Description
本発明は、殺虫原体を使用せずともコバエ類の防除に有用な組成物、およびこれを用いたスプレー製品およびコバエ類防除方法に関するものである。 The present invention relates to a composition useful for controlling fly flies without using a pesticide substance, and a spray product and a fly fly control method using the same.
ショウジョウバエ等のコバエ類は、ゴミや腐敗した食物から度々発生して人に不快感を与えることから防除の対象とされてきた。一般的には、ハエ、カ用のエアゾール剤を噴霧したり、燻煙剤を処理したりする等が行われている(例えば、非特許文献1参照。)。ところがコバエ類にはイエバエ等と比べて、十分な防除効果を得られないことがあった。これはコバエ類が早く世代交代をし、殺虫剤に対する抵抗性を発達させやすいためと考えられる。そのため、現在もコバエの防除に用いる新規な活性化合物の検討はなされており、その1つとしてカラン−3,4−ジオールが知られている(例えば、特許文献1参照。)。ただし前記の活性化合物は浄化槽等へのコバエの侵入を抑制することで防除するものであって、コバエに殺虫効果を奏することは示されていない。
コバエ用の殺虫剤として検討された製剤としては、殺虫成分と炭化水素類などを含有したエアゾール剤が挙げられる(特許文献2参照)が、ピレスロイド系などの殺虫原体や可燃性の炭化水素類を含んでいることで、使用者が安心感を十分には得られないものであった。また、コバエ類の防除用として殺虫原体以外の化合物はほとんど知られていない。
Fruit flies such as Drosophila have been targeted for control because they are frequently generated from garbage and spoiled foods, causing discomfort to humans. In general, aerosols for flies and mosquitoes are sprayed, smoke agents are treated, and the like (for example, see Non-Patent Document 1). However, the fly flies may not be able to obtain a sufficient control effect compared to the house flies. This is thought to be due to the fact that the fly flies are easy to change generations and develop resistance to insecticides. For this reason, studies on novel active compounds for use in controlling fly flies are still underway, and one of these is known as caran-3,4-diol (see, for example, Patent Document 1). However, the active compound is controlled by suppressing the invasion of the fly to a septic tank or the like, and it has not been shown to exert an insecticidal effect on the fly.
Formulations that have been examined as insecticides for fly flies include aerosols containing insecticide components and hydrocarbons (see Patent Document 2), but pyrethroids and other insecticides and flammable hydrocarbons. Including this, the user cannot obtain a sufficient sense of security. In addition, few compounds other than the insecticidal substance are known for controlling fly flies.
そこで本願発明は、殺虫原体や可燃性ガスを必要とせずともコバエ類に対して優れた防除効果を奏することができ、かつ使用者への安心感を与え得る新規なコバエ類防除用組成物および製品を提供することを目的とする。 Therefore, the present invention is a novel composition for controlling fly flies that can exert an excellent control effect on fly flies without requiring an insecticidal active ingredient or a flammable gas, and can give a sense of security to the user. And to provide products.

(2)前記コバエ類防除用液体組成物が植物精油及び還元澱粉糖化物のうち少なくとも一方をコバエ類防除の有効成分としてさらに含有することを特徴とする上記(1)に記載のコバエ類防除用スプレー製品。
(3)噴霧粒子の体積平均粒子径d50が70〜160μmであることを特徴とする上記(1)または(2)に記載のコバエ類防除用スプレー製品。
As a result of intensive studies to solve the above-mentioned problems, the present inventors have found that a composition containing ethanol and a surfactant as active ingredients has an excellent control effect against fruit flies, and has led to the present invention. That is, the present invention is achieved by the following means.

(試験例1)
表1に示した組成物を調製し、各々150mLを容積300mLのエアゾール容器に充填し、窒素ガスを充填して内圧0.7MPaの検体とした。
(Test Example 1)
The compositions shown in Table 1 were prepared, 150 mL each was filled into a 300 mL volume aerosol container, and nitrogen gas was charged into a specimen having an internal pressure of 0.7 MPa.
8畳相当のチャンバー(3.6m×3.6m×2.7m)内に、図1に示すような試験系を設置した。チャンバーの床面からの高さ150cmに、供試虫(キイロショウジョウバエ成虫、雄雌混合)10頭を入れたケージ(φ13cm×L15cm)を吊るし、検体を15cmの距離から2秒間(約4.8g)水平噴射して、噴射直後から1分後に供試虫の状態を観察し、ノックダウン(以後KD)率と瀕死率を算出した。試験は3回行い、その平均結果を表2に示す。 A test system as shown in FIG. 1 was installed in a chamber (3.6 m × 3.6 m × 2.7 m) corresponding to 8 tatami mats. A cage (φ13 cm × L15 cm) containing 10 test insects (mixed Drosophila melanogaster, male and female) was hung at a height of 150 cm from the floor of the chamber, and the specimen was suspended from a distance of 15 cm for about 2 seconds (about 4.8 g). ) After horizontal injection, the state of the test insect was observed 1 minute after the injection, and the knockdown (hereinafter referred to as KD) rate and the mortality rate were calculated. The test was performed three times, and the average results are shown in Table 2.
エタノール濃度が低下するほど効力が低下する結果となった。エタノール95重量%と60重量%での供試虫の瀕死率は同等であり、40重量%以下では瀕死率は極端に低下した。 As the ethanol concentration decreased, the efficacy decreased. The mortality rate of the test insects at 95% by weight and 60% by weight of ethanol was equivalent, and the mortality rate was drastically decreased at 40% by weight or less.
(試験例2)
参考例4の検体に、噴口径の異なるボタンを装着して試験に用いた。

The sample of Reference Example 4 was equipped with buttons having different nozzle diameters and used for the test.
Using a laser light scattering particle size distribution analyzer LDSA-1400A (manufactured by Tohnichi Computer Applications Co., Ltd.), the measurement was performed three times, and the average value of the volume average particle diameter d50 was defined as the average particle diameter.
Tests were performed under the same conditions as in Test Example 1 using four types of specimens with different buttons and different spray particle sizes. However, the specimen injection amount was adjusted to about 4.8 g (an amount corresponding to the 2-second injection in Test Example 1), and the test insects that were unable to fly after 1 minute were observed. The test was performed three times, and the average result is shown in Table 3.
平均粒子径が100μmのとき供試虫の100%が飛翔不可能となり、70μm、157μmの場合でも80%以上であった。 When the average particle size was 100 μm, 100% of the test insects could not fly, and even when the particle size was 70 μm and 157 μm, it was 80% or more.

植物精油、エタノールと水との混合液に加え、水もしくは水を含む溶媒に溶解または可溶化しうる界面活性剤を配合することによって、24時間後致死率が高くなることが分かった。 It has been found that the lethality increases after 24 hours by adding a surfactant that can be dissolved or solubilized in water or a solvent containing water in addition to a mixture of plant essential oil and ethanol and water.
(試験例5)
表7に示す実施例4の組成物を試験例1と同様にエアゾール製剤とした検体と、参考例8の組成物をハンドポンプに充填したポンプ製剤を用いて、試験例1と同様の試験を行った。ただし、エアゾールの噴射量は4.8g(2秒間噴射に相当)、ポンプの噴射量は約4.5g(5回プッシュ)に合わせ、試験例3と同様に24時間後の致死率も観察した。試験は3回行い、その平均結果を表8に示す。なお、噴霧粒子の体積平均粒子径d50は約120μmであった。

(試験例6)
表7に示す実施例4の組成物を試験例1と同様にエアゾール製剤とした検体を用い、試験例1と同様の試験系にて試験を行った。ただし、供試虫はイエバエ(雌)20頭とし、検体と供試虫の入ったケージ間の距離を25cmとした。検体を2秒間(約4.8g)、および3秒間(約7.2g)水平噴射して、1分後のKD率と24時間後の致死率を観察した。試験は2回行い、その平均結果を表9に示す。
(Test Example 6)
Tests were carried out in the same test system as in Test Example 1, using a specimen prepared from the composition of Example 4 shown in Table 7 as an aerosol preparation in the same manner as in Test Example 1. However, the number of test insects was 20 house flies (female), and the distance between the specimen and the cage containing the test insects was 25 cm.
