Embodiment 1

[0014] Dissolve 2.01 mg of cabergoline, 10 g of cooking oil and 10 g of sugar in 100 mL of warm water, mix with 980 g of rice, and dry in the shade at room temperature to obtain bait.

[0015] Put a large amount of bait at a fixed point and saturate it: During the breeding period of rodents, select two closed fences with the same mouse density, put 5 places of bait in one of the fences, and put 200g of bait in each place, and keep the bait saturated all the time. Bait was used as a control. The changes in the number of rats were recorded month by month, and the results showed that after 3 months, the number of rats in the experimental enclosure decreased by 81% compared with the control group, and no larvae were produced in the experimental group, indicating that the embryonic development was inhibited and thus absorbed by the mother.

Embodiment 2

[0017] Dissolve 5 mg of cabergoline, 10 g of edible oil and 1.01 g of milk powder in 100 mL of warm water, mix with 989 g of corn, and dry in the shade at room temperature to obtain bait.

[0018] Put the bait in batches at fixed points: During the breeding period of rodents, select two closed fences with the same mouse density, put bait in 3 places in one of the fences, each time 100g, replenish the medicine once a week, and do not throw in the other fence The bait was used as a control, and the changes in the number of rats were recorded monthly. The results showed that after 3 months, the number of rats in the experimental pen decreased by 81% compared with the control pen, and no females produced young, indicating that the embryos were absorbed and the pregnancy was terminated.

Embodiment 3

[0020] Take 10mg of cabergoline, 10g of edible oil, 1g of saccharin, and 4g of creamer, dissolve them in 100mL of warm water, mix them with 985g of peanuts, and dry them in the shade at room temperature to obtain bait.

[0021] Put the bait in a large amount at one time at a fixed point: during the breeding period of rodents, select two closed fences with the same mouse density, put bait in 4 places in one of the fences, 500g in each place, and put bait in the other fence as a control, 3 After one month, the number of rats was investigated. The results showed that: compared with the control fence, the number of rats decreased by 80%, the litter rate decreased by 64%, and the stillbirth rate increased by 70%. Survival, indicating that the treatment caused both embryo resorption and abortion, while the resulting live larvae did not survive, also indicates that the treatment inhibited milk secretion.

Abstract

The invention relates to a female chemically sterilizing rat bait, which is characterized by comprising 0.0002 to 0.002 percent of cabergoline, 0 to 1 percent of edible oil, 0.1 to 5 percent of ediblesugar and/or milk powder and the balance of one of unhulled rice, rice, wheat, corn, yellow bean the pea nut based on total 100 mass percent. The rat bait is high in palatability, long in control effect, safe and low in pollution, can reduce the population quantity of pest rats by over 80 percent within 3 months, ensures that most embryos are dead and that the larva survival rate is extremely lowor even zero and is simple in production process, low in cost, suitable to be promoted in large scale for controlling the population quantity of the pest rats and capable of controlling the hazard ofthe pest rats to be below an economic threshold for a long time.

Description

field of invention [0001] The invention relates to a rodent control bait, in particular to a female chemical sterile rodent control bait. Background technique [0002] Rodents are major global pests. In Asia alone, the food stolen by rodents is equivalent to the annual rations of 200 million people. In Asia and Africa, the food stolen by rodents accounts for 15% of the total production. %, while in South America this ratio is 5% to 90%. In addition, many wild rodents are also the germ bank of plague, and there are still many epidemic foci in the world today, such as Kazakhstan in central Asia, Tanzania in Africa, the United States and South America in the Americas, etc. In addition, new epidemics continue to emerge. source was discovered. Rodents not only endanger agriculture, forestry and animal husbandry, but also cause great damage to industries such as food, transportation, communication and construction, and can also spread dozens of dangerous zoonotic diseases.
