Insecticide composition for controlling stored grain pest population

Abstract

The invention discloses an insecticide composition for controlling the stored grain pest population. The insecticide composition comprises active components of illicium verum essential oil, deltamethrin and methoprene. The mass ratio of the illicium verum essential oil to the deltamethrin to the methoprene is 1:(1-4):(4-20). The application amount of the illicium verum essential oil in stored grain is larger than or equal to 0.25 mg / kg, the application amount of the deltamethrin in the stored grain is 0.25-1 mg / kg, and the application amount of the methoprene in the stored grain is 1-5 mg / kg.According to the insecticide composition, based on the characteristics of the three kinds of pesticides of the methoprene, the deltamethrin and the illicium verum essential oil in prevention and treatment of stored grain pests, the advantages of the three kinds of pesticides are sufficiently used, the defects of the three kinds of pesticides are overcome, the three kinds of pesticides are scientifically and reasonably combined, and the insecticide composition has a synergistic function and is used for prevention and treatment for the stored grain pests; particularly for controlling the population of coleoptera and lepidoptera stored grain pests such as tribolium castaneum, the insecticide composition has a good fast-acting property, the aim of controlling pest dangers for a long time can also be achieved, and the insecticide composition is safe and free of pollution and has important application popularization value.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to an insecticide composition for controlling stored grain pest populations. Background technique [0002] Methoprene is a juvenile hormone insect growth regulator developed by the United States in the 1970s. As an insecticide registered as a biochemical pesticide, methoprene can control the growth and development of pests, causing abnormal development and death of pests. Methoprene has a wide insecticidal spectrum and is effective against various insects including Lepidoptera, Diptera, Coleoptera, Homoptera, etc. To increase the silk production of silkworm. Methoprene is a green and pollution-free insecticide with low or no toxicity to higher animals. It has been evaluated by the Food and Agriculture Organization of the United Nations and the World Trade Organization as a pesticide that is harmless to public health. The United States also stipulates that it should b...

AI Technical Summary

Problems solved by technology

Although methoprene can well control the next generation population of pests and has a long drug effect period, it has no control effect on contemporary larvae, thus causing serious damage to stored grains from contemporary larvae

Although deltamethrin and star anise essential oil have a good control effect on the contemporary larvae, they are poor in controlling the population of the next generation of pests, resulting in a large number of next generation pests. The final result is that the efficacy period is short and multiple applications are required. Medicines can effectively control the harm of pests

[0006] Currently, there is no report on the combination of deltamethrin and methoprene, or the combination of star anise essential oil, deltamethrin and methoprene
