Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fly attractant comprising, as an active ingredient, an ingredient obtained by squeezing the skin of bamboo shoots or squeezing or extracting with a solvent, and a method for producing the same.

[0002]

2. Description of the Related Art Fly flies occur from livestock houses, poultry houses, refuse disposal plants, etc., and are not only inconvenient in terms of hygiene and work, but also give a great deal of discomfort to residents in the vicinity. Such adult larvae of flies have been exterminated using insecticides and growth regulators. However, adults have great flight ability,
Since the larva infiltrates the organic matter that is the bait, the delivery efficiency and the effect of these drugs are often insufficient.

[0003] Therefore, it has been practiced to attract adult flies to efficiently take in insecticides or to attract and trap them in traps. It is known that the solvent extractable component of the so-called bamboo shoot edible portion attracts flies (for example, Japanese Patent Application No. 229327/1990), but it is difficult to obtain raw materials at low cost, and it is a suitable solvent. There was a great deal of difficulty even in the operation of extraction filtration with water.

[0004]

DISCLOSURE OF THE INVENTION The present invention provides an inexpensive attractant obtained from bamboo shoot skin for controlling adult flies and a method for producing the same.

[0005]

Means for Solving the Problems As a result of intensive search for a substance that attracts flies, the present inventors have surprisingly found that bamboo shoots which can be said to be waste produced by-product when producing canned bamboo shoots. The present inventors have found that a solvent extract of the skin of the husk shows excellent attraction to adult flies and that the extraction and filtration operation is extremely easy, thus completing the present invention.

[0006]

DETAILED DESCRIPTION OF THE INVENTION The fly attractant of the present invention uses bamboo shoot skin and is squeezed as it is, or squeezed or extracted using a solvent.

The bamboo shoots used in the present invention are Gramineae (Gramin).
eae), a species included in the subfamily Bambu-soideae (Bambu-soideae), and belongs to, for example, Moso bamboo, wasp, otake, nemagaridake or nemagaritake.

As the solvent for the extraction, a commonly used anhydrous or water-containing organic solvent or water is used, and water, water-containing methanol and water-containing ethanol are particularly preferable.

The attracted flies are species of the order Diptera, Muscidae and Musca domestica, such as the housefly (Musca dome).
stica), the maggot fly (Fannia canicularis), and the house fly (Muscina stabulans).

[0010] In the production method of the present invention, only the bamboo shoot skin is collected and, for example, shredded and squeezed as it is, or water or hydrated ethanol is added in an amount equal to or three times as much as that of the skin, stirred, and then squeezed. An extract that strongly attracts flies can be obtained by simply filtering the juice. It is easy to remove the precipitated components by further standing, heating, or filtering, or to add a preservative such as sorbic acid. In particular, the filtration step is several times more efficient than the extraction operation involving the edible portion of bamboo shoots. The extract can be concentrated, dried, or fractionated to produce a product. On the other hand, it is also preferable to obtain a simple and effective product as it is or by adding water or the like.

[0011]

According to the present invention, the extract of bamboo shoot skin is
It shows an excellent attracting effect on flies, and is used for a fly control method using a fly control agent and an attractant trap to which the present component is added as an attractant. The method for producing the present attractant is simple and efficient, and in particular, the juice filtration step can be performed in a short time, and is overwhelmingly inexpensive.

When using the product, it is preferable to adjust the preparation by a method well known in this field and use it.

For example, propetanphos, azamethiphos,
Water of organophosphorus pesticides such as chlorpyrifosmethyl, diazinon, trichlorfon, fenitrothion, dichlorvos, pyrethroid pesticides such as arethrin, permethrin, chryslon, etofenprox, carbamate pesticides such as carbaryl, propoxur, BPMC The preparations, emulsions, microcapsules and other preparations are optionally diluted with water, and the components of the present invention are added thereto. The resulting preparation is used as a spray by spraying with a sprayer or as an attracted insecticide in an attracting trap. The amount of the component (extract) used in the present invention is 0.01 to 10% by weight (preferably 0.05 to 1%) with respect to a diluted solution of the insecticide (for example, containing about 0.2% by weight of the insecticide component). % By weight).

When used in an attracting trap, it is preferable to prepare the preparation using an auxiliary agent. As an auxiliary agent, for example, sugar, milk, skim milk powder, livestock and experimental animal feed, starch, flour, rice bran, bran, corn flour, fish meal, food feed such as edible vinegar, liquor, edible oil, methanol, ethanol, propanol , Butanol, alcohols such as octanol, fuel oil, machine oil, surfactants, papers, fibers and the like. Mixing, dissolving, or containing the components of the present invention into these to form a formulation,
Use by setting in an appropriate trap. In addition, heat, wind, and the like can be used for the divergence of the attractant component, and a synergistic effect of the attractant can be obtained by using the attractant component together with another attractant such as light or sex pheromone. The amount of the component (extract) used in the present invention is a dilute solution of the insecticide (for example, about 0.1% by weight of the insecticide component).
Content) in a weight ratio of 0.05 to 10% by weight (preferably 0.1 to 2).

The form of the fly trap or fly paper is included as the attracting trap. That is, it is prepared by adhering the adhesive substance and the component of the present invention on an appropriate film or plate. Further, the attracting composition containing the component of the present invention can be spray-applied to a commercially available fly collecting ribbon or the like for use.
