Result of phosphine fumigation by mactoxin application at 27.9 deg. celsius, 81.5 % indicated that the pupal stage of cigarette beetle, Lasioderma serricorne F. was more tolerant to phosphine than the 4th larval and adult stages. The concentration of phosphine at 55-125 ppm, 48-hour fumigation or 65-115 ppm, 72-hour fumigation could kill 100 % of the population. Short exposure period such as 24-hour fumigation did not give good result for complete control of the pupae though the concentration was as high as 120 ppm.
