Abstract

   The ability of the fungus Beauveria bassiana was tested when exposed to ultraviolet light at   a wavelength of 312nm for 4 and 8min. A significant decrease was observed in the percentage of emergence with increased fungal concentrations, and the percentage of albumin in the blood decreased by 14.30 and 16.10µg.ml-1 for adults of the fig moth, Ephestia cautella that spawned from pupates at the age of (1-2) and (6-8)days, respectively, when sprayed to fungus solution irradiated for 4min. at a concentration of 1.5×107spore.ml-1 compared with adult insects that resulted from pupates, when sprayed to a fungus solution that is not exposed to radiation, they reached 28.12 and 28.15µg.ml-1, respectively, and the amount of glucose in the blood also decreased, reaching 24.00 and 34.00µg.ml-1 for adult insects that resulted from pupates at the age of (1-2) and (6-8)days, respectively. The number of the hemocytes decreased 119 and 155cells, respectively, for adult insects that resulted from pupates sprayed to the irradiated fungus, while 185 and 220cells to insects that resulted from pupates sprayed with the same concentration of non-irradiated fungal solution.
