Specific embodiment
Hereinafter, being directed to embodiments of the present invention, it is further described in detail.Herein, using the Wu as proper object The case where being described in detail for centipede, but not will be applied onto other pests such as locust, watermelon worm, julid, common house centipede dragonfly, ant row It removes.
Pest of the invention is characterized in that with poison bait agent (hreinafter referred to as " poison bait agent "), containing insecticidal constituent and is drawn Ingredient is lured, the moisture in atmosphere with time change is absorbed, makes that ingredient is lured to deliquesce, so that forming surface is had become liquid The state for luring ingredient to cover.The surface of poison bait agent is covered by liquid material, becomes the state of wetting, and therefore, pest is held It is easily edible.Wherein, as long as its mouthful of touching of the predatism such as centipede pest lures ingredient (liquid material) containing moisture, taken as Food takes edible action, therefore, particularly suitable to centipede, can effectively prevent.
It should be noted that the phenomenon that " deliquescence " refers to, the moisture in material absorbing atmosphere is to become aqueous solution, at this In invention, property of the ingredient with hygroscopy is lured in poison bait agent.
Insecticidal constituent used in the present invention is then not particularly limited, example as long as having insecticidal effect to pest It can such as enumerate: Folithion, diazinon, marathon, pyridaphethione, Toyodan, phoxim, chlopyrifos organic phosphorus chemical combination The carbamates such as object, sevin, arprocarb, Methomyl, thiodicarb (mono- バ メ イ ト of カ) based compound, allethrin, benzyl furan Pyrethroids, proventhrin, tetramethrin, Permethrin, phenothrin, match go out peaceful, cyphenothrin, Prallethrin, Prallethrin, phenyl tetrafluoride The pyrethroids based compounds, metoxadiazone such as pyrethroids, metofluthrin, general fluorine peaceful (profluthrin) (metoxadiazone) Phenylpyrazoles based compound, boric acid, borax, hydramethylnon, the furan such as oxadiazoles based compound, fipronil such as Worm amine, Imiprothrin etc..These insecticidal constituents may be used alone, can also be 2 or more kinds in combination.
The deliquescence of ingredient is lured to surround poison bait agent surface by liquid material as long as the use level of insecticidal constituent does not interfere to utilize, Then it is contemplated that titer (Japanese: power value) and suitably set.Specifically, in poison bait agent, preferably comprise 0.1 weight % with On, more preferable 0.5 weight % or more.Additionally, it is preferred that the upper limit is less than 30 weight %.
It is the ingredient that pest is liked that ingredient is lured used in the present invention, and can select to have above-mentioned with the time Absorb the moisture in atmosphere alternatively with the ingredient of the property deliquesced.For example, can enumerate: glucose, fructose, gala The carbohydrates such as sugar, maltose, sucrose, dextrin, berry sugar, brown sugar, alanine, glycine, valine, aspartic acid, glutamic acid etc. Amino acid etc..These lure ingredient may be used alone, can also be 2 or more kinds in combination.
It is absorbed in air behind the desired place that poison bait agent is arranged within doors, outside room as long as these lure ingredient to contain Moisture and become liquid and be exuded to the amount on the surface of poison bait agent, and it is appropriate according to the shape of poison bait agent, size etc. Setting.
In the present invention, in order to which make to have deliquesced lures ingredient to be exuded to the surface of poison bait agent, and from the surface of poison bait agent The shortest distance to center of gravity is related.It should be noted that the center of gravity of poison bait agent is not only in the weight in the axle center of poison bait agent The heart is also possible to the geometric center on axle center.
It is preferably to form poison bait in a manner of 10mm is below by the shortest distance from the surface of poison bait agent to center of gravity in the present invention Agent.By make shortest distance 10mm from the surface of poison bait agent to center of gravity hereinafter, to not only with the surface element in poison bait agent Point close lures ingredient, and internal lures ingredient also to adsorb the moisture in air, liquefies, to be easy to be exuded to poison bait The surface of agent.
It should be noted that the shortest distance from the surface of poison bait agent to center of gravity is shorter, lure ingredient is easier to be exuded to The surface of poison bait agent, therefore, the poison bait agent small for partial size can reduce the content for luring ingredient.It therefore, can be according to from poison The surface of bait formulation adjusts the content for luring ingredient in poison bait agent to the shortest distance of center of gravity.
Specifically, when the shortest distance from the surface of poison bait agent to center of gravity is less than 2mm, using the weight before deliquescing as Benchmark in the shortest distance is 2mm or more and when less than 2.5mm containing luring 40 weight % of ingredient or more preferably in poison bait agent, It preferably comprises and lures 60 weight % of ingredient or more, in the shortest distance be 2.5mm or more and when less than 6mm, preferably comprise and lure into Divide 70 weight % or more, when the shortest distance is 6mm or more, preferably comprises and lure 80 weight % of ingredient or more.In addition, in order to fill Effect of the invention is waved in distribution, preferably makes shortest distance 10mm or less.
