Although fenpropathrin possessed leaving activities to the carmine spider mite, the mites did not avoid leaf discs treated with 1 ppm of this compound when both treated and untreated leaf discs were placed alternaterly. The mites whcih arrived at the untreated leaf discs stayed there for an average of 83 seconds, while those arriving at the treated discs moved away without feeding. When the mites were dipped into 0.1 or 1.0 ppm solution of fenpropathrin and then were released at the center of a filter paper (11 cm in diameter), they moved straighter and left the filter paper more promptly than untreated mites did. From these results, this type of action of fenpropathrin can be called a locomoter stimulant. The sensitive sites of the carmine spider mite to fenpropathrin seemed to be on their legs or gnathosoma.
