Susceptibility of the developmental stages of Callosbruchus maculatus (F.) to gamma radiation was studied by irradiating infested cowpea grains. Irradiation of one-day-old eggs at doses ranging from 16 Gy to 24 Gy resulted in 100% mortality; and mortality was 65.0 and 85.0% in three-day-old eggs and seven-dayold grubs, respectively, at the dose of 24 Gy. A dose of 150 Gy was required to cause 70.0% mortality in ten-day-old grubs. Exposure of four-day-old pupae to gamma radiation (100 Gy and above) completely inhibited adult emergence. 100% mortality of both sexes occurred by the thirdday at 1500 Gy. However, irradiation at a dose of 24 Gy induced complete sterility in adults of C. maculatus. Adult emergence from infested grain was significantly reduced due to gamma irradiation. Gamma radiation did not alter the protein and carbohydrate contents of irradiated cowpea grains. [ABSTRACT FROM AUTHOR] |
