Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD [0001] The present invention relates to an attractant characterized by exhibiting an excellent attracting property to adult pearl worms.

[0002]

2. Description of the Related Art Luminescent Species (Scientific name: Anomala l
ucces balion) is one of the omnivorous agriculturally important pests in which larvae damage the underground parts of grass and grass, and adult adults damage many leaves of broad-leaved trees. Adult insects of this insect fly over a relatively wide area, and since larvae live in the soil, it is difficult to confirm both, and it is difficult to directly contact the chemicals. is there. That is, conventionally, the control of this pest has been carried out by carbosulfan, diazinon, MP for larvae.
Soil admixtures such as P granules have been used, but it is extremely difficult to maintain the control effect for a long period of time because these agents have low residual effects, and the agents penetrate deep into the soil. Since it has to be done, the amount of spraying also increases, so environmental problems are likely to occur. In recent years, research on pheromones and attractants has been conducted as one of the control methods that do not use insecticides, and traps using these as attractants are used for the investigation and trapping of pests.

[0003]

Among the attractants used in the above traps, there are specified attractants for Douganebu buoy (Patent No. 2545179, Patent No. 3085894), attractants for leaf beetle Scarab beetle (Patent No. 2520374), and the like. Although an attractant for the scarab beetle is known, an attractant for the scarab beetle has not yet been created, and creation of an attractant for the scarab beetle has been strongly demanded.

[0004]

Means for Solving the Problems In order to solve the above-mentioned problems, the present inventors searched a wide range of substances having an attracting activity against Lucifer, and as a result, other substances known as attractants for scarab beetles. From among the above, we have newly found a group of compounds that have a very high attracting effect on the pearl oyster.

The present invention has the following configuration.

(R, Z) -5- (1-octenyl) oxacyclopentan-2-one, (R, Z) -5- (1-
Decenyl) oxacyclopentan-2-one, (Z)-
3-hexen-1-ol or 1,2-dimethoxy-
An attractant for an adult lucid beetle, which contains at least one or a plurality of compounds selected from 4- (1-propenyl) benzene. Preferably, (R, Z) -5
It is characterized by containing one or more compounds selected from-(1-octenyl) oxacyclopentan-2-one and (R, Z) -5- (1-decenyl) oxacyclopentan-2-one. An attractant for adult pearlescent beetles.
Alternatively, (Z) -3-hexen-1-ol, 1,2
-An attractant for the pearl worm, which contains at least one or a plurality of compounds selected from dimethoxy-4- (1-propenyl) benzene. More preferably, one or more compounds selected from (Z) -3-hexen-1-ol and 1,2-dimethoxy-4- (1-propenyl) benzene, (R, Z) -5- (1- Octenyl) oxacyclopentan-2-one and (R, Z)-
An attractant for adult pearl worm, which comprises 5- (1-decenyl) oxacyclopentan-2-one.

[0007] These compounds are easily available as attractants for scarab beetles other than pearlescent beetle, inexpensively available as a raw material for fragrances, or easily synthesized from these reagents by a conventional method. Is a substance,
The present invention is not particularly limited, and those obtained by any means can be used.

The attractant according to the present invention can be prepared by using these compounds, and using the formulation technique which is usually applied in the preparation of the attractant. For example, these compound groups as they are, or alcohol, ether, acetone, dichloromethane, toluene,
After diluting with an appropriate solvent such as hexane, ethyl acetate, pentane, etc., adsorb it on an appropriate carrier, such as various synthetic polymers / rubber, or impregnate it with cotton, non-woven fabric, paper, etc. It can be formulated by being enclosed in a molded article of molecular material.

The content of the active ingredient in these attractants can be appropriately determined according to the environment in which it is used, but usually the amount of the active ingredient per formulation is 0.1 mg to 20 in the whole compound group.
g, preferably 1 mg to 5 g. Moreover, the compounding ratio of the compound group contained as an active ingredient can be compounded at an arbitrary ratio.

The attractant of the present invention can be used as an attracting source for insect traps of any form such as basin type, slide type, adhesive type and the like, and an insecticide such as diazinon having a contact poisoning effect is applied. It is also possible to impregnate the cut wood pieces, resin pieces, etc., and use them for attracting and killing. The installation place is, for example, a place where radiant glisters occur, for example, a golf course, a grass field such as a park, an orchard, or the like, but is not limited thereto. Next, the present invention will be described more specifically with reference to examples.

500 mg of 1,2,2-dimethoxy-4- (1-propenyl) benzene was impregnated with g, 1,2-dimethoxy-4- (1-propenyl) benzene and then sealed with a polyethylene film to prepare a preparation (Preparation 3). These formulations were attached to a dry sliding trap (trade name Winspack, manufactured by Japan Tobacco Inc.), and a trap without an attractant was set as a control for 10 days. Three traps were used for each preparation, and the average number of traps was investigated.
