Spontaneous colonizations of Panstrogylus magistus and Triatoma sordida in experimental fowl houses made possible the stage-frequency analysis so as to obtain some populational parameters. So adult mobility, average stage period, daily and stage survival rates were estimated. Annual period of adult dispersal was defined as Steptember-November for P. magistus and January-March for T. sórdita, at least in this region of Southeastern Brazil. It seems that T. sordida presents higher survival rates than P. megistus. Although the nymph stages periods were very variable, the total value was 298 days for P. megistus and 294 days for T. sordida. The authors presume that these data will be useful for control and surveillance of dweling infestations by these bugs.Downloads
