It was investigated whether or not the local of cultivation of rice affects the posterior susceptibility to Sitotroga cerealella of the grain in storage. Samples of rough rice from the same bulk of seeds, of the variety Dourado Agulha, were planted in four regions of the State of São Paulo, Pindamonhangaba paddy, Pindorama upland, Mococa paddy. Campinas paddy and Campinas upland. The rice, after having been harvested, was taken to Campinas where - after one year and half of storage under uniform conditions for all samples - it was tested for its susceptibility to the insect, by using samples of each local replicated 10 times randomly distributed inside of an insect cage. The progeny of insects of each sample was recorded daily. The trial was repeated twice. The results showed that the local of cultivation has influence upon the posterior susceptibility of the grain in storage. The rice grown in Pindorama was more damaged by the pest than the rice grown in other regions. There was no significant difference in susceptibility between the paddy and upland rice grown in Campinas. Scheffe's test indicated that there was a strong contrast between the paddy rice grown in Pinda-monhangaba, Mococa and Campinas and the upland rice grown in Pindorama and Campinas, the latter being more infested. Although the locality may account for this difference, there was a tendency for the upland rice to be much more infested in storage by S. cerealella. The period between infestation and the beginning of emergence of the first adults was of 23 days, showing that under favorable conditions this pest may give one generation each 25 days, in rough rice.
