Movement behaviors of specimens of mite (Tetranychus urticae) were computationally analyzed after the treatments of pesticide, abamectin, at a low concentration of 0.78ppb. During the observation period, test specimens were placed individually on the bean leaves (diameter=7mm), and their position was recorded in 2-dimension at 0.25 second intervals (8 hours before treatment and 8 hours after treatment). The selected parameters such as speed, angular change, meander, etc, were checked for characterizing response behaviors after the treatments. The difference of mite behavior was accordingly observed after the treatments, and the time spent in the center area appeared to be longer after the treatments. Additional characterization of movement behaviors was computationally checked, and utilization of behavioral monitoring in pest management was further discussed regarding early detection of susceptible or resistant strains.
