Embodiment 1

[0015] Weigh 985g of rice and put it in a container, weigh 0.05g of mifepristone, 10g of cooking oil, and 4.95g of sugar, dissolve it in 100mL of warm water, mix it with the rice, and dry it in the shade at room temperature to obtain bait.

[0016] Put bait in large quantities at fixed points for a long time: select two closed fences with the same density of mice, put 5 places of bait in one of the fences, each time 200g, supplement every week, and the other fence is a control without feeding, the first After 1 month, the number of rats was investigated, and the results showed that the number of rats in the experimental pen decreased by 56% compared with that in the control pen. After the third month, the pregnancy situation of the rats was investigated again, and no pregnant females appeared in the experimental pen. After one month, the number of pests was investigated, and the results showed that the number of rats in the experimental enclosure decreased by 94% compared with ...

Embodiment 2

[0018] Weigh 988.85g of wheat and put it in a container, weigh 0.15g of mifepristone, 10g of cooking oil, and 1g of milk powder, mix and dissolve in 100mL of warm water, then mix with wheat, and dry in the shade at room temperature to obtain bait.

[0019] Put the bait in batches at fixed points: select two closed fences with the same mouse density, put 5 places of bait in one of the fences, each time 100g, add once every 3 weeks, and the other fence is a control without feeding After the first month, the number of rats was investigated, and the results showed that the number of rats in the experimental pen decreased by 60% compared with that in the control pen. After the third month, the pregnancy of the rats was investigated again, and no pregnant females appeared in the experimental pen. After the sixth month, the number of pests was investigated, and the results showed that the number of rats in the experimental enclosure decreased by 82% compared with the control enclosure...

Embodiment 3

[0021] Weigh 948.5g of corn and put it in a container, weigh 0.5g of mifepristone, 1g of cooking oil, 10g of milk powder, and 40g of sugar, dissolve them in 100mL of warm water, mix them with corn, and dry in the shade at room temperature to obtain bait.

[0022] Scatter the bait at multiple points: select two closed fences with the same density of mice, put bait in 8 places in one of the fences, each time 40g, add once a month, and the other fence is a control without baiting. Investigate the changes in the number of rats after 1 month, and the results show that the number of rats in the experimental enclosure has decreased by 64% compared with the control enclosure. After the sixth month, investigate the changes in the number of harmful mice, and the results show that the number of rats in the experimental enclosure has decreased by 88% compared with the control enclosure. %.

Abstract

The invention relates to a bait for controlling the sterilization of female pest rats, which is characterized by comprising the following components on the basis of total 100 mass percent: 0.005 to 0.05 percent of mifeprex, 0.1 to 1 percent of edible oil, 0.1 to 5 percent of edible sugar and / or milk powder and the balance of one of unhulled rice, rice, wheat, corn, yellow bean the pea nut. The bait for controlling sterilization of the female pest rats has the advantages of long-lasting control effect, no medicament resistance, high palatability, no environmental pollution, no safety hazard andthe like, is low in cost, simple in process, suitable to be promoted to control pest rat disaster in a large range and capable of reducing the population quantity of pest rats by over 80 percent within 6 months, reduces the pregnancy rate of female rates and even completely eradicates pregnant females.

Description

field of invention [0001] The invention relates to a rodent extermination bait, in particular to a novel rodent extermination bait for controlling the sterility of female pest rats. Background technique [0002] my country is a developing country with very serious rodent infestation. Rodent infestation not only endangers the production and management of various industries, but also dozens of zoonotic diseases spread by rodent infestation threaten human health from time to time. The main reason why rodent infestation is difficult to control is that the rodents have a strong fecundity. After a short-term mass extermination, the food and space resources in the extermination area can still provide protection for the reproduction of the remaining rats and the border-immigrated individuals, resulting in The pest population recovered in a relatively short period of time, and eventually even surpassed the original level. [0003] Early rodent control mainly relied on various physic...
