Abstract
The present study included the effect of local rice varieties ( Anbar , Aqrawi , Baziani ) and imported varieties ( American , Vietnami and Thailandi ) and the effect of storage period ( 2, 4 ) months on the population density of saw toothed beetle and loss weight in seeds . The results showed that there was increase in the average of insect numbers with increasing storage period in which reaching the highest number ( 94.61 ) insect after 4 months of storage . The rice variety , Baziani was considered the more susceptible to insect infestation in which attained 134.33 insect after 4 months of storage . Viatnami variety was less susceptible to insect infestation in which attained 29.83 insect . The general average of loss weight of seeds were 0.51 and 0.75 g for tow storage period 2 and 4 months , respectively . Higher loss of weight seeds was between 0.08 for Thailand variety to 2.46 for Baziani variety which considered more sutible for insect growth .
