Description

Drosophila attraction and killing composition, and Drosophila eliminator using the same {A COMPOSITION FOR ATTRACTING AND KILLING DROSOPHILIDAE, AND AN APPARATUS FOR REMOVAL OF DROSOPHILIDAE USING THE SAME}

The present invention relates to a composition for attracting and killing fruit flies and a fruit fly eliminator using the same.

Flies, including fruit flies, are very harmful because they cause diseases (especially infectious diseases) by transferring various pathogens to humans or animals directly or indirectly through food or drinking water.

Conventionally, in order to kill an emergency pest such as fruit flies, the pest control agent is sprayed directly, or a sticky adhesive sheet is used, or the pest control agent is mixed with food to attract pests and die, or ultrasonic or A pest control device using a magnetic field was used. However, such a conventional pest control method has a high risk of causing harm to the human body and also has a disadvantage of adversely affecting environmental hygiene.

On the other hand, Japanese Patent Registration No. 1,303,878 discloses, `` Emergency pest control that can be used by injecting an agent to attract emergency pests such as fruit flies and attracting emergency pests from the opening to the inside. The design regarding the container for containers is disclosed. In addition, Korean Utility Model Publication No. 306,654 describes a fly catcher characterized by capturing a bottle in the shape of a lot and feeding food into the center of the bottle to capture and rescue flies such as fruit flies. It is described. In addition, Japanese Laid-Open Patent Publication No. 2003-206211 discloses "water and sugar liquids (sugars used for the sugar liquid are one or two or more sugars selected from the group consisting of sucrose, glucose and fructose, for example) and yeast ( For example, a fly attractant composition comprising one or two or more yeasts selected from the group consisting of baker's yeast, sake yeast, beer yeast, and alcohol yeast. Japanese Laid-Open Patent Publication No. 2003-206211 also discloses that "(i) a low-traffic attractant prepared for accommodating beer, which is a small Paris attractant, and (ii) A small fly trap, which is composed of a collector disposed at or near the top opening and having an adhesive trapping surface. In addition, Japanese Laid-Open Patent Publication No. 2002-205904 discloses "1) sugars (e.g., sugar, glucose, fructose, etc. to lower the active moisture level) and gelling agents (e.g., konjac powder, cardlan, etc.). ), The gelling agent) is mixed and stirred in a powder state, the gelling agent is dispersed by saccharide, and then heated water is added to the temperature at which the gelling agent can be melted and stirred to melt the gelling agent, and then the fly is attracted. A method for producing a gel fly attractant, wherein the agent (0.5 to 3% by weight of the final product) is added and mixed and then solidified; 2) gel flies attractant (pH 3.8 or higher, sugar level 32 or higher) prepared by the above production method; And 3) a gel flies attractant and adhesive paper. However, it has been found that the fly (especially Drosophila) attractants or attractant compositions or fly capture devices disclosed in these documents have limitations in effectively combating flies (especially Drosophila).

In order to attract and eliminate Drosophilidae, also called fruit flies, fly flies, etc., especially Yellow Drosophila melongaster, which dominates indoors, it is necessary to design a attracting composition based on the ecological habits of Drosophila. From an ecological point of view, two important parts of the life history of fruit flies are divided into food sources and roosts. Temperature and humidity conditions (optimum: 25 ° C. and 70% RH) are similar to those of normal organisms, and the in-house environment provides a fairly good condition for their habitat. Drosophila adults have an instinct to find their own energy source and to find a place for spawning, and if they meet these conditions, their effects as fruit fly attractants can be maximized.

The mouth of Drosophila is composed of taste receptors composed of 31 hairs each, and their sensory groups respond to sugar components such as sucrose, salt, water, and caffeine, respectively, and have a high degree of reaction to sugar components and add sucrose. In light of the fact that the persuasive effect of fruit flies may be increased in some cases, the present inventors have conducted a thorough study, and then an aqueous solution of allerrin and / or phthalthrin, which are pyrethroid insecticides. M-α-glucoside, glucose (above monosaccharide), sucrose, maltose, turanose, palatinose, leucorose, trehalose (disaccharide), melezitose (trisaccharide), maltotriose , One or two or more sugar components selected from the group consisting of stachyose (above oligosaccharides) and maltitol (sugar alcohols), for example, 10 m per treatment space It was invented that the treatment at a concentration of M to 1M can construct a system that can effectively attract and kill fruit flies.

It is an object of the present invention to provide a composition for attracting and killing fruit flies and a fruit fly eliminator using the same, which can attract and kill fruit flies very efficiently without adversely affecting human health and environmental hygiene.

The present invention is m-α-glucoside, glucose (above monosaccharide) in 0.8-1.2% aqueous solution of a pyrethroid insecticide selected from the group consisting of allethrin, phthalthrin and combinations thereof , Sucrose, maltose, turanose, palatinose, leucorose, trehalose (disaccharide), melezitose (trisaccharide), maltotriose, starchiose (above oligosaccharides) and maltitol (sugar alcohols) It provides a composition for attracting and killing fruit flies, comprising one or two or more sugar components selected from the group consisting of 10mM to 1M.

The most important factor in the search for food during the behavioral behavior of fruit flies is the response to sugars. It also reacts to salts, fish foods, and caffeine, but the reaction is smaller than for sugars. The most sensitive sugar components in fruit flies include m-α-glucoside, glucose (dose monosaccharides), sucrose, maltose, turanose, palatinose, leucorose and trehalose (dose disaccharides). ), Melezitose (trisaccharide), maltotriose, starchiose (above oligosaccharides), maltitol (sugar alcohol) and the like. Such a sugar component is preferably an active ingredient for attracting fruit flies at a concentration of about 10 mM to 1 M per treatment space. An aqueous solution of a pyrethroid insecticide selected from the group consisting of allethrin, phthalthrin, and combinations thereof serves to kill fruit flies attracted by the sugar component. The systemic insecticide is preferably in the form of 0.8-1.2% aqueous solution. The concentration of the sugar component is preferably 3 to 5% by weight based on the total weight of the composition. The sugar component is more preferably m-α-glucoside, glucose, sucrose, maltitol, maltose, maltotriose or turanoose.

Drosophila attraction and killing compositions of the present invention preferably further comprises salt, caffeine or a mixture of two or more thereof (0.01 to 0.05% by weight based on the total weight of the composition), which is added caffeine and / or salt This is because the fruit fly attraction effect is maximized. Since sugar receptors and caffeine and / or salt receptors are present at different sites and thus exhibit no synergistic effect, they can attract fruit flies more efficiently than simply stimulating sugar receptors alone.

Drosophila attraction and killing compositions of the present invention may further comprise starch starch, potato starch, corn starch, flour or a mixture of two or more thereof. For example, corn starch preferably contains 4 to 6% by weight, more preferably 5 to 5.5% by weight, and in the case of wheat flour, preferably 0.5 to 2% by weight, more preferably 0.5 to 1% by weight. Contains% At concentrations lower than these numerical ranges, the effect is weak, and at concentrations higher than these numerical ranges, adverse effects such as agglomeration or forming an oil film to suppress volatilization of the active ingredient can be produced.

Drosophila attraction and killing composition of the present invention is a fatty acid compound selected from the group consisting of oleic acid, lauryl acid, stearyl acid, myristyl acid, acetic acid, lactic acid and propionic acid (0.1 to 0.5% by weight based on the total weight of the composition ) May be additionally included. In particular, when pyrophytic acid having a high volatility, a strong irritation, and a salt can have a bactericidal power, the effect is maximized when 0.1 to 0.3% by weight, which is less than 0.1% by weight, and 0.3 weight If it exceeds the amount is because the irritating odor can give a great discomfort to the user.

 Drosophila attractant and killing composition of the present invention is one or two or more dry yeasts selected from the group consisting of baker's yeast, sake yeast, beer yeast and alcohol yeast (0.05 to 2.0% by weight, based on the total weight of the composition, more Preferably from 1.3 to 1.6% by weight). These alone have limitations on the fruit fly attraction, but can further enhance the fruit fly attraction when used with the sugar component, or the sugar component and caffeine / saline.

Drosophila attractant and killing composition of the present invention can be imparted by a fatty acid compound such as pyropyronic acid, but because most of the composition is composed of food, etc. may be vulnerable to mold, bacteria, etc., used in food, etc. It may further comprise conventional preservatives.

In addition, the fruit fly attraction and killing composition of the present invention may be in the form of a gel using agar and other gelling agents, or may be in a liquid state.
