Abstract
Whole body irradiation is known to shorten the life-span of insects. This is further investigated in aquatic insect larvae, as part of a programme concerned with stress responses on these larvae. The effect of gamma rays on the longevity of different larval instars of midge Chironomus Riparius was investigated by using five doses of 1, 9, 30, 200 and 1000 Gy of gamma rays. Lt{sub 50} (the time in days required for killing 50% of the population) was estimated using spss{sup x} programme. Data showed that irradiation decreased Lt{sub 50} in the second, third and fourth instars in comparison to their control, while in the first instar, irradiation increased Lt{sub 50} for all doses used. Shortening or increasing life was independent of the dose. Results were explained in terms of possibility of inhibition of enzymes. 1 fig., 1 tab.
