Description

High-efficiency chlorofluorocyanide insecticidal composition of pyrethrin

Technical Field

The invention belongs to the technical field of pesticides, and particularly relates to an application of an insecticidal composition containing high-efficiency cyhalothrin in diptera pests.

Background

The pyrethroid (pyremroids, PY) pesticide has the characteristics of high efficiency, wide application range, strong stability and relatively low toxicity, gradually replaces organic chlorine and other highly toxic and long-residual pesticides, and is widely applied to agricultural, forestry and residential pest control. Pyrethroid insecticides grow fastest among four major types of insecticides, and the pyrethroid has the problems of easy resistance, high fish toxicity, low systemic property and the like when being widely used.

Cyhalothrin is a sodium ion channel regulator and acts on the nervous system of insects. Can keep the sodium ion channel smooth, and cause insect hyperexcitation. In some cases, nerve conduction block (sodium channels participate in the conduction of action potentials along nerve axons) is also caused.

Flupyroxystrobin is a methoxy acrylic acid ester pesticide, the CAS number is 114077-75-7, and the chemical structural formula is:

The application carries out the drug effect test on the diptera pests by the Flupyroxystrobin and the high-efficiency cyhalothrin compound agent, improves the quick acting property of the high-efficiency cyhalothrin on the diptera pests, reduces the control cost and opens the way for controlling the diptera pests.

And (3) medicament treatment, namely selecting a test tube with the diameter of 15 multiplied by 150mm, adding 0.5mL of medicament liquid into the test tube by using a liquid transfer device, fully rolling the test tube until the medicament liquid is dried.

Each tube was inoculated with 20 male and female adults (male: male = l: 1) with initial emergence, sealed with white gauze, treated with acetone as a control, and each treatment was repeated 4 times.

And (3) data investigation, namely checking the death number after 4 hours, and calculating and obtaining a virulence regression formula and LC ₅₀.

Data statistics and analysis show that the death rate of the blank control is less than 5% without correction, the death rate of the blank control is 5% -10%, the death rate of the blank control is required to be corrected, and the test is required to be carried out again when the death rate of the blank control is more than 10%.

The calculation formula is as follows:

Mixed agent theoretical toxicity index tti=ti _A×P_A+TI_B×P_B

Co-toxicity coefficient

Wherein P _A、P_B is the proportion of the active ingredient A, B in the composition.

Co-toxicity coefficient (CTC):

CTC <80 is antagonism, CTC >120 is potentiation, and 80< CTC <120 is additive.
