Problems solved by technology

Its mechanism of action is still not completely clear. Most people believe that the mechanism of action of this type of compound is mainly to open the sodium ion channel for a long time, which eventually leads to excessive excitement of the pest, causing it to lose control, and finally the nerve conduction is completely blocked, resulting in paralysis and death.

Embodiment 1

[0042] Embodiment 1——to agricultural pest (bemisia tabaci, spider mite) efficacy evaluation test

[0043] Bemisia tabaci is an insect of the order Homoptera with a wide range of hosts. The loss of cotton, eggplant, cucumber, tomato, zucchini and cabbage can reach more than 80%, and when the damage is serious, it can cause crop failure. In recent years, cabbage has been severely damaged by Bemisia tabaci, which not only affects the yield, but also affects the quality. The body of whitefly is waxy, the generations overlap, the reproduction speed is fast, and resistance is easy to develop. Therefore, it is urgent to screen new insecticides so that they can quickly prevent and control whitefly damage, are not easy to develop resistance, and are safe and low-residue. . Spider mite, scientific name spider mite, takes about three weeks from egg to adult, and feeds on the leaves and fruits of indoor plants and important agricultural plants. Its resistance to drugs is increasing day ...

Embodiment 2

[0055] Example 2—Evaluation Test of Sanitation Pest Control Efficacy

[0056] D-trans permethrin, with high vapor pressure, has a high knockdown and lethal effect on sanitary pests, and its drug effect is 10 to 15 times that of tetramethrin. There is a good market prospect. D-phenothrin has strong contact power, stomach toxicity and residual effect, and is suitable for preventing and controlling flies, mosquitoes, cockroaches and other sanitary pests in households, public places and industrial areas. Cyfluthrin is an inhalation and contact insecticide with excellent knockdown and killing activity against mosquitoes, flies and other sanitary pests.

[0057] The test method takes dextro-trans permethrin to control Anopheles sinensis as an example. The full-fledged Anopheles sinensis is raised in a single tube in the mosquito breeding room for 7 days. Group A adds dextro-trans permethrin to clean water Group B added methoprene in clear water, group C added methoprene and D-tran...

Embodiment 3

[0062] Example 3 - Evaluation of Efficacy in Treating Parasitic Infections in Dogs

[0063]The test method took cis-cyhalothrin as an example to control lice, and 12 dogs that were identified as being infected by parasites (lice and mite) were randomly divided into 4 groups, and group A was treated with a composition containing cis-cyhalothrin For treatment, group B was treated with a composition containing methoprene, group C was treated with a composition containing methoprene and cis-cyhalothrin, and group D was not treated. Attach a piece of test paper to the inside of the dog’s limbs, set the dead lice parasites to stick to the test paper, and count the number of deaths to compare with group D, so as to determine the reduction of pests, and the observation time is 24 Days were observed on the 1st, 6th, 12th, 18th, and 24th day after treatment. Table 5 is the test results at 24 days.

Abstract

The invention provides a safe, environment-friendly and efficient insecticidal composition, which comprises methoprene and at least one pyrethroid insecticide. The two insecticides have different modes of action, and through the synergistic effect of the two, the insecticidal composition can play an insecticidal role more quickly and more completely, effectively controls different insect body shapes at various stages in the whole life cycle of pests, at the same time also reduces the frequency of drug administration by farmers, lowers the pharmacy cost, and delays the generation of resistance.

Description

technical field [0001] The present invention relates to a kind of safe, environment-friendly, high-efficiency insecticidal composition, more specifically, the present invention relates to the composition of methoprene and one or more pyrethroid insecticides, for controlling agricultural pests, Controls sanitary pests, treats parasitic infestation of animals and kills storage pests. Background technique [0002] Methoprene was registered for use in Canada as early as 1977, and the United States and the World Health Organization even characterized the drug as an actual non-toxic pesticide with high efficacy. Its chemical name is 2E, 4E-11-methoxy-3,7,11-trimethyl-dodecadienoic acid isopropyl ester (Isopropyl(2E,4E)-11-methoxy-3,7,11 -trimethyl1-2, 4-dodecadienoate), is one of the important insect growth regulators (IGRs), which belongs to insect juvenile hormone analogues. Its main function is to control the growth and development of pests, so that larvae cannot change into ...
