- ... Action thresholds for Tibraca limbativentris Stall (TL) on rice were calculated to be 8.8 and 25.8 TL per 10 sweep nets for 30- and 40-day old plants, respectively. Population dynamics of TL at two localities in Valle del Cauca, Colombia, indicated a density of 1.2 TL per sweep (12 TL per 10 sweeps). Densities equal to the calculated action thresholds were not observed in rice fields in Valle del ...
