【発明の属する技術分野】
本発明は、フラッシングアウト増強剤、該増強剤とピレスロイド系殺虫剤を含有した殺虫剤組成物に関する。
【0002】
【従来技術】
ゴキブリのようなふだんは人の目につかない物陰に潜んでいる害虫を駆除する場合、エアゾール剤を噴霧したり、燻蒸剤で燻したりすることが行われている。これらの製剤にピレスロイド系殺虫剤が配合されている場合には、ゴキブリが物陰から飛び出してくる現象(フラッシングアウト)がみられることが知られている。そしてこの現象によりゴキブリが殺虫剤と接触する機会が増えて殺虫効果を高めることができる。そのためフラッシングアウトは、物陰の多い居室、厨房設備、食品倉庫等でゴキブリを駆除する際に、重要な作用の一つとして認識されている。
【0003】
このような理由からピレスロイド系殺虫剤は多用され、その結果としてピレスロイド系殺虫剤に対して強い抵抗力をもつゴキブリが出現している。このようなゴキブリにおいては、ピレスロイド系殺虫剤による殺虫効果の低減に加えてフラッシングアウトもみられなくなりゴキブリを駆除するのが困難となっている。
【0004】
【発明が解決しようとする課題】
本発明は、上記のような状況に鑑みてなされたものであり、ゴキブリを効率的に駆除するための手段について検討を進めるなかで、ピレスロイド系殺虫剤に抵抗力をもつゴキブリに対しても、フラッシングアウトを増強させれば殺虫効果を高めることができるとの考えに至った。
ところが従来においては、このような技術思想について検討されたものはなく、その具体的な手段については知られていない。そこで本発明の課題は、この考えに基づいてフラッシングアウトを増強し殺虫効力を高めるための有効な手段を確立し、ゴキブリを効率的に駆除するための手段を提供することである。

[0002]
[Prior art]
Ordinarily, cockroaches, such as cockroaches, are sprayed with aerosols or fumigated with a fumigant in order to get rid of the pests lurking in the shade. It is known that when a pyrethroid insecticide is added to these preparations, a phenomenon in which cockroaches jump out of the shadow (flushing out) is observed. This phenomenon increases the chances of cockroaches coming into contact with insecticides and enhances the insecticidal effect. Therefore, flushing out is recognized as one of the important effects when cockroaches are extinguished in rooms with many shadows, kitchen facilities, food warehouses, and the like.
[0003]
For these reasons, pyrethroid insecticides are frequently used, and as a result, cockroaches with strong resistance to pyrethroid insecticides have emerged.

[0014]
・ Flushing-out, insecticidal efficacy test A 10 g granule (diameter 3 mm × length 5 mm) having the composition shown in Table 1 is manufactured and filled into an inner container, and a hydrothermal exothermic transpiration agent using calcium oxide as the exothermic agent. Set. The transpiration agent is placed in the center of the floor of the test room (32 m 3 ) set to the arousal condition once / hour, and a triangular shelter (side 3 cm, height 15 cm) is placed at two opposite corners of the test room. Ten German cockroaches were placed inside.
The transpiration agent is evaporated and exposed for 60 minutes, and the FT50 (the time required for 50% of the cockroaches to jump out of the shelter) and the flushing-out rate (the ratio of cockroaches that jump out of the shelter by the end of the test) The effect was confirmed. Thereafter, cockroaches were placed in a clean container and placed in a room at 25 ° C., and the lethality after 24 hours was determined. In the test, adult German cockroaches having 9 times the resistance to pyrethroid insecticide (permethrin) were used. The test was performed twice, and the average value is shown in Table 2 as a result.
