いる。2. Description of the Related Art It has been known that human sweat attracts mosquitoes, but it is difficult to produce human sweat itself in large quantities and put it into practical use. Therefore, studies have been conducted on a component having a mosquito attracting activity in human sweat, and it has been revealed so far that (+)-lactic acid is one of the mosquito attracting active components.

Place in a 28 cm 3 cage and place a black glass tube (1.5 cm in diameter, 4 cm in length) on one end of which the test sample shown in Table 1 below is dissolved in an appropriate amount of acetone, uniformly coated, and air dried. A control black glass tube on which human sweat was sufficiently attached by gripping the edge for 30 minutes was placed, and the cumulative number of mosquitoes contacting the black glass tube was observed for 30 minutes. The evaluation was expressed by the "attraction ratio" obtained by the following formula.
【数１】 試験は、ガラス管の設置位置を交互に置き換えて４〜８
反復行い、その平均値を求めた。結果を表１に示す。[Equation 1] The test was carried out by replacing the installation positions of the glass tubes alternately with 4 to 8
Repeatedly, the average value was obtained. The results are shown in Table 1.
