DISCLOSURE OF THE INVENTION The present invention provides a cockroach attractant which has an unprecedented powerful attracting effect on various cockroaches. As the 3-hydroxy-2-alkyl-4-pyrone in the present invention, for example, 3
-Hydroxy-2-methyl-4-pyrone (malt-
), 3-hydroxy-2-ethyl-4-pyrone (ethylmaltol) and the like. Methylcyclopentenolone is 2-hydroxy-3-methyl-
2-cyclopenten-1-one (Perfume and Flavor C
Chemicals (Aroma Chemicals), Steffen Arctender) and its derivatives include methylcyclopentenolone butyrate, methylcyclopentenolone-3, 4-dioxy-5-methoxy-iso-propylbenzene, methylcyclopentenolone Compounds such as propionate can be mentioned.

[0005] Conventionally, cockroach repellents include insecticide preparations such as aerosol type, spray type, fumigation / fumigation type, poison bait type, and application type, and trapping type using an adhesive. In these pesticides, attractants are used to improve the insecticidal effect and the trapping efficiency. The cockroach attractant has a shape that is easily used depending on the type of these pesticides. That is, the cockroach attractant is processed and used in the form of powder, liquid (aqueous or oily), paste, and the like, and further, into the form of granules, tablets, bags packed with nonwoven fabric, and the like. The cockroach attractant of the present invention can be used as an attractant in any of the above forms and a cockroach repellent.

[0006] The cockroach attractant of the present invention can be used either directly or in admixture with one or more of the above compounds. When used in a solid type, usually, the attractive active ingredient of the present invention, flour, bran,
It can be used as a mixture with sugars such as rice bran, glucose and fructose, bread, potato, starch, yeast powder, corn starch, and other feeds such as animal feed. When used in a liquid form, it can be mixed with an organic solvent such as glycerin, alcohol, ether, animal oil, vegetable oil, water and the like.

The content of the cockroach attractant in the preparation is usually 0.01 to 5% by weight, preferably 0.1 to 3.2% by weight. If it is less than 0.01% by weight, a sufficient attraction effect cannot be obtained. Further, even if it exceeds 5% by weight, no improvement in the effect corresponding to the increase in the added amount can be expected. The concentration of the pesticide is not particularly limited depending on the type of the pesticide, and can be dealt with by adjusting the absolute amount of the present attractant. Hereinafter, the present invention will be described in more detail by way of examples.

【Example】

Example 1 A 34 cm × 26 cm length and width shown in FIG.
White margarine is applied to the upper part of the inner peripheral wall of an open box-shaped plastic container having a height of 11 cm, and a shelter for hiding cockroaches at one end of a longitudinally central portion of the container. The container for drinking water and the container for solid feed were arranged on the opposite side of the shelter with the container for drinking water interposed therebetween. Four such experimental containers were prepared, and 30 male and female adult German cockroaches were released into each of the four containers, for a total of 60 animals, and were acclimated to the environment for 7 to 8 hours. As the solid feed, a solid feed for breeding small animals (manufactured by Oriental Yeast Co., Ltd.) was given. Next, the container for solid feed was removed, and two traps (9.5 cm in diameter, 4.6 cm in height) coated with white margarine were arranged side by side at an appropriate interval, and one of the traps was placed on one side of the trap. As a test plot, methylcyclopentenolone as a powder auxiliary,
0.01%, 0.1%, 0.2%, 0.4%, 0.8
%, 1.6%, 3.2% and 10% of the cockroach attractant mixed at a weight ratio of 1% each were placed in the trap of the test plot. In addition, as a powder auxiliary, sugar 35
%, A 65% cone starch mixture. The remaining trap was used as a control, and 1 g of the powder auxiliary agent not mixed with the cockroach attracting component was placed in the trap.

The test container is heated at a temperature of 25 to 30 ° C.
It was left overnight under no lighting conditions from 5:00 pm to 8:30 am the next morning. Thereafter, the number of German cockroaches captured by each trap was counted for these four test containers. In addition, in order to eliminate the experimental error due to the location of both traps in the test plot and the control plot, the same experiment was performed with the locations of both traps exchanged. From the results of these experiments, the effect of the cockroach attractant was evaluated using the ratio of the total number of German cockroaches captured by the test trap to the total number of cockroaches captured by the control trap as the attracting ratio.
Table 1 shows the results. Table 1 shows that the cockroach attractant of the present invention has a good attracting effect in the range of 0.1% to 3.2%.

[0010]

[Table 1]

Example 2 Methyl cyclopentenolone was changed to maltol,
The test was performed in the same manner as in Example 1. Table 1 shows the results.
Shown in Example 3 A test was carried out in the same manner as in Example 1 except that methylcyclopentenolone was changed to ethyl maltole. Table 1 shows the results.

Example 4 A test was conducted in the same manner as in Example 1 except that methylcyclopentenolone was changed to a mixture of maltol and methylcyclopentenolone in a weight ratio of 3/5. Table 1 shows the results. As is evident from Table 1, when maltol and methylcyclopentenolone are used in combination, the attraction effect is greatly improved as compared with the case where each is used alone. Example 5 A test container was replaced with a container having a size of 100 cm × 50 cm and a height of 25 cm. Silicon oil was applied to the upper part of the inner wall, and each container of a shelter, a container for drinking water, and a container for solid feed was changed from FIG. 2 were placed in the test containers shown in FIG. 2, and eight male and female adult black cockroaches were released into each test container, for a total of 16 animals. An attraction test was performed in the same manner as in Example 4. The trap has a diameter of 13c.
m and a height of 7.7 cm were used. Table 1 shows the evaluation results. Example 6 A test was performed in the same manner as in Example 1 except that methylcyclopentenolone was changed to a mixture of maltol, methylcyclopentenolone, and ethylmaltol in a weight ratio of 1/2/1. . Table 1 shows the results.

Example 7 The test plot was the same as in Example 4, and the control plot contained fish meal 13
Parts, 35 parts of soy flour, 8 parts of sucrose, and 44 parts of starch (each part by weight) were mixed to make a powder form, used as a comparative cockroach attractant, and mixed at the same mixing ratio as in the test plot, as in Example 1. Was tested. Table 1 shows the results. Table 1 shows that the cockroach attractant of the present invention is more effective than the conventional one.

Example 8 A test was conducted in the same manner as in Example 7 except that honey was used as the comparative cockroach attractant. Table 1 shows the results. Example 9 The same test as in Example 7 was performed except that the cockroach attractant was fish meal. Table 1 shows the results.

Example 10 A cockroach attractant obtained by mixing maltol, methylcyclopentenolone and the powder auxiliary in a weight ratio of 1.5 / 2.5 / 6.0 was used to kill about 30% of a commercially available boric acid. 0.5%, 0.1%, to the insecticide (dango borate) contained as an ingredient.
75%, 1.0%, 2.0%, 3.0% and 4.0%
The test was carried out in the same manner as in Example 1 except that the mixture obtained so as to give a test group, and dango borate containing no attractant was used as a control group. Table 2 shows the results. It can be seen that the attractant of the present invention also exerts an excellent attractant effect when used in combination with an insecticide containing boric acid as an insecticidal component.

Example 11 A test was conducted in the same manner as in Example 5 except that dango borate using the cockroach attractant used in Example 10 was used as a test group, and dango borate containing no attractant was used as a control group. Carried out. Table 2 shows the results.

Example 12 Silicone oil was applied to the upper part of the inner peripheral wall of the test container used in Example 5, and four shelters, a drinking water container, and a container containing solid feed were prepared. 30 male and 30 female adults each were released, and a total of 60
Acclimated to time environment. Thereafter, the container containing the solid feed was removed and replaced with a test group and a control group.
A commercially available sticky cockroach catcher (cockroach hoi-hoi) was placed on each of them, and the cockroach-inducing component used in Example 4 was added to the catcher in the test plot at 0.5% in a cone starch.
75%, 1.0%, 2.0%, 3.0% and 4.0%
The cockroach attractant mixed by weight ratio was packed in a non-woven bag and placed, and the cockroach hoi-hoi attractant was placed as it was in the trap in the control section. This test container is
5:00 pm to 8:03 am the next day under no lighting conditions at a temperature of ℃
After standing overnight until 0 minutes, the number of German cockroaches captured by the sticky cockroach trap in each test container was counted. Further, a test was performed in which the positions of the test plot and the control plot were interchanged in the same manner as in Example 4, the total number of captured cattle was obtained, and the attracting ratio was calculated. Table 2 shows the results.

Example 13 Example 12 is a German cockroach, which is made into a black cockroach, and the number of male and female adults is 8 each, that is, 16 in total.
An attraction test was carried out in the same manner as described above. Table 2 shows the results. Example 14 A test was carried out in the same manner as in Example 10, except that the dango borate used in Example 10 was replaced with a commercially available poison bait (combat) containing hydramethylnon as an insecticidal component. Table 2 shows the results. Example 15 A test was performed in the same manner as in Example 14, except that the German cockroach was replaced by a black cockroach and the test container was the same as that in Example 5. Table 2 shows the results.

[0019]

[Table 2]

Example 16 Two test containers of Example 1 were prepared and used as test containers A and B, respectively. A shelter, a drinking water container, and a container containing solid feed were placed in each case, and 30 male and female adult German cockroaches were released, each of which totaled 60 animals, and were acclimated to the environment as in Example 1. Example 4 was added to test container A.
And a container containing a cockroach-inducing insecticide containing 2.0% of the cockroach-inducing component used in the above and a poison bait (combat) containing hydramethylnon as an insecticidal component, and a container containing solid feed. And a test plot. In the other test container B, a container containing the insecticide without a cockroach attracting component, and a container containing solid feed,
A control group was arranged in the same manner as the test container A. The number of dead German cockroaches in these two test containers A and B was 5
Observed for days. Further, in order to eliminate errors due to locations, an experiment was conducted in which the position of the container containing the insecticide and the position of the container containing the solid feed were exchanged in the same manner, and the mortality of both cockroaches was evaluated from the total number of dead cockroaches. Table 3 shows the results.

[0021]

[Table 3]

Example 17 As a cockroach attracting insecticide, a paste-like poison bait containing hydramethylnon as an insecticidal component, in which methylcyclopentenolone alone was mixed in the proportions shown in Table 4, was used as a cockroach. An attraction test was performed in the same manner as in Example 5 except that a butter trap was used as the trap. Table 4 shows the results.

[0023]

[Table 4]

[0024]

The cockroach attractant of the present invention is harmless to the human body, and has a greater cockroach attracting effect than conventional cockroach attractants. As a trap attractant,
It can be used in combination with other insecticides, and is effective for controlling cockroaches. In particular, when methylcyclopentenolone is used in combination with maltol and / or ethyl maltol, a favorable cockroach attracting effect is exhibited.
And in this case, about 0.2-3% of the total of the attracting active ingredients
Within the range, an extremely good attracting effect can be obtained.
