1. Pesticide test

The particle board sheet piece on which the pine needle cyst eggs were placed was inoculated on a silk mate cut round to a thickness of 1 cm, and the silk mate was inoculated by placing the pine needle larvae eggs in a direction not in contact with the silk mate. The egg-inoculated silk mate was treated with the first pesticide, the second pesticide, and the fumigant prepared according to Examples to seal the envelope, and the envelope was placed in a petri dish. At this time, only the bag was sealed without treatment with the first control agent, the second control agent, and the fumigation agent in the control group.

And the charlet was placed in a constant temperature room at 25° C. set to turn on the light for 12 hours per day. After 12 days from egg inoculation, the chalet was taken out and the number of viable larvae was counted.

The control rate was calculated by the following formula, and the results are shown in [Table 1] below.

Control rate (%) = 100 × (1 - treatment group survival rate / no treatment group survival rate)
