The development of Sitophilus oryzae (L.) in relation to temperature was studied on rice. The total developmental periods on rice were similar to those reported on wheat. A model constructed by combinging those of Logan et al. (1976) and Wollkind et al. (1978) provided a good description of this weevil's development throughout the range of lower and upper threshold temperatures. The lower and upper threshold temperatures for overall development of the weevil were estimated to be 15.0° and 34.1°C.
