Temperatures in excess of 50° produced by focused solar dryers can be used for disinfestation of dried foods. All life stages of the hide beetle, Dermestes maculatus, were eliminated from dried mullet in a single exposure of 30–60 min. The same results were obtained with the Indian meal moth, Plodia interpunctella with dried peaches and with the merchant grain beetle, Oryzaephilus mercates on oatmeal. Among packaging materials, black plastic was shown to be most effective followed by clear plastic. Aluminum foil was found to be reflective and resulted in lower temperatures within the container. The lethality of oven, microwave, and infrared heating units were also tested on the life stages of the hide beetles.
