Adults of the grain mite, Acarus siro L., were exposed 10 sub lethal doses of gamma irradiation (0-10 kR) then reared at temperatures of 5, ]5, or 25°C. The composition of the population at each temperature was counted every 8 days for 60 days, There was a negative correlation between the total mite population at 60 days and both rea1'ing temperature and irradiation. Interaction between temperature and irradiation was significant, with temperature being over 800 limes more effective than irradiation in reducing the mile population. An increase in population occurred at dose levels of 1-5 kR in the F1 or F2 generation. However, a significant detrimental long-range (F4 or more) effect resulted from the sub lethal irradiation dose of the Fp generation.
