The objective of this work was to verify the damage provoked by artificial infestation of Rhizopertha dominica and Sitophilus sp., isolated and in association, on physical and physiological quality of irrigated rice seeds stored for 180 days in the laboratory. Basic seeds of cultivar BR-IRGA 410 with 12% moisture content were stored from September 1992 to March 1993 in plastic pots kept in a BOD. type oven stove. Physical quality evaluation was made by quantifying infested seeds, moisture content, 100 seeds weight, and loss of weight during storage, whereas the evaluation of seed physiological quality was made through germination percentage, grenhouse emergency, speed emergency index, and electrical conductivity. The evaluations were carried out every 30 days over a 180 day storage period. The results showed that the populations of Rhizopertha dominica were more active in reducing the vigor of irrigated rice seeds under storage, as compared to the ones of Sitophilus sp.The irrigated rice seeds artificially infested by populations of Rhizopertha dominica and Sitophilus sp. during stored, shouwed reducing in the weight, germination percentage, and greenhouse emergency while leakage of increased soluts when infested by twenty insects/ 100g seeds.
