Wood pellets are used by Biomass-solid refuse fuel (Bio-SRF) has been imported from many East-Asia countries especially,Vietnam in Korea. Wood pellets are made through grind and high-pressure process shows different physical characterizationlike high methyl bromide (MB) absorption unlike other wood materials. Furthermore, detected pests in wood pellets havesimilarity with detected pests in stored grain. In this study, we analyzed susceptibility on pupa and adult stages of redflour beetle, Tribolium castaneum in wood pellets against mixture of MB and phosphine (PH3). Mixture treatment ofMB and PH3 was more effective than single MB treatment compare with control. Pupal stage showed more tolerant thanadult stage on each fumigant and 100% mortality was determined at 27 mg/L of MB only at 20°C. However, PH3 increasedMB toxicity on pupae that 100% mortality was observed at 100:1 ratio of MB (5 mg/L) and PH3 (0.05 mg/L) at 20°C.Based on this study, mixture treatment of different type of fumigant will be applied to control of quarantine pests.
