Abstract: Dates are subject to infestation by nitidulid beetles during and after harvest. Fumigation of dried fruits with methyl bromide (MB) upon arrival at the packing plant effectively controls infestation and also causes a high proportion of larvae and adults to emigrate from the fruit before they succumb. This work was undertaken to investigate the effectiveness of heat treatment as an alternative to MB, which would remove insects from the dates and prevent insect development and preserve fruit quality. Dates grown in Israel served as a model for development of this technology to be integrated as part of the existing dates drying system.
