Detailed description of the invention
Hereinafter, for embodiments of the present invention, it is described in detail further., it is described in detail for the Scolopendra as proper object herein, but the situation that not will be applied onto other insects such as locust, Citrullus vulgaris worm, Prospirolboli joannsi, common house centipede dragonfly, Formica fusca is got rid of.
The insect of the present invention is (following with poison bait agent, referred to as " poison bait agent ") it is characterised by, containing insecticidal constituent and lure composition, alternatively absorb the moisture in air over time, make to lure composition deliquescence, thus formed surface by become aqueous described in lure composition to cover state.The surface of poison bait agent is covered by fraction, becomes the state of moistening, and therefore, insect easily eats.Wherein, if the predatism insects such as Scolopendra its mouthful touching containing moisture lure composition (fraction), then taken as food, taked the action eaten, therefore, to Scolopendra particularly suitable, it is possible to effectively prevent and treat.
It should be noted that " deliquescence " refers to, the moisture in material absorbing air is thus becoming the phenomenon of aqueous solution, and in the present invention, the composition of luring in poison bait agent has the character of hygroscopy.
nullAs the insecticidal constituent used in the present invention,As long as insect is had insecticidal effect,Then it is not particularly limited,Such as can enumerate: Folithion、Diazinon、Marathon、Pyridaphethione、BAY-NTN 8629、Phoxim、The organophosphor based compounds such as chlopyrifos、Sevin、Arprocarb、Methomyl、The carbamates such as thiodicarb (カ mono-バ メ イ ト) based compound、Allethrin、Resmethrin、PH、Tetramethrin、Permethrin、Phenothrin、Match is gone out peaceful、Cyphenothrin、Prallethrin、Prallethrin、Transfluthrin、Metofluthrin、The pyrethroid based compounds such as general fluorine peaceful (profluthrin)、Two azole compounds such as metoxadiazone (metoxadiazone)、The Phenylpyrazole based compounds such as fipronil、Boric acid、Borax、Hydramethylnon、MTI-446、Imiprothrin etc..These insecticidal constituents may be used alone, can also be 2 or more kinds in combination.
Lure the deliquescence of composition to make poison bait agent surface be surrounded by fraction as long as the use level of insecticidal constituent does not interfere with utilization, then can consider that titer (Japanese: power) suitably sets.Specifically, in poison bait agent, it is preferable that containing more than 0.1 weight %, more preferably more than 0.5 weight %.Additionally, it is preferred that the upper limit is less than 30 weight %.
The composition of luring used in the present invention is the composition that insect is liked, and can select have the aforesaid moisture alternatively absorbed over time in air to carry out the composition of the character of deliquescence.For example, it is possible to enumerate: aminoacid etc. such as the saccharides such as glucose, fructose, galactose, maltose, sucrose, dextrin, berry sugar, brown sugar, alanine, glycine, valine, aspartic acid, glutamic acid.These lure composition may be used alone, can also be 2 or more kinds in combination.
As long as these lure composition containing being arranged within doors in poison bait agent, absorb the moisture in air behind desired place outside room and become aqueous and be exuded to the amount on surface of poison bait agent, and suitably set according to the shape of poison bait agent, size etc..
In the present invention, in order to make the composition of luring of deliquescence be exuded to the surface of poison bait agent, relevant with the beeline from the surface of poison bait agent to center of gravity.It should be noted that the center of gravity of poison bait agent is not only the weight center in the axle center being positioned at poison bait agent, it is also possible to be the geometric center on axle center.
In the present invention, it is preferable that form poison bait agent in the mode that the beeline from the surface of poison bait agent to center of gravity is below 10mm.Being below 10mm by making the beeline from the surface of poison bait agent to center of gravity, thus not only close with the surface portion in poison bait agent composition of luring, internal lures the moisture in composition also absorbed air, liquefies, thus being easily exuded to the surface of poison bait agent.
It should be noted that the beeline from the surface of poison bait agent to center of gravity is more short, composition is lured more easily to be exuded to the surface of poison bait agent, therefore, for the poison bait agent that particle diameter is little, it is possible to reduce the content luring composition.Therefore, it is possible to according to the beeline from the surface of poison bait agent to center of gravity, adjust the content luring composition in poison bait agent.
Specifically, when the beeline from the surface of poison bait agent to center of gravity is less than 2mm, using the weight before deliquescence as benchmark, containing luring more than composition 40 weight % in preferred poison bait agent, it is more than 2mm and during less than 2.5mm in beeline, it is preferable that contain and lure more than composition 60 weight %, it is more than 2.5mm and during less than 6mm in beeline, preferably comprise and lure more than composition 70 weight %, when beeline is more than 6mm, it is preferable that containing luring more than composition 80 weight %.It addition, for the effect giving full play to the present invention, it is preferable that making beeline is below 10mm.
As the form of poison bait agent, as long as solid shape, it is not particularly limited, it is possible to suitably set.Such as can enumerate: graininess, powdery, cylindric, discoid, section shape, bulk, paste etc..As shown in Fig. 5 (a), when poison bait agent 1A is discoid preparation, using from the surface of the direction of principal axis X of poison bait agent to the length of center of gravity as beeline m, as shown in Fig. 5 (b), when the columned preparation that poison bait agent 1B is major axis, using from the surface in the direction of the direction of principal axis Y orthogonal of poison bait agent to the length (radius length of the facet relative to direction of principal axis Y) of center of gravity as beeline n, suitably adjust the use level luring composition.
As it has been described above, adjust the content luring composition according to the beeline from the surface of poison bait agent to center of gravity, thus luring composition can fully be become aqueous by deliquescent effect, the surface fraction of poison bait agent is covered by the degree being considered as food with insect.When the content luring composition is insufficient, it is impossible to enough fraction fully cover poison bait agent surface, not enough so that insect is considered as food, therefore not preferred.
In the poison bait agent of the present invention, lure the moisture in ingredient draws air and deliquescence, therefore, it is possible to the surface of poison bait agent is kept into moisture state by the change according to the humidity etc. of natural environment.It addition, as it has been described above, according to the beeline from the surface of poison bait agent to center of gravity containing more than scheduled volume luring composition, even if thus under the low-humidity environment such as night, winter, it is also possible to cover poison bait agent surface by fraction.
It should be noted that when object insect is Scolopendra, Scolopendra has nocturnal habit, it is thus preferred to the use level luring composition is adjusted to deliquescence state and can keep for about 1 evening (such as, 12~16 hours).
In the poison bait agent of the present invention, except described hygroscopy lures composition, insecticidal constituent, it is possible to coordinate known various composition as required.As other compositions, for instance can enumerate: excipient, antioxidant, preservative, anti-eat agent, solvent etc. by mistake.
