Description
Technical Field
The invention relates to the technical field of pest control, in particular to a trapping device with a compound insect sex pheromone lure core and application thereof.
Background
Insect pheromones are a generic term for compounds used to communicate between insects, and are the chemical molecular languages used to communicate between insects. Pheromones can be divided into different categories and can cause certain behavioral responses of other individuals, including functions of mating, spawning, aggregation, alarming and the like. Among them, pheromones used for attracting mating between males and females of the same species are called sex pheromones (also called sex pheromones), which have high specificity and sensitivity.
The traditional plant pest control is mainly carried out by chemical pesticide, and although the chemical pesticide has the advantages of high pesticide effect and easy large-scale spraying application, the chemical pesticide has large toxic and side effects of environmental pollution and ecological damage, and is easy to generate insect drug resistance to cause great reduction of the pesticide effect. The female insects release sex pheromone after sexual maturity, attract the same kind of male insects to mate with the female insects specifically, and propagate offspring. The artificial synthetic sex pheromone of the pests is released in the control area to attract the males to the special trap, so that the mating times of the males and the females can be greatly reduced, the population quantity of the progeny of the pests is reduced, and the control purpose is achieved. Therefore, a green biochemical control method for trapping and controlling pests using insect sex pheromones is gradually studied and applied.
Prior patent 1: the application publication number CN103070170B discloses a composite attractant for attracting female and male rice leaf rollers and application thereof, wherein the composite attractant consists of trans-2-hexenal and sex pheromone of the rice leaf rollers; the proportion of trans-2-hexenal to the sex pheromone of the cnaphalocrocis medinalis is 100-1000 ug: 1 ug; the sex pheromone of the rice leaf roller is a mixture of cis 11-octadecenal, cis 13-octadecenal, cis 11-octadecenol and cis 13-octadecenol, and the proportion of the components is 60 ug: 500 ug: 60 ug: 120 ug.
Prior patent 2: chinese patent with publication number CN207692796U discloses an insect killing lamp, which comprises a base and a pillar arranged at the upper end of the base, wherein an insect trapping lamp tube is arranged at the center of the upper end of the base, an electric network and a protective net are annularly arranged on the periphery of the insect trapping lamp tube, an electric box electrically connected with the electric network and the insect trapping lamp tube is arranged at the upper end of the pillar, and a waterproof cap is arranged at the upper end of the electric box; the lower end of the base is provided with a collecting device for collecting pests.
Although the technical scheme of the prior patent 1 improves the quantity of the rice leaf roller female moths reaching the information source by enhancing the reaction of the antennal potential (EAG) of the male moths and the female moths of the rice leaf roller to the sex pheromone, in the actual use process, because the rice insect pests also comprise the sesamia inferens and the chilo suppressalis besides the rice leaf roller, a single rice pest sex attractant cannot prevent and control various insect pests of rice in a larger range, and the prevention and control effect is lower;
although the technical scheme of the prior patent 2 realizes the effect of trapping phototaxis pests by matching the trap lamp and the power grid, the single light source trapping is not sufficient in specificity of trapping pests and is not suitable for large-scale prevention and control of rice field pests. Therefore, there is a need to improve the specificity and efficiency of insect sex pheromones in pest control in rice fields.
Disclosure of Invention
