Abstract
Pupae of the mosquito, Culex Pipiens L. Were gamma-irradiated with 3 doses (40, 60 and 80 Gy) and compared with nonirradiated group for nucleic acids in the newly emerged adults; 24, 48 and 72 hours post-emergence. Nucleic acids were estimated in starved adults or blood-fed females. The results showed that RNA content in the normal or irradiated unfed males or females decreased with time after emergence. Irradiation at different doses decreased RNA content in males after 48 and 72 hours. However, in females, irradiation at low doses had no effect after 24 hours but the effect was clear after 48 and hours. Gamma irradiation led to decreased RNA content in females after 72 hours post feeding on blood. This decrease was insignificant at 40 Gy but highly significant at 60 and 80 Gy. Normal males had a constant DNA content at all periods. However, irradiation reduced this content at 40 and 60 Gy, especially after 72 hours. At 80 Gy, DNA showed an increase at first then was reduced reaching the control value after 72 hours. Irradiation and time slightly reduced the DNA content, especially at 72 hours. Irradiation with 60 and 80 Gy showed a pronounced increase in DNA

The RNA/DNA ratio decreased by irradiation of non-fed males and females, while in the control blood-fed females, this ratio was higher after 72 hours post feeding than that unfed ones. The ratio decreased in irradiated females with increasing gamma dose after 72 hours post feeding. 8 figs.}
