This preparation was diluted with water so that the concentration of the present compound or the comparative compound (A) became 500 ppm.

Meanwhile, about 60 Tetranychus urticae female imagoes were released on a vineless common bean plantlet (7 days after seeding, first leaf development phase) planted in a plastic cup, which was allowed to stand for 1 day. To this plantlet was sprayed 20 ml of each of the above diluted solutions.

Eight days after spraying, the number of surviving mites on a leaf of the vineless common bean was investigated, and a controlling rate was calculated according to the following equation.

Controlling rate (%)=100×{1−(number of surviving mites of treated group)/(number of surviving mites of non-treated group)}

As a result, in all groups treated with each of present compounds (1) to (3), (5), (17), (39), (55) to (57), (120) to (124), (129), (130), (135), (136), (139) to (141), (232), (236), (243), (255), and (262), a controlling rate was not lower than 90%, but a controlling rate was 0% in the group treated with the comparative compound (A).
