In India coffee seeds packed in jute bags and stored in warehouses are infested with coffee bean weevil (Araecerus fasciculatiis). To control this insect, fumigation with methyl bromide (MB) is in practice. Although methyl bromide for phytosanitary use is protected under Montreal Protocol, MB fumigation of green coffee may become severely restricted and prohibitively expensive in the future. Further, use of MB may also contribute to the global warming. Therefore, alternatives to MB fumigation are needed. This study involved the usage of aluminium phosphide as an alternative fumigant for methyl bromide to control the storage pest and coffee bean weevil. A laboratory study was carried out with different levels of aluminium phosphide concentration forfumigating monsooned coffee infested with Araecerus fasciculatus and fumigated at different exposure period.
