Embodiment 1

[0019] Every 1000g of rodent sterilizer bait that inhibits sexual reproduction is prepared as follows: weigh 944.999g of rice and put it in a container, then weigh 1mg of nilestriol, dissolve it in 10ml of chloroform, and then add 5g of edible rapeseed After the oil is mixed with 50g of white sugar, dissolve it in 100ml of warm water, add the chloroform dissolved in nylestriol into the above warm water, stir evenly, then mix the warm water with the rice, put it in a closed container, soak for 12h, Stir 3 times during this period, and then dry in the shade at room temperature. During this process, chloroform is completely volatilized, and the rodent sterility bait for inhibiting sexual reproduction of this embodiment is obtained.

[0020] Put the above-mentioned bait in large quantities at fixed points 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 ea...

Embodiment 2

[0022] Every 1000g of rodent sterilizer bait that inhibits sexual reproduction is prepared as follows: weigh 988.995g of corn and put it in a container, then weigh 5mg of nilestriol, dissolve it in 15ml of acetone, and then add 10g of edible corn oil After mixing with 1g of milk powder, dissolve it in 100ml of warm water, add the acetone dissolved in nylestriol into the above warm water, stir evenly, then mix the warm water with corn, put it in a closed container, and soak for 24 hours, during which Stir for 4 times, then dry in the shade at room temperature, during this process, the acetone is completely volatilized, and the rodent sterility bait for inhibiting sexual reproduction of this embodiment is obtained.

[0023] Put the above-mentioned bait in batches at fixed points: during the breeding period of rodents, select two closed fences with the same density of mice, put bait in 3 places in one of the fences, each place 100g each time, replenish the medicine once a week, an...

Embodiment 3

[0025] Every 1000g of rodent sterilizer bait that inhibits sexual reproduction is prepared as follows: weigh 985.99g of wheat and put it in a container, then weigh 10mg of nilestriol, dissolve it in 20ml of acetone, and then mix 10g of edible peanut oil with Mix 1g of saccharin and 3g of creamer, dissolve in 100ml of warm water, add the acetone dissolved in nylestriol into the above warm water, stir evenly, then mix the warm water with wheat, put it in a closed container, soak 18h, stirred 4 times during, and then dried in the shade at room temperature, during this process, acetone was completely volatilized, and the rodent sterility bait for inhibiting sexual reproduction of this embodiment was obtained.

[0026] A large amount of the above-mentioned bait is carried out at one time at a fixed point: during the breeding period of rodents, two closed fences with the same mouse density are selected, 4 places of bait are put in one of the fences, each place is 500g, and the other ...

Abstract

The invention discloses murine chemosterilant bait for inhibiting digenetic propagation, which comprises the following components in the terms of 100 percent by mass in total: 0.0001-0.001 percent of nilestriol, 0.5-1 percent of edible oil, 0.1-5 percent of sugar and / or milk powder or saccharin and / or creamer and the balance of foodstuff. A proper amount of nilestriol is mixed into the proper bait, the obtained bait has good palatability to bandicoots and a durable control effect, is safe and low-pollution, and can ensure that the population quantity of the bandicoots is reduced by above 80 percent within 3 months and the pregnancy rate and the young production rate are extremely low even no young is produced; and the bait has the advantages of simple production process and lower cost, issuitable for massive popularization, and is used for controlling the population quantity of the bandicoots so that the damage of the bandicoots is controlled below the economic threshold for a long time.

Description

Technical field: [0001] The invention relates to a rodent control bait, in particular to a rodent sterilizer bait for inhibiting sexual reproduction. 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 found. 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 disease...
