【発明の属する技術分野】
本発明は、有効成分としてビストリフルロン(N−(2−クロロ−3,5−ビス−(トリフルオロメチル)フェニル)−N’−(2,6−ジフルオロベンゾイル)ウレア)(以下本化合物という)を用い、アリまたはゴキブリの餌に含有させてなることを特徴とするアリまたはゴキブリ用食毒剤(以下本食毒剤という)、ならびに当該食毒剤を適当な容器(ベイトステーション)に収納し、その容器をゴキブリまたはアリの通り道に設置することを特徴とするアリおよびゴキブリの防除方法に関する。
【0002】
【従来の技術】
アリ類またはゴキブリ類を防除するためには、殺虫剤をこれら昆虫の生息する場所へ散布したり、通り道上に殺虫剤を散布する、または屋外の巣に直接処理する方法が一般的である。一方、近年レスケミカル化の動きや処理の簡便さから食毒剤が好まれる傾向になった。食毒剤の効力を上げるためには如何に多くの殺虫成分をこれら昆虫に食べさせるか、またいかに多くの個体に伝搬させるかにかかっている。このような状況下で、文献1に示すように、ヒドラメチルノン等の殺虫剤がこれら昆虫用の食毒剤として用いられていた。しかしながら、これらの剤は上市されて長い年月が経過しており、食べ飽きや抵抗性などの問題が起こる可能性が指摘されてきた。
また、本化合物は、特許文献1に記載されており、アリまたはゴキブリに有効であることが述べられている。しかしながら、本化合物をアリまたはゴキブリの食毒剤として使用できることについては何ら記載されておらず、また示唆もされてもいない。

The present invention relates to a method for controlling ants and cockroaches, which comprises installing the container on the path of cockroaches or ants.
[0002]
[Prior art]
In order to control ants or cockroaches, it is common to spray insecticides to the places where these insects inhabit, to spray the insecticides on the streets, or to apply them directly to outdoor nests. On the other hand, in recent years, poisons have tended to be preferred due to the movement of less chemicals and the simplicity of treatment. The effectiveness of a poison depends on how many insecticidal ingredients are fed to these insects and how much they are transmitted to many individuals. Under such circumstances, as shown in Reference 1, insecticides such as hydramethylnon have been used as poisons for these insects. However, many years have passed since these drugs were put on the market, and it has been pointed out that problems such as fatigue and resistance may occur.
Further, the present compound is described in Patent Literature 1 and states that it is effective for ants or cockroaches. However, there is no description or suggestion that the present compound can be used as a poison for ants or cockroaches.
