Embodiment 1

[0023] Example 1 The indoor toxicity determination of thiamethoxam and pyriproxyfen in different proportions to larvae

[0024] Through a large number of indoor screening tests, it was found that the combination of thiamethoxam and pyriproxyfen had an obvious synergistic effect on larvae. The specific tests are as follows:

[0025] Test drug: 98% thiamethoxam technical (Syngenta (Suzhou) Crop Protection Co., Ltd.); 95% pyriproxyfen technical (Shanghai Shengnong Biochemical Products Co., Ltd.).

[0026] Test objects: larvae of Anopheles sinensis and Culex pipiens pallens, both provided by the Guangdong Provincial Institute of Entomology.

[0027] Test method: Dissolve the sample in DMF, dilute with 0.1% Tween 80 aqueous solution, make 200 mg / L single-dose mother liquid of thiamethoxam and pyriproxyfen respectively, and then prepare different single-dose concentrations according to the test design. Put 200ml of mixed medicinal solution with different proportions in 250ml white ...

Embodiment 2

[0035] Example 2 The efficacy test of thiamethoxam and pyriproxyfen in the control of Anopheles sinensis and Culex pachypis larvae

[0036] Test method: with embodiment 1.

[0037] Statistical Analysis: Based on the findings, treatment-adjusted mortality rates were calculated. According to the formula (1) (2), the calculation result has two decimal places.

[0038] P = K N × 100 · · · ( 1 )

[0039] Among them, P—mortality rate, the unit is percentage (%);

[0040] K—the number of dead insects, the unit is head;

[0041] N—the total number of worms treated, the unit is head.

[0042] P 1 = P t - P o 1 - ...

Embodiment example 3

[0051] Implementation Case 3 Indoor efficacy test of sanitation pest insecticidal composition containing thiamethoxam and pyriproxyfen

[0052] The indoor drug efficacy test in this example was entrusted to the Guangdong Provincial Institute of Entomology and the Guangxi Institute of Health and Occupational Disease Prevention and Control respectively, and the results of the two were consistent. The following only uses the drug efficacy test of the Guangdong Provincial Institute of Entomology as an illustration.

[0053] Test agent: the pyriproxyfen·thiamethoxam soluble liquid agent with a concentration of 9% by weight of effective active components used in this example was tested, and its specific composition is shown in Table 4.

Abstract

The invention discloses a sanitary pest insecticidal composition containing thiamethoxam and pyriproxyfen; thiamethoxam and pyriproxyfen serve as active ingredients, wherein the weight ratio of thiamethoxam to pyriproxyfen is (1-5): 5. The invention further discloses an application of thiamethoxam and pyriproxyfen in preparing the sanitary pest insecticidal composition. The invention firstly discovers a function of thiamethoxam in killing mosquitoes and flies as well as larvae thereof as a sanitary medicine, and firstly discloses a composite compound of thiamethoxam and pyriproxyfen in the field of public health medicine; the composition, compared to a pyriproxyfen single dosage, has an obvious synergistic effect, and is convenient to use, low in administration amount, good in control efficiency, long in administration period and low in control cost; and the composition has a good application prospect in preventing and controlling larvae of mosquitoes and flies in a public water area.

Description

technical field [0001] The invention relates to the field of pharmaceutical compositions, in particular to a sanitation pest insecticidal composition containing thiamethoxam and pyriproxyfen and its application. Background technique [0002] Pyriproxyfen, also known as Mieyoubao and Pyroxyfen, is an insect growth regulator that disrupts the growth of insects with phenyl ethers. It is a new type of insecticide that is a juvenile hormone analogue. It has gastric toxicity, contact killing and systemic activity on pests. , used for foliar spraying and soil irrigation and root treatment. It is quickly systemically sucked after application and transmitted to all parts of the plant. It has good control effect on piercing-sucking pests such as aphids, planthoppers, leafhoppers, whiteflies, etc. . Pyriproxyfen has the effect of inhibiting the pupation and eclosion of mosquito and fly larvae. Mosquito and fly larvae will basically die at the pupal stage after exposure to the agent a...
