Description

Technical Field

[0001] The invention belongs to the technical field of rodent pest control, and particularly relates to a rodent attractant based on rodent pheromone and a preparation method thereof. Background Art

[0002] The main types of rats in my country's cities include: Rattus norvegicus, Rattus houseus and Rattus flavipectus. At the same time, in the urban living areas where we live, we often see traces of rats escaping. Rats have a fast reproduction rate. For example, house mice can have up to 8 pregnancies a year, with 4-7 babies in each litter. The main hazards of rats are: 1) carrying bacteria and moving around indoors with rats, spreading diseases; 2) destroying items such as clothing, furniture, cardboard, packaging materials, wires, etc., bringing harm and anxiety to people's lives.

[0003] In developed countries, there are stricter legislations for the management and research of wild animals, including rodents, and there are very strict regulations for the use of wild animals such as rodents in research. In the formulation of pest control strategies, including rodent damage, the protection of the ecological environment is often placed in the first place. Compared with developed countries in Europe and the United States, due to the pressure of grain production in my country, the tolerance threshold for rodent damage is lower, which is also the fundamental reason why my country's rodent damage practice activities are the most active. The main problems we are currently facing are the lack of eco-friendly rodent control technology.

[0004] The ideas and methods of rodent control have evolved from the single killing of harmful rodents to the eco-friendly rodent control concepts and technologies. Rodenticides are strictly controlled pesticides in my country, mainly because of the safety risks they pose to humans and the environment. Taking cities as an example, when the climate warms, rats roam indoors and outdoors, and the rat density increases; the frequent movement of people in cities and the large amount of domestic garbage make suitable habitats for rodents continue to appear, thus keeping the number of rodents basically stable throughout the year. Especially in places such as garbage recycling stations and warehouses, where there is an adequate source of food, traditional methods of catching rats with food bait, including rat traps, rat poison, sticky rat boards, etc., often show limitations such as insufficient capture efficiency, high failure rate, and inability to capture continuously, making it difficult to reduce the harm of rodents. The current formulas of rodent attractants are all based on food and its volatile odor, which cannot solve the limitation of insufficient ability to attract rats in some areas, such as urban centers, where food sources are relatively abundant. Summary of the invention

[0005] To solve the above problems, the present invention proposes an efficient and long-lasting rodent attractant based on animal pheromone, a chemical substance secreted from glands in animals to the outside of the body to induce behavioral or physiological reactions in other individuals of the same species. The rodent attractant has the characteristics of stable ingredients, long-lasting and stable effects, and convenient storage.

[0006] Specifically, the rodent attractant provided by the present invention is prepared from the following raw materials in percentage by mass: 5-8% hexanoic acid, 6-17% 6-methyl-5-heptene-2-one, 5-8% 4-methylphenol, 3-16% squalene, 20-30% (E)-β-farnesene, 25-35% (E,E)-α-farnesene, and 2-20% mineral oil.

[0007] Preferably, the rodent attractant is prepared from the following raw materials in percentage by mass: 5% hexanoic acid, 6% 6-methyl-5-heptene-2-one, 8% 4-methylphenol, 16% squalene, 20% (E)-β-farnesene, 25% (E,E)-α-farnesene, and 20% mineral oil.

[0008] Preferably, the rodent attractant is prepared from the following raw materials in percentage by mass: 8% hexanoic acid, 17% 6-methyl-5-heptene-2-one, 5% 4-methylphenol, 3% squalene, 30% (E)-β-farnesene, 35% (E,E)-α-farnesene, and 2% mineral oil.

[0009] On the other hand, the present invention also provides a method for preparing a rodent attractant, which comprises the following steps: respectively weighing the raw materials of each component in the formula, stirring and mixing the raw materials, sealing and letting them stand to obtain the rodent attractant.

[0010] Preferably, the stirring speed is 300-500 r / min, the stirring time is 20-40 min, and the stirring temperature is 10-40°C.

[0011] Preferably, the standing time is 60-240 min.

[0012] On the other hand, the present invention also provides the use of the rodent attractant in rodent control.

[0013] In addition, the present invention also provides a method for controlling rodent pests, which comprises the step of placing the above-mentioned rodent attractant in a place where rodent pest control is required.

[0014] The present invention has the following beneficial effects:

[0015] The rat attractant of the present invention is developed based on animal pheromones, and has the advantages of strong inducing power, high efficiency, safety, and durability. On the one hand, it helps to improve the current situation of low capture rate caused by abundant food sources, and on the other hand, it solves the shortcomings of pure food-based baits, and has great social value.
