JPS59106408A - Attraction and extermination of rat - Google Patents

Abstract

PURPOSE:To exterminate any rats which like a plant bait or an animal bait, by using an attractant containing a fragrant component of odorized rice or its extracted essence, a synthetic perfume to imitate the fragrance, or its blend as an active ingredient. CONSTITUTION:Rats are exterminated by using an attractant containing a fragrant component of rice with high fragrance such as odorized rice, perfumed rice or musk rice, or its extracted essence, a synthetic perfume to imitate the fragrance, or its mixture as an active ingredient. The attractant has high attracting action on any kinds of rats and raising action on palatability ratio of bait blended with the attractant, and is effective against both rate which like a plant bait, such as house mouse, Japanese field vole, old world woods rats, etc. and rats which like an animal bait, such as brown rat, black rat, etc.

Description

[Detailed Description of the Invention] The present invention relates to a method for attracting and exterminating rats using an attractant for rats whose active ingredient is the aromatic component of fragrant rice or a synthetic fragrance prepared to resemble this aroma. .

The present invention is a type of rice with a strong aroma called kaoshi rice, odor rice, or jakora rice that is cultivated by a very limited number of farmers. discovered that it has a strong attracting effect on all kinds of rats that are common in Japan, such as brown rats, and that it has the effect of increasing the eating rate of bait containing it. We have developed an effective method for attracting and exterminating rats.

In other words, the conventional thinking is that because of their different eating habits, the degree of attraction by food is different between brown rats, voles, red rats, etc., which prefer plant-based food, and brown rats, black rats, etc., which prefer animal food. Although this is common, it is truly surprising that when the flavoring agent of the present invention is used, it exhibits a strong attracting effect on rats with any eating habits.

Next, an attracting fragrance was prepared as follows.

[Example 1] Acetamide dry distilled product 10 parts Butyric acid amide dry distilled product 8 parts Cyclohexyl butyrate i,9s indole 01 parts Alcohol 80 parts The above ingredients were mixed and dissolved to form a uniform liquid. 0.02 to 0.05% of this material is mixed into rat food.

[Example 2] Dried yeast], 00'/ was immersed in 1 t of enzyme papain aqueous solution and hydrolyzed. Glucose] 507 was added to the acidic acid solution and evaporated to dryness by heating. After heating on a heating table at 140° to 1600° for 30 minutes. , add 1 ton of the mixed solution of Example 1, and mix the mixture until the whole is homogeneous. 0.02 to 0.05% of the solution is mixed into rat food.

The following test was conducted using the above perfume.

■ Seal the following feed for the test animal in flea rough-in, and place it in a thin polyethylene cup (approximately 1ocrn x 1oCTn x 2 + f
f+) and used as a test animal. Paraffin is used for the purpose of preventing the spoilage of bait and the hydrolysis of zinc phosphide as a poisonous agent, and sustaining the rat-killing effect under snow cover.

■Grain (ground corn, canary seeds, wheat) ・・・・・・・・・Approx. 48% ■Grain (flour)
・・・・・・Approx. 4% ■Sugar −・・・・
...Approx. 3% ■Fragrance (prepared according to Example 1 to match the aroma of Shijako rice) ...0.02% and 0.035% ■Paraffin ... Approx. 45% ■ Test animals In each test, one male and one female Tanesumi were placed in a mouse breeding box (stainless steel, 35 cm x 25 cm x 15 cm) was used. The test animals for each test are separate individuals.

■ Placement of test feed As for the test feed, the above-mentioned domestic voles were placed in polyethylene cups and fed with -1-year-old food in a rearing box in a random order.

■ Ingestion amount The test feed was 1607 in a polyethylene cup, and the food was fed to 2 voles for 7 days, and then re-measured to calculate the ingestion amount.

Table 1 shows the results of raising voles under normal conditions and feeding them a test feed containing a fragrance adjusted to match the scent of musk rice and a control test feed containing no fragrance. The main content was as follows.

In other words, when voles were fed normal food and test feed in a breeding box, they preferred to eat the normal food such as dry-pressed corn for raising dairy cows, fresh white clover, and the food with flavoring added. The test animals to which no supplement was added did not eat at full heat. Therefore, if a new test feed is introduced in addition to the food that they are accustomed to eating, they tend to avoid it, but if this new test feed is added with a flavoring that has the aroma of musk rice. It was found that they have a habit of preferring to eat.

In other words, the control feed to which no flavor was added was not eaten in all three feeding tests. In the first feeding test, the intake amount was 0%, but in the second test, the intake amount was 6%.
．． 1? (3,8%), 3rd time C), 9?
(0.6%), which was a very small amount. Therefore, even if the test feed contains a very small amount of fragrance, about 0.2%, it is thought that the No. tanesumi will sense this and eat it. Next, it appears that voles were significantly discouraged from eating the test feed containing 0.35% flavoring, and in the first feeding test, the food intake was 38.69% (24,
1%) were ingested, and in the second time, 47.89 (
29.9%), and in the third time, 68.9 f
(43,1%) were consumed, respectively.

In view of the above results, if voles are fed the usual food for raising dairy cows, such as dry-pressed corn, raw clover, and water, in addition to this food, they can also receive test feed newly encapsulated in paraffin. Even if you give it to them, they tend not to eat it. However, this test feed contained 0.35% fragrance.
If added, there is a tendency to eat it significantly. Based on this, it is thought that adding a flavoring agent ($5) to the bait for placement will significantly increase the intake of voles.

Table 1: Amount of flavored bait consumed by voles In carrying out the present invention, when using it as an attracting bait for a trapping device, it may be mixed with flour etc. and kneaded with water to form a ball, or It can be used by absorbing it into a sponge-like material. When used on adhesive paper, mix it with adhesive or
It can also be placed in the center of the sticky board as an attractant bait.

When mixed with poison bait, any of the conventional rodenticidal active ingredients such as zinc phosphide, oxycoumarin, silyloside, crocotuacinone, guifacinone, etc. can be used, and other auxiliary ingredients such as wheat flour, rice flour, Corn flour, buckwheat flour, cinchona flour, pupa flour, fish meal, etc., and seasonings such as sugar, monosodium glutamate, saccharin, and chili powder, as well as animal and vegetable oils, wax, and red, black, and purple pigments can be used. , anti-type is granular, granular, powder,
It may be measured in lumps, etc., but depending on the concentration of the active ingredient,
It is sufficient if it is formulated in such a way that a single serving can reach a lethal dose for rats. For example, if 1% zinc phosphide is added and used in a region where there are a lot of 257-year-old Japanese porcupines, one grain will weigh 0.17.
It is used as a granular poisonous bait, and one poisonous bait kills one Ezo voles, but if you want to prevent fruit trees from being damaged by voles in orchards etc. under the snow for several months, knead them with ξ rough-in. One piece of 202 blocks of poison bait is used, which is equivalent to feeding more than 100 voles.
