Problems solved by technology

Although chemical control has the characteristics of high toxicity and quick effect, due to the unreasonable use of pesticides in the field for many years, Spodoptera litura has developed resistance to many pesticides, including avermectin with emamectin salt
[0004] The excessive use of pesticides will inevitably accelerate the development of pest resistance and bring severe challenges to pest control work. At the same time, pesticide residues caused by excessive use of pesticides will also easily lead to food safety problems

Embodiment 1

[0020] The bioassay of the present embodiment adopts the surface smear method;

[0021] Take 900 μL of artificial feed at around 70°C to the bottom of the 24-well culture plate, shake it slightly until the surface of the feed is flat, and there is no feed adhesion on the wall of the hole, and then let it dry and condense naturally;

[0022] A total of 7 concentration gradients of emamectin benzoate solution were set up, namely 0.02 μg / mL, 0.05 μg / mL, 0.1 μg / mL, 0.2 μg / mL, 0.5 μg / mL, 1.0 μg / mL, 2.0 μg / mL. The emamectin benzoin solution with different concentrations is obtained by diluting the emamectin emamectin mother liquor previously dissolved in acetone in corresponding proportions with pure water.

[0023] Take 50 μL of emamectin benzoin dilution solution of different concentrations and add it to the surface of the feed, treat two 24-well culture plates for each concentration, and dry them at room temperature for later use;

[0024] Then, add 50 μL of verapamil solution w...

Embodiment 2

[0034] Preparation of insecticide one:

[0035] 1) Dissolve emamectin emamectin with acetone, then add ultrapure water to make a dilution of emamectin emamectin with a concentration of 1.35 μg / mL;

[0036] 2) Take 50mL of the prepared emamectin benzoate dilution, add verapamil to it so that the mass ratio of emamectin benzoate to verapamil is 1:1, and make insecticide 1.

[0037] Preparation of insecticide two:

[0038] 1) Dissolving Abamectin with DMSO, then adding ultrapure water to make a concentration of 5.0 μg / mL Abamectin dilution;

[0039] 2) Get 50mL of prepared abamectin dilution, add verapamil to it to make the mass ratio of abamectin and verapamil be 1:5, make insecticide two.

[0040] Preparation of insecticide three:

[0041] 1) Dissolve emamectin emamectin with acetone, then add ultrapure water to make a dilution of emamectin emamectin with a concentration of 6.44 μg / mL;

[0042] 2) Take 50mL of the prepared emamectin benzoate dilution, add verapamil to it so...

Abstract

The invention relates to the field of insecticides and provides an insecticidal composition and application thereof. The insecticidal composition provided by the invention comprises an abamectin pesticide and a specific P-glycoprotein inhibitor, wherein the specific P-glycoprotein inhibitor is preferably verapamil. According to the invention, the insecticidal activity of the abamectin pesticide isenhanced, the usage amount of the field pesticide can be properly reduced, and the possible problem of pesticide residues is avoided; a synergist is environment-friendly and does not damage an ecological system; due to the use of the synergist, the sensitivity of prodenia litura to the abamectin pesticide can be remarkably improved; on the premise that poisoning effect is not changed, the use amount of the abamectin pesticide can be properly reduced; and the dosage of the insecticidal composition be saved, the pesticide effect of original insecticides can be improved, the pressure of the insecticidal composition to the environment can be reduced and the resistance of pests to the insecticidal composition can be delayed.

Description

technical field [0001] The invention relates to the field of insecticides, in particular to an insecticide composition and its application. Background technique [0002] Abamectin is a widely used agricultural or veterinary fungicide, insecticide and acaricide. Emamectin benzoate, full name emamectin benzoate, is a new type of high-efficiency semi-synthetic antibiotic insecticide synthesized from the fermentation product abamectin B1. It has ultra-high efficiency, low toxicity, low residue, Pollution-free and other characteristics of biological pesticides. It is widely used in the control of various pests on vegetables, fruit trees, cotton and other crops. Compared with abamectin, the insecticidal activity has been increased by 3 orders of magnitude, especially the activity against Lepidoptera and Diptera insects is extremely high, and it has both stomach toxicity and contact killing effect. [0003] Spodoptera litura, belonging to the genus Spodoptera litura of the famil...
