Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for trapping the Japanese beetle, the object of which is to effectively capture the Japanese beetle known as an insect pest of turf and agricultural products. It is in.

[0002]

[Prior Art] Anomala rufocuprea is a medium-sized beetle belonging to the family Coleoptera, Scarabaeidae, distributed throughout Japan, and its adults damage various horticultural plants such as soybeans, adzuki beans and grapes, and leaves of vegetables. Known as a feeding pest. In addition, this beetle (Anomala rufocupre
The larvae of a) are also in the soil and damage crops, trees, and roots of herbs.

In recent years, damage to larvae on golf has become more serious, and intensive research has been conducted on measures against damage to turf on golf courses by these larvae. As a method for controlling this, conventionally, a method of mixing lime arsenate with a lime-bordeaux solution and spraying it, or spraying an organophosphorus insecticide such as MED, DDVP, EPN, and marathon has been used.

However, these pesticides have problems such as residual toxicity, and their use has been regulated in various ways in terms of environmental protection. In recent years, pheromones have been effective as a new means to replace pesticides. The new control methods are attracting attention.

On the other hand, the above-mentioned beetle (Anomala rufocupr)
The same damage is also considered to be a problem for the medium-sized beetle, Popillia japonica, which belongs to the same Coleoptera Scarabaeidae (ea).

[0006] Recently, in golf courses, Japanese beetles (Anomala rufocuprea) and Japanese beetles (Popillia)
As a method to capture japonica) at the same time, a method using a special trap with a pheromone agent is adopted. This method was a method in which a catcher equipped with a combination of the Japanese beetle pheromone agent and the Japanese beetle pheromone agent was appropriately installed at a place where it was necessary to capture.

[0007]

However, the above-mentioned method has a problem in that it is not possible to effectively capture the Japanese beetle (Anomala rufocuprea), which is harmful to the grass on the golf course. That is, in the method in which both the Japanese beetle pheromone agent and the Japanese beetle pheromone agent are used in the same trap to capture both pests, the Japanese beetle
(Llia japonica), although some capture effect can be obtained,
However, there was a problem that the number of arguments was small and it was not possible to effectively capture the Japanese beetle (Anomala rufocuprea).

[0008]

[Means for Solving the Problems] According to the present invention, a squirrel gane pheromone agent is installed in a place where it is necessary to capture squirrels (Anomala rufocuprea), and a squirrel beetle pheromone drug is installed in a location distant from the installation location of this squirrel pheromone drug. The above-mentioned conventional problems are solved by providing a method for capturing the above-mentioned beetle.

[0009] In the following, Anomala of the present invention
rufocuprea) capture method will be explained.

In the present invention, the Japanese beetle pheromone agent is placed away from the Japanese beetle pheromone agent to capture the Japanese beetle (Anomala rufocuprea).

[0012] As the agent for the female pheromone, the female pheromone, which is supported by paper, rubber, porous material, polymer, etc., or the pheromone contained in the tubular polymer, or higher Examples include those that have been processed with molecular films, etc., and then have sustained release.
It is not particularly limited.

[0012] Further, the bean beetle pheromone agent is not particularly limited, and a beetle beetle pheromone supported on paper, rubber, a porous body, a polymer or the like, or a tube-shaped polymer containing the pheromone. Alternatively, it can be suitably used by further processing it with a polymer film or the like and gradually releasing it.

In the present invention, as described above, the reason why the Himekogane pheromone agent is placed at a position apart from the Bean beetle pheromone agent at the location where the Anemona rufocuprea is required to be captured is that the same agent is used. When installed in combination with a trap, the effect of capturing the scorpion beetle (Anomala rufocuprea) cannot be obtained sufficiently, and by installing the stag beetle pheromone agent at a position distant from the syrup beetle pheromone agent, the effect of the squirrel crab pheromone agent is effective. It was discovered by the experimental knowledge obtained by the study of the present inventors that it is exerted and the trapping effect of the red beetle (Anomala rufocuprea) becomes extremely good.

[0014]

[Examples] The following is a description of the examples according to the present invention.
clarification of the effect of the capture method of omala rufocuprea).

[0015] As a beetle beetle pheromone agent, a product name manufactured by Nitto Denko KK
(R, Z) -5- (1-decenyl) dihydro-2 (3
H) -furanone) as a Himekogane pheromone agent,
Nitto Denko Co., Ltd. product name: Nitorua Himekogane (ingredient composition: (Z) -5-methyl tetradecenoate) was used, and these pheromone agents (P) were added to the Nitorula trap (1) shown in FIG. It was attached and used as a trap.

Examples 1 to 3 and Comparative Examples 1 and 2 ( ferro
When the distance between mon agents is 1 to 20 m) The bean gane pheromone agent was attached to the trap for the nitor lure, the mecogane pheromone agent was attached to another trap for the nitor lure, and Examples 1 to 3 and Comparative Example 1 were respectively performed.
~ 2 capture device. Two traps of each of these traps were placed at distance intervals according to Table 1 to test the attractive effect.

[0017]

[Table 1]

Comparative Example 3 ( when the distance between the pheromone agents is 10 cm ) The bean gane pheromone agent was attached to the trap for the nito lure, and the mecogane pheromone agent was placed on the opposite side of the beet gane pheromone agent in the same nitor lure trap (distance interval 10c).
It was attached to m) to obtain the trap of Comparative Example 3.

COMPARATIVE EXAMPLE 4 ( only for Himekogane pheromone agent)
Case ) A Himekogane pheromone agent was attached to the nitor lure trap to obtain a trap of Comparative Example 4.

Test Example 1 The traps of Examples 1 to 3 and Comparative Examples 1 and 2 were replaced with 7/1.
During the period from 0 to 9/15, 3 sets are installed on each side of the grass in the hole of the golf course, at a height of 1 m, for each distance interval, and capture of the Japanese beetle (Anomala rufocuprea) and the Japanese beetle (Popillia japonica). The average number was examined.

Test Example 2 The traps of Comparative Example 3 were set up at three places on the side of the lawn within one hole of a golf course and at a height of 1 m for a period of 7/10 to 9/15. The average number of traps of Anomala rufocuprea) and Japanese beetle (Popillia japonica) was investigated.

Test Example 3 The traps of Comparative Example 4 were set up at three places on the side of the lawn within a hole of a golf course and at a height of 1 m for a period of 7/10 to 9/15. The average value of the number of captured Anomala rufocuprea) was examined.

The results of Test Examples 1 to 3 are shown in Table 2.

[0024]

[Table 2]

As is clear from the above test example, when two pheromone agents were attached to the same trap (distance interval 10 cm, comparative example 3), the stag beetle (Anomala rufo) was used.
cuprea) could hardly be captured.

In addition, the case of the Himekogane pheromone agent is installed at a distance of 5 m or more from the bean bug (Cases 1 to 3) and the case of being installed at a distance of 5 m or more (Comparative Example 1).
It was found that there was a marked difference in the number of Japanese chafers (Anomala rufocuprea) from ~ 2).

Furthermore, when the Himekogane pheromone agent is placed at a distance of 5 m or more from the Bean beetle pheromone agent (Examples 1 to 3) and when the Himekogane pheromone agent is placed alone (Comparative Example 4), the Anemala rumen (Anomala ru) is used.
It was found that the capture effect of focuprea) was almost unchanged.

Next, since each of the above tests was carried out within one hole of the golf course, there is a possibility that attraction may be hindered by the installation of a large number of traps. Therefore, as shown in FIG. The same test as above was carried out by setting the hole at a distance of 10 m or more from the trap and changing the hole for each test.

The results are shown in Table 3.

[0030]

[Table 3]

As is clear from Table 3, it was found that the distance at which the attraction-inhibition between the Himecogane pheromone agent and the Japanese bean claw pheromone agent occurs was within about 1 m. Therefore, when these pheromone agents are used in combination, the distance between the traps is set to 1 m or more, so that the Japanese chafer (Anomala rufocuprea) can be effectively trapped.

[0032]

INDUSTRIAL APPLICABILITY As described above, the present invention provides
omala rufocuprea) is installed in a place that requires capture, and the method of capturing Anomala rufocuprea is simple because it is installed in a place away from the place where this pheromone pheromone drug is installed. It is possible to efficiently capture the beetle, Anomala rufocuprea, which is an insect pest of agricultural crops, and also the beetle, Popillia japonica, at the same time.
