The acute lethality and reproductive potential of one-week- old adult Rhyzoper/ha dominica (F-) were determined at various exposures ranging between 5 and 320 kR of gamma rays. Observations revealed that exposure of 320 kR killed all the beetles during irradiation. Treatments of 20 kR or greater produced 100% mortality within 4-25 days, depending on the exposure. Beetles surviving the 5 kR exposure for the 1st 30-day-post treatment period lived as long as the controls. The exposure of 5 kR or greater resulted in the permanent sterility of both sexes of the beetles. Practical and radiobiological implications of the findings are discussed.
