The present invention relates to a means for rapidly incorporating a small animal control agent into the body of a small animal.
　従来、小動物防除性樹脂組成物としては、ベース樹脂中に、小動物防除剤と、小動物防除剤を溶解保持して徐放性を付与する徐放助剤とを混練したもの（例えば、特許文献１参照。）や、ベース樹脂中に、小動物防除剤と、ベース樹脂に対する小動物防除剤の親和性を高める親和性樹脂とを混練したもの（例えば、特許文献２参照。）等が知られている。 Conventionally, as a small animal controllable resin composition, a base animal is kneaded with a small animal control agent and a sustained release assistant that dissolves and holds the small animal control agent to give sustained release (for example, Patent Document 1). And a mixture of a small animal control agent and an affinity resin that increases the affinity of the small animal control agent for the base resin (for example, see Patent Document 2).
　特許文献１に記載の小動物防除性樹脂組成物は、ベース樹脂中に小動物防除剤の徐放助剤を混練したので、小動物防除性能を長期にわたって発現することができる。また、特許文献１に記載の小動物防除性樹脂組成物は、ベース樹脂として、ポリアミド樹脂及びポリアセタール樹脂より選ばれる少なくとも１種の樹脂を用いているので、その成形体は、各種構造部材として使用可能な強度、耐熱性及び耐薬品性を有している。 Since the small animal control resin composition described in Patent Document 1 kneads the small animal control agent sustained release aid in the base resin, the small animal control performance can be exhibited over a long period of time.

　ところで、小動物防除性樹脂組成物及びこれを用いた小動物防除性樹脂成形体には、その基本的な性能として、有害な小動物に対する小動物防除剤の速効性が高いことが求められる。このような性能は、小動物防除性樹脂組成物又は小動物防除性樹脂成形体に接触した小動物の体表面に、小動物防除剤を効率よく移行させること、及び、体表面に移行した小動物防除剤を小動物の体内に効率よく取り込ませることにより発揮される。 By the way, a small animal control resin composition and a small animal control resin molded body using the same are required to have a fast action of a small animal control agent for harmful small animals as a basic performance. Such performance is achieved by efficiently transferring the small animal control agent to the surface of the small animal body that has been in contact with the small animal control resin composition or the small animal control resin molded product, and the small animal control agent transferred to the body surface of the small animal. It is demonstrated by efficiently taking it into the body.
　特に、近年においては、小動物防除剤に対する耐性を持った小動物が増えていることから、従来よりも大量の小動物防除剤を効率よく小動物の体表面に付着させること、及び、体表面に移行した小動物防除剤を小動物の体内に速やかに取り込ませることが、重要な技術的課題になっている。 In particular, in recent years, since the number of small animals having resistance to small animal control agents has increased, it is possible to attach a large amount of small animal control agents to the body surface of small animals more efficiently than before, and small animals that have migrated to the body surface It is an important technical problem to rapidly incorporate a control agent into the body of a small animal.
　しかしながら、従来においては、大量の小動物防除剤を効率よく小動物の体表面に付着させる、体表面に移行した小動物防除剤を小動物の体内に速やかに取り込ませる、という発想自体が知られておらず、小動物防除性樹脂組成物又は小動物防除性樹脂成形体中の小動物防除剤の添加量を増加することにより対処しようとするものがほとんどである。このため、高性能の小動物防除性樹脂組成物及び小動物防除性樹脂成形体は、高コストになりやすいという問題がある。 However, in the past, the idea itself of efficiently attaching a large amount of a small animal control agent to the surface of a small animal body, and allowing a small animal control agent transferred to the body surface to be quickly taken into the body of the small animal is not known, Most attempts are made to cope by increasing the amount of the small animal control agent in the small animal control resin composition or the small animal control resin molding. For this reason, a high performance small animal control resin composition and a small animal control resin molding have the problem that it becomes high cost easily.
　本発明は、このような従来技術の実情に鑑みてなされたものであり、その目的は、有害な小動物に対する速効性が高い小動物防除性樹脂組成物及び小動物防除性樹脂成形体を提供することにある。 The present invention has been made in view of such a state of the art, and an object of the present invention is to provide a small animal control resin composition and a small animal control resin molded article having a high immediate effect on harmful small animals. is there.

　生物の体表面は、皮膚腺から放出される炭化水素を含む蝋で覆われている。従って、小動物防除性樹脂組成物又は小動物防除性樹脂成形体に添加剤として炭化水素系化合物を添加すると、小動物防除剤を含む炭化水素系化合物と生物の体表面との親和性が高められ、小動物防除性樹脂組成物又は小動物防除性樹脂成形体の表面に徐放された小動物防除剤を効率よく小動物の体表面に移行させることができる。よって、小動物防除剤の速効性を高めることができる。 The biological body surface is covered with wax containing hydrocarbons released from the skin glands. Therefore, when a hydrocarbon compound is added as an additive to the small animal control resin composition or the small animal control resin molded article, the affinity between the hydrocarbon compound containing the small animal control agent and the body surface of the organism is increased, and the small animal The small animal control agent slowly released on the surface of the control resin composition or the small animal control resin molding can be efficiently transferred to the surface of the small animal.

Therefore, a large amount of the small animal control agent contained in the hydrocarbon compound can be transferred to the body surface of the small animal, and the effectiveness of the small animal control agent can be exhibited even for a small animal having resistance.

Those having fluidity can be used as, for example, paints, and those having semi-fluidity can be used as, for example, sealing agents. Further, those having rubber-like elasticity can be used as cushioning materials or stuffing.

　殺虫速効性試験は、チャバネゴキブリを実施例１～３２及び比較例１～２２の実験試料に継続的に接触させ、５０％のチャバネゴキブリがノックダウンするまでにかかった時間（ＫＴ－５０）を測定することにより行った。より具体的には、実施例１～３２及び比較例１～２２に係る実験試料から、一辺が５０ｍｍの四角形のピースを切り取り、これを縦が５５ｍｍ、横が５５ｍｍ、高さが５５ｍｍの有底の試験容器の内側底面に設置し、この試験容器内に１０匹のチャバネゴキブリを投入し、５匹のチャバネゴキブリがノックダウンするまでにかかった時間を測定した。なお、試験容器の内側壁面には、炭酸カルシウムの粉末を塗布してチャバネゴキブリが逃げ出さないようにし、チャバネゴキブリを継続的に実験試料に接触させた。その結果、図４～図６のデータを得た。 <Insecticide fast-acting test>
The insecticidal fast-acting test measures the time (KT-50) required for 50% German cockroaches to be knocked down by continuously contacting German cockroaches with the experimental samples of Examples 1-32 and Comparative Examples 1-22. Was done. More specifically, a square piece having a side of 50 mm is cut out from the experimental samples according to Examples 1 to 32 and Comparative Examples 1 to 22, and this piece is bottomed with a length of 55 mm, a width of 55 mm, and a height of 55 mm. Was installed on the inner bottom surface of the test vessel, 10 German cockroaches were put into the test vessel, and the time taken for the 5 German cockroaches to be knocked down was measured. Note that calcium carbonate powder was applied to the inner wall surface of the test container so that the cockroaches did not escape, and the cockroaches were continuously brought into contact with the experimental sample. As a result, data shown in FIGS. 4 to 6 were obtained.
　また、図４～図６のデータから、実施例１～８、実施例９～１６、実施例１７～２４、実施例２５～３２のそれぞれについて、パラフィンオイルの分子量に対するＫＴ－５０のデータ及びパラフィンオイルの動粘度に対するＫＴ－５０のデータをプロットして、図７～図１４のデータを得た。また、図７～図１４には、実施例１～８に対応する比較例１のデータ、実施例９～１６に対応する比較例２のデータ、実施例１７～２４に対応する比較例３～２１のデータ、実施例２５～３２に対応する比較例２２のデータを併せて示した。 Further, from the data of FIGS. 4 to 6, for each of Examples 1 to 8, Examples 9 to 16, Examples 17 to 24, and Examples 25 to 32, KT-50 data with respect to the molecular weight of paraffin oil and paraffin Plotting the KT-50 data against the kinematic viscosity of the oil gave the data of FIGS. 7 to 14 show data of Comparative Example 1 corresponding to Examples 1 to 8, data of Comparative Example 2 corresponding to Examples 9 to 16, and Comparative Examples 3 to 3 corresponding to Examples 17 to 24. 21 data and the data of Comparative Example 22 corresponding to Examples 25 to 32 are also shown.
　図７、図９、図１１、図１３から明らかなように、ベース樹脂の種類によらず、パラフィンオイルの分子量に対するＫＴ－５０の変化の傾向はほぼ同一であり、分子量が３３０～５３０の範囲で、比較例に係る小動物防除性樹脂組成物及び小動物防除性樹脂成形体よりも、ＫＴ－５０が改善されている。これは、分子量が３３０～５３０程度の低分子量のパラフィンオイルは、害虫の体孔から体内に入り込みやすいためであると考察される。 As is clear from FIGS. 7, 9, 11, and 13, the change in KT-50 with respect to the molecular weight of paraffin oil is almost the same regardless of the type of base resin, and the molecular weight ranges from 330 to 530. Thus, KT-50 is improved over the small animal control resin composition and the small animal control resin molding according to the comparative example. This is considered to be because low molecular weight paraffin oil having a molecular weight of about 330 to 530 tends to enter the body through the body holes of pests.
　図８、図１０、図１２、図１４から明らかなように、ベース樹脂の種類によらず、パラフィンオイルの動粘度に対するＫＴ－５０の変化の傾向はほぼ同一であり、動粘度が１０～１２０ｃＳｔの範囲で、比較例に係る小動物防除性樹脂組成物及び小動物防除性樹脂成形体よりも、ＫＴ－５０が改善されている。これは、動粘度が１０～１２０ｃＳｔ程度の低粘度のパラフィンオイルは、害虫の体表面に移行されやすいためであると考察される。 As is apparent from FIGS. 8, 10, 12, and 14, the tendency of the change in KT-50 with respect to the kinematic viscosity of paraffin oil is almost the same regardless of the type of the base resin, and the kinematic viscosity is 10 to 120 cSt. In this range, KT-50 is improved over the small animal control resin composition and the small animal control resin molding according to the comparative example. This is considered to be because low viscosity paraffin oil having a kinematic viscosity of about 10 to 120 cSt is easily transferred to the body surface of the pest.
〈害虫忌避率試験〉
　害虫忌避率の評価は、シェルター試験により行った。具体的には、上部が開放された有底の試験容器（縦３００ｍｍ、横２３０ｍｍ、高さ２５０ｍｍ）内に、餌及び水と、害虫が隠れることのできる２つのシェルター（縦６０ｍｍ、横６０ｍｍ、高さ１０ｍｍ）Ａ、Ｂを置いた。シェルターＡは、内部に実施例１～３２及び比較例１～２２に係る実験試料（一辺の長さが５０ｍｍの正方形）をそれぞれ設置したものとし、シェルターＢは、内部に前記実験試料を設置しないものとした。前記試験容器内にチャバネゴキブリ１０匹を投入して放置し、１０時間放置した後に、前記試験容器からシェルターＡ，Ｂを取り出して、それぞれのシェルター内にいるチャバネゴキブリの数を数え、忌避率[％]＝｛（シェルターＢの虫の数－シェルターＡの虫の数）／シェルターＢの虫の数｝×１００の式により、忌避率を算出した。 <Pest repellent rate test>
The pest repellent rate was evaluated by a shelter test. Specifically, two shelters (length 60 mm, width 60 mm, width 60 mm, width 60 mm, food and water) and pests can be hidden in a bottomed test container (length 300 mm, width 230 mm, height 250 mm) with an open top. 10 mm in height) A and B were placed. In the shelter A, experimental samples according to Examples 1 to 32 and Comparative Examples 1 to 22 (a square having a side length of 50 mm) are installed, and in the shelter B, the experimental sample is not installed. It was supposed to be. Put 10 German cockroaches in the test container and let them stand for 10 hours. Then, take out the shelters A and B from the test container, count the number of German cockroaches in each shelter, and repel the rate [%]. = ((Number of shelter B worms−number of shelter A worms) / number of shelter B worms) × 100, the repelling rate was calculated.
　図４～図６に示すように、実施例１～３２及び比較例１～２２に係る実験試料は、いずれも害虫忌避率が１００％であった。このことから、実施例１～３２に係る小動物防除性樹脂組成物及び小動物防除性樹脂成形体は、高い害虫忌避率を発揮するだけでなく、殺虫速効性についても高い性能を発揮することが分かる。 As shown in FIGS. 4 to 6, the experimental samples according to Examples 1 to 32 and Comparative Examples 1 to 22 all had a pest repellent rate of 100%. From this, it can be seen that the small animal control resin composition and the small animal control resin moldings according to Examples 1 to 32 not only exhibit a high insect repellent rate, but also exhibit high performance with respect to insecticidal rapid efficacy. .
