These densities are equivalent to 7,140 <em>H. similis</em> and 7,980 <em>D. soluta</em> 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.}, number={1-2}, journal={The Journal of Agriculture of the University of Puerto Rico}, author={Arciniegas, Isabel C. and Pantoja, Alberto and García, César and Duque, Miriam C.}, year={1999}, month={Apr.}, pages={65–74} }
