JP4473619B2 - Mite attractant, tick attracting material, and mite attracting method - Google Patents

Description

  The present invention relates to a tick attracting agent, a tick attracting capturing material and a tick attracting method using the tick attracting agent.

  In recent years, due to the high airtightness of houses due to the advancement of building technology, the spread of air conditioners and the laying of carpets, etc., the condition of favorable conditions for mite habitat has been prepared and the propagation of mites has been promoted. . Mites are especially inhabited by bedding such as futons, carpets, and sofas, and they cause allergic diseases such as bronchial asthma and allergic rhinitis, and dermatitis, so effective extermination is required.

  As a method for combating ticks, there are methods of spraying acaricide and physically eradicating with sun-dried or vacuum cleaners. When an acaricide is used, there is a problem in that it is not preferable for bedding and the like, and a dead body of a tick is still left as an allergen in a place where a tick is still inhabited, for example, bedding or a carpet. In addition, a simple physical removal method requires a great deal of labor.

Therefore, mite attractants and mite capturing materials that solve this problem have been studied (Patent Document 1, Patent Document 2, Patent Document 3). Patent Document 1 discloses a tick attracting composition containing as an active ingredient one or more compounds selected from linear fatty acids having 4 to 18 carbon atoms. Patent Document 2 discloses a tick attractant containing food flavors such as chocolate flavor, almond flavor, cheese flavor, strawberry flavor, butter flavor and sesame flavor as active ingredients. And patent document 3 is disclosing the tick attractant which uses the said food flavor and triglyceride as an active ingredient.
However, it is not yet known that lactones having 4 to 14 carbon atoms according to the present invention have an excellent tick-inducing effect.
