m. The eaves 25 were formed upward from the horizontal plane so that α was 13 °.

As a comparative cockroach bait storage container (hereinafter referred to as a comparative container (1)), cockroaches enter the four sides of a cylindrical flat container shown in FIG. A container provided with an entrance and exit comprising a tunnel-like passage 70 capable of performing the above-mentioned operations was used. However, the comparative container (1) was prepared in the same configuration as the container (1) except for the following points. That is, in the container (1), as shown in FIGS. 1 (a) and (b) to FIG. 3, an opening 23 is provided in a lower portion of the side wall 22, and an upper edge of the opening 23 (the notch 23
a) While the eaves 25 are formed on the whole, in the comparative container (1), as shown in FIG. 18, the side wall 22 at the opening forming position is notched from the top wall 21 to the bottom wall 11. The opening thus obtained is provided with an entrance formed by a tunnel-like passage 70.
Of the tunnel-shaped passage 71 in the comparative container (1),
The length m protruding from the bottom wall 11 was 10 mm. No poison bait was used for both the container (1) and the comparative container (1).

First, Vaseline (trademark) was applied to a portion 5 cm from the top of the inner wall of a transparent resin bat 30 cm in diameter and 10 cm in height to prevent cockroaches from escaping.
As cockroaches, 50 males and 50 females of the German cockroach were put into this bat and left as it was for 3 hours to adapt to the environment.

Next, the container (1) and the comparative container (1) were simultaneously placed almost at the center of the bat, and cockroaches were observed for 5 minutes. After 5 minutes, the container (1) and the comparative container (1) are collected, and after 5 minutes,
Again, the container (1) and the comparative container (1) were simultaneously placed on the vat, and the number of cockroaches in and out was observed in the same manner as the first time. This operation was repeated five times. Table 1 shows the results.

[0106]

[Table 1]

From the results shown in Table 1, the number of cockroaches invading the container (1) according to the present invention is much higher than that of the comparative container (1), and the number of inhabited cockroaches (that is, The number of cockroaches that did not escape into the container (1) was found to cover the container (1) as compared with the comparative container (1). This indicates that when the bottom wall is provided below the eaves, the attraction performance and the latent performance tend to be reduced.

Example 2 In Example 1, instead of the comparative container (1), a triangular tunnel-shaped cockroach bait storage container (hereinafter referred to as FIG. 19) having a space through which poison bait can be stored and cockroaches can pass. , Comparison container (2))
The same operation as in Example 1 was performed except for using, and the number of cockroaches in and out was observed. Table 2 shows the results.

The bottom wall 71 of the comparative container (2) is rectangular, and the length p of the bottom wall 71 in the longitudinal direction, that is, the length of the bottom wall 71 on the side where the side wall 72 is formed is 78 mm, and the length q in the short direction is q. Is 6

The length s was 30 mm. In addition, the comparative container (2)
Again, no bait was used.

[0110]

[Table 2]

From Table 2, it can be seen that although the number of cockroaches invaded by the comparative container (2) was larger, the number of escapes was larger, and the number of cockroaches occupying in the comparative container (2) according to the present invention was higher. (1) It can be seen that the number of cockroaches inhabiting inside is overwhelmingly large. That is, even if the cockroach once invades the comparative container (2), it cannot be said that it merely passes and does not take in enough food to obtain a sufficient control effect. On the other hand, the container (1) according to the present invention shows that although the number of cockroaches invaded by the comparative container (2) was larger than that of the comparative container (1) according to the result of Table 1, it was found from Table 2. The attraction performance of the container (1) is quite high.

Therefore, it can be seen from the above results that the container (1) according to the present invention is excellent in both the cockroach attracting performance and the latent performance, and can exterminate cockroaches efficiently.

Example 3 A bait (non-toxic) was weighed in cockroach bait storage containers (hereinafter referred to as container (2), container (3), comparative container (3)) having different eave lengths. (Bait) was housed (attached), and this was previously released into a cockroach to adjust to the environment.
m). As the cockroaches, seven male and eight female black cockroaches were used.

As the container (2) and the container (3), a container having the structure shown in FIGS. 6A and 6B, that is, a container in which the eaves 25 are provided in a part of the cutout portion 23a was used. .
In addition, in both the container (2) and the container (3), as in the case of the container (1), the eaves 25 were formed upward from the horizontal plane so that α was 13 °. The container (2) and the container (3) were prepared in the same configuration as the container (1) used in Example 1 except for the following points. The container (2) has a height g up to the lower end 25c of the eave 25 at the interface with the opening 23.
(See FIGS. 2 and 6), the opening height b (the maximum height of the opening 32; see FIG. 2) was 10 mm, and the length k of the eave 25 (the width of the protrusion from the opening 23) was 15 mm. . In the container (3), the length k of the eave 25 is set to 10 in the container (2).
mm. As the comparative container (3), a container in which the eaves 25 were not provided in the container (2) was used.

Then, the container (2),
Every five minutes after placing the container (3) and the comparison container (3) side by side, the cockroaches lurking in each container (vessel (2), container (3), comparison container (3)) five times I checked the number. Also,
Twenty-four hours after the container (2), the container (3), and the comparative container (3) were first juxtaposed to the vat, the weight of the bait (non-toxic bait) remaining in each container was weighed and consumed. The amount was checked. At this time, the weight loss of the bait (non-toxic bait) due to natural drying was obtained from the weight reduction of a container that was not tested for cockroaches, and was subtracted from the amount consumed. Table 3 shows the results.

[0116]

[Table 3]

From Table 3, it can be seen that the longer the length of the eaves 25, the greater the total number of cockroaches concealed.
The case of 5 mm was clearly large.

As a result of observing the behavior of the black cockroaches during the test, cockroaches that could not be contained in the container (2) or the container (3) lurked beneath the eaves 25. In addition, it was confirmed that the eaves 25 were effective for cockroach invasion, and that by increasing the length of the eaves 25, the latent performance could be enhanced.

Example 4 A container having the configuration shown in FIGS. 4 (a), (b) and 5 (hereinafter, referred to as container (A)) is used as a cockroach bait storage container for testing according to the present invention. It was used.

As a cockroach bait storage container for comparison, a container (hereinafter referred to as a comparison container (B)) having a structure in which all the eaves 54 (projections) were removed from the container (A) was used.

First, Vaseline (trademark) was applied to a portion 5 cm from the top of the inner wall of a transparent resin bat having a diameter of 30 cm and a height of 10 cm to prevent cockroaches from escaping.
Triangular prism-shaped shelters made of absorbent cotton and plywood moistened with water and bait for cockroach rearing were placed in bats.
Here, 25 males and 25 females of German cockroaches were released and left overnight to adapt to the environment.

Next, a cockroach poison bait containing fenitrothion (manufactured by Sumitomo Chemical Co., Ltd.) as an active ingredient was set in the container A and the comparative container B, and then the container A and the comparative container B were respectively placed in vats. Ground,
The number of knockdown insects over time was examined, and the knockdown insect rate (%) was calculated by the following equation: knockdown insect rate (%) = knockdown insect count / test insect count × 100. Table 4 shows the results.

[0123] Knockdown means that cockroaches slow down and cause symptoms such as convulsions or upside-down due to ingestion of poison bait. The number of knockdown insects indicates such symptoms. Indicates the number of cockroaches.

[0124]

[Table 4]

As is clear from Table 4, the knockdown of cockroaches was faster in the container A with the eaves 54 than in the comparative container B. From the above measurement results, even if the container body has the same configuration, by providing a protruding portion (eave) protruding outside the bottom wall and the side wall above the opening,
It was confirmed that the residence time in the container was long, the total latent number (probability of existence) was large, and the ingestion of poison bait quickly resulted in a high extermination effect, and that the effect appeared quickly.
