Embodiment 1

[0049] Embodiment 1 is to the bioassay test of storage pest

[0050] Targets to be tested: Eggs, larvae, pupae, and adults of A. chinensis, wheat moth. Sensitive strains were reared indoors.

[0051] Pharmacy preparation: Accurately weigh the active component A (A 1 : Pyroxyfen, A 2 : Pyriproxyfen, A 3 : Methoprene, A 4 : fenoxycarb) and B (B 1 : Chlorfluazuron, B 2 : Flufenuron, B 3 : Flufenuron), the original drug is made into a certain concentration of acetone stock solution.

[0052] Test on eggs: Cut the qualitative filter paper into a rectangular piece of paper with a size of 4 × 5cm, clamp the small filter paper piece with tweezers to make it hang in the air, take a certain amount of acetone solution of the target drug solution and drop it evenly on it with a pipette gun, wait until The acetone is completely volatilized and the filter paper block is placed in a petri dish. Use a fine brush under the microscope to dial the eggs into the filter paper block contain...

Embodiment 2

[0075] Embodiment 2 is to the bioassay test of hygienic pest

[0076] Targets to be tested: Culex 3-4 instar larvae and non-blood-sucking female mosquitoes 2-3 days after eclosion; Musca domestica 2-3 instar larvae and adults 4 days after eclosion, all sensitive strains reared indoors.

[0077] Pharmacy preparation: Accurately weigh the active component A (A 1 : Pyroxyfen, A 2 : Pyriproxyfen, A 3 : Methoprene, A 4 : fenoxycarb) and B (B 1 : Chlorfluazuron, B 2 : Flufenuron, B 3 : Flufenuron), the former drug is made into acetone stock solution, and is diluted with water containing 0.1% Tween 80 into a series of liquid medicines with a certain concentration gradient according to the test requirements.

[0078] Test method: For larvae, take normal maggot dry feed, test agent, distilled water, mix and stir evenly to form a feed containing certain active ingredients, and the effective concentration of each component is: A: 0.3mg / L; B: 0.3mg / L; A+B: 0.3+0.3mg / L. 50 larvae ...

Embodiment 3

[0087] Bioassays on agricultural and forestry pests Test targets: adults and nymphs of Mythimnaseperata, sensitive strains raised indoors; adult mites of Tetranychusurticae Koch, sensitive strains raised indoors.

[0088] Pharmacy preparation: Accurately weigh the active component A (A 1 : Pyroxyfen, A 2 : Pyriproxyfen, A 3 : Methoprene, A 4 : fenoxycarb) and B (B 1 : Chlorfluazuron, B 2 : Flufenuron, B 3 : Flufenuron), the former drug is made into acetone stock solution, and is diluted with water containing 0.1% Tween 80 into a series of liquid medicines with a certain concentration gradient according to the test requirements.

[0089] Test method: The spray method was used to measure the activity of the pear round scale. First, select apple leaves with neat pear round scales and nymphs, and each leaf can carry about 20 insects. Then spray evenly according to the order of the test design from low dose to high dose, 1.5mL per leaf, 3 repetitions for each treatment, and ...

Abstract

The invention provides a binary active component synergistic compounding composition and a preparation of the binary active component synergistic compounding composition. The binary active component synergistic compounding composition is prepared from a component A and a component B, wherein the component A is prepared from one of juvenile hormone insecticides, and the component B is prepared from one of chlorfluazuron, fluorobenzene or flucycloxuron. An insecticidal composition or the preparation is used for preventing termites and sanitary insect pests, and agricultural and forest pests, an insecticidal spectrum can be enlarged, the insecticidal efficiency is obviously superior to that of all single agents which are simply overlaid, and an obvious synergistic effect is obtained.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a synergistic compound composition containing juvenile hormone insecticides and chlorfluazuron, fenflufenuron or fenflubenzuron. Background technique [0002] Juvenile hormone insecticides mainly interfere with the hormone balance in insects, affect the physiological process of larvae turning into pupae or pupae eclosion into adults, form overage larvae or intermediates, and then control their growth and development. The main targets of this type of active substances are larvae and pupae, but they also have effects on mature insects and eggs, including preventing the embryonic development of insect eggs, increasing the number of molts of larvae, and causing infertility in adults. Juvenile hormone analogues were first used in the prevention and control of mosquito larvae in water swamps. With the development of its application, the scope of use has become wider and wider. It can ...
