Embodiment 1

[0018] In the red imported fire ants invasion area, by applying the high-efficiency insecticide powder containing 0.1% beta-cypermethrin of the present invention (activated clay 40~50%, surplus is talcum powder), each active ant nest uses 10 grams, 15 grams, 20 grams, After 7d, 14d, 21d, 28d, and 35d, the results of observing and detecting the number of active ant nests and the number of worker ants are shown in Table 1 and Table 2:

[0019] Table 1 Number of active ant nests and number of worker ants in each treatment area before and after pesticide application

[0020]

[0021] Note: Those with the same letter after the number in the same column in the table indicate that the difference is not significant at the 5% level by analysis of variance (DMRT):

[0024] Note: The letters A and ab in the table indicate the significance of the difference at the 0.01 and 0.05 levels by Duncan's new multiple range met...

Embodiment 2

[0027] Apply respectively the insecticidal powder (activated clay 20~80%, surplus is talcum powder) that the present invention contains 0.05% beta-cypermethrin and 1% beta-cypermethrin, each active ant nest uses 10 grams, 15 grams, 20 grams, through 7d , 14d, 21d, 28d, and 35d to observe and monitor the number of active ant nests and the number of worker ants. The results are shown in Table 3:

[0028] Table 3 Number of RIFA active nests and worker ants in 0.05% beta-cypermethrin and 1% beta-cypermethrin treatment areas

[0029]

[0030]

[0031] Note: The same letter in the same column in the table indicates that the difference is not significant at the 5% level by analysis of variance (DMRT)

[0032] The results of examples show that the highest control effect of 0.05% beta-cypermethrin insecticide powder is 95% for active ant nests and 84.86% for worker ants. Applying 1% beta-cypermethrin insecticide powder, the best control effect on active ant nests was 96.65%, and...

Abstract

The invention relates to the technical field of red fire ants control, in particular to a high-efficiency insecticide powder for killing red fire ants, the active ingredient of which is beta-cypermethrin, and the mass percentage of beta-cypermethrin is 0.05% to 1%. Beta-cypermethrin is a contact insecticide with high insecticidal activity and fast knockdown speed. The content of the present invention is 0.05%~1%, which can effectively alleviate the contact activity and knockdown speed of this variety, so that it can bring the drug to the ant nest, Three days later, the poisoning intensified and the RIFA gradually died; activated clay and talcum powder have a high melting point and are easy to crush, and the crushed mesh can reach more than 1,000 mesh, thereby promoting the penetration of the drug into the villi of the RIFA body and carrying the drug to the already superficial interior , killing the whole nest of ants; the present invention uses talcum powder, activated clay and beta-cypermethrin to mix, which can effectively prevent the ground from being affected by the dissolution of the medicine when it is wet, and avoid water pollution at the same time.

Description

technical field [0001] The invention relates to the technical field of red fire ants prevention and control, in particular to a high-efficiency insecticide powder for killing red fire ants. Background technique [0002] The red imported fire ants were originally distributed in the Parana River Basin in South America (including: Brazil, Paraguay and Argentina). More than 100 million hectares of land in 12 states in the southern United States have been occupied by invasive fire ants. For those in the southern United States The economic loss caused by the affected area is estimated to be more than billions of dollars every year. It was first discovered in Guangdong, my country in 2007. In 2013, according to the list of administrative regions for the distribution of agricultural plant quarantine pests in China, RIFA is distributed in 7 provinces / regions and 169 counties (cities, districts) in China. [0003] Red fire ants have obvious aggressiveness and the ability to sting repe...
