Description

technical field [0001] The invention relates to the technical field of insecticidal herbicides, in particular to a contact killing agent for red imported fire ants. Background technique [0002] The red fire ant belongs to the Formicidae insects of the order Hymenoptera. Its body is brown, and its body is larger than ordinary ants. The adult body is 3 mm to 6 mm long. The red fire ant is one of the most destructive invasive organisms listed by the International Union for Conservation of Nature, and it has huge damage to humans, animals and plants. RIFA originated from South America and was introduced to the United States in the 1930s, and spread from the United States to Australia, Hong Kong, and Macau through containers and turf in the early 21st century. [0003] RIFA has strong adaptability, miscellaneous feeding habits, strong fecundity and aggressiveness, and it may break out into disasters in a short period of time in newly introduced areas. The harms caused by RIFA ...

Problems solved by technology

There are many medicines for controlling and preventing RIFA at home and abroad, and the dosage forms are basically granular medicines and powders. The components of these medicines for killing RIFA are basically composed of insecticides, attractants, baits, and preservatives. Among them Fish meal, spices, protein powder, etc. are mostly used as attractants, and corn flour, soybean meal, etc. are used as bait. These attractants and baits have poor ability to attract red imported fire ants and eat less food, resulting in poor ant killing effect and wasting a lot of food resources. And pollute the environment, the cost of prevention and control is high
