A diluted aqueous solution of the suspension of Compound 1 was applied to a tile (15 cm x 15 cm) at a treatment rate of 40 mg / m² of Compound 1. 2The tile was sprayed in the following manner. As a negative control, water was sprayed on another tile. The sprayed tile was left undisturbed indoors for one day. Ten Argentine ant workers were released into a plastic cup (diameter: 10 cm) coated with Fluon® PTFE AD911E on the wall surface. The treated tile was placed over the cup so that the treated surface was on the inside, and the cup was fixed in place. The cup was then inverted to allow the ants to come into contact with the tile for one hour. After one hour, the cup was inverted and the tile was removed. The ants were given food and water, and the number of individuals suffering from distress and those who died 7 days after the contact was investigated. The distress death rate (%) was calculated using formula 1 below. The distress death rate in the treated group was corrected using Abbott's method shown in formula 2 below, using the distress death rate of the negative control. Note that a dead individual refers to an individual that has completely ceased activity, and a distressed individual refers to an individual that cannot get up when placed on its back. [Equation 1] Bitterness death rate (%) = {(Number of dead individuals + Number of individuals suffering) / Number of individuals tested} × 100 [Equation 2] Corrected bitterness death rate = (Bitterness death rate in the treated group - Bitterness death rate in the negative control) / (100 - Bitterness death rate in the negative control) × 100 The same tests were conducted for compounds 4, 6, 19, 22, and 24.

[0137] <2. Direct Oil Spray Test> Test Example 2-1 Ten Argentine ant workers were released into a plastic cup (diameter: 10 cm, height: 4.5 cm) lined with filter paper, which had been coated with Fluon® PTFE AD911E to prevent escape on the wall surface. The cup was placed in the center of the bottom of a box-shaped chamber (46 cm x 46 cm x height 70 cm). 0.5 mL of a 0.004 wt% formulation of compound 22 (a formulation obtained by dissolving compound 22 in a mixture of dimethyl sulfoxide, isopropyl alcohol, and Isopar M (an isoparaffinic solvent manufactured by ExxonMobil) in a weight ratio of 15:35:50, and adjusting the concentration of compound 22 to 0.004 wt%) was sprayed into the cup from a height of 60 cm from the bottom of the cup using a spray gun (RG-3L ANEST IWATA AIR) at a spray pressure of 0.041 MPa. After spraying, the test insects were transferred to a new cup, given food and water, and the number of dead and suffering individuals was investigated 7 days after the spraying. The percentage of insects that died from suffering was calculated using the following formula 1. A dead individual is defined as an individual that has completely ceased activity, and a suffering individual is defined as an individual that cannot get up when placed on its back. [Formula 1] Percentage of insects that died from suffering (%) = {(Number of dead individuals + Number of suffering individuals) / Number of test individuals} × 100 The same test was conducted for compounds 1, 4, 16, 19, and 24. The test results showed that compounds 1, 4, 16, 19, 22, and 24 all exhibited a percentage of insects that died from suffering of 60% or more.

[0138] Test Example 2-2: The insect mortality rate was determined according to the method described in Test Example 2-1, except that a 0.02% by weight formulation of Compound 22 was used instead of a 0.004% by weight formulation of Compound 22 (a formulation obtained by dissolving Compound 22 in a mixture of dimethyl sulfoxide, isopropyl alcohol, and isopar M in a weight ratio of 15:35:50, and adjusting the concentration of Compound 22 to 0.02% by weight). The same tests were conducted for Compounds 1, 4, 16, 19, and 24. The test results showed that Compounds 1, 4, 16, 19, 22, and 24 all exhibited an insect mortality rate of 60% or more.

A predetermined amount of this solution was added dropwise to 1 g of feed, which was a mixture of granulated sugar and skim milk in a weight ratio of 1:2, and the resulting feed composition was air-dried. After air-drying, 0.5 mL of water was added to the feed composition and kneaded to obtain a test feed. The concentration of Compound 19 in the test feed was 5 ppm. The test feed was placed in a plastic cup (diameter: 10 cm, height: 4.5 cm) together with 10 Argentine ant workers and cotton wool soaked in water. Seven days after placing the test feed, ants, and cotton wool in the cup, the number of dead and suffering individuals was investigated, and the rate of death due to suffering (%) was calculated using the following formula 1. A dead individual refers to an individual that has completely stopped moving, and a suffering individual refers to an individual that cannot get up when placed on its back.

The same procedure was followed for compounds 1, 16, 19, 22, and 24. As a result of the tests, compounds 1, 4, 16, 19, 22, and 24 all showed a rate of insect death due to bitterness of 60% or more.

[0142] In Test Example 3-3, the rate of insect death due to bitterness was determined according to the method described in Test Example 3-1, except that compound 4 was used instead of compound 19, and the concentration of compound 4 in the test feed was set to 500 ppm. The same procedure was followed for compounds 1, 16, 19, 22, and 24. As a result of the tests, compounds 1, 4, 16, 19, 22, and 24 all showed a rate of insect death due to bitterness of 60% or more.

[0143] The present invention provides an ant control method that exhibits excellent efficacy.
