CN-121986782-A - Diptera adult pesticide

Abstract

An insecticide for adult diptera contains n-butanol as insecticidal component. The invention separates n-butanol with obvious poisoning effect on pumpkin fruit fly adults from bacillus thuringiensis Bacillus thuringiensis XLB2910 strain metabolite, and also separates 2,3, 5-trimethyl pyrazine and benzothiazole with obvious poisoning effect on aedes albopictus adults. Through the poisoning concentration analysis and the compound combination experiment of different components, a series of pesticide for the adult pumpkin fly and the adult aedes albopictus is formed, the prepared pesticide for the compound pumpkin fly comprises 2.5-10% of2, 3, 5-trimethyl pyrazine, 2-10% of benzothiazole and 5-10% of n-butyl alcohol, and the prepared pesticide for the compound aedes albopictus comprises 0.5-3% of2, 3, 5-trimethyl pyrazine, 0.05-1.5% of benzothiazole and 1-3% of n-butyl alcohol. The compound pesticide has good insecticidal effect on pumpkin fruit fly adults and Aedes albopictus adults, and has wide raw material sources and environmental friendliness.

Description

Diptera adult pesticide Technical Field The invention relates to a technology for preventing and controlling diptera adults, in particular to a diptera adult pesticide. Background At present, chemical control is still a core means for controlling adults of diptera pests such as pumpkin fruit fly, aedes albopictus and the like in the fields of agricultural production and public health. However, this area is faced with a profound contradiction between technical bottlenecks and market demands. On one hand, the pest breeding is rapid, the adaptability is strong, the control means are required to be efficient and rapid, and on the other hand, the long-term dependence on chemical pesticides has caused serious drug resistance problem and causes the worry of environmental pollution and non-target biological injury. Therefore, the core pain of industry development is how to remarkably reduce the resistance risk, the application frequency and the negative environmental impact while ensuring the efficient prevention and control, and the development of the next-generation green control technology with the combination of effectiveness, safety and sustainability is urgent. Aiming at pumpkin fruit flies seriously harming melons and fruits, the current control method mainly focuses on the adult stage, and adopts food attractant (such as hydrolyzed protein mixed insecticide) or sex pheromone (such as methyl eugenol) for trapping and killing. However, the methods have the obvious defects that firstly, the trapping and killing effect is greatly influenced by environmental factors (such as rainfall and sun exposure), active ingredients in liquid medicine or trapping cores are easy to decompose and volatilize, the duration is short, frequent supplementation is needed, the labor cost is high, secondly, sex trapping and killing is mainly aimed at male insects, the overall compacting effect on the population is limited, and furthermore, the larvae are hidden in fruits and have narrow control window period. These defects lead to a low control efficiency. Spraying contact killing of adult fruit flies is an efficient prevention and control strategy, but chemical pesticides such as phoxim, cypermethrin and the like are mainly relied at present, and the potential risk of inducing pest resistance exists due to long-term use of a single action mechanism medicament. In the public health field, aedes albopictus is an important transmission medium for dengue fever, epidemic encephalitis B and chikungunya fever diseases, and currently, space spraying or hedge spraying is mainly carried out on chemical pesticides such as pyrethroids (e.g. deltamethrin and cypermethrin), organic phosphors (e.g. fenitrothion and methyl pyrimidyl phosphate) and the like. Due to the long-term large-scale use of mainstream chemicals, many regional mosquito groups have developed high levels of resistance to mainstream chemicals, resulting in dramatic drop in efficacy, which has led to prevention work in a "poorly effective-dose-higher-resistant" vicious circle, which is highly desirable for innovation. It has been reported that the volatile compounds of microorganisms have poisoning effect on pests, but the poisoning effect of the volatile compounds derived from Bacillus thuringiensis on diptera adults has not been reported yet. Disclosure of Invention The first technical problem to be solved by the invention is to provide the diptera adult pesticide which has good killing effect and is safe to use. The second technical problem to be solved by the invention is to provide the pumpkin fly insecticide. The third technical problem to be solved by the invention is to provide the pumpkin fly compound pesticide. The fourth technical problem to be solved by the invention is to provide the aedes albopictus insecticide. The fifth technical problem to be solved by the invention is to provide the aedes albopictus compound pesticide. The invention solves the first technical problem by adopting a technical scheme that the diptera imago insecticide contains n-butanol which is an insecticidal efficacy component. Further, the diptera adult is a pumpkin fruit fly adult or an aedes albopictus adult. The pesticide provided by the invention also has a good poisoning effect on fruit flies such as citrus fruit flies and the like. The invention solves the second technical problem by adopting a technical scheme that the pumpkin fruit fly pesticide is characterized in that the pesticide has an insecticidal efficacy component of n-butyl alcohol, and the concentration of the n-butyl alcohol is 5-15% by volume percent. Preferably, the concentration of the n-butanol is 8% -11%. Further, the pumpkin fly is a ten-day-old sexual mature adult. The invention solves the third technical problem by adopting a technical scheme that the pumpkin fruit fly compound pesticide comprises, by volume, 5-10% of n-butanol, 2.5-10% of 2,3, 5-trimethyl pyrazine, 2-10% of benzothiazole and the balance of solvent.
