Description

害虫用毒餌剤Pest poison bait
　本発明は、害虫用毒餌剤に関し、より詳しくは、特にムカデの防除に適した害虫用毒餌剤に関する。 The present invention relates to a pest poison bait, and more particularly to a pest poison bait particularly suitable for controlling centipedes.
　従来、ムカデ、ゴキブリ、アリ等の害虫の防除のために、害虫の嗜好性が高くかつ殺虫成分を含有する毒餌剤を、害虫の発生場所に設置し、害虫に喫食させて防除する方法がある。 Conventionally, in order to control pests such as centipedes, cockroaches, ants, etc., there is a method in which a pest that has a high palatability of pests and contains an insecticidal component is installed at the place where the pests are generated and eaten by the pests. .
　例えばムカデは、草むら、石垣の間、土壌中等に生息し、小型の昆虫、クモ、ミミズ等を食物とし、時には食物を求めて家屋内に侵入したり、家具や靴の中に潜んで、その際に人を咬んでアレルギー反応を起こすという被害をもたらすことから、防除の対象とされている。
　ムカデを防除するに際して毒餌剤を用いる場合、ムカデを誘引して毒餌剤を十分に喫食させることが重要となってくる。この課題を解決するために、例えば、下記特許文献１には、イカの乾燥粉末、魚白子の乾燥粉末、カニ殻の粉末のうち、少なくとも１種を含有したムカデ用誘引剤、およびこの誘引剤と殺虫成分を含有したムカデ用毒餌剤が開示されている。 For example, centipedes inhabit grass, stone walls, soil, etc., and eat small insects, spiders, earthworms, etc. as food, sometimes enter the house for food, lurk in furniture and shoes, Because it causes the damage of biting people and causing allergic reactions, it is targeted for control.
When a poison bait is used in controlling a centipede, it is important to attract the centipede and eat the poison bait sufficiently. In order to solve this problem, for example, in Patent Document 1 below, an attractant for centipede containing at least one of dry powder of squid, dry powder of fish white, and powder of crab shell, and the attractant And a poison bait for centipedes containing an insecticidal component.

　しかしながら、毒餌剤に誘引剤を添加しても、毒餌剤の硬さや柔らかさ、大きさ、表面状態等によって害虫の喫食が影響を受けることがある。
　特に、ムカデのような捕食性の害虫は小型の昆虫など動くものを捕食していることから、誘引剤を含む毒餌剤を単に置いただけではこれを食物とは認識せず、十分に喫食させることは難しい。 However, even if an attractant is added to the poison bait, the eating of the pests may be affected by the hardness, softness, size, surface condition, etc. of the poison bait.
In particular, predatory pests such as centipedes prey on moving things such as small insects, so if you simply place a poison bait containing an attractant, it will not be recognized as food and you will eat it sufficiently Is difficult.
　そこで本発明の目的は、特にムカデの防除に適した毒餌剤であって、高い喫食性を有する害虫用毒餌剤を提供することにある。 Therefore, an object of the present invention is to provide a poisonous bait that is particularly suitable for controlling centipedes and has a high eating property.
　本発明者らは鋭意研究を重ねた結果、ムカデのような捕食性害虫に毒餌剤を十分に喫食させるには、該毒餌剤に含まれる誘引成分を潮解させ、潮解した誘引成分で毒餌剤の表面を覆うことにより前記課題を解決できることを見出し、本発明を完成することができた。 As a result of intensive research, the present inventors have devolatilized predatory pests such as centipedes to sufficiently eat the poison bait, and deliquescent the attractant component contained in the poison bait, It was found that the problem can be solved by covering the surface, and the present invention has been completed.
　すなわち本発明は、以下の（１）～（２）によって達成されるものである。
（１）ムカデの防除に適した毒餌剤であって、殺虫成分と誘引成分とを含有し、経時的に大気中の水分を吸収して誘引成分が潮解し、液状となった前記誘引成分で表面が覆われた状態となる固形状の害虫用毒餌剤。
（２）毒餌剤の表面から重心までの最短距離が１０ｍｍ以下である前記（１）に記載の害虫用毒餌剤。 That is, the present invention is achieved by the following (1) to (2).
(1) A poisonous bait suitable for controlling centipedes, which contains an insecticidal component and an attracting component, absorbs moisture in the atmosphere over time, and the attracting component is deliquesced and becomes a liquid. A solid pest poison that is covered in a solid state.
(2) The pest poison bait according to (1), wherein the shortest distance from the surface of the poison bait to the center of gravity is 10 mm or less.
　本発明の害虫用毒餌剤は、そこに含まれる誘引成分を潮解させ、液状となった誘引成分で毒餌剤の表面を覆うようにしたので、毒餌剤に接触した害虫が餌と認識しやすくなり、喫食性が高まるため、防除効果を高めることができる。特にムカデに対する高い喫食性を有し、殺虫成分を十分に喫食させることができるので、ムカデの防除に極めて有効である。 The pest poison bait according to the present invention has been deliquescent of the attracting component contained therein, and the liquid attracting component covers the surface of the poison bait so that the pest that has come into contact with the poison bait can be easily recognized as bait. Since the eating property is enhanced, the control effect can be enhanced. In particular, since it has a high eating property with respect to centipedes and can sufficiently eat insecticidal components, it is extremely effective for controlling centipedes.

　殺虫成分の配合量は、誘引成分の潮解により毒餌剤表面が液状物により包囲されることが妨げられない限り、力価を考慮して適宜設定することができる。具体的には、毒餌剤中、０．１重量％以上含有するのが好ましく、０．５重量％以上がより好ましい。また上限は３０重量％未満が好ましい。 The compounding amount of the insecticidal component can be appropriately set in consideration of the titer as long as the deliquescent of the attracting component does not prevent the poison bait surface from being surrounded by the liquid material. Specifically, the content is preferably 0.1% by weight or more, more preferably 0.5% by weight or more in the poison bait. The upper limit is preferably less than 30% by weight.
　本発明で使用する誘引成分は、害虫が嗜好する成分であり、かつ前記したように経時的に大気中の水分を吸収して潮解する性質を有するものを選択することができる。例えば、グルコース、果糖、ガラクトース、麦芽糖、ショ糖、デキストリン、グラニュー糖、黒糖等の糖類、アラニン、グリシン、バリン、アスパラギン酸、グルタミン酸等のアミノ酸等が挙げられる。これらの誘引成分は、１種を単独で用いてもよく、２種以上を混合して用いてもよい。 The attracting component used in the present invention can be selected from components that are preferred by pests and that have the property of absorbing and deliquescent moisture in the atmosphere over time as described above. Examples thereof include sugars such as glucose, fructose, galactose, maltose, sucrose, dextrin, granulated sugar and brown sugar, and amino acids such as alanine, glycine, valine, aspartic acid and glutamic acid. These attracting components may be used alone or in combination of two or more.
　これらの誘引成分は、毒餌剤が屋内や屋外の所望の場所に設置された後に空気中の水分を吸って液状となり、毒餌剤の表面に滲み出てくるような量が含有されていればよく、毒餌剤の形状、大きさ等により適宜設定すればよい。 These attracting ingredients only need to contain such an amount that the poison bait becomes liquid after absorbing moisture in the air after it is installed indoors or outdoors in a desired location, and oozes out on the surface of the poison bait. What is necessary is just to set suitably according to the shape of a poison bait, a magnitude | size, etc.
　本発明において、潮解した誘引成分が毒餌剤の表面に滲み出るようにするためには、毒餌剤の表面から重心までの最短距離が関係している。なお、毒餌剤の重心とは、毒餌剤の軸心上に位置する重量中心だけでなく、軸心上の幾何学的中心であってもよい。
　本発明において、毒餌剤の表面から重心までの最短距離が１０ｍｍ以下となるように毒餌剤を成形することが好ましい。毒餌剤の表面から重心までの最短距離を１０ｍｍ以下とすることで、毒餌剤中の表面部分に近い誘引成分だけでなく、内部の誘引成分も空気中の水分を吸着して液状化し、毒餌剤の表面に滲み出やすくなる。 In the present invention, the shortest distance from the surface of the poison bait to the center of gravity is involved in order for the deliquescent attractant to ooze out on the surface of the poison bait. Note that the center of gravity of the poison bait may be not only the center of weight located on the axis of the poison bait but also the geometric center on the axis.
In the present invention, the poison bait is preferably molded so that the shortest distance from the surface of the poison bait to the center of gravity is 10 mm or less. By making the shortest distance from the surface of the poison bait to the center of gravity 10 mm or less, not only the attracting component close to the surface part in the poison bait but also the internal attracting component adsorbs moisture in the air and liquefies, It becomes easy to ooze out on the surface.
　なお、毒餌剤の表面から重心までの最短距離が短くなればなるほど誘引成分が毒餌剤の表面に滲み出やすくなるため、粒径の小さい毒餌剤では誘引成分の含有量を少なくすることができる。よって、毒餌剤の表面から重心までの最短距離に応じて毒餌剤中の誘引成分の含有量を調整することができる。
　具体的には、毒餌剤の表面から重心までの最短距離が２ｍｍ未満の場合は、潮解する前の重量を基準として、毒餌剤中、誘引成分を４０重量％以上含有させるのが好ましく、最短距離が２ｍｍ以上２．５ｍｍ未満の場合は誘引成分を６０重量％以上含有させるのが好ましく、最短距離が２．５ｍｍ以上６ｍｍ未満の場合は誘引成分を７０重量％以上含有させるのが好ましく、最短距離が６ｍｍ以上の場合は誘引成分を８０重量％以上含有させるのが好ましい。また本発明の効果を十分発揮させるためには最短距離を１０ｍｍ以下とするのが好ましい。 In addition, since the attracting component oozes more easily on the surface of the poison bait as the shortest distance from the surface of the poison bait to the center of gravity becomes shorter, the content of the attracting component can be reduced in the poison bait having a small particle size. Therefore, the content of the attracting component in the poison bait can be adjusted according to the shortest distance from the surface of the poison bait to the center of gravity.
Specifically, when the shortest distance from the surface of the poison bait to the center of gravity is less than 2 mm, it is preferable to contain at least 40% by weight of the attracting component in the bait based on the weight before deliquescent, and the shortest distance Is preferably 2% or more and less than 2.5mm, it is preferable to contain at least 60% by weight of the attracting component. When the thickness is 6 mm or more, it is preferable to contain 80% by weight or more of an attracting component. In order to sufficiently exhibit the effects of the present invention, the shortest distance is preferably 10 mm or less.
　毒餌剤の形態としては、固形状であれば特に限定されず、適宜設定すればよい。例えば、顆粒状、粉状、円柱状、円盤状、ブロック状、塊状、ペースト状等が挙げられる。図５（ａ）に示すように、毒餌剤１Ａが円盤状の製剤のときは、毒餌剤の軸方向Ｘの表面から重心までの長さを最短距離ｍとし、図５（ｂ）に示すように、毒餌剤１Ｂが長軸の円柱状の製剤のときは、毒餌剤の軸方向Ｙとは直交する方向の表面から重心までの長さ（軸方向Ｙに対する切断面の半径長さ）を最短距離ｎとして誘引成分の配合量を適宜調整すればよい。 The form of the poison bait is not particularly limited as long as it is solid, and may be set as appropriate. For example, granule shape, powder shape, columnar shape, disk shape, block shape, lump shape, paste shape and the like can be mentioned. As shown in FIG. 5 (a), when the poison bait 1A is a disc-shaped preparation, the length from the surface in the axial direction X to the center of gravity of the poison bait is the shortest distance m, and as shown in FIG. 5 (b). In addition, when the poison bait 1B is a long-axis columnar preparation, the length from the surface in the direction perpendicular to the axial direction Y of the poison bait to the center of gravity (the radial length of the cut surface with respect to the axial direction Y) is the shortest. What is necessary is just to adjust the compounding quantity of an attracting component suitably as the distance n.
　上記のように毒餌剤の表面から重心までの最短距離に応じて誘引成分の含有量を調整することにより、潮解作用により誘引成分が十分に液状となり、害虫が食べものであると認識する程度に毒餌剤の表面を液状物で覆うことができる。誘引成分の含有量が十分でない場合は、毒餌剤表面を液状物で十分に覆うことができず、害虫が食物であると認識するには不十分となるので好ましくない。 By adjusting the content of the attracting component according to the shortest distance from the surface to the center of gravity of the poison bait as described above, the bait is sufficiently liquefied by deliquescent action so that the pest is recognized as a food. The surface of the agent can be covered with a liquid material. If the content of the attracting component is not sufficient, the surface of the poison bait cannot be sufficiently covered with the liquid material, and it is not preferable for the pest to be recognized as food.
　本発明の毒餌剤は、誘引成分が空気中の水分を吸収して潮解するため、自然環境の湿度等の変化に応じて毒餌剤の表面を湿潤状態に保つことができる。また、上記のように毒餌剤の表面から重心までの最短距離に応じて所定量以上の誘引成分を含有させておくことで、夜間や冬季などの低湿度環境においても毒餌剤表面を液状物で覆うことができる。 In the poison bait of the present invention, the attracting component absorbs moisture in the air and deliquesces, so that the surface of the poison bait can be kept moist according to changes in the natural environment such as humidity. In addition, as described above, by containing a predetermined amount or more of an attracting component according to the shortest distance from the surface of the poison bait to the center of gravity, the surface of the poison bait is liquid even in a low humidity environment such as at night or in winter. Can be covered.
　なお、対象害虫がムカデの場合、ムカデは夜行性であるため、潮解状態を一晩（例えば、１２～１６時間）程度保つことができるように誘引成分の配合量を調整することが好ましい。 In addition, when the target pest is a centipede, the centipede is nocturnal, and therefore it is preferable to adjust the blending amount of the attraction component so that the deliquescent state can be maintained overnight (for example, 12 to 16 hours).
　本発明の毒餌剤には、前記した潮解性の誘引成分、殺虫成分以外に、必要に応じて、公知の各種成分を配合することができる。その他の成分としては、例えば、賦形剤、酸化防止剤、保存剤、誤食防止剤、溶剤等が挙げられる。 In addition to the deliquescent attracting and insecticidal components described above, various known components can be blended with the poison bait of the present invention as required. Examples of other components include excipients, antioxidants, preservatives, anticorrosive agents, solvents, and the like.

　酸化防止剤としては、例えば、エリソルビン酸、エリソルビン酸ナトリウム、ジブチルヒドロキシトルエン、ｄｌ－α－トコフェロール、ブチルヒドロキシアニソール、没食子酸プロピル等が挙げられる。 Examples of the antioxidant include erythorbic acid, sodium erythorbate, dibutylhydroxytoluene, dl-α-tocopherol, butylhydroxyanisole, propyl gallate and the like.
　保存剤としては、例えば、安息香酸、安息香酸ナトリウム、安息香酸ベンジル、サリチル酸ベンジル、サリチル酸、ソルビン酸、ソルビン酸カリウム、デヒドロ酢酸、デヒドロ酢酸ナトリウム、パラオキシ安息香酸エステル、プロピオン酸カルシウム、プロピオン酸ナトリウム、塩化セチルピリジニウム等が挙げられる。 Examples of preservatives include benzoic acid, sodium benzoate, benzyl benzoate, benzyl salicylate, salicylic acid, sorbic acid, potassium sorbate, dehydroacetic acid, sodium dehydroacetate, parahydroxybenzoic acid ester, calcium propionate, sodium propionate, And cetylpyridinium chloride.
　誤食防止剤としては、例えば、安息香酸デナトニウム、トウガラシ末等が挙げられる。 Examples of the anti-fouling agent include denatonium benzoate and pepper powder.
　溶剤としては、水、イソプロピルアルコール、エタノール、グリセリン等のアルコール類、プロピレングリコール、エチレングリコール等のグリコール類、パラフィン類等が挙げられる。 Examples of the solvent include water, alcohols such as isopropyl alcohol, ethanol and glycerin, glycols such as propylene glycol and ethylene glycol, and paraffins.
　この他にも、必要に応じて、香料、着色剤、ｐＨ調整剤等を用いることができる。 In addition to this, a fragrance, a colorant, a pH adjuster, and the like can be used as necessary.
　さらに本発明においては、発明の効果を損なわない範囲において、潮解性の性質を持たないその他の誘引成分、例えば、さなぎ粉、コーンスターチ、ハチノコ、ビーフ、タマゴ、オキアミ、エビ、チーズ、畜肉、魚肉、澱粉、小麦粉、フスマ、豆、米ぬか、種子、綿実、やし油、オリーブ油、肉油、魚油、ゴマ油等を用いることもできる。 Furthermore, in the present invention, other attracting ingredients that do not have deliquescent properties, for example, pupa flour, cornstarch, wasp, beef, egg, krill, shrimp, cheese, livestock meat, fish meat, Starch, wheat flour, bran, beans, rice bran, seeds, cottonseed, palm oil, olive oil, meat oil, fish oil, sesame oil and the like can also be used.
　本発明の毒餌剤の調製方法としては、公知の手法が採用され、例えば、原料成分を混合、打錠する方法、造粒方法等が挙げられる。 As a method for preparing the poisonous bait of the present invention, a known method is employed, and examples thereof include a method of mixing and tableting raw material components, and a granulation method.
　本発明の毒餌剤は、その表面が、非使用時は乾燥状態であり、使用時に潮解状態になるように包装・保存することが好ましい。非使用時を乾燥状態にすることにより、流通時または保管時のハンドリング性を向上させることができる。非使用時に本発明の毒餌剤を乾燥状態に保つためには、例えば、毒餌剤を使用するまで気密性を有する容器・袋等の内部にシリカゲル等の乾燥剤と共に保存するなどして、湿度が極めて低い状態を保つことが好ましい。 The poison bait of the present invention is preferably packaged and stored so that its surface is in a dry state when not in use and is in a deliquescent state when in use. By making the non-use time dry, the handling property at the time of distribution or storage can be improved. In order to keep the poison bait of the present invention in a dry state when not in use, for example, it is stored in a container or bag having airtightness with a desiccant such as silica gel until the poison bait is used. It is preferable to keep a very low state.
　本発明において、使用時に誘引成分が潮解し、毒餌剤の表面が液状物で覆われた潮解状態は目視で確認することができる。また、パルプ製のワイピングクロス（例えば日本製紙クラシエ株式会社製「キムワイプＳ－２００」）を荷重をかけることなく約５秒間接触させた際に、液状となった誘引成分がパルプ製ワイピングクロス表面に付着する、という事象によっても確認することができる。 In the present invention, it is possible to visually confirm the deliquescent state in which the attracting component is deliquescent and the surface of the poisonous bait is covered with a liquid material during use. In addition, when a wiping cloth made of pulp (for example, “Kimwipe S-200” manufactured by Nippon Paper Industries Co., Ltd.) is brought into contact for about 5 seconds without applying a load, the attracting component that has become a liquid forms on the surface of the wiping cloth made of pulp. It can also be confirmed by the phenomenon of adhesion.
　以下、本発明を以下の試験例によりさらに説明するが、本発明は下記例に制限されるものではない。 Hereinafter, the present invention will be further described by the following test examples, but the present invention is not limited to the following examples.
＜毒餌剤の経時試験＞
　表１に記載の毒餌剤基剤１００重量部に対し、水４．５重量部、エタノール３重量部を加えて混練し、図５（ｂ）に示すような、直径約５ｍｍ、長さ約１０ｍｍの円柱状に成形して毒餌剤を得た（検体１、２）。続いて、得られた各毒餌剤約１ｇを、２０～２３℃、湿度１００％の条件下で７２時間保存した。
　成形直後の毒餌剤の状態を図１（ａ）及び図１（ｂ）に、保存後の毒餌剤の状態を図２（ａ）及び図２（ｂ）に示す。図１（ａ）及び図２（ａ）は検体１の毒餌剤を示し、図１（ｂ）及び図２（ｂ）は検体２の毒餌剤を示す。 <Aging test of poison bait>
4.5 parts by weight of water and 3 parts by weight of ethanol are added to 100 parts by weight of the bait base shown in Table 1 and kneaded. As shown in FIG. 5 (b), the diameter is about 5 mm and the length is about 10 mm. A poisonous bait was obtained by molding into a cylindrical shape (Samples 1 and 2). Subsequently, about 1 g of each obtained poisonous bait was stored for 72 hours under the conditions of 20 to 23 ° C. and humidity of 100%.
The state of the poison bait immediately after molding is shown in FIGS. 1 (a) and 1 (b), and the state of the poison bait after storage is shown in FIGS. 2 (a) and 2 (b). 1 (a) and 2 (a) show the poison bait of specimen 1, and FIGS. 1 (b) and 2 (b) show the poison bait of specimen 2. FIG.
Figure JPOXMLDOC01-appb-T000001
Figure JPOXMLDOC01-appb-T000001
　図２（ａ）及び図２（ｂ）の結果から、検体１の毒餌剤は、保存中に経時的に大気中の水分を吸収して誘引成分が潮解し、液状となった前記誘引成分で表面が覆われた状態となることが分かった。これに対し、検体２の毒餌剤は、誘引成分が潮解せず、保存前後で形状の変化はほとんど見られなかった。 From the results of FIGS. 2 (a) and 2 (b), the poison bait of specimen 1 absorbs moisture in the atmosphere over time during storage and the attracting component is deliquescent, and the attracting component that has become liquid It was found that the surface was covered. On the other hand, in the poison bait of the specimen 2, the attracting component did not deliquesce, and almost no change in shape was observed before and after storage.
＜毒餌剤の吸湿確認＞
　検体１および２の毒餌剤約１ｇについて、２０～２３℃、湿度１００％の条件下で７２時間保存した後の重量増加倍率を以下の式により求めた。試験は各検体につき２回ずつ行い、その平均を求めた。結果を表２に示す。
　吸湿による重量増加倍率＝保存後の毒餌剤の重量／保存前の毒餌剤の重量 <Check moisture absorption of poison bait>
About 1 g of the poisonous bait of specimens 1 and 2, the weight increase rate after storage for 72 hours under the conditions of 20 to 23 ° C. and 100% humidity was determined by the following formula. The test was performed twice for each specimen, and the average was obtained. The results are shown in Table 2.
Weight increase ratio due to moisture absorption = Poisonous bait weight after storage / Poisonous bait weight before storage
Figure JPOXMLDOC01-appb-T000002
Figure JPOXMLDOC01-appb-T000002
　表２の結果から、検体１および検体２の毒餌剤の保存後の吸湿による重量増加倍率は同程度であり大きな差はないことがわかる。図２（ａ）及び図２（ｂ）に示したように、検体１の毒餌剤は、保存後において表面が液状物で覆われた状態になるのに対し、検体２の毒餌剤はほとんど変化がないことから、検体１では経時的に大気中の水分を吸収して誘引成分が潮解し、毒餌剤の表面に滲み出てくるのに対し、検体２は、毒餌剤全体で水分を吸収し、水分を毒餌剤内に取り込んでいるものと考えられる。 From the results in Table 2, it can be seen that the weight increase ratios due to moisture absorption after storage of the poison baits of Sample 1 and Sample 2 are similar, and there is no significant difference. As shown in FIGS. 2 (a) and 2 (b), the poison bait of the specimen 1 is in a state in which the surface is covered with a liquid after storage, whereas the poison bait of the specimen 2 is almost changed. In contrast, specimen 1 absorbs moisture in the atmosphere over time and the attracting component deliquesces and oozes out on the surface of the poison bait, whereas specimen 2 absorbs moisture throughout the poison bait. It is thought that moisture is taken into the poison bait.
＜毒餌剤の表面状態確認試験＞
　上記保存後の検体１および２の毒餌剤に対し、１ｃｍ幅の短冊状に切断したワイピングクロス（日本製紙クラシエ株式会社製「キムワイプＳ－２００」）を、荷重をかけずに毒餌剤上に静置し、５秒間放置した。その後ワイピングクロスを回収し、ワイピングクロスの表面状態を目視で確認した。検体１の結果を図３（ａ）及び図３（ｂ）に示し、検体２の結果を図４（ａ）及び図４（ｂ）に示す。 <Poison bait surface condition confirmation test>
A wiping cloth (“Kimwipe S-200” manufactured by Nippon Paper Industries Co., Ltd.) cut into a 1 cm-wide strip is placed on the poisonous bait without applying a load to the poisonous bait of specimens 1 and 2 after storage. And left for 5 seconds. Thereafter, the wiping cloth was collected, and the surface state of the wiping cloth was visually confirmed. The results of the sample 1 are shown in FIGS. 3 (a) and 3 (b), and the results of the sample 2 are shown in FIGS. 4 (a) and 4 (b).
　保存後の検体１の毒餌剤は、図３（ａ）に示したように、ワイピングクロスと接触直後に、毒餌剤の表面を覆っている液状となった誘引成分がワイピングクロスに吸収され、図３（ｂ）に示したように、５秒後に回収したワイピングクロスの表面には液状となった誘引成分とともに毒餌剤の一部も付着していた。一方、検体２の毒餌剤は、図４（ａ）および図４（ｂ）に示したように、ワイピングクロス表面に何も付着しなかった。
　このことからも、検体１の毒餌剤は、経時的にその表面状態が変化することがわかる。 As shown in FIG. 3A, the poison bait of the specimen 1 after storage is absorbed by the wiping cloth immediately after contact with the wiping cloth, and the liquid attracting component covering the surface of the poison bait is absorbed. As shown in FIG. 3 (b), a part of the poison bait was attached to the surface of the wiping cloth collected after 5 seconds together with the attracting component that became liquid. On the other hand, the poison bait of the specimen 2 did not adhere to the wiping cloth surface as shown in FIGS. 4 (a) and 4 (b).
This also shows that the surface condition of the poison bait of the specimen 1 changes with time.
＜喫食試験１＞
　保存後の検体１および２の毒餌剤を用いてムカデの喫食性を評価した。
　検体１および２の保存後の毒餌剤約１ｇを置いたケージ（縦３０ｃｍ、横５０ｃｍ、深さ４０ｃｍ）内に体長約２０ｃｍのトビズムカデを１匹放ち、ムカデが毒餌剤にはじめて接触した際に毒餌剤を喫食するか否かを調べた。試験は５回繰り返して行った。 <Eating test 1>
Using the poisonous baits of Samples 1 and 2 after storage, the eating ability of centipedes was evaluated.
One Tobism cadet about 20 cm in length was released in a cage (length 30 cm, width 50 cm, depth 40 cm) in which about 1 g of the poison bait after storage of specimens 1 and 2 was placed, and when the centipede first contacted the poison bait It was investigated whether or not the agent was eaten. The test was repeated 5 times.
　試験の結果、検体１の毒餌剤を使用した場合、全てのムカデで毒餌剤を喫食したことが確認されたが、検体２の毒餌剤を使用した場合は、全てのムカデが毒餌剤に接近することはあっても、毒餌剤を喫食することはなかった。 As a result of the test, when the poison bait of the specimen 1 was used, it was confirmed that the poison bait was eaten by all the centipedes, but when using the poison bait of the specimen 2, all the centipedes approached the poison bait. I did not eat poisonous bait.
＜喫食試験２＞
　表３に記載の毒餌剤基剤１００重量部に対し、水４．５重量部、エタノール３重量部を加えて混練し、図５（ｂ）に示すような、直径約５ｍｍ、長さ約１０ｍｍの円柱状に成形して毒餌剤を得た（検体３～５）。続いて、得られた各毒餌剤約１ｇを２０～２３℃、湿度１００％の条件下で７２時間保存した。
　保存後の各検体を目視にて観察し、潮解状態となり、毒餌剤の表面が液状物で覆われたものを「〇」、潮解状態が確認できなかったものを「×」として評価した。
　検体３～５の毒餌剤は、経時的に大気中の水分を吸収して誘引成分が潮解し、液状となった誘引成分で表面が覆われた状態となったことが確認された。結果を表３に示す。 <Eating test 2>
4.5 parts by weight of water and 3 parts by weight of ethanol are added to 100 parts by weight of the bait base shown in Table 3 and kneaded. As shown in FIG. 5B, the diameter is about 5 mm and the length is about 10 mm. A poisonous bait was obtained by molding into a cylindrical shape (Samples 3 to 5). Subsequently, about 1 g of each poisonous bait obtained was stored for 72 hours under conditions of 20 to 23 ° C. and 100% humidity.
Each specimen after storage was visually observed to be in a deliquescent state, and the case where the surface of the poison bait was covered with a liquid substance was evaluated as “◯”, and the case where the deliquesce state could not be confirmed was evaluated as “x”.
It was confirmed that the poison baits of Samples 3 to 5 absorbed moisture in the atmosphere over time, and the attracting component was deliquescent, and the surface was covered with the attracting component that became liquid. The results are shown in Table 3.

　次に、検体３～５について保存前と保存後の毒餌剤を用いてムカデの喫食性を評価した。
　検体３～５の保存前と保存後の毒餌剤約１ｇをそれぞれ置いたケージ（縦３０ｃｍ、横５０ｃｍ、深さ４０ｃｍ）内に体長約２０ｃｍのトビズムカデを１匹放ち、ムカデが毒餌剤にはじめて接触した際に毒餌剤を喫食するか否かを調べた。ムカデが喫食したものを「○」、ムカデが喫食しなかったものを「×」と評価した。試験は５回繰り返して行った。また、各検体におけるムカデの致死率も求めた。結果を表４に示す。 Next, the eating habits of centipedes were evaluated for specimens 3 to 5 using poisonous baits before and after storage.
Release a single Tobism cadet about 20 cm long in a cage (length 30 cm, width 50 cm, depth 40 cm) with about 1 g of prey and pre-storage poison baits for specimens 3-5, and the centipede first contacts the poison bait. It was investigated whether or not the poison bait was eaten. What the centipede had eaten was rated as “◯”, and what the centipede did not eat was evaluated as “x”. The test was repeated 5 times. In addition, the centipede lethality in each specimen was also determined. The results are shown in Table 4.

　表４の結果から、表面から重心までの最短距離が２．５ｍｍの毒餌剤において、保存前の毒餌剤では、検体３～５はいずれもムカデの喫食が確認されなかった。しかし保存後の状態において、検体３～５の毒餌剤は、６０％以上の喫食率であり、喫食したムカデは全て致死した。特に保存後の検体３は、すべてのムカデが、毒餌剤を喫食し致死したことが確認された。 From the results shown in Table 4, in the poison bait with the shortest distance from the surface to the center of gravity of 2.5 mm, none of the specimens 3 to 5 was confirmed to be eaten by centipedes in the bait before storage. However, in the state after storage, the poison baits of specimens 3 to 5 had a feeding rate of 60% or more, and all the centipedes that had been eaten were dead. In particular, it was confirmed that all centipedes in the specimen 3 after storage were killed by eating poisonous bait.
＜喫食試験３＞
　表５に記載の毒餌剤基剤１００重量部に対し、水４．５重量部、エタノール３重量部を加えて混練し、図５（ｂ）に示すような、直径約２ｍｍ、長さ約５ｍｍの円柱状に成形して毒餌剤を得た（検体６～１０）。続いて、得られた各毒餌剤約０．５ｇを２０～２３℃、湿度１００％の条件下で４８時間保存した。 <Eating test 3>
4.5 parts by weight of water and 3 parts by weight of ethanol are added to 100 parts by weight of the bait base shown in Table 5 and kneaded. As shown in FIG. 5B, the diameter is about 2 mm and the length is about 5 mm. To obtain a poisonous bait (specimens 6 to 10). Subsequently, about 0.5 g of each poisonous bait obtained was stored for 48 hours at 20-23 ° C. and 100% humidity.
　保存後の各検体を目視にて観察し、前記＜喫食試験２＞と同様に毒餌剤の表面状態を観察した。
　検体６～８の毒餌剤は、経時的に大気中の水分を吸収して誘引成分が潮解し、液状となった誘引成分で表面が覆われた状態となったことが確認されたが、検体９、１０の毒餌剤は、保存後の潮解現象が確認されなかった。
　また、毒餌剤の吸湿による重量増加倍率を上記式により求めた。結果を併せて表６に示す。 Each specimen after storage was visually observed, and the surface state of the poison bait was observed in the same manner as in the <Eating Test 2>.
It was confirmed that the poisonous baits of Samples 6 to 8 absorbed moisture in the atmosphere over time, and the attracting component was deliquescent, and the surface was covered with the attracting component that became liquid. No deliquescent phenomenon after storage was confirmed for the 9 and 10 poison baits.
Moreover, the weight increase rate by moisture absorption of a poison bait was calculated | required by said formula. The results are also shown in Table 6.

　表７の結果から、表面から重心までの最短距離が１ｍｍの毒餌剤において、検体６～８の毒餌剤は、保存前ではいずれもムカデの喫食が確認されなかったが、保存後の状態において、１００％の喫食率であり、喫食したムカデは全て致死した。一方、検体９、１０の毒餌剤は、保存後の状態においてほとんど喫食されず、ムカデが餌と認識しなかったものと考えられる。 From the results in Table 7, in the poison bait with the shortest distance from the surface to the center of gravity of 1 mm, the poison baits of specimens 6 to 8 were not confirmed to eat any centipede before storage, but in the state after storage, The eating rate was 100%, and all the centipedes that were eaten were deadly. On the other hand, it is considered that the poisonous baits of the specimens 9 and 10 were hardly eaten in the state after storage, and the centipede did not recognize the bait.
＜喫食試験４＞
　表８に記載の毒餌剤基剤１００重量部に対し、水４．５重量部、エタノール３重量部を加えて混練し、図５（ａ）に示すような、直径約２０ｍｍ、厚み約２０ｍｍの円盤状に打錠して毒餌剤を得た（検体１１～１３）。続いて、得られた各毒餌剤の約５～８ｇを、２０～２３℃、湿度１００％の条件下で４８時間保存した。 <Eating test 4>
To 100 parts by weight of the bait base shown in Table 8, 4.5 parts by weight of water and 3 parts by weight of ethanol are added and kneaded, and as shown in FIG. 5 (a), the diameter is about 20 mm and the thickness is about 20 mm. Tableting was performed in a disk shape to obtain a poison bait (Samples 11 to 13). Subsequently, about 5 to 8 g of each poisonous bait obtained was stored for 48 hours under the conditions of 20 to 23 ° C. and 100% humidity.
　保存後の各検体を目視にて観察し、前記＜喫食試験２＞と同様に毒餌剤の表面状態を観察した。
　検体１１、１２の毒餌剤は、経時的に大気中の水分を吸収して誘引成分が潮解し、液状となった誘引成分で表面が覆われた状態となったことが確認されたが、検体１３の毒餌剤は、保存後の潮解現象は確認されなかった。
　また、毒餌剤の吸湿による重量増加倍率を上記式により求めた。結果を併せて表９に示す。 Each specimen after storage was visually observed, and the surface state of the poison bait was observed in the same manner as in the <Eating Test 2>.
It was confirmed that the poisonous baits of Samples 11 and 12 absorbed moisture in the atmosphere over time, and the attracting component was deliquescent, and the surface was covered with the attracting component that became liquid. Thirteen poison baits did not show deliquescence after storage.
Moreover, the weight increase rate by moisture absorption of a poison bait was calculated | required by said formula. The results are also shown in Table 9.

　次に、検体１１～１３について、前記＜喫食試験２＞と同様にしてムカデの喫食性を評価し、致死率を求めた。なお、毒餌剤は約５～８ｇを使用し、試験は６回繰り返して行った。結果を表１０に示す。 Next, with respect to the specimens 11 to 13, the eating ability of the centipede was evaluated in the same manner as in the <eating test 2>, and the lethality was obtained. The poison bait was used in an amount of about 5 to 8 g, and the test was repeated 6 times. The results are shown in Table 10.

　表１０の結果から、表面から重心までの最短距離が１０ｍｍの毒餌剤において、誘引成分を８０重量％以上含有させた検体１１、１２は潮解状態となり、保存後のものにおいてはムカデの喫食性を高めることができることがわかった。 From the results in Table 10, in the poisonous bait with the shortest distance from the surface to the center of gravity of 10 mm, the specimens 11 and 12 containing at least 80% by weight of the attracting component are in a deliquescent state. It turned out that it can raise.
