Problems solved by technology

[0003] Long-term use of pesticides will cause cotton aphids to develop resistance, and simply increasing the use of pesticides will pollute the environment
However, with the frequent use of neonicotinoid insecticides in recent years, the resistance of cotton aphids to these insecticides has become increasingly serious.

experiment example 1

[0021] In this experiment, aproteril and imidacloprid were used as the test agents, and the toxicity of the leaf film method was used to determine the toxicity of the single agent and the mixture of various proportions. The toxicity of the leaf film method was used to calculate the LC 50 , co-toxicity coefficient (CTC) and optimal ratio.

[0022] 1. Research object

[0023] Laboratory-reared multigenerational field populations of cotton aphids. The field population of cotton aphids was collected from cotton fields in Xinjiang, and non-transgenic cotton seedlings were cultivated indoors for multiple generations.

[0024] 2. Method

[0025] For the test agents diproteril and imidacloprid, the indoor toxicity test was carried out by using the leaf drug film method, including the single agent toxicity test of dipropetrin and imidacloprid; force measurement. Calculate the virulence assay results and calculate the LC 50 , Co-toxicity coefficient (CTC) to get the best ratio.

Abstract

The invention relates to compound insecticide for effectively preventing and controlling cotton aphids. Aiming at solving the technical difficulties of the drug resistance of the cotton aphids, the invention finds out that afidopyropen and imidacloprid are compounded and can be used for effectively delaying the drug resistance of the cotton aphids on the basis of a lot of indoor toxicity screening; the compound insecticide has a synergetic effect on prevention and control of the cotton aphids and a novel effective prevention and control means is provided for insect pest comprehensive treatmentof the cotton aphids. According to the compound insecticide provided by the invention, the dosage of pesticide is reduced, so that the cost is reduced and pollution to the environment is reduced; theresistance management of the cotton aphids is facilitated and popularization and application have great economic benefits and social benefits.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a compound insecticide for effectively preventing and controlling cotton aphids. Background technique [0002] Cotton aphids (Aphis gossypii Glover) is an important pest worldwide, which can feed on more than 700 kinds of plants including cotton and cucumber. Cotton aphids cause harm mainly by directly feeding on plant sap and spreading plant viruses, causing huge economic losses to agricultural production. Cotton aphid has the characteristics of fast reproduction, large population, and severe damage. For a long time, chemical control has been the main means of control of cotton aphid in my country. Due to the long-term and extensive use of chemical pesticides, cotton aphids have developed high levels of resistance to various insecticides such as organophosphates, carbamates, pyrethroids, and neonicotinoids. [0003] Long-term use of pesticides will lead to resis...
