Methoxychlor, lindane, malathion and pyrenone dusts were tested against Pagiocerus fiorii (Egger) in stored soft corn. In corn that was less than 1% attacked, methoxychlor at 50 p.p.m. gave protection for over 9 months and in field trials prevented population buildup for 8 months in corn that was less than 10% attacked at the time of treatment. Lindane at 10 p.p.m. and pyrenone at 1 pound per 10 bushels gave protection for 6 to 7 months when the corn was less than 1% infested.
