Abstract

Action thresholds were calculated to be 1.7 H. similis and 1.9 D. soluta per rice plant. These densities are equivalent to 7,140 H. similis and 7,980 D. soluta per 10 sweeps. Densities equal to the action thresholds of these two species have not been observed in rice fields of Valle del Cauca, Colombia.
