Description

The present invention provides techniques relating to annelid populations and flat animal population protection agents. More specifically, it contains one or more compounds selected from the group consisting of salicylic acid derivatives (2-hydroxyethyl salicylate, methyl salicylate, salicylic acid, etc.) as active ingredients, and in addition, terpenes or vanilloids are included. Annelida populations consisting also be mixture Contact called squamous animal populations control agent provides its use.

Pests such as annelids represented by hills suck blood and cause damage to forest managers working on the devastation of satoyama.
Current control methods include commercially available insect repellent sprays, N, N-diethyl-m-toluamide (DEET), wood vinegar, salt, soap, anionic ring-shaped animal repellents.

However, DEET, which has higher repellent effect and practicality than wood vinegar and salt, is instructed by the American Academy of Pediatrics to extremely reduce the DEET content of insect repellents for children (Non-patent Document 1). Also, if you touch your hands, wash them with soap and water, and you may not be able to touch your skin.

Therefore, wood vinegar and citronella oil are listed as active ingredients for pest repellents that are safer and less environmentally burdensome than the insecticides mentioned above, but a large amount of spraying is required to confirm their repellent effects. (Non-patent document 2).

The present invention is excellent in sustainability and stability, exhibits an excellent control effect, is not limited in use form, has safety (particularly high safety to the human body) as derived from natural products, and has an environmental burden. To provide a control agent for an annelid population and a flat animal population that can be expected to be reduced, and a method for using the same.

The annelid population and flat animal population control agent of the present invention are characterized by containing one or more compounds selected from the group consisting of 2-hydroxyethyl salicylate or a similar compound as an active ingredient. . Moreover, a higher effect can be obtained by including terpenes typified by L-menthol or vanilloids typified by vanillin. The annelids populations and flat animal populations composition for controlling an object to desired control (e.g., footwear, clothing, housing outer wall, etc.) sprayed, coated, directly to the distribution or annelids populations and flat animal populations, By bringing them into contact with each other, it is possible to achieve the above-mentioned purpose of controlling the annulus animal population and the flat animal population .

Providing at least one or more salicylic acid derivatives or annelids populations and flat animal populations control agent that the analogous compound as an active ingredient. Furthermore, terpenes or Baniro id such natural organic compound higher than by mixing annelid populations and flat animal populations control effect can be obtained consisting of. The control agent according to the present invention has a repellent effect as well as a repellent effect. In addition, since the control agent according to the present invention has a high drug holding power, it is effective in work in a forest with a lot of undergrowth and in the rain. In addition, it is intended to provide a simple usage method that can be easily used by children and persons with physical disabilities.

The annelid population and flat animal population control agent according to the present invention contain, as an active ingredient, one or more compounds selected from the group consisting of salicylic acid derivatives (2-hydroxyethyl salicylate, methyl salicylate, salicylic acid, etc.). and a liquid or solid substances consisting other terpenes or Baniro id compounds may include a mixture.

Salicylic acid derivatives that have been found to be effective in the present invention are salicylic acid, methyl salicylate, ethyl salicylate, and 2-hydroxyethyl salicylate. Of these, 2-hydroxyethyl salicylate was most effective. However, it is not limited to the above compounds.

Examples of the use of terpenes in the present invention include menthol and menthane, but are not limited to these compounds.

Examples of the use of vanilloids in the present invention include vanillin, but are not limited to these compounds.

Although mint oil was particularly effective as the origin of terpenes, it is not limited to this.

Although vanilla extract was effective as the origin of vanilloids, it is not limited to this.

The annulus animal population and the flat animal population control agent in the present invention exhibit a control effect without any particular processing, but higher convenience can be shown by making the solution.

As a method for forming a solution, dissolution in an organic solvent, emulsification with a surfactant, or dissolution in water by embedding in a microcapsule is effective. As the organic solvent, ethanol and the like which are not harmful to the body are preferable.

The solution-like annulus animal population and flat animal population control agent in the present invention can be easily sprayed by enclosing them in a spray container with a spray nozzle and a valve together with a compressed gas for spraying. This annelid and flat animal population control agent does not lose its control effect by spraying.

Annular animal populations and flat animal population control agents in the present invention are applied to absorptive objects such as paper, cloth, non-woven fabric, synthetic resin sheet, or gel-like substances such as gelatin and agar, sprayed, poured, immersed, kneaded, The control component can be released slowly by addition, mixing with a solid oil such as soap or wax, and kneading.
By this method, the control effect can be easily maintained for a long time.

The annulus animal population and the flat animal population control agent in the present invention are not harmful to animals and plants including humans, and are mainly environmentally-derived components and therefore have little environmental impact. From these, it can be applied to human or animal surfaces or footwear, clothes, machines, screen doors, glass, floors, walls, and any living area. In addition, since the ingredients are stable for a relatively long period of time and have high drug retention, they are also effective in working in forests with a lot of undergrowth and in the rain.

Annelida populations and flat animal populations control agent in the present invention also exhibits control effect is contacted directly annelids populations Oyo fine flat animal populations.
For example, a spray-type annelid population and a flat animal population control agent are directly sprayed to obtain a control effect.

In the experiment method, a circle of 8.6 cm in diameter is written with a pencil in the center of A6 size copy paper, and a reagent is applied outside the circle. I placed a Yamabiru in the circle, and examined the repellent rate to see if it could come out of the circle. The reagent is dissolved in 100% ethanol.

An experiment was conducted in which 2-hydroxyethyl salicylate was applied outside the circle at concentrations of 3, 5, 10, 15, 30, 40, 50, and 100 mg / 1 ml. As a result, the repelling rate was 0, 30, 80, 100, 100, 100, 100 and 100%.

Terpenes (L-menthol) were applied to the outside of the circle at concentrations of 3, 5, 10, 15, 30, 40, 50, and 100 mg / 1 ml, and experiments were conducted. As a result, the repelling rate was 0, 0, 0, 10, 20, 50, 100 and 100%.

Vanilloids (vanillin) were applied to the outside of the circle at concentrations of 3, 5, 7.5, 10, 15, 30, and 40 mg / 1 ml. As a result, the repellent rate of Yamavir was 0, 10, 50, 80, 80, 80 and 100%.

Table 1 is a table showing the relationship between the concentration of 2-hydroxyethyl salicylate, methyl salicylate, salicylic acid, acetylsalicylic acid, L-menthol, vanillin and capsaicin and the repellent rate.

Experiments were conducted by applying 2-hydroxyethyl salicylate outside the circle at a concentration of 5 mg / 1 ml and vanillin 7.5 mg / 1 ml. The repellent rate was 100%. Moreover, it was 100% when the amount of components was increased.

The experiment was carried out by applying 2-hydroxyethyl salicylate outside the circle at a concentration of 5 mg / 1 ml and L-menthol 40 mg / 1 ml. The repellent rate was 100%. Moreover, it was 100% when the amount of ingredients was increased.

Table 2 is a table showing the relationship between the concentration of 2-hydroxyethyl salicylate, L-menthol, vanillin and capsaicin and the repellent rate.

(Comparative Example 1)
An experiment was performed in which 100% ethanol was applied outside the circle. The repellent rate was 0%. Therefore, ethanol is used as the organic solvent in which the reagent is dissolved.
