Description

Technical Field

[0001] The present invention relates to a sanitary insecticide bait composition containing a piperic acid derivative compound (compound I-72), wherein the effective ingredient is a combination of a piperic acid derivative compound (compound I-72 for short) and a compound selected from the group consisting of fipronil, indoxacarb, dinotefuran, hydrazone and imidacloprid. Background Art

[0002] As people's living standards continue to improve, they have higher requirements for their living environment. Cockroaches, ants, and red fire ants are pests that have long caused trouble and harm to residents' lives. The financial resources invested in disinfecting these pests are increasing year by year. At present, the most important product in pest control is bait. Since cockroaches, ants, and red fire ants are difficult to kill completely, the applicators can only kill the insects by increasing the dosage and frequency of application. This has led to a significant increase in drug resistance, an increase in the cost of application, and an increase in the workload of the applicators. Therefore, the market is in urgent need of a new generation of baits to alleviate the plight of the pest control market.

[0003] Fipronil is a phenylpyrazole insecticide with a broad insecticide spectrum. It is mainly a stomach poison, and has both contact and systemic effects. Its mechanism of action is to act on the γ-aminobutyric acid (GABA) receptors in the insect central nervous system to block the opening of cellular chloride ion channels, interfere with the central nervous system, and cause the insect's nerves and muscles to be overexcited and die.

[0004] Indoxacarb is a broad-spectrum oxadiazine insecticide that blocks the sodium ion channels in insect nerve cells, causing the nerve cells to lose their normal function and die. It has stomach poison and contact killing effects.

[0005] Imidacloprid is a first-generation neonicotinoid compound, an acetylcholine receptor stimulant. It binds to acetylcholine receptors, destroys the central nervous conduction of pests, causing the pests to be excited and die. It has contact, stomach poison and systemic effects.

[0006] Dinotefuran is a third-generation neonicotinoid compound, an acetylcholine receptor stimulant, with a broad insecticide spectrum and contact, stomach poison and systemic effects. Compared with traditional neonicotinoid insecticides, it has higher insecticidal activity and higher systemic and permeation activity.

[0007] Hydrahydrazone mainly acts on the mitochondria in insects, causing metabolic system disorders and respiratory system failure in the pests, and eventually death from flaccid paralysis.

[0008] As a new type of insecticide, the piperic acid derivative compound (Compound I-72) is a derivative of the piperic acid compound, which has a good killing effect on cockroaches, ants, and red fire ants. The piperic acid derivative compound (Compound I-72) is compounded with one of fipronil, indoxacarb, dinotefuran, hydrazone, and imidacloprid to solve the problem that resistant varieties of pests are difficult to disinfect. On the one hand, the two have different mechanisms of action, and there is no cross-resistance when combined, which can solve the resistance problem of sanitary pests to fipronil, indoxacarb, dinotefuran, hydrazone, and imidacloprid; on the other hand, through research, it is found that the combination of the two can improve the control effect of sanitary pests, and it is a compound drug technology with good market prospects.

[0075] Application Example 1 Co-toxicity Coefficient Determination

[0076] Test basis: Refer to NY / T1154.7-2006 "Guidelines for Indoor Bioassay of Pesticides - Insecticides Part 7: Determination of Combined Effects of Mixtures" for test insects;

[0077] Test target: German cockroaches, 10- to 15-day-old adults, half male and half female.

[0078] Test conditions: temperature 25℃±1℃, relative humidity 65%±5%

[0079] Drugs to be tested:

[0080] 90% piperic acid derivatives (Compound I-72) (Shenyang Sinochem Pesticide Chemical Research and Development Co., Ltd.)

[0081] 95% Fipronil (Jiangsu Youjia Plant Protection Co., Ltd.)

[0082] 70.5% Indoxacarb (Jiangsu Youjia Plant Protection Co., Ltd.)

[0083] 98% Dinotefuran (Hubei Shenglong Chemical Co., Ltd.)

[0084] 95% hydrazone (Jiangsu Youjia Plant Protection Co., Ltd.)

[0085] 98% Imidacloprid (Jiangsu Youjia Plant Protection Co., Ltd.)

[0086] Test method:

[0087] Take the test agent and dissolve it in dichloromethane first, then use an aqueous solution containing 0.1% Triton-X100 to make a series of dilutions at a ratio of 1:9. Take 1mL of each diluted concentration and add it to a 150mL serum bottle. Keep turning the serum bottle to make the solution evenly distributed on the inner wall of the bottle. Put it in a fume hood overnight to make the organic solvent evaporate completely. Put the test insects to determine the concentration range of 100% death and 100% survival. Take the appropriate concentration in this range and use an aqueous solution containing 0.1% Triton-X100 to make a series of multiple dilutions. Take 1mL of each diluted concentration and add it to a 150mL serum bottle. Keep turning the serum bottle to make the solution evenly distributed on the inner wall of the bottle. Put it in a fume hood overnight to make the organic solvent evaporate completely. Then apply vaseline on the bottleneck of the serum bottle, put 20 test insects in each bottle, and repeat the experiment 5 times. The corresponding solvent treatment is the control group. After 1h, all test insects are transferred to a clean vessel for standard feeding, and the number of deaths is checked and counted after 72h.

[0088] The statistical analysis software SPSS was used to analyze and calculate the LC50 of each drug and its 95% confidence limit. The co-toxicity coefficient of the mixture was calculated as follows:

[0089]

[0090] In the formula

[0091] LC50A--the lethal concentration of agent A

[0092] LC50B--lethal concentration of agent B

[0093] LC50 mixture - the lethal concentration of a mixture of agent A and agent B

[0094] PA--the proportion of agent A in the active ingredients of the mixture

[0095] PB--the proportion of agent B in the active ingredients of the mixture

[0096] A co-toxicity coefficient greater than 120 indicates a synergistic effect, a co-toxicity coefficient between 80-120 indicates an additive effect, and a co-toxicity coefficient less than 80 indicates an antagonistic effect. The test results are shown in the following table
