Life-history parameters of two different forms of Panomychus akitanus EHARA were compared under 25℃ and 15L-9D. One (stiped-egg form) was collected from Sasa senanensis in Sappro, and the other (stipless-egg form) from Sasa apoiensis in Tomakomai. The total developmental time was shorter in the Sapporo population than in the Tomakomai one.The intrinsic rate of natural increase (r_m), net reproductive rate (r_0) and mean generation time (T) were determined as follows : the Sapporo population : r_m, 0.200,R_0,59.56 and T, 23.56; the Tomakomai population : r_m, 0.184,R_0,44.65 and T, 22.32. The difference of r_m-values found in the two populations was considered to be due to the differences in the microhabitat ocupied and its distribution pattern.
