[Detailed description of the invention]

INDUSTRIAL APPLICATION FIELD The present invention relates to a fly attractant. Conventional technology Ribbon-shaped fly paper has been well known as a means of catching and killing flies, but conventional fly paper does not have the effect of actively attracting flies, and However, its killing effect is accidental and extremely inefficient. In recent years, it has been discovered that a yellow colored material or luminescent material has a fly-attracting effect, and attempts are being made to utilize this material in the above-mentioned fly paper and the like. However, according to the research conducted by the present inventors, the fly attracting effect of the above-mentioned yellow colored material or luminescent material is still not sufficient, and the fly extermination efficiency using this material is also not satisfactory. Problems to be Solved by the Invention It is an object of the present invention to provide a new fly attractant that eliminates all the drawbacks found in the above-mentioned conventional techniques and exhibits a particularly excellent fly attracting effect. Means for Solving the Problems According to the present invention, there is provided a fly attractant characterized in that it contains a pigment that exhibits a red color when formulated. As a result of extensive research, the present inventors have discovered that a formulation containing a reddish pigment when formulated as described above exhibits an outstanding fly attracting effect, and has hereby completed the present invention. It came to this. As used herein, "a pigment that exhibits a red color when formulated" means that when a component containing a pigment is formulated, the formulation exhibits a red color. Therefore, as a method of displaying the color of an object, display using the three attributes of hue, brightness, and saturation is commonly used, and the term "reddish" as used in the present invention means that the above-mentioned hue is red. means. This hue is
According to JIS standards (see JIS Z 8721), 2.5R~
It corresponds to a hue in the range of 2.5YR, preferably 7.5R to 2.5YR. The brightness and chroma of the red pigment are not particularly essential for the pigment used in the present invention, but usually the brightness is approximately 4 or more, preferably 5 or more, and the chroma is 7 or more. , preferably 6 or more. Further, in the present invention, the term "pigment" is interpreted in a broad sense and includes not only ordinary pigments (coloring substances) but also fluorescent substances and luminescent substances. Examples of pigments that exhibit a reddish color when formulated into formulations include the following. Γ Red No. 2 (Amaranth, Ashed Red 27, 1

[Table] Example 2 In Example 1, Methomyl (manufactured by DuPont, carbamate insecticide) was added as an insecticide component.
Each of formulation samples A2 to M2 with an insecticide concentration of 1% was obtained in the same manner except that 600 mg was added and mixed. The hue of each of the obtained formulation samples was the same as that of the corresponding samples A1 to M1 in Example 1 (see Table 1). Each of the preparations obtained in Example 2 above was subjected to the following attraction effect test. <Test> 60 g of each formulation was placed in a glass jar (diameter 15.5 cm) and placed in concentric circles on the floor of a fly-release laboratory at intervals of approximately 30 cm. House flies are released into the laboratory and allowed to roam. After a certain period of time, the number of dead insects in each chamber is investigated. The fly attracting effect of each preparation is calculated by dividing the number of dead insects in the shell containing it by the total number of dead insects in the laboratory (the total number of dead insects in all the shells). It is evaluated by calculating the percentage (%) of <Test> 10g of each formulation was placed in a plastic cup and placed in an outdoor glass room (1.45m x
The fly attracting effect of each preparation was evaluated in the same manner as in the <Test> except that the preparations were placed concentrically at intervals of approximately 20 cm on the floor surface of a 1.4 m long area. The results of each of the above tests are shown in Table 2 (Test) and Table 3 (Test), respectively.

【table】

[Table] Examples 3 to 6 In Example 2, the concentration of methomyl as an insecticidal ingredient in the formulation was kept at 1%, and the concentration of each of the following pigments in the formulation was 0.08% (Example 3, formulation No. 3), 0.16% (Example 4, Formulation No.
4), 0.5% (Example 5, Formulation No. 5) and 1.3%
(Example 6, Formulation No. 6) A fly-attracting insecticide of the present invention (in granular form) was obtained. The results of a fly attraction test similar to Example 2 for each of the obtained preparations are shown in Table 4 (Test) below.
and Table 5 (test) shows.

【table】

[Table] From the above tables, the following can be concluded.
In other words, the concentration and activity of dyes that are attractive to flies have not been considered in the past, but as shown in Table 4, the three dyes fluorescein, Yellow No. 5, and Sunset Yellow F are Both are dyes that exhibit fly-attracting activity, but the activity of the first two was found to be concentration dependent, while the activity of the latter was found to be independent of concentration. Furthermore, the relationship between the concentration and activity of the dye changes depending on the light conditions at the position where the preparation sample is placed, as seen from the comparison between Tables 4 and 5. It shows concentration dependence, but shows an inverse dependence tendency outdoors under natural light. From these facts, it is clear that the fly attractant of the present invention can exhibit a very effective fly attracting effect by arbitrarily selecting the dye used, its concentration, the place where the preparation is used, etc. be.
