AbstractAbstract
[en] The dispersion behaviour and distribution pattern of Sitophilus zeamais Motschulsky, 1855 through a bulk of corn, rice and wheat,leaving from a infestation focus, was investigated by means of tracer methodology. Adults insects were labeled with the gamma emitter 131 I, through bath in Na 131 I solution and released onto the top of grain mass deposited in cylinders each 430 mm height and 195 mm in diameter, filled to 20 mm of the top with grains. The cylinders were enclosed with lids. The insects were detected through the bulk of the grain by means of a crystal scintillator, in fourteen sites, zero 3, 6, 12, 24, 48, 72, 96 and 120 hours after releasing. (author)
