Abstract
Description
本発明は、アリ類のなかでも特にヒアリ類を対象としたアリ類防除剤に関し、具体的には、採餌アリによるベイト剤の巣への運搬効率を高め、かつ、巣内の働きアリによるアリ類防除成分の巣内伝播効率をも高めたアリ類防除剤に関するものである。 TECHNICAL FIELD The present invention relates to an ant-controlling agent particularly directed to fireflies among ants, and more specifically, to enhance the efficiency of transporting bait agent to the nest by the feeding ants and by the worker ant in the nest The present invention relates to an ant-control agent which enhances the in-nest propagation efficiency of an ant-control component.
近年、屋外から家屋内に侵入するアリ類の被害や苦情が増加し、アリ類は重要な不快害虫の一つにあげられている。従来、これらアリ類の防除方法として、大きくは、（１）殺虫成分を含有する液剤やエアゾール等を散布する、（２）ベイト剤等を喫食させて巣に持ち帰らせ巣ごと退治する、（３）人体や家屋の入り口あるいは周辺等に予めアリ忌避剤を施用してアリ類を忌避させる方法があり、このうち、（２）の方法が巣ごと撲滅でき効率的であるとされてきた。このため、ベイト剤の喫食性もしくは運搬性を高めるために誘引成分やベイト処方等に関して、これまで数多くの発明や改良が提案されている。
例えば、特開２０１７−８０１５号公報（特許文献１）には、落花生油および炭素数３〜４の多価アルコールを含有するアリ用誘引剤が記載され、各種アリ類に対して高い誘引性を発揮するとしている。また、特表２０１２−５０９８５４号公報（特許文献２）は、殺虫剤および餌組成物を含む固体蟻餌であって、餌組成物が、ａ）５〜９５重量％の植物粉、ｂ）１〜６０重量％のタンパク質源、ｃ）５〜６０重量％の砂糖、および、ｄ）０．１〜１０重量％のポリマーバインダー（各重量％は餌組成物に関する）を含む、前記固体蟻餌を開示し、当該蟻餌は０．２〜２ｍｍの長さおよび０．２〜２ｍｍの直径を有する円筒形状を有する顆粒が好ましい旨述べているが、この粒径は顆粒の製造性の観点から言及されたものであるなど、いずれの提案においてもアリ類の習性が十分研究されているわけではなく、防除効果も満足のいくものではない。
In recent years, the damage and complaints of ants that invade the house from outside have increased, and ants are mentioned as one of the important unpleasant pests. Conventionally, as a method of controlling these ants, (1) a solution containing an insecticidal component, an aerosol or the like is dispersed, (2) a bait preparation is eaten and brought back to the nest, and the nest is eliminated (3 2.) There is a method of applying ant repellant beforehand to the human body or at the entrance or periphery of a house to repel ants. Among them, the method of (2) has been considered to be effective because it can destroy the whole nest. Therefore, many inventions and improvements have been proposed with regard to an attractant component, a bait formulation and the like in order to enhance the eating property or the transportability of the bait.
For example, Japanese Patent Application Laid-Open No. 2017-8015 (Patent Document 1) describes an attractant for ant which contains peanut oil and a polyhydric alcohol having 3 to 4 carbon atoms, and is highly attractive to various ant species. It is supposed to be effective. In addition, JP 2012-509854A (Patent Document 2) is a solid ant bait comprising an insecticide and a bait composition, and the bait composition comprises a) 5 to 95% by weight of plant powder, b) 1 Said solid ant bait comprising: ̃60% by weight protein source, c) 5 ̃60% by weight sugar, and d) 0.1 ̃10% by weight polymer binder (each% by weight relates to the bait composition) Although it is disclosed that said ant bait is preferably a granule having a cylindrical shape having a length of 0.2 to 2 mm and a diameter of 0.2 to 2 mm, this particle size is mentioned from the viewpoint of the production of granules The habits of ants have not been sufficiently studied in any of the proposals, and the control effect is not satisfactory.
ところで、アリ類は、一般に、巣の外で餌を採集する働きアリ（以降、採餌アリと称する）と、巣内で巣造り、子育て、巣の防衛を担当する働きアリが分業特化し、女王アリを中心とした集団は、栄養交換やグルーミングを介したケミカルコミュニケーションによって同類であることを認識しながら社会生活を営んでいる。アリ類の社会行動を観察すると、採餌アリは、液状もしくはペースト状の餌を体内に吸い取り素嚢に蓄えて持ち帰る一方、固形状の餌については運べる大きさに細かくして巣内に運び込む。そして、こうした固形状の餌は巣内の幼虫だけが消化することができ、その吐き戻し液は成虫の働きアリの餌となり、更に栄養交換によって女王アリに受け渡されることが知られている。 By the way, ants are, in general, worker ants that collect food outside the nest (hereinafter referred to as foraging ants) and worker ants that are responsible for nesting, parenting, and nest defense in the nest are specialized divisions, The group centered on the queen ants carries out social life while recognizing that they are similar by chemical communication through nutrient exchange and grooming. When observing the social behavior of the ants, the feeding ants suck liquid or paste-like food into the body and store them in the body capsule and bring them back, while the solid food is finely carried into the nest to a size that can be carried. And, it is known that such solid feed can be digested only by the larvae in the nest, and the regurgitation liquid is feed for adult worker's termites and is further delivered to the queen's term by nutrient exchange.
最近、特定外来生物に指定されている「ヒアリ」や「カミアリ」等（以降、ヒアリ類と称する）が日本数箇所で発見され、強い毒を持ち、繁殖力が高いことから大きな社会問題になっている。このヒアリ類は、地中深くコロニーを造り、一つのコロニーの中に１匹の女王アリからなる単女王制であるものと、複数の女王アリからなる多女王制の２種類が存在する。そして、多女王制の場合、女王アリの数が多ければ多いほど繁殖力が強く、最大で４０００万匹も生活するコロニーが存在するなど、その生態は在来アリ類とは大きく異なっている。このため、前記（２）のベイト剤による防除方法を、多女王制の「ヒアリ類」のコロニーに適用しても、一部の女王アリはそのベイト剤の存在をいち早く察知し、作用効果を免れて離散することも知られている。このように、ヒアリ類の防除は在来アリ類に比べて難しいと言われており、的確な防除対策の構築が急務となっている。 Recently, “hyari” and “chauri” (hereinafter referred to as fireflies), etc. designated as specific alien species (hereinafter referred to as fireflies) have been found in several places in Japan, have strong poisons, and are highly productive due to their high fertility. ing. There are two kinds of fireflies, which form colonies deep in the ground and are single-feet system consisting of one queen ant in one colony and polyqueen system consisting of multiple queen ant. And in the case of multi-queen system, the larger the number of queen ants, the stronger the breeding power, and there are colonies that live up to 40 million animals, so their ecology is very different from traditional ants. Therefore, even if the bait preparation method described in (2) above is applied to a colony of "feathers" of multiple femininity, some queen ants quickly detect the presence of the bait preparation, and their action and effect are It is also known to escape and break away. Thus, it is said that the control of fire ants is difficult compared to conventional ants, and the construction of an appropriate control measure is urgently needed.
かかる現状を踏まえ、ベイト剤を施用してアリ類、特に「ヒアリ類」を防除するにあたっては、採餌アリにベイト剤を巣に効率的に運搬させることはもちろんのこと、ベイト剤に含まれる遅効性のアリ類防除成分を働きアリによって速やかに巣内のコロニー全体に伝播させることがより一層肝要となる。
上述したアリ類の習性を考慮すると、ベイト剤に配合する誘引もしくは摂食刺激成分としては、固形状のものに比べると運搬性や伝播性の点で有利な、液状もしくはペースト状の餌を主体に用いる方が合理的と考えられる。しかるに、本発明者らが鋭意検討を重ねた結果、そのメカニズムは不明ながら、液状もしくはペースト状成分と固形状成分を特定比率で混用して誘引もしくは摂食刺激成分の組成を決定するとともに、ベイト剤の平均粒径を特定することによって、ベイト剤の巣への運搬効率を高め、かつ、アリ類防除成分の巣内伝播効率をも高め得ることを見出し、本発明を完成するに至った。
すなわち、本発明は、アリ類のなかでも特にヒアリ類に対して有効なベイト剤であって、効果的な防除が可能なアリ類防除剤を提供することを目的とする。
Based on this current situation, when applying bait to control ants, particularly "frying birds", it is included in bait as well as to efficiently transport bait to the nest by feeding ants It is even more important that the late-acting ants control component be rapidly transmitted by the worker ants to the entire colony in the nest.
Taking into consideration the habits of ants mentioned above, the attractive or feeding stimulant component to be added to the bait is mainly a liquid or paste-like bait which is advantageous in terms of transportability and spreadability as compared with solid ones. It is considered rational to use it for However, as a result of extensive investigations by the present inventors, the mechanism is unknown, and the composition of the attraction or feeding stimulation component is determined by mixing the liquid or paste-like component and the solid component at a specific ratio, and By identifying the average particle size of the agent, it is found that the efficiency of transporting bait agent to the nest can be enhanced, and the efficiency of in-nest transmission of the ant-controlling ingredient can also be enhanced, and the present invention has been completed.
That is, an object of the present invention is to provide an ant control agent which is an effective bait agent particularly for fire ants among ants and which can be effectively controlled.

The present invention has been found out that the following constitution has excellent effects to achieve the above object.
(1) 0.05 to 10% by mass of a late-acting ant-controlling ingredient (a), 5.0 to 70% by mass of an attraction or feeding stimulation component (b) to an ant, and c) a bait containing
The attraction or feeding stimulation component (b) to the ants is 1.0 to 20% by mass of the liquid or pasty component (b-1) with respect to the total amount of bait, and 4 for the total amount of the bait And (b-1) / (b-2) ratio is 1/2 to 1/40, and the bait agent is With an average particle size of 0.02 to 3.0 mm, the delivery efficiency of the bait to the nest by the feeding ants is enhanced, and the intra-nest transmission efficiency of the ant-controlling ingredient by the workers in the nest is also enhanced. Ant control agent which enhanced.
(2) The attraction or feeding stimulation component (b) to the ants comprises 1.5 to 15% by mass of the liquid or paste-like component (b-1) with respect to the total amount of bait agent, and the total amount of bait agent To 10 to 45% by mass of the solid component (b-2), and the ratio (b-1) / (b-2) is 1/5 to 1/30, and the bait agent The ants control agent as described in (1) whose average particle diameter of is 0.5-2.0 mm.

本発明のアリ類防除剤は、ベイト剤に配合する誘引もしくは摂食刺激成分として、液状もしくはペースト状成分と固形状成分を特定比率で混用して処方化するとともに、ベイト剤の平均粒径を特定することによって、ベイト剤の巣への運搬効率を高め、かつ、アリ類防除成分の巣内伝播効率をも高め得るので、アリ類、特にヒアリ類に対して極めて実用的な防除効果を示す。
The ants control agent of the present invention is formulated by mixing a liquid or paste-like component and a solid component at a specific ratio as an attractive or feed stimulating component to be added to the bait, and the average particle diameter of the bait is By specifying it, it is possible to enhance the efficiency of transporting bait agent to the nest and also enhance the efficiency of in-nest transmission of the ant-controlling component, so that it exhibits a very practical control effect on ants, in particular the fire ants. .
本発明のアリ類防除剤は、遅効性のアリ類防除成分（ａ）を０．０５〜１０質量％と、アリ類に対する誘引もしくは摂食刺激成分（ｂ）を５．０〜７０質量％と、ベイト剤基材（ｃ）を含有するベイト剤である。
ここで、遅効性のアリ類防除成分を用いるのは、採餌アリにベイト剤を巣に持ち帰らせた後、巣内のコロニー全体にアリ類防除成分を伝播させて巣全体の撲滅を図るためで、採餌アリを速効的に殺してはこのような作用効果が得られないからである。
かかる遅効性のアリ類防除成分（ａ）としては、ピレスロイド剤に見られるような速効性を呈しない防除成分を包含し、例えば、アミノヒドラジン系殺虫剤のヒドラメチルノン、ケイ素系殺虫剤のシラフルオフェン、オキサジアゾン系殺虫剤のインドキサカルブ、幼若ホルモン様活性物質のピリプロキシフェンやメトプレン、ネオニコチノイド系殺虫剤のジノテフランやアセタミプリド、キチン合成阻害剤のビストリフルロン、テフルベンズロン、クロルフルアズロンやフルフェノクスロン等を例示できるがこれらに限定されない。
なかでも、ヒドラメチルノン、シラフルオフェン、ピリプロキシフェン、ジノテフラン及びビストリフルロンが好適に用いられる。
アリ類防除成分（ａ）のベイト剤全体量に対する配合量は０．０５〜１０質量％の範囲が適当である。０．０５質量％未満ではアリ類に対する防除効果が期待できないし、一方、１０質量％を越えると、遅効性の防除成分とはいえ、速効的な作用も幾分呈しえるので本発明の趣旨に合致しない懸念を有する。
The ants control agent of the present invention comprises 0.05 to 10% by mass of the late-acting ants control component (a) and 5.0 to 70% by mass of the attractive or feeding stimulant component (b) to the ants. And a bait containing a bait base (c).
Here, the use of a delayed-acting ant control component is to transmit the ant control component to the entire colony in the nest after causing the feeding ants to bring the bait agent back to the nest, and thereby eliminate the entire nest. Therefore, it is because such an effect can not be obtained by killing foraging ants quickly.
Such a late-acting ant-controlling ingredient (a) includes controlling ingredients which do not exhibit a rapid-acting effect as found in pyrethroids, and examples thereof include hydramethylnon, which is an aminohydrazine insecticide, and silafluofen, which is a siliconic insecticide. , The oxadiazonic insecticides indoxacarb, juvenile hormone-like active substances pyriproxyfen and methoprene, neonicotinoid insecticides dinotefuran and acetamiprid, chitin synthesis inhibitors bistrifluron, teflubenzurone, chlorfluazuron and Examples include flufenoxuron and the like, but are not limited thereto.
Among these, hydramethylnon, silafluophene, pyriproxyfen, dinotefuran and bistrifluron are preferably used.
The compounding amount with respect to the total amount of bait agent of the ant controlling ingredient (a) is suitably in the range of 0.05 to 10% by mass. If the amount is less than 0.05% by mass, the control effect against ants can not be expected, while if it exceeds 10% by mass, although it is a late-acting control component, it can exhibit some rapid action, so I have a concern that does not match.
本発明のベイト剤は、アリ類に対する誘引もしくは摂食刺激成分（ｂ）をベイト剤全体量に対して５．０〜７０質量％含有し、この成分（ｂ）は、ベイト剤全体量に対して１．０〜２０質量％、好ましくは１．５〜１５質量％の液状もしくはペースト状成分（ｂ−１）と、ベイト剤全体量に対して４．０〜５０質量％、好ましくは１０〜４５質量％の固形状成分（ｂ−２）とから構成される。そして、ベイト剤の平均粒径を０．０２〜３．０ｍｍ、好ましくは０．５〜２．０ｍｍとなし、採餌アリによるベイト剤の巣への運搬効率を高め、かつ、巣内の働きアリによるアリ類防除成分の巣内伝播効率をも高めたことに特徴を有するものである。
ここで、成分（ｂ）が５．０質量％未満であるとアリ類に対する誘引もしくは摂食刺激作用が不足し、一方、７０質量％を越えて配合すると忌避的な作用を生じる恐れがあるので好ましくない。
The bait agent of the present invention contains 5.0 to 70% by mass of an attraction or feeding stimulation component (b) to ants with respect to the total amount of the bait agent, and this component (b) is relative to the total amount of the bait agent 1.0 to 20% by mass, preferably 1.5 to 15% by mass of the liquid or paste-like component (b-1) and 4.0 to 50% by mass, preferably 10 to 10% by mass relative to the total amount of bait It consists of 45 mass% solid-like component (b-2). And, the average particle size of bait agent is 0.02 to 3.0 mm, preferably 0.5 to 2.0 mm, and the transport efficiency to the nest of bait agent by feeding ants is enhanced, and the function in the nest It is characterized in that the in-nest transmission efficiency of the ant-controlling component by ants is also enhanced.
Here, if the component (b) is less than 5.0% by mass, the attractiveness or feeding-stimulating effect on ants is insufficient, while if it exceeds 70% by mass, it may cause an repellent action. Not desirable.
従来の技術によれば、成分（ｂ）を構成するにあたり、液状もしくはペースト状成分（ｂ−１）主体が有利と考えられたが、本発明者らが鋭意検討を重ねた結果、成分（ｂ−１）よりも成分（ｂ−２）の構成比率を高くし、具体的には、その（ｂ−１）／（ｂ−２）比率を１／２〜１／４０、好ましくは、１／５〜１／３０に特定することによって、最適な結果が得られることを知見したのである。
すなわち、液状もしくはペースト状成分（ｂ−１）は、採餌アリが小さな素嚢に蓄えて巣に持ち帰り、巣内の働きアリ成虫に移され栄養交換に供される。一方、採餌アリが持ち抱えて巣内に運び込んだ固形状成分（ｂ−２）は、働きアリの幼虫によって吐き戻し液に消化された後、働きアリ成虫に移され、前述の成分（ｂ−１）とブレンドされた形で栄養交換に供される。その明確なメカニズムは不明であるが、成分（ｂ−１）と吐き戻し液が協働して、アリ類防除成分の巣内伝播効率向上に大きく貢献するものと考えられる。
なお、本発明では、液状もしくはペースト状成分（ｂ−１）は、固形状成分（ｂ−２）と均一状に混和されてもよいし、固形状成分（ｂ−２）を覆うようにしてベイト剤を形成してもよく、いずれであっても、高い運搬効率とアリ類防除成分の優れた巣内伝播効率が達成される。
According to the prior art, the liquid or paste-like component (b-1) was considered to be advantageous in constituting the component (b), but as a result of intensive studies by the present inventors, the component (b Component (b-2) is higher than that of (-1), and specifically, the (b-1) / (b-2) ratio is 1/2 to 1/40, preferably 1 / It has been found that by specifying 5 to 1/30, optimum results can be obtained.
That is, for the liquid or pasty component (b-1), the feeding ants are stored in a small body bag and brought back to the nest, transferred to an adult worker ant in the nest and subjected to nutrient exchange. On the other hand, the solid component (b-2) carried by the feeding ants and carried into the nest is digested by the larva of the worker ants in the regurgitation solution and then transferred to the adult worker ant, and the aforementioned component (b It is provided for nutrient exchange in the form blended with -1). Although the clear mechanism is unknown, it is thought that a component (b-1) and a regurgitation liquid cooperate and it greatly contributes to the in-nest propagation efficiency improvement of an ant-like control component.
In the present invention, the liquid or paste-like component (b-1) may be uniformly mixed with the solid-like component (b-2), or the solid-like component (b-2) may be covered. A bait may be formed, and in any case high transport efficiency and excellent in-nest transmission efficiency of the ant control component are achieved.
液状もしくはペースト状成分（ｂ−１）としては、植物油及び／又は糖蜜が代表的である。植物油には、例えば、大豆油、米糠油、ピーナッツ油、オリーブ油、コーン油、ゴマ油、ヤシ油、ヒマワリ油、ヒマシ油、ナタネ油、落花生油及びトウモロコシ油等があり、アリ類に対する誘引もしくは摂食刺激作用は、主としてこれらに含まれるオレイン酸、リノール酸、パルミチン酸等に起因するものと考えられている。
一方、本発明で言う糖蜜には、糖分を含んだ液体、シロップ、糖蜜、蜂蜜、砂糖を原料から精製するときに現れる副産物、モラセス、廃糖蜜などが含まれる。
アリ類の種によって誘引もしくは摂食刺激成分（ｂ）に対する嗜好性に差が見られるので、本発明では、植物油及び糖蜜を混用して液状もしくはペースト状（ｂ−１）成分を構成するのが好ましい。
As a liquid or paste-like component (b-1), vegetable oil and / or molasses are representative. Vegetable oils include, for example, soybean oil, rice bran oil, peanut oil, olive oil, corn oil, sesame oil, coconut oil, sunflower oil, castor oil, rapeseed oil, peanut oil and corn oil etc. The stimulant action is considered to be mainly attributable to oleic acid, linoleic acid, palmitic acid and the like contained therein.
On the other hand, the molasses referred to in the present invention includes liquids containing sugar, syrups, molasses, honey, by-products appearing when refining sugar from raw materials, molasses, waste molasses and the like.
Since there is a difference in the preference for the attraction or feeding stimulation component (b) depending on the species of the ant, in the present invention, the vegetable oil and the molasses are mixed to form a liquid or paste-like (b-1) component. preferable.
これに対し、誘引もしくは摂食刺激成分（ｂ）の固形状成分（ｂ−２）としては、蛋白質粉が代表的にあげられる。蛋白質粉のうち動物性蛋白質粉として、例えば、昆虫の粉（乾燥アカムシ粉、サナギ粉など）、鶏卵末、魚粉、エビ粉等があり、また、グロブリン、グルテン等の植物性蛋白質粉も使用可能である。
なお、後述する砂糖、三温糖、ショ糖のような糖質粉に、誘引もしくは摂食刺激成分（ｂ）の固形状成分（ｂ−２）としての作用が幾分か認められる場合もある得るが、これらはベイト剤成形上の役割が大きいので、本発明ではベイト剤基材（ｃ）に含めるものとする。
On the other hand, protein powder is typically mentioned as a solid-like component (b-2) of an attraction or feed stimulation component (b). Among protein powders, as animal protein powder, for example, insect powder (dry akamushi powder, sanagi powder etc.), chicken egg powder, fish powder, shrimp powder etc. are available, and vegetable protein powder such as globulin and gluten can also be used It is.
In addition, the action as a solid-like component (b-2) of an attraction or feeding stimulation component (b) may be recognized in sugar powder like sugar, a three-point sugar, sucrose mentioned later. Although they can be obtained, since they play a large role in bait forming, they are included in the bait base (c) in the present invention.
本発明のアリ類防除剤は、更にベイト剤基材（ｃ）を含有し、ベイト剤を構成する。このような基材としては、小麦粉、米粉、トウモロコシ粉、きな粉のような穀物粉、砂糖、三温糖、黒砂糖、ショ糖、グラニュー糖のような糖質粉、粘土類（カオリン、ベントナイト類等）、タルク類等の鉱物質粉末、ソルビタン脂肪酸エステル類、ショ糖脂肪酸エステル類、ポリオキシエチレン硬化ヒマシ油等の界面活性剤、カゼイン、ゼラチン、カルボキシメチルセルロース（ＣＭＣ）、ポリビニルアルコール、ポリアクリル酸ナトリウム、アラビアゴム、キサンタンガム等の固着剤、結合剤、増粘剤や分散剤があげられる。また、本発明の趣旨に支障を来たさない限りにおいて、ＢＨＴ，アスコルビン酸等の酸化防止剤、安息香酸ナトリウム、サリチル酸ナトリウム、ソルビン酸、ソルビン酸カリウム、デヒドロ酢酸ナトリウム等の保存安定化剤、安息香酸デナトニウム、トウガラシ末等の誤食防止剤、色素等を適宜添加してもよいことは勿論である。 The ants control agent of the present invention further comprises a bait base (c) to constitute a bait. Such base materials include wheat flour, rice flour, corn flour, grain flour such as ground flour, sugar, sugar sugar, sugar brown, sugars such as sucrose, granulated sugar, clays (kaolin, bentonites Etc., powders of mineral substances such as talcs, sorbitan fatty acid esters, sucrose fatty acid esters, surfactants such as polyoxyethylene hydrogenated castor oil, casein, gelatin, carboxymethyl cellulose (CMC), polyvinyl alcohol, polyacrylic acid There may be mentioned fixing agents such as sodium, gum arabic and xanthan gum, binders, thickeners and dispersants. In addition, BHT, an antioxidant such as ascorbic acid, sodium benzoate, sodium salicylate, sodium sorbate, potassium sorbate, sodium storage stabilizer such as sodium dehydroacetate, as long as the purpose of the present invention is not impaired. It is a matter of course that an inhibitor against misfeeding such as denatonium benzoate and powdered red pepper, a pigment and the like may be added as appropriate.
本発明のアリ類防除剤は、構成成分の各々を混合、必要により水を加えて、粉末状、顆粒状、塊状ベイト剤に成形される。その平均粒径は、採餌アリが巣に持ち帰りやすいように０．０２〜３．０ｍｍに設定する必要があるが、採餌アリがより効率的に運搬できるとともに、アリ類防除剤を施用する際の作業性をも考慮すると、平均粒径が０．５〜２．０ｍｍ程度の顆粒剤が好ましい。 The ants control agent of the present invention is formed into a powdery, granular or massive bait agent by mixing each of the components and adding water as required. The average particle size needs to be set to 0.02 to 3.0 mm so that feeding ants can be easily brought back to the nest, but feeding ants can be transported more efficiently while feeding ants are applied more efficiently. Granules having an average particle diameter of about 0.5 to 2.0 mm are preferable in consideration of workability in the process.
こうして得られた本発明のアリ類防除剤は、アリの巣の存在が発見された付近一帯に１ｍ2あたり５〜３０ｇ程度散布することによって、クロヤマアリ、アミメアリ、トビイロケアリ、トビイロシワアリ、ルリアリ、クロオオアリ、イエヒメアリ、アルゼンチンアリ、ヒアリ、カミアリ等の広範囲なアリ類に対して実用的な防除効果を示すが、従来のアリ類防除剤では防除困難なヒアリやカミアリに対して特に有用性が高いものである。 The thus obtained ant control agent of the present invention is dispersed by about 5 to 30 g per 1 m 2 in the vicinity where the existence of an ant nest is found. It exhibits a practical control effect against a wide range of ants such as Argentine ants, fire ants, and worms, but it is particularly useful for fire ants and chamants that are difficult to control with conventional ants.
次に具体的な実施例に基づき、本発明のアリ類防除剤について更に詳細に説明する。 Next, based on specific examples, the ants control agent of the present invention will be described in more detail.
＜実施例１＞
遅効性のアリ類防除成分（ａ）としてのシラフルオフェンを１．０質量％と、誘引もしくは摂食刺激成分（ｂ）のうちの液状もしくはペースト状成分（ｂ−１）としての大豆油を１．５質量％及び蜂蜜を２．５質量％と、固形状成分（ｂ−２）としての乾燥アカムシ粉を４０質量％とに、ベイト剤基材（ｃ）としてのきな粉を３２質量％及び三温糖を２０質量％と、固着剤としてのカルボキシメチルセルロース（ＣＭＣ）を２．０質量％と、更に保存安定化剤としてのソルビン酸カリウムを１．０質量％加えて均一混合した。これらに水を加えて混練後、平均粒径が２．０ｍｍである顆粒状の本発明のアリ類防除剤（約３ｍｇ／個）を得た。なお、この製剤の（ｂ−１）／（ｂ−２）比率は１０であった。
Example 1
1.0% by mass of silafluofen as a late-acting ant-controlling ingredient (a) and soybean oil as a liquid or pasty component (b-1) of the attraction or feeding stimulation component (b) 5% by mass and 2.5% by mass of honey, and 40% by mass of dry akamushi powder as the solid component (b-2), 32% by mass and 3% of the basic powder as the bait base material (c) 20% by mass of sugar, 2.0% by mass of carboxymethylcellulose (CMC) as a fixing agent, and 1.0% by mass of potassium sorbate as a storage stabilizer were further added and uniformly mixed. Water was added to these, and after kneading, a granular form of the ants controlling agent of the present invention (about 3 mg / piece) having an average particle diameter of 2.0 mm was obtained. In addition, the (b-1) / (b-2) ratio of this preparation was 10.
発見されたヒアリの巣の周囲一帯に、このアリ類防除剤を１ｍ2あたり２０ｇ散布したところ、３０分後あたりから採餌アリがベイト剤を巣に持ち運び始め、１日後には殆どがなくなった。その後、２週間後にかけて巣に出入りする採餌アリを見かけなくなり、巣を掘り返して調査した結果、女王アリを含め無数の働きアリの死亡が確認された。すなわち、本発明のアリ類防除剤が、採餌アリに対して高い運搬効率を有し、更に、巣内の働きアリによるシラフルオフェンの巣内コロニー全体への伝播効率を高めた結果、ヒアリの巣に壊滅的な効果を与えるに至ったのであり、本発明のアリ類防除剤の優れた実用性と有用性が実証された。 When 20 g of this ant control agent was sprayed per 1 m 2 around the found nest of the fire ants, the feeding ants began to carry the bait to the nest around 30 minutes and almost disappeared after 1 day . After that, two weeks later, they ceased to see foraging ants entering and leaving the nest, and as a result of digging and examining the nest, it was confirmed that countless worker ants including the queen ants died. That is, as the ants control agent of the present invention has a high delivery efficiency for feeding ants, and further increases the efficiency of transmission of silafluophene to whole colonies in the nest by worker ants in the nest, the nest of the fire ants Thus, the excellent practicality and usefulness of the ants controlling agent of the present invention have been demonstrated.
＜実施例２〜１２、比較例１〜１０＞
実施例１に準じて表１に示す実施例２〜１２の各種アリ類防除剤を調製した。なお、他成分としては、実施例７の粉剤タイプ以外は固着剤としてのＣＭＣを２．０質量％と保存安定化剤としてのソルビン酸カリウムを１．０質量％配合し、実施例７の粉剤タイプはソルビン酸カリウム１．０質量％のみを添加した。これらの各種アリ類防除剤につき、下記に示す（１）ベイト剤の運搬性試験及び（２）アリ類防除成分の伝播効率性試験を行った。また、比較のため、表１に示す比較例１〜１０の各種アリ類防除剤についても、実施例と同様の試験を行った。
Examples 2 to 12 and Comparative Examples 1 to 10
The various ants control agents of Examples 2 to 12 shown in Table 1 were prepared according to Example 1. As other components, 2.0 mass% of CMC as a fixing agent and 1.0 mass% of potassium sorbate as a storage stabilizer are blended, except for the powder type of Example 7, and the powder of Example 7 As for type, only 1.0% by mass of potassium sorbate was added. About these various ants control agents, the transportability test of (1) bait agent shown below and the propagation efficiency test of the (2) ants control component were done. Moreover, the test similar to an Example was done also about the various ants control agent of Comparative Examples 1-10 shown in Table 1 for a comparison.
（１）ベイト剤の運搬性試験
各供試アリ類防除剤２０個を直径７ｃｍの濾紙上に載せ、クロヤマアリ、アルゼンチンアリ又はヒアリの各巣から２０ｃｍ離れた箇所に置いた。アリが全てのベイト剤を運搬するのに要した時間（分）を記録した。試験はアリの巣及びベイト剤の置き場所を無作為に変えて４回反復し、その平均運搬時間（分）を求めた。結果を表２に示す。
(1) Transportability test of bait agent Twenty test ants were placed on a filter paper of 7 cm in diameter, and placed at a distance of 20 cm from each nest of black ants, Argentine ants or fire ants. The time (minutes) taken by the ants to transport all bait was recorded. The test was repeated four times, with the ant nest and bait placement randomly changed, and the average transport time (minutes) was determined. The results are shown in Table 2.
（２）アリ類防除成分の伝播効率性試験
プラスチック製容器（縦５０ｃｍ、横７０ｃｍ、高さ２０ｃｍ）の中に、石膏を敷いたアクリル製シェルター（縦１０ｃｍ、横２０ｃｍ、高さ５ｃｍの直方体状ボックスでその４側面にそれぞれ直径１ｃｍの孔を設置）を１個置いたものをいくつか準備した。クロオオアリ、トビイロシワアリ及びヒアリの各巣から働きアリを採取し、それぞれ約５０匹を前述の容器に移し馴化させた。容器あたりのアリ類防除成分の合計量が約１ｍｇになるように所定数の供試各アリ類防除剤を容器に入れた。２時間後、各ベイト剤が食餌され尽くされたのを確認し、それぞれの容器に同種のアリを新たに１５０匹追加した。この処理から３日後、５日後、及び７日後に供試アリ合計２００匹の死虫率（％）を求め、アリ類防除成分の伝播効率を評価した。なお、アリ類防除成分の種類や特性によってアリ類に対する殺虫効力の発現に差があるため、伝播効率の評価は供試した各アリ類防除成分ごとに行った。結果を表３に示す。
(2) Propagation efficiency test of ants control ingredient Acrylic shelter (10 cm long, 20 cm wide, 5 cm high) with plaster placed in a plastic container (50 cm long, 70 cm wide, 20 cm high) Several boxes (one with a diameter of 1 cm) were placed on the four sides of the box. The worker ants were collected from each nest of black ants, black-tailed ants and fire ants, and about 50 animals were transferred to the above-mentioned container and allowed to acclimate. A predetermined number of test ants were placed in a container such that the total amount of ants controlling components per container was about 1 mg. After 2 hours, it was confirmed that each bait had been consumed, and 150 additional similar ants were added to each container. The mortality rate (%) of a total of 200 test ants was determined three, five, and seven days after this treatment, and the transmission efficiency of the ants was evaluated. In addition, since there is a difference in the expression of the insecticidal efficacy against ants according to the type and characteristics of the ants controlling component, the evaluation of the transmission efficiency was performed for each ants controlling component tested. The results are shown in Table 3.
試験の結果、本発明のアリ類防除剤、即ち、アリ類に対する誘引もしくは摂食刺激成分（ｂ）は、ベイト剤全体量に対して１．０〜２０質量％の液状もしくはペースト状成分（ｂ−１）と、ベイト剤全体量に対して４．０〜５０質量％の固形状成分（ｂ−２）とで構成され、その（ｂ−１）／（ｂ−２）比率は１／２〜１／４０であり、しかも、前記ベイト剤の平均粒径を０．０２〜３．０ｍｍとなしたベイト剤は、いずれのアリ種に対しても比較例のベイト剤より平均運搬時間が短く、高い運搬効率を示した。特に、ヒアリに対しては、比較例で見られるように、一般にアルゼンチンアリに対する場合より平均運搬時間が長くなる傾向があるにも関わらず、実施例のベイト剤はアルゼンチンアリに対するのとほぼ同等の平均運搬時間を示し、実用性ならびに有用性の高いことが実証された。
なお、液状もしくはペースト状成分（ｂ−１）としては、植物油と糖蜜成分の併用が好ましかった。
As a result of the test, the ants controlling agent of the present invention, that is, the attraction or feeding stimulation component (b) to ants, is 1.0 to 20% by mass of a liquid or pasty component (b -1) and the solid component (b-2) of 4.0 to 50% by mass with respect to the total amount of bait, and the ratio (b-1) / (b-2) is 1/2 In addition, the bait agent having an average particle size of 0.02 to 3.0 mm and having an average particle diameter of 0.02 to 3.0 mm is shorter in average conveyance time than that of the comparative example for any ant species. , Showed high transport efficiency. In particular, for fire ants, as seen in the comparative example, although the average transport time generally tends to be longer than that for Argentine ants, the bait of the example is almost equivalent to that for Argentine ants The average delivery time was shown, and it was proved to be highly practical as well as useful.
In addition, as liquid or paste-like component (b-1), combined use of a vegetable oil and a molasses component was preferable.
一方、比較例１に示すように、速効性のピレスロイド系殺虫成分であるシペルメトリンを用いた場合、採餌アリに対する速やかな殺虫作用が警報フェロモンの放出を伴うなどの理由からアリが離散してしまい、全てのベイト剤が運搬されるに至らなかった。
また、比較例２及び３に示す如く、誘引もしくは摂食刺激成分（ｂ）は、液状もしくはペースト状成分（ｂ−１）と固形状成分（ｂ−２）で構成されることが必須であり、平均粒径が３．０ｍｍを超える比較例６は不適であることも確認された。なお、平均粒径が０．２ｍｍ未満の粉剤タイプについては、液状もしくはペースト状成分（ｂ−１）の配合量を高めるとベタツキ等の製剤上の問題を生じやすい傾向が認められた。
On the other hand, as shown in Comparative Example 1, when cypermethrin, which is a rapid-acting pyrethroid-type insecticidal component, is used, the ants are separated because the rapid insecticidal action against the feeding ants is accompanied by the release of the alarm pheromone. As a result, not all bait was delivered.
Further, as shown in Comparative Examples 2 and 3, it is essential that the attraction or feeding stimulation component (b) is composed of a liquid or paste-like component (b-1) and a solid-like component (b-2). It was also confirmed that Comparative Example 6 having an average particle diameter of more than 3.0 mm was unsuitable. In addition, about the powder agent type whose average particle diameter is less than 0.2 mm, when the compounding quantity of liquid or paste-like component (b-1) was increased, the tendency for it to be easy to produce formulation problems, such as stickiness, was recognized.
試験の結果、本発明のアリ類防除剤、即ち、即ち、アリ類に対する誘引もしくは摂食刺激成分（ｂ）は、ベイト剤全体量に対して１．０〜２０質量％の液状もしくはペースト状成分（ｂ−１）と、ベイト剤全体量に対して４．０〜５０質量％の固形状成分（ｂ−２）とで構成され、その（ｂ−１）／（ｂ−２）比率は１／２〜１／４０であり、しかも、前記ベイト剤の平均粒径を０．０２〜３．０ｍｍとなしたベイト剤は、いずれのアリ種に対しても高い死虫率を示し、アリ類防除成分の栄養交換行動が効率的に行われたものと推察された。
なお、実施例における液状もしくはペースト状成分（ｂ−１）としては、植物油と糖蜜成分の併用が好ましく、その伝播効率は、クロオオアリやトビイロシワアリに対するよりヒアリに対して高くなる傾向が認められた。また、アリ類防除成分としてピリプロキシフェンを用いたベイト剤（実施例１１及び１２、比較例９及び１０）では殺虫効力の発現が遅かったが、これはピリプロキシフェンの作用機作に基づくものと考えられる。
As a result of the test, the ants controlling agent of the present invention, that is, the attraction or feeding stimulant component (b) to the ants, is 1.0-20 mass% of liquid or pasty component with respect to the total amount of bait (B-1) and a solid component (b-2) of 4.0 to 50% by mass with respect to the total amount of bait, and the ratio (b-1) / (b-2) is 1 The bait agent which has a mean particle size of 0.02 to 3.0 mm and has a high mortality rate against any ant species, and an ant It was inferred that nutrient exchange behavior of the control components was efficiently performed.
In addition, as liquid or paste-like component (b-1) in an Example, combined use of a vegetable oil and a molasses component is preferable, and the tendency for the propagation efficiency to be higher with respect to a firefly than the direction with respect to the black ant or the black-necked weir was recognized. In addition, the bait preparation using pyriproxyfen as an ant control component (Examples 11 and 12 and Comparative Examples 9 and 10) showed a delayed onset of insecticidal efficacy, which is based on the mechanism of action of pyriproxyfen it is conceivable that.
一方、比較例１に示すように、速効性のピレスロイド系殺虫成分であるシペルメトリンを用いた場合、食餌したアリが初期の段階で死んでしまうため栄養交換行動がスムーズに行われず、全体の死虫率が伸びなかった可能性が考えられる。
また、比較例２及び３に示す如く、誘引もしくは摂食刺激成分（ｂ）は、液状もしくはペースト状成分（ｂ−１）と固形状成分（ｂ−２）で構成されることが必須であり、平均粒径が３．０ｍｍを超える比較例６は不適であることも確認された。
On the other hand, as shown in Comparative Example 1, when cypermethrin, which is a rapid-acting pyrethroid insecticidal component, is used, the fed ants die at an early stage, so nutrient exchange behavior is not smoothly performed, and the entire death occurs. It is possible that the insect rate did not increase.
Further, as shown in Comparative Examples 2 and 3, it is essential that the attraction or feeding stimulation component (b) is composed of a liquid or paste-like component (b-1) and a solid-like component (b-2). It was also confirmed that Comparative Example 6 having an average particle diameter of more than 3.0 mm was unsuitable.
本発明のアリ類防除剤は、アリ用だけでなく広範な害虫駆除を目的として利用することが可能である。 The ants control agent of the present invention can be used not only for ants but also for a broad range of pest control.
