ResumenMethyl bromide (MB) damages the ozone layer; therefore, the use of phosphine from cylinders applied directly in gaseous form was studied as an alternative for the control of Sitophilus zeamais Motschulsky in stored maize. Three factors were considered: 1) phosphine concentration, testing 100, 200 and 300 ppm and a control with 0 ppm; 2) exposure time, with a first set of 6, 10, 18, 24 and 48 hr, and another of 2, 3, 4, 6 and 8 hr; and finally 3) temperature, with 5°C for the first set of exposure times, and 21 and 30°C for the second set. The TL<sub>50</sub> and TL<sub>90</sub> were estimated by probit analysis; mortality data were examined statistically by analysis of variance and regression. Comparisons of TLs among temperatures show a significant difference in all cases; lethal times were significantly shorter as temperature increased. Comparisons of TLs among concentrations revealed that, statistically, the TLs corresponding to 100 ppm, were different from those of 200 and 300 ppm, and that high concentrations were statistically indistinguishable. An effective control of S. zeamais was obtained at all temperatures tested: at 5°C, the concentration of 200 ppm during 24 h produced 100% of mortality; at 21°C, the concentration of 300 ppm during 8 h generated a mortality near to 100%; and at 30°C, a mortality of 100% was obtained using a concentration of 200 ppm for 6 h.es_ES
