Description

[Detailed description of the invention]

(Industrial Application Field) The present invention relates to a cockroach attractant. (Prior Art) Cockroaches are important pests not only as pests of food and books, but also as transmitters of pathogens and intermediate hosts of helminths. In recent years, advances in heating equipment for buildings and homes have made it possible for cockroaches to grow in the winter, and as food has become more abundant, cockroaches have proliferated significantly and their control has become a problem. Conventional methods for controlling cockroaches include placing poison bait containing insecticides in infested areas and trapping them with paper traps coated with adhesive, but these methods have not been sufficiently effective. I can't get it. (Problems to be Solved by the Invention) Various cockroach attractants have been proposed to enhance these effects, but at present no one suitable for practical use has been found. (Means for Solving the Problems) The present inventor has conducted various studies in view of the current situation, and as a result, has discovered an extremely effective and practical cockroach attractant, which is:

[Formula] (R ₁ = CH ₃ , C ₂ , H ₅ , R ₂ = H, CH ₃ , C ₂ H ₅ ) and α-oxy acids and their esters;

α-ketol represented by [Formula] (where R = H, CH ₃ ) and

Consists of one or more selected from [Formula]. (Example) Next, an example of the present invention will be described. The present inventor has tested the attracting effects of various substances on cockroaches, and those represented by the above chemical formula, such as lactic acid, hydroxybutyric acid, its ethyl ester, acetol, acetoin, and pyrugic acid, are particularly effective. I discovered that. The cockroach attractant of the present invention can be prepared by adding one or more of the above chemical substances as is or mixing them with other auxiliaries in the form of liquid, solid, paste, etc. , used in combination with insect traps to kill insects or promote insect trapping. The auxiliary materials are
Solid powders such as wheat flour, bran, rice bran, fish meal, sugar, bread, potatoes, starch and other inert mineral carriers such as talc; liquids such as water, organic solvents such as glycerin and alcohol, oils and fats, surfactants, etc. It is. This agent is mixed with the powdered auxiliary material mentioned above, or the preparation liquid dissolved or dispersed in the liquid auxiliary material is placed in an open container, or it is adsorbed or applied to a base material such as paper or cloth. Install it in an appropriate location. Preferably, it is installed near or inside a trap for trapping, or at or near a place where the fungicide is applied, to improve the efficiency of trapping or killing insects. Moreover, an insecticide can be added to the above-mentioned auxiliary material to give it an insecticidal effect, and a poison containing the liquid or solid agent may be placed in a place where cockroaches are infested to attract and kill them. This agent strongly attracts cockroaches even in small amounts, but
The amount used should be 1 mg or more when used as is, and the absolute amount should be 1 mg or more when used in combination with an auxiliary material. Next, the attracting effect of the cockroach attractant of the present invention was confirmed by the following comparative experiment. Experimental Examples 1 to 6 Vaseline was applied to the upper part of the inner peripheral wall of a box-shaped plastic container 1 measuring 50 x 100 x 30 (n) cm as shown in Fig. 1, and a shelter 2 contaminated with feces was placed on the 1 side of the bottom. A large number of containers were prepared in which a container 3 containing water was installed in the center, and the experimental examples shown in Table 1 were carried out as follows. That is, in carrying out the example, four containers prepared as described above were used, and in each container, German cockroaches were placed as test insects, three adult male insects, three adult female insects, and three to three female adult insects.
After releasing 45 5th instar larvae (15 each) and conditioning them, adhesive traps 4 and 5 were placed on the left and right sides of the bottom of the container 1, and the inside of one of the traps 4 was filled with the agent. 20 mg of acetol was placed on this to serve as a test area, and the other Trap 5 was left with nothing and used as a control area, at a temperature of 25-30°C and in the dark overnight (from 5pm to 8:30 the next day). ) The number of cockroaches captured in each trap 4 and 5 was investigated. Furthermore, in order to eliminate differences in the experiment due to location, four containers were prepared in which the locations of the test trap containing the drug and the control trap containing nothing were exchanged, and the same tests as described above were conducted on these containers. Summer. As a result, the results shown in Experiment Nos. 1 and 2 in Table 2 were obtained. Containers No. 1 and 1' show containers in which the positions of the test area and the control area were exchanged, respectively. Experiments were carried out in the same manner as in Experimental Example 1, but as shown in Experimental Examples 2 to 6 in Table 1, the types of insects used in this example and the types of test insects were changed. However, in the case of black cockroaches, Japanese cockroaches, and American cockroaches, a total of 12 adult male insects, four adult female insects, and four 5th to 7th instar larvae were released for the experiment. The respective experimental results are shown in Tables 3-7. X shown in each of Tables 2 to 7 indicates the capture ratio of the total number of catches when using this agent to the total number of catches in the control area.

[Table] As is clear from Tables 2 to 7 showing the results of Experimental Examples 1 to 6 above, the use of the attractant of the present invention has a significantly high attracting effect regardless of the type of cockroach, and It was recognized that it has a trapping effect. Experimental Examples 7 to 10 In the same manner as Experimental Examples 1 to 6, 1 g each of sugar, fishmeal, and insect feed were placed in the control traps as shown in Table 8 below, and the attractant of the present invention was placed in the test traps. Experiments were conducted on various cockroaches using a mixture of sugar, fishmeal, and insect feed in the proportions shown in Table 8, and the results shown in Tables 9 to 12 were obtained.

[Table] As is clear from the experimental results in Tables 9 to 12 above,
It has been found that even when the attractant of the present invention is used in combination with a suitable auxiliary material, it has a remarkable effect of attracting cockroaches, resulting in an increase in the amount of cockroaches captured. Next, an experimental example of the attracting and killing effect when the attractant of the present invention is used mixed with poisoned bait will be explained. Experimental example 11 Prepare two plastic vats 1 of 34 x 26 x 11 (n) cm as shown in Figure 2 a, apply petroleum jelly to the upper part of the inner peripheral wall of each vat 1, and apply petroleum jelly to the bottom 1 side. A water container 3 was placed in the center of the shelter 2 and the other side, and a total of 60 German cockroaches (20 each) were released, including 20 male adults, female adults, and 3rd to 5th instar larvae. After conditioning, 5 g of fish meal and corn starch were added. 3.8g, boric acid 1g,
Acetoin 0.1g and lactic acid ethyl ester 0.1
Place 5 g of each half of 610 g of poisonous bait mixed with 610 g of poison bait on the bottom of each of the two buckets 6, on the left side of the water container 3 in the center, and place the mixed insect feed 7 on the right side at an equal distance. The number of dead insects and the amount of food eaten were investigated economically for each of the two containers prepared for the test plots. On the other hand, without adding the attractant of the present invention, fishmeal 5
A control container (No. 2) was prepared in the same manner as shown in FIG. The number of dead insects eaten and the amount of food consumed were examined over time for each sample (shown in Figure b). The results are shown in Tables 13 and 14.

[Table] As is clear from Tables 13 and 14 above, when the attractant of the present invention is mixed with poisoned bait, the efficiency of killing insects by poisoned bait increases in a shorter time due to its attractant effect compared to when it is not mixed. I know it will be done. (Effect of the invention) As described above, according to the present invention, since the agent specified in the claims is used as a cockroach attractant, it can be used as a trap such as an adhesive trap, poison bait, insecticide, etc. When used in combination, it has the effect of increasing the insect trapping or killing efficiency.
