Novel insecticide finishing liquid for treating mosquito-repellent fabrics and use method thereof

Abstract

The invention provides a novel insecticide finishing liquid for treating mosquito repellent fabrics. The novel insecticide finishing liquid is innovatively added with a novel insecticide chlorfenapyr, wherein the chlorfenapyr belongs to pyrrole insecticides. The chlorfenapyr is mainly used for preventing and treating termites and various pests of crops, destroys the oxidation pathway in insect mitochondria in a targeted manner so as to destroy ATP generation to play a role, and has no cross resistance with the existing public health insecticide; and due to the novel action mode, the chlorfenapyr becomes an appropriate candidate insecticide for malaria media resistant to various medicines, and a mixture of chlorfenapyr and alpha-cypermethrin on a mosquito net is proved to have irritant repelling and strong insecticidal activity on mosquitoes resistant to pyrethroid.

Description

technical field [0001] The invention relates to the field of hygienic insecticides, in particular to a novel insecticide finishing solution for treating mosquito repellent fabrics and a method of use. Background technique [0002] Malaria is an infectious disease caused by Plasmodium parasites in the human body. It is infected by the bite of Anopheles mosquitoes or the blood of people with Plasmodium. Malaria caused by Plasmodium is one of the main causes of human death in the world. According to the "World Malaria Report" published by WHO in 2018: in 2017, there were an estimated 219 million cases of malaria worldwide, compared with 239 million cases in 2010 and 217 million cases in 2016). Most malaria cases in 2017 occurred in the WHO African Region (200 million or 92%), followed by the WHO South-East Asia Region (5%) and the WHO Eastern Mediterranean Region (2%). Between 2010 and 2017, Global malaria incidence has declined, from 72 to 59 cases per 1,000 at-risk populatio...

AI Technical Summary

Problems solved by technology

[0005] At present, as insecticides for long-acting anti-mosquito nets, pyrethroids are one of the main compounds. Using this kind of insecticide alone has the disadvantage of high toxicity, and with the use of this organically synthesized insecticide As the use time increases, mosquitoes and flies have produced different degrees of resistance to this class of insecticides (Gao Xiwu et al., Chinese Journal of Vector Biology and Control, 2004, 15(2), 105)

[0006] Disclosed in Chinese patent (publication number CN 1099825) is a kind of anti-mosquito, mosquito-killing, bactericidal fabric finishing liquid, has added synergist in the formula, is made up of mosquito repellent, mosquito-killing agent, bactericide, synergist etc. After the liquid is soaked and dried, the obtained fabric has the functions of anti-mosquito, mosquito-killing, and bactericidal. However, this formula is used as a mosquito repellent finishing liquid, and the duration of the drug effect is only half a year, which has the disadvantage of a short duration of drug effect.

[0007] A Chinese patent (publication number CN 1664227A) discloses a fabric finishing solution for repelling and killing mosquitoes. It has strong ability to repel mosquitoes and is washable, but as the use time increases, mosquitoes will develop resistance to the insecticide pyrethroids in the fabric finishing solution

However, the patent does not introduce what kind of process to use to make the insecticide evenly distributed in each position of the insecticide material

Just using impregnation will make the distribution of insecticide in the insecticidal material uneven, resulting in ineffective insecticidal effect

[0009] That is to say, in the prior art, the use of a single pyrethroid insecticide will lead to an increase in the resistance of mosquitoes, and the mosquito-killing fabrics made cannot be washed and used for a long time, the duration of effect is short, and the washing-resistant effect is not good.

At the same time, due to poor technology, it is easy to cause uneven distribution of insecticides, and the best biological efficacy cannot be achieved.
