Fumigation Activity against Phosphine-Resistant Tribolium castaneum (Coleoptera: Tenebrionidae) Using Carbonyl Sulfide
Phosphine resistance is occurring among stored-grain pests worldwide.This study investigated the fumigation activity of phosphine (PH3) and carbonyl sulfide (COS) against domestic strain (d-strain) Tribolium castaneum, resistance strain (r-strain) T.castaneum and Oryzaephilus 1 Ball Totes surinamensis.All developmental stages of the pests were expo
