Description

【0001】
【発明の属する技術分野】
本発明は香辛料で使われる植物から抽出される成分を利用して昆虫類の退治に使われる防虫剤組成物に関するものであり、より詳細には穀物類の貯蔵時に発生するコメ穀象虫などのような昆虫類を退治するために香辛料成分としてスルファイド成分を含有する植物から抽出される精油成分とから構成される防虫剤組成物に関するものである。
【0002】
【従来の技術】
コメなどのように脱穀及び精米過程を経て米を保存する場合にコメ穀象虫などのような昆虫が棲息する。こういった昆虫の生息を防止するために大型貯蔵施設では薫蒸法、接触殺虫法、密封法、低温貯蔵法、放射線照査法などの多様な方法で処理する方法がとられている。しかし、殺虫剤を使用する場合では殺虫剤の成分が穀物に付着して、食物の調理時に除去が容易でなく、安全性の面で問題を起こしている。また、大部分の処理方法は大規模な貯蔵施設に適用する方法であり、特別の貯蔵施設や技術を必要とする前述の方法では、小規模な保存を行っている家庭に適用するのには問題があった。
【0003】
前記のような問題から、小規模で保存する家庭などで適用するための方法に対する研究が進められてきた。そのうちでも人体に対する毒性がなく、安全性が高い香辛料で使われる植物から抽出される精油成分を利用する方法に対し多くの研究が進められてきた。
【0004】
そうした結果、米国環境保護局では安全性が高い退治剤としてニンニクから抽出されるアリシンと唐辛子から抽出されるカプサイシンが登録されて公開されており、これを活用した日本国特開平第6-38678号ではアリシン成分、カプサイシン成分、セラミック成分、活性炭及びカルシウム成分を混合してコメの品質保存剤として使用する技術が公開されているが、満足できるような忌避効果を得ることが難しかった。
【0005】
したがって、本発明者等はカプサイシンとアリシンの適切な組合によって昆虫類の忌避効果を高めることができる防虫組成物を開発してこれを韓国特許出願第98-9126号で特許出願したことがある。
【0006】
【発明が解決しようとする課題】
しかしながら、前記韓国特許出願第98-9126号によって製造された退治剤の場合にあっても運動能力が少ない害虫や、害虫の幼虫や卵に対する防虫効果は期待することが難しい短所があった。
【0007】
また、防虫組成物として、からしとワサビの抽出物を利用した防虫組成物が市販されており、これらはニンニクと唐辛子を使用した防虫剤より忌避効果が優秀な長所があるが、硫黄成分を含有する化合物の不安定性によって忌避率を持続することが難しい短所があった。
【0008】
本発明者等はこのような問題点を勘案して、人体に無害でありながらコメ穀象虫などのような穀物害虫に対する持続的で優れた忌避及び殺虫効果を有する防虫剤組成物を提供することにある。
【0009】

【0023】
以上のような本発明の課題を解決するための手段と特徴及び長所については、本発明のいくつかの好適な実施例に対する以下の説明で明確にする。
【0024】
【発明の実施の形態】
前記で列挙している各香辛料の忌避効果は、含有する成分によって差がでることが予想される。これを確認するために前記香辛料成分に対するコメ穀象虫の忌避効果を下の実施例によって実験してその忌避率を調べた。
【0025】
(実施例1)
分子構造に硫黄を含有する化合物を有する精油成分及び芳香族化合物を有する精油成分を下記の表1のように選定して抽出物の精油成分に対し20%の酢酸を添加させたものと、無添加のものとを比較する実験を行った。これらの酢酸無添加のものと、酢酸を添加した各精油1gをパルプ紙0.5gに吸着させた後、図1に示したように横33cm、縦23cm、高さ5cmの四角試験容器1の内部両側に直径5.5cmの円形プレート2、2'を各々設置して一側の円形プレート2には精米されたコメ4を20g載置し非防虫処理口とし、他側の円形プレート2'には底面に精油が含沈されているパルプ紙3を設置してその上に20gのコメ4を載置して防虫処理口とする。非防虫処理口及び防虫処理口の円形プレート2、2'の間に50頭のコメ穀象虫を放して置いた。次に、上部を通じて通気ができるようにふたで覆った後2日間放置して、下記の数学式に基づいて忌避率を調べた結果下記の表1の結果を得た。
【数学式1】

【0026】
前記の表1から確認されるように精油成分の分子構造内に硫黄を含有するからし、玉ネギ及びニンニクの場合においては精油成分に対し20%の酢酸を添加させた結果その忌避率が10%以上上昇していることを示しているが、精油成分が芳香族化合物で構成されるティトリ及びシソの場合においてはコメ穀象虫などの忌避率にそれほど変化が無いことがわかる。
【0027】
前記の実施例から得た結果を土にして組成物の安定性に関する実験を下記の実施例2〜9について行った。ワサビ、からしの精油を表2に表示した重量%のように配合した防虫剤組成物を製造し、安定化剤として酢酸、乳酸、蟻酸、クエン酸を表2のように添加して前述の実施例1と同様の方法で試験した。なお、コメ穀象虫の数は各実施例当たり30頭づつにして実験し、その忌避率を表2に表示した。
【表2】

【0028】
表2において、防虫処理口及び非防虫処理口は実験結果によるコメ穀象虫の数を示し、忌避率は前記の数学式1による計算結果である。
【0029】
前記の表2の実施例2ないし実施例6の結果から分かるように、硫黄を含有する香辛料成分のワサビとからしとを配合した防虫剤組成物に酢酸を添加しない実施例2の場合においてはその忌避率が86%に過ぎないが、実施例3〜実施例5の結果から、防虫剤組成物にたいし20%以下の酢酸を添加した場合、忌避率が93%〜98%に増加し、酢酸を30%以上添加した実施例6の場合においては忌避率が84%に落ちることがわかる。
【0030】
また、他の揮発性有機酸を10%ずつ添加した実施例7〜実施例9と実施例2の結果を比較してみると、実施例7〜実施例9の結果は93%以上を示していることから、揮発性有機酸を添加することにより、はるかに高い忌避率をもたらすことが分かった。この場合揮発性有機酸の添加量は、防虫剤組成物にたいし20%以下とすることが有利であることがわかる。
【0031】
本発明を実施例によって詳細に説明したが、本発明は実施例によって限定されず、本発明が属する技術分野において通常の知識を有するものであれば本発明の思想と精神を離れることなく、本発明を修正または変更できるであろう。
【0032】
【発明の効果】
以上詳細に説明したように、香辛料で使われるからしの精油、ワサビの精油、ニンニクの精油、玉ネギの精油などを主成分としてその他の香辛料成分を含有させた忌避性の防虫剤組成物に酢酸、蟻酸、乳酸、フマル酸、コハク酸、リンゴ酸、及びクエン酸から選ばれる1以上の有機酸を添加することにより、コメ穀象虫に対する忌避率を格段に向上させることができる。
【0033】
また、人体に無害であり、手軽に使用できることから、小規模な貯蔵を行う一般家庭でも使用できる。このため、広く、穀物の貯蔵を阻害する昆虫類、特に主食の米の害虫である穀象虫の忌避剤として使用することができる。

[0023]
Means, features, and advantages for solving the above-described problems of the present invention will be clarified in the following description of some preferred embodiments of the present invention.
[0024]
DETAILED DESCRIPTION OF THE INVENTION
It is expected that the repellent effect of each spice listed above will vary depending on the components it contains. In order to confirm this, the repellent effect of rice cereals on the spice ingredients was tested according to the following examples to examine the repellent rate.
[0025]
(Example 1)
The essential oil component having a compound containing sulfur in the molecular structure and the essential oil component having an aromatic compound are selected as shown in Table 1 below, and 20% acetic acid is added to the essential oil component of the extract. Experiments were performed comparing the additions. These acetic acid-free ones and acetic acid-added 1 g of each essential oil were adsorbed on 0.5 g of pulp paper, and then, as shown in FIG. Circular plates 2 and 2 ′ having a diameter of 5.5 cm are installed on both sides of the inside, and 20 g of polished rice 4 is placed on one side of the circular plate 2 to form a non-insect-proofing mouth, and the other side circular plate 2 ′. The pulp paper 3 having essential oil impregnated on the bottom is placed, and 20 g of rice 4 is placed thereon to form an insecticidal treatment port. Between the non-insect-proof mouth and the round plates 2, 2 'of the insect-proof mouth, 50 rice elephants were left free. Next, after covering with a lid so as to allow ventilation through the upper part, it was allowed to stand for 2 days, and the repelling rate was examined based on the following mathematical formula. The results shown in Table 1 below were obtained.
[Formula 1]
Figure 0004274644
In the above formula, A is the number of rice cereals found from the round plate of the non-insect-proofing mouth, and B means the number of rice cereals found from the round plate of the insect-proofing mouth.
[Table 1]
Figure 0004274644
[0026]
As confirmed from Table 1 above, sulfur is contained in the molecular structure of the essential oil component. In the case of onion and garlic, 20% acetic acid is added to the essential oil component, resulting in a repelling rate of 10 In the case of Titri and Perilla whose essential oil components are composed of aromatic compounds, it can be seen that there is no significant change in the repellent rate of rice cereals and the like.
[0027]
Experiments on the stability of the composition were conducted for the following Examples 2 to 9, using the results obtained from the above Examples as soil. An insect repellent composition containing wasabi and mustard essential oil as shown in Table 2 in the weight% is manufactured, and acetic acid, lactic acid, formic acid and citric acid are added as shown in Table 2 as stabilizers. The test was performed in the same manner as in Example 1. In addition, the number of rice grain elephants was tested at 30 per each example, and the repelling rate was displayed in Table 2.
[Table 2]
Figure 0004274644
[0028]
In Table 2, the insect-repellent treatment port and the non-insect-repellent treatment port indicate the number of rice cereals according to the experimental results, and the repelling rate is the calculation result by the mathematical formula 1.
[0029]
As can be seen from the results of Examples 2 to 6 in Table 2 above, in the case of Example 2 in which acetic acid is not added to the insecticide composition containing wasabi and mustard as the spice ingredients containing sulfur. Although the repellent rate is only 86%, from the results of Examples 3 to 5, when 20% or less of acetic acid is added to the insect repellent composition, the repellent rate increases to 93% to 98%. In the case of Example 6 where acetic acid was added in an amount of 30% or more, it was found that the repelling rate dropped to 84%.
[0030]
Further, comparing the results of Example 7 to Example 9 and Example 2 in which other volatile organic acids were added 10% at a time, the results of Example 7 to Example 9 showed 93% or more. Thus, it was found that adding a volatile organic acid resulted in a much higher repellent rate. In this case, it can be seen that the amount of volatile organic acid added is advantageously 20% or less with respect to the insect repellent composition.
[0031]
Although the present invention has been described in detail with reference to the embodiments, the present invention is not limited to the embodiments, and the present invention can be used without departing from the spirit and spirit of the present invention as long as it has ordinary knowledge in the technical field to which the present invention belongs. The invention could be modified or changed.
[0032]
【The invention's effect】
