing tetrafluoro ethofenprox and malathion and application thereof. The composition is used for controlling sanitary pests such as sanitary mosquitoes, sanitary flies, Groton bugs and red imported fire ants, wherein the mass ratio of the tetrafluoro ethofenprox to the malathion is 1:99-99:1. The two pesticides contained in the composition have different toxicology and independently achieve effects; during preparation, the two pesticides have synergy to improve the effect of controlling the sanitary pests; the medicaments are mutually combined in vivo of pests, so each development stage in the whole life history of the sanitary pests can be controlled; and products such as mosquito coils, electrical mosquito mats and baits prepared from the pesticidal composition have the advantages of quick pest killing, and long pesticide effect, and can ideally control the sanitary pests with resistance to pyrethroid insecticides.

Description

technical field [0001] The invention relates to an insecticidal composition, in particular to a hygienic, environment-friendly and efficient insecticidal composition for preventing and controlling hygienic pests. In particular an insecticidal composition comprising perfluthrin and malathion. Background technique [0002] For a long time, the pesticides used to prevent and control sanitary pests are all pyrethroids. The long-term use and single use method of pyrethroids have greatly increased the resistance of sanitary pests such as cockroaches, hygienic mosquitoes and hygienic flies to pyrethroids. In recent years, there has been a general decrease in the control effect. Therefore, an environmentally friendly and efficient new pesticide variety or pesticide compound variety is needed to delay the emergence of resistance to sanitary pests. The development of new pesticides is not only time-consuming and laborious, but the compounding of two pesticides can not only maximize t...
