It was designed so that it could be caught.

The results of the repellent effect test using the above-mentioned rat repellent ultrasonic transmitter are as follows.

1. Test method A device such as that shown in FIG. 2 was prepared, a black rat (150 g, male) captured in a building in Tokyo was released into the test device, and a water supply bottle was provided at parts a and b in FIG. A feed (feed CL-2 for rats manufactured by CLEA Japan, Inc.) was placed and allowed to freely eat. Further, a passage recognition counter was set near the entrances of the portions a and b, and the number of times the mice passed was measured. In order to accustom the black rats to the test apparatus, they were bred for 2 weeks without ultrasonic waves. After 2 weeks, behavior and eating amount were observed when ultrasonic waves were transmitted to only part a or part b for 24 hours and ultrasonic waves were transmitted to part b only for 12 hours at night. The ultrasonic wave transmission device was installed at a height of 2 meters in each part of ab, and the periphery thereof was covered with a blocking material. The ultrasonic waves used were 19 kHz, and the sound pressure was 135 dB or more.

2, Test Results and Discussion a) No ultrasonic wave transmission for both a and b (Table 1): The total number of visits to a and b during the observation period of 14 days was 2422.
1229 times to part a and 11 to part b
It was 93 times. Maximum number of times per day is 2 in part a
21 times, a minimum of 56 times, and an average of 87.8 times. on the other hand,
In part b, the maximum was 207 times, the minimum was 22 times, and the average was 85.2 times. However, there was a large difference in the amount of food consumed in ab, and almost no food was eaten in b. The average daily eating amount was about 10 g.

(Table-1)

B) Continuous transmission for 24 hours At the time of partial transmission: During the test period of 8 days, the total number of times a and b were performed was 966, and the number of times a was transmitted to the portion a where ultrasonic waves were transmitted was A total of 108 times, up to 19 times a day
The average was 13.5 times with a minimum of 2 times. On the other hand, a total of 858 times for the part b where ultrasonic waves are not transmitted is 1
There was a clear difference between the maximum of 313 times a day and the minimum of 27 times, and an average of 107.3 times. As for the amount of food consumed, almost no food was eaten in the portion a where ultrasonic waves were transmitted.
In addition, the amount of food consumed was reduced to an average of around 6.75g,
It is presumed that a lot of stress is added (Table-
2).

(Table-2)

When transmitting part b: a, b during the test period of 8 days
1,356 times in total, of which only 64 times to the portion b where the ultrasonic waves are transmitted, the maximum was 17 times a day, and the minimum was 3 times. On the other hand, 1292 times were sent to part a which was not transmitted, and the maximum was 356 times a day, and the minimum was 41 times, which was an average of 161.5 times. Looking at the amount of food consumed, although the test start date was a minimum amount, the food was eaten in the transmitted part b, but from the next day, almost no food was eaten in the part b, and only the part a was the same as the previous test result. there were. Furthermore, the amount of eating was the same result (Table 3).

(Table-3)

C) 12 hours at night b Partial ultrasonic wave transmission (Table-
4) The test was carried out for 7 days, and a total of 229 times passed to the part a in the daytime, whereas 91 times to the part b. It was
This result was quite different from the result of no call. That is, in the non-transmission test, the numbers ab were almost the same. The cause of this is that the result of the non-transmission test is the number of times of passing in one day, and it is considered that it is not measured by day and night. In addition, in the test without a call, the place a was eaten a lot, but this time, no difference in the amount of food consumed was found.

(Table-4)

On the other hand, the result at night was 563 times in total in the non-transmitting part a, whereas it was 9 in the sending part b.
It only passed 9 times. In addition, the amount of eating was eating at the part a where there was no transmission. In addition, the daily consumption is 7.5g on average.
Met.

From the above results, it was confirmed that the rat-use ultrasonic transmitter has a repellent effect on the rat.

[0037]

According to the present invention, the following effects can be obtained based on the above configuration. (1) It can be provided at low cost because it does not need to employ an advanced control system. (2) It is of course not surprising to the mouse, but various synthetic waves can be transmitted at random, so an effect of preventing habituation (learning) can be obtained. (3) By using a plurality of transducers, on / off control can be easily performed by a signal from a timer or various sensors. (4) It is possible to ensure the mouse repellent action in the specific area.
