Description

  The present invention relates to a pest attracting agent, a pest attractant and a pest attracting method.

  Conventionally, attracting insecticides such as poison baits have been used to control pests such as cockroaches, flies, ants, etc., and attractants have been used to further increase the controlling effect. The attracting insecticide is preliminarily installed in a range where pests inhabit and act, and is for controlling the pests by attracting the pests and ingesting poison baits or capturing them with a trap.

  Attracting insecticides such as poison baits are used for a long time in any place, and with conventional attracting insecticides, the active ingredients and attractants change and dry after a long time after installation. In some cases, a sufficient control effect could not be obtained. Therefore, various studies have been made to maintain the effect of the attracting insecticide for a long period of time. For example, an aliphatic polyhydric alcohol such as glycerin is added as a volatilization inhibitor of the volatility attracting component (for example, the following patents) For example, it is known to use wax or petrolatum as a base material (for example, see Patent Document 2 below) for durability and attraction effect.

That's fine. According to the pest attracting method according to the present embodiment, by using a tetrasaccharide having an action of sustaining the pest attracting effect, the decrease in the pest attracting effect due to the passage of time is sufficiently suppressed and used for a long time (for example, at least Since the effect of attracting pests by 2 weeks) can be remarkably improved, the effect of attracting pests can be maintained for a long time.

  Hereinafter, the present invention will be described by way of examples. However, the present invention is not limited to these examples.

[Sample preparation]
As shown in Table 1, 92.5 g of a composition comprising dinotefuran, black vinegar, Shaoxing liquor and water is added to 7.5 g of a water-absorbing polymer (modified polyalkylene oxide), and the water-absorbing polymer is swollen to form a gel granular preparation. Got ready. Next, 40 g of the above preparation was placed in a hemispherical top-opened container (capacity 95 mL) having a diameter of 7.5 cm and a height of 3.4 cm to serve as a control sample. In addition, the unit of content in Table 1 is “mass%”.

  Moreover, as shown in Table 1, 92.5 g of a composition comprising dinotefuran, black vinegar, Shaoxing liquor, sugar and water was added to 7.5 g of a water-absorbing polymer (modified polyalkylene oxide), and the water-absorbing polymer was swollen to each. A gel granular formulation was prepared. Next, 40 g of the above preparation was placed in a hemispherical container (capacity 95 mL) having a diameter of 7.5 cm and a height of 3.4 cm to obtain test specimens (Example 1, Comparative Examples 1 to 5).

[Attraction test]
About 100 Drosophila melanogaster were released as test insects in the test space (1.8 m × 1.8 m × 1.8 m). Next, as shown in FIG. 1, a total of two control specimens are installed at each position A on the bottom surface in the test space, and one test specimen immediately after preparation is measured at each position B on the bottom face. Two were installed. Three hours after the container was placed, the number of test insects present in the container was measured to obtain a first measurement value.

  Next, in the first measurement, the position of the specimen is changed (the control specimen is placed at position B and the test specimen is placed at position A), and the number of test insects is the same as in the first measurement. Was measured, and a second measurement value was obtained. Further, the first measurement and the second measurement were repeated, and a third measurement value and a fourth measurement value were obtained.

  The same test was performed on test specimens obtained after preparation and left standing at 25 ° C. for 2 weeks.

From the results of each test, the attraction ratio based on the attracting argument of the control specimen was calculated by the following formula. The results are shown in FIG.
Attraction ratio = total number of individuals present in the test sample container / total number of individuals present in the control sample container

As shown in FIG. 2 and Table 2, in the test using the test sample immediately after preparation, the attracting ratio was 0.9 to 1.2 in both Example 1 and Comparative Examples 1 to 5, and the control sample. It was the same as the attracting effect.
On the other hand, in the test using the test specimen obtained by standing at 25 ° C. for 2 weeks, the attracting ratio of Comparative Examples 1 to 5 is 0.9 to 1.3, and the attracting effect is similar to that of the control specimen. On the other hand, the attracting ratio of Example 1 was 1.8, showing a large difference.
Therefore, the pest attractant of Example 1 formulated with tetrasaccharide has little effect on the attracting effect immediately after preparation, but the attracting effect after a long time (after standing for 2 weeks) is more than that of the comparative example. Obviously, it was confirmed that tetrasaccharides have the effect of sustaining the attracting effect.
Therefore, it has been confirmed that the present invention can sufficiently suppress the decrease in the pest attracting effect due to the passage of time and can significantly improve the pest attracting effect by using for a long time as compared with the conventional one.
