Definitions
- the present invention relates to a spider mite repellent.
- Spider mites have eight legs and are classified as spiders. Spider mites live primarily on the leaves of plants, are herbivorous, and suck their contents from the mesophyll tissue. Sucking scars are formed on the leaves after sucking, and if the damage becomes large, the leaves will die. Spider mites have a high ability to walk, move from plant to plant, and suck mesophyll tissue. Therefore, the damage caused by spider mites to crops, fruit vegetables, fruit trees, etc. is enormous. Chemical control, biological control, physical control, etc. have been proposed as means for controlling such spider mites, and organic phosphorus agents, carbamate agents, synthetic pyrethroid agents, etc. are used as agents.
- Patent Document 1 describes the use of agents containing glycerin fatty acid esters, sorbitan fatty acid esters, sucrose fatty acid esters, etc. as active ingredients against winged pests such as whiteflies. is proposed.
- spider mites do not have the ability to fly. To go. In the case of winged pests, feeding damage can be reduced if it is possible to suppress their flying to target plants.

なお、各試験で使用した油脂に含まれる代表的な脂肪酸の組成は以下の通りである。
・ハイオレインナタネ部分水添油(アクターLO-1、理研ビタミン(株)社製)
・オリーブ油(エクストラバージンオリーブオイル)…オレイン酸約80質量%、リノール酸約5質量%、リノレン酸約1質量%、ステアリン酸約3質量%、パルミチン酸約9質量%
・オレインリッチひまわり油…オレイン酸約84質量%、リノール酸約7~8質量%、リノレン酸約0.1質量%、ステアリン酸約3質量%、パルミチン酸約4質量%
・オレインリッチキャノーラ油…オレイン酸約76質量%、リノール酸約14質量%、リノレン酸約2質量%、ステアリン酸約2質量%、パルミチン酸約3~4質量%

ハイオレインナタネ部分水添油(LO-1)(商品名:アクターLO-1、理研ビタミン(株)社製)と助剤Kとを100:3の質量比で混合し、試験1で使用する組成物を調製した。助剤Kの組成は、以下の通りである。
助剤K…1-プロピルアルコール/CA-42/DO-100=1.5/1.0/0.5(質量比)。
CA-42…ポリオキシエチレンキャスターオイル(エチレンの重合度は42、東邦化学製)。
DO-100…ポエムDO-100V(ジグリセリンモノオレエート、理研ビタミン(株)社製)。
LO-1以外の油脂がハダニの移動に及ぼす影響を調べた。試験に用いた油脂は、表2に示す通りである。表2に示す各油脂を試験1と同様の比率で助剤Kと混合し、水で100倍に希釈した薬液をこの試験に用いた。試験1と同様の方法により、ハダニが生育していないインゲンに移動したハダニの頭数を調べた。評価基準は、以下のとおりである。
「-」:移動したハダニ数0頭
「+」:移動したハダニ数1~10頭未満
「++」:移動したハダニ数10~50頭未満
「+++」:移動したハダニ数50頭以上
その結果を表2に示す。
試験2の結果、LO-1以外にオリーブ油を用いた場合にも、ハダニの移動を強く抑制できることが分かった。他方、LO-1やオリーブ油と同様に構成脂肪酸としてオレイン酸を多く含む織レインリッチひまわり油、オレインリッチキャノーラ油、オレインリッチ紅花油を用いた場合には、ハダニの移動を抑えることが出来なかった。
ハダニの移動に及ぼすLO-1の影響を更に調査した。この試験では、試験1で調製された組成物を水で200倍に希釈した薬液を用いた。
10個のインゲン苗を用意し、これを5個ずつに分けた(処理区の5個の苗、無処理区の5個の苗)。処理区の5個のインゲン苗を水を張った水槽内にほぼ横一列に並べ、ハダニが苗間を移動できるよう、1個目の苗の双葉の右側の葉を2個目の苗の左側の葉につないだ。2個目の苗の右側の葉は、3個目の苗の左側の葉につないだ。これを繰り返し、5個の苗をほぼ横一列につないだ(1個目の苗の左側の葉から5個目の苗の右側の葉の順に、計10枚の葉をそれぞれ1~10枚目の葉と呼ぶ)。無処理区の5個のインゲン苗についても同様につなぎ、処理区の5個の苗と無処理区の5個の苗とが接触しないようにして、処理区の5個の苗と無処理区の5個の苗を「V」の字を右に90度傾けた形に配置した(処理区の5個の苗がVの字の一方の直線を形成し、無処理区の5個の苗がVの字のもう一方の直線を形成した)。最後に、ハダニの生育している苗の葉をVの字の2本の直線が重なる部位に配置して、処理区の5個の苗及び無処理区の5個の苗のそれぞれの1個目の苗の左側の葉につないだ。ハダニが、それぞれの1個目の苗の左側の葉(1枚目の葉)に移動したことを確認した。
上記で調製した薬液を、処理区の5個の苗の2個目以降の苗の葉(3枚目以降の葉)に散布した。無処理区の5個の苗については薬液処理を行わなかった。散布から6日後にハダニの移動を調べたところ、無処理区ではハダニが10枚目の葉に到達していたが、処理区ではハダニは3枚目の葉に到達したものの、4枚目以降の葉には移動していなかった。
散布から8日後、処理区の苗のうちハダニが移動していない4枚目以降の葉に、再度薬液を散布した。2度目の散布から6日後にハダニの移動を調べたところ、無処理区ではハダニが10枚目の葉に到達していたが、処理区ではハダニは4枚目の葉には移動していなかった。
試験4では、油脂を溶解するアルコールの種類を変えて、有効成分によるハダニ忌避効果への影響を検討した。
薬液1は、LO-1の10gに助剤Kを0.3g添加し、よく攪拌してから250mg/100mLとなるように水で希釈したものを用いた(希釈率:400倍)。
薬液2は、LO-1の10gに助剤Kではなく助剤Eを0.3g添加し、よく攪拌してから250mg/100mLとなるように水で希釈したものを用いた(希釈率:400倍)。
薬液3~4は、LO-1をオリーブポマスオイル又はオリーブオイルに変更した以外は薬液2と同様にして調製したものを用いた(希釈率:400倍)。
助剤Kと助剤Eの組成は以下の通りであり、助剤Eは1-プロピルアルコールに代えてエタノールが含まれている以外は、助剤Kと同組成である。
助剤K…1-プロピルアルコール/CA-42/DO-100=1.5/1.0/0.5(質量比)。
助剤E…エタノール/CA-42/DO-100=1.5/1.0/0.5(質量比)。
上記で調製した各薬液を、インゲン子葉の一方に散布した。散布しなかった方の子葉をハダニの発生しているインゲン葉につなぎ、栽培を続けた。3日後、薬液を散布した葉に移動してきたハダニによって生じた食害痕を調べた。評価基準は、以下のとおりである。
「-」:食害痕なし、「±」:食害痕1~5個、「+」:食害痕6~15個、「++」:食害痕16~30個、「+++」:食害痕31~50個、「++++」:食害痕51~100個、「+++++」:食害痕100個超過
その結果を表3に示す。
試験4の結果、油脂とエタノールとを組み合わせると、油脂と1-プロパノールとを組み合わせた場合よりも食害痕が少なく、低濃度であってもハダニ忌避効果が高いことが分かった。また、オリーブポマスオイルが、オリーブオイルやLO-1と同様にハダニに対して忌避効果を有することが分かった。
試験5では、助剤K、助剤Eがハダニに対する忌避効果を有するかどうかを検討した。
LO-1と助剤Kを100:3の質量比で混合した組成物1gと、助剤K単独の溶液3mgをそれぞれ調製し、これらを100mLの水で希釈した(100倍希釈)。
また、オリーブポマスオイルと助剤Eを100:3の質量比で混合した組成物100mg、助剤E単独の溶液3mgをそれぞれ調製し、これらを100mLの水で希釈した。
得られた各薬液を、インゲン子葉の片側に散布し、風乾後に薬液を散布していない葉をハダニの生育している葉につなげて栽培を続け、散布した葉に移動してきたハダニによる食害痕数を比較した。評価基準は、以下のとおりである。
「-」:食害痕なし、「±」:食害痕1~5個、「+」:食害痕6~15個、「++」:食害痕16~30個、「+++」:食害痕31~50個、「++++」:食害痕51~100個、「+++++」:食害痕100個超過
その結果を表4に示す。
試験5の結果、助剤K、助剤E単独ではハダニによる食害を全く抑制できず、ハダニに対する忌避効果を有さなかった。この結果から、本発明のハダニ忌避効果は、助剤ではなく、上記特定の油脂によってもたらされているものと考えられた。
