Compound numbers: 1, 3, 4, 6, 7, 9, 10, 11, 13, 29, 30, 35, 36, 39, 40, 42, 43, 52, 53, 54, 56, 57, 59, 64 , 65, 238, 239, 240, 247, 248, 249, 250, 257, 258, 263
The miticide rate of chlordiform used as a control was 40%.

(Test Example 2) Efficacy against Haemaphysalis longicornis A 20 mL glass vial was thoroughly washed with acetone by the day before the test and used for the test.
The test compound was dissolved in acetone at 4000 ppm, and a diluted solution having a common ratio of 10 was further prepared with acetone.
0.118 mL of an acetone solution was added to the vial, and the vial was rotated while blowing with a dryer to volatilize acetone to form a thin film of the compound (when using a 400 ppm solution, the concentration was 1 μg / cm 2 ).

In this, young ticks (15-40 heads / vial) were inoculated, the lid was quickly closed, and the number of test individuals was counted after the movement of ticks settled down. At this time, unhealthy individuals were excluded.
Thereafter, the sample was left in an observation room (25 ° C., in the dark) for 5 days, and a life-and-death determination was performed over time, and an insecticidal rate was calculated. As a result, the following compounds showed an insecticidal rate of 90% or more.
Compound numbers: 3, 4, 6, 10
