Compound type red imported fire ant aerosol

Abstract

The invention relates to the field of red imported fire ant prevention drugs. A compound type red imported fire ant aerosol provided by the invention comprises an active compound, an active compound solvent and a propellant, wherein the active compound is a mixture of fipronil and flursulamid, and the percentage of the weight of the mixture to the total weight of the aerosol is 0.01-1.5%. The compound type red imported fire ant aerosol is not influenced by air temperature and earth surface humidity so that the control on red imported fire ants can be also performed in winter not suitable for applying baits; compared with powder, the aerosol has the advantages that tiny fogdrops sprayed out by the aerosol easily attach the body surfaces of the red imported fire ants, and the attachment amount is large, so that the pesticide effect is good; in addition, the active compound is prepared by compounding fipronil and flursulamid, fipronil and flursulamid do not have cross resistance and have different acting mechanisms, fipronil has a high pesticide effect, and flursulamid has a slow pesticide effect, so that the pesticide effect exertion has certain time difference, thereby facilitating conducting of the pesticide in a whole ant nest and the red imported fire ants are completely killed.

Description

technical field [0001] The invention relates to the field of drugs for preventing and controlling red imported fire ants. Background technique [0002] Red fire ants (scientific name: Solenopsis invicta ), a type of fire ant. It is an agricultural and medical pest native to South America. It was introduced to the United States in the 1930s, and spread from the United States to Australia, Taiwan, and Wuchuan County, Guangdong Province, China through containers and turf in 2001 and 2002, and then spread to other cities in Guangdong Province, Hong Kong, and Macau. [0003] Several RIFA control drugs and their preparation methods are disclosed in the Chinese patent database, and the dosage forms of these drugs are mainly baits and powders. The bait is composed of gastric poisoning drugs and the food that RIFA prefers to eat. According to the habit of RIFA worker ants actively going out of the nest to forage, the drug is sprinkled next to the ant nest, and the worker ants carr...

AI Technical Summary

Problems solved by technology

For baits, RIFA can actively forage for food only under a certain temperature and humidity. If the temperature is too low or the surface humidity is too high, worker ants seldom go out to forage. Under such temperature and humidity, the dosage of RIFA to carry back to the nest If the bait is too small, or not transported back to the nest at all, the time of dosing is too long, and the bait is damp or moldy, the manpower and time of dosing wi
