Embodiment 1

[0034] Embodiment 1: the control experiment comparison of different bait to RIFA

[0035] Control object: red fire ants (Solenopsis invita Buren)

[0036] Formula content: N-n-butyl perfluorooctane sulfonamide 0.5%, soybean powder 41%, sugar 43%, shrimp powder 10%, honey 4%, flavor 1%, sorbic acid 0.5%.

[0037] The field efficacy test on RIFA by the Plant Quarantine Station of Guangxi Zhuang Autonomous Region, the test method and results are as follows:

[0038] Test setup: Select the RIFA ant nest with worker ant activity as the test area, demarcate the boundaries and mark the four corners with obvious markers, and the edge of each cell is separated by more than 5-10 meters, and the signs are inserted, and each cell has activities. There are no less than 5 ant nests. Three replicates were set for each of the six chemical treatments, with a total of 101 ant nests in 18 plots, and biscuit crumbs were selected as a control. (The active ant nest refers to a thin wooden strip ...

Embodiment 2

[0047] Example 2: Monitoring of bait control effect of 0.05% N-n-butyl perfluorooctane sulfonamide

[0048] Tested by the Institute of Plant Protection, Chinese Academy of Agricultural Sciences, the test methods and results are as follows:

[0049] 1. Materials and methods

[0050] 1.1 Experimental area

[0051] The experimental area is located in the National Software Industry High-tech Zone in Zhuhai City, Guangdong Province (113°34′E, 22°26′N, 9m above sea level). The total area of ​​the park is 157,000 m2. The construction of grassland or green belt was completed in 2004, and the area (including a small amount of ponds) is about 62,000 m2. There are 749 ant nests in total. The main vegetation in the green belt is bermudagrass and some bushes. The distribution of ant nests is very diverse, and there are ant nests on the grass, among the bushes, on the steps, ponds and roadsides.

Embodiment 3

[0091] Example 3 Application rate experiment

[0092] After the field efficacy test of RIFA by the Institute of Plant Protection, Chinese Academy of Agricultural Sciences, the test methods and results are as follows:

[0093] 1 test site

[0094] The test site is located in Liangshuijing Village, Beiliu Town, Beiliu City, Yulin City, Guangxi (latitude 22°43.140 north, longitude 110°17.173 east). The test area covers an area of ​​about 20 mu, with roads in the east, lychee gardens in the west, and residential houses in the north and south. The vegetation on the ground is mainly bermudagrass. The largest ant nest is about 80cm in diameter and 40cm in height. The density of ant nests in the central area is about 14 / 100m2. The trial period was from September 12 to October 21, for a total of 40 days. During the test, the average temperature was 27.7±1.5°C, the highest was 34°C, and it rained for 10 days, but the rainiest day was only 8mm.

Abstract

The invention relates to a pesticide used for preventing and controlling red imported fire ants, belonging to the technical field of agricultural chemicals. The pesticide comprises baits which are N-butyl perfluor octane sulphonamide. The pesticide prepared by the invention is better than like products at home and abroad no matter in the aspects of allure and palatability for red imported fire ants or in the aspects of control efficiency; and the control efficiency can reach 95%-100% when the pesticide is used in a sufficient quantity.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a pesticide and insecticide for preventing and controlling RIFA. technical background [0002] The red fire ant (Solenopsis invictaBuren) is native to western Brazil, Argentina, Paraguay and the Panama Canal. It was introduced to Alabama in the United States from 1930 to 1940, and has now spread to 13 states and Puerto Rico in the United States. 128 million hectares. In my country, RIFA was found in Taiwan in 2003, and after 2005 in Guangdong, Guangxi, Hunan, Fujian and other provinces, as well as parts of Hong Kong and Macao. Because RIFA has strong reproductive potential and strong adaptability to the environment, and spreads rapidly, wherever it goes, it is rampant and has become the number one local pest. RIFA endanger human health and life, destroy agriculture, biodiversity and public facilities, and cause major economic losses. These hazards have been reflected to vary...
