Embodiment 1

[0030] Embodiment 1: the structure of injector

[0031] like figure 1 , figure 2 and image 3As shown, the injector of the present embodiment includes a high-pressure injection gun 10, a screw interface 1 and a retractable injection spray pipe connected to it below the interface, and the screw interface 1 is connected to the injection pipeline of the high-pressure injection gun 10 , the upper part of the injection spray pipe is provided with an umbrella cover 2, the umbrella cover can prevent the medicine from spraying out in the spray holes exposed outside the ant nest, and the injection spray pipe is composed of 3 joints socketed in pairs Injection and spraying sub-pipes are composed of the first, second and third injection and spraying sub-pipes 3, 4, and 5. Each section of injection and spraying sub-pipes is about 20-30cm long, and the injection and spraying sub-pipes of the previous section are set in the next section In the injection spraying branch, there is a block...

Embodiment 2

[0032] Example 2: Indoor toxicity test of the compound main agent of Beauveria bassiana and thiacloprid on red imported fire ants worker termites

[0033] During the indoor toxicity test, a total of 1.5 g of Beauveria bassiana powder and thiacloprid were weighed (the mass ratios of Beauveria bassiana powder and thiacloprid were respectively: 1:0, 8:2, 6:4, 5:5, 4:6, 1:9 and 0:1, the Beauveria bassiana powder used contains 20 billion spores / g of Beauveria bassiana, the content of the thiacloprid original drug is 95% by mass, the actual preparation calculation is the same as that of Beauveria bassiana When the mass ratio is calculated based on pure thiacloprid), the wetting agent pulls apart powder 0.4g, the dispersant sodium lignosulfonate 0.9g, the disintegrating agent calcium chloride 0.25g, the stabilizer disodium hydrogen phosphate 0.1g, the binder Sodium polyacrylate 0.25g, carrier diatomaceous earth 1.6g. The above raw materials are put into mixing according to the prepa...

Embodiment 3

[0040] Prepare 30% Beauveria bassiana · Thiacloprid (1.2% Beauveria bassiana+0.3% Thiacloprid) water dispersible granules, the quality of each component is respectively: take by weighing Beauveria bassiana powder 1.2g, thiacloprid 0.3g , wetting agent pull open powder 0.4g, dispersant sodium lignosulfonate 0.9g, disintegrant calcium chloride 0.25g, stabilizer disodium hydrogen phosphate 0.1g, binder sodium polyacrylate 0.25g, carrier diatomaceous earth 1.6 g. The above raw materials are mixed according to the preparation method of water-dispersible granules (referring to Example 2), and 30% Beauveria bassiana·thiacloprid water-dispersible granules (the medicament for preventing and treating red imported fire ants containing pathogenic microorganisms) are obtained. The used Beauveria bassiana powder contains 20 billion spores / gram of Beauveria bassiana, and the content of the original drug of thiacloprid is 95%. When calculating the mass ratio of Beauveria bassiana in actual pr...

Abstract

The invention discloses an injecting type biological prevention and control method in a solenopsis invicta nest. The injecting type biological prevention and control method is characterized by comprising the following steps: utilizing an injection device to insert a solenopsis invicta preventing and controlling agent containing pathogenic microorganisms into the solenopsis invicta nest, spraying the agent to each depth and position of the solenopsis invicta nest, and uniformly sprinkling the agent on solenopsis invicta bodies in each depth and position of the solenopsis invicta nest. Through utilizing the prevention and control method, the contact area of the pathogenic microorganisms and target insects can be increased, and solenopsis invicta nest moving phenomena caused by the damage of nest irrigation and chemical application on the ant nest are avoided; and besides, the humidity in the nest can be properly increased, and the environmental condition that the solenopsis invicta is infected with the pathogenic microorganisms is improved, so that the solenopsis invicta is more easily infected with various pathogenic microorganisms, and the insecticidal activity of the pathogenic microorganisms on the solenopsis invicta is enhanced. The injecting type biological prevention and control method has great prevention and control effects and finally achieves prevention and control purposes.

Description

[0001] Technical field: [0002] The invention belongs to the field of prevention and control of red imported fire ants, and in particular relates to an injection-type biological prevention and control method in the nest of red imported fire ants. [0003] Background technique: [0004] RIFA solenopsis invicta belongs to the order Hymenoptera, Formicidae, Myrmicinae, and the genus Solenopsis. It not only feeds on seeds, fruits, young shoots, tender stems and roots of agricultural and forestry plants, It also preys on soil-dwelling animals, bites poultry and livestock, and even attacks humans, endangering public health safety. Since the first discovery of RIFA in Wuchuan City, Guangdong Province in mainland China at the end of 2004, it has posed a serious threat to the production of agricultural ecosystems and the structure and function of natural ecosystems in our province. At present, the prevention and control of RIFA mainly include: distributing bait, dusting agent, nest ir...
