Embodiment 1

[0018] Example 1: Determination of combined toxicity of metarhizine and pyriproxyfen to Aedes albopictus

[0019] Test reagents: metarhizine original powder (South China Agricultural University), pyriproxyfen original drug (Shanghai Shengnong Biochemical Products Co., Ltd.).

[0020] Test object: 2-3 instar larvae of Aedes albopictus (Aedes albopictus Skuse)

[0021] Test method: According to the WHO larva immersion method. The test uniformly uses a 500ml beaker as the test container, selects the appropriate concentration gradient range through the preliminary experiment, and sets 5 concentration gradients within the appropriate concentration range. 50 three-day-old larvae were put into each cup, and all treatments were placed in an incubator at 25°C with a photoperiod of 12:12; relative humidity was 60±5%. After 5 days, observe and record the number of dead larvae, repeat 3 times, and calculate the corrected mortality rate of each treatment according to the survey data. An...

Embodiment 2

[0045] Example 2: The formula and processing method of metarhizine·pyriproxyfen granules.

[0046]

[0047] Pulverize the above formula according to the proportion, put it into the mixer and stir evenly, then add water to the granulation tray to granulate, dry the prepared granules in an oven, cool, sieve, and pack to obtain 6% metarhizine · Pyriproxyfen granules.

Embodiment 3

[0048] Embodiment 3: The formulation and processing method of metarhizine·pyriproxyfen aqueous emulsion.

[0049]

[0050] Add the metarhizalin, the pyriproxyfen, methanol, and xylene solvent into the mixing tank in sequence, stir evenly, and add alkyl polyglycol ether, lignosulfonate, isobutyl Alcohol, xanthan gum, tert-butyl-p-hydroxyanisole, ethylene glycol, deionized water, high-shear for 1 hour to obtain a water-emulsion insecticidal composition, and fill.

Abstract

The invention relates to an insecticidal composition with a synergistic action. The insecticidal composition is prepared by taking destruxin and pyriproxyfen as basic active components and mixing the destruxin and the pyriproxyfen according to the following ratio of 1g to (1-99)g. After the two effective components are mixed, the insecticidal composition can be applied to preventing and controlling health pests including aedes albopictus, flies and termites and preferably preventing and controlling diptera health pests including mosquitos, flies and the like.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to an insecticidal composition containing metarhizine and pyriproxyfen, a preparation method and application thereof. Background technique [0002] Metarhizin (destruxin), also known as putrefaction or destroyin, is a cyclic destruxin toxin composed of 5 amino acids and 1 hydroxy acid, and is a secondary metabolite produced by Metarhizium anisopliae during metabolism , has contact killing, stomach poisoning and antifeedant effects on more than 20 kinds of pests such as Lepidoptera, Homoptera, Diptera, Isoptera, Orthoptera and Coleoptera; Or the mixed use of commercial insecticides has a synergistic effect, such as mixing with Beauveria bassiana, Paecilomyces javanica, Metarhizium anisopliae, etc. can significantly improve the control effect on Bemisia tabaci, Spodoptera litura, grubs, etc.; with Bt, The mixed use of abamectin and imidacloprid can also significantly i...
