This experiment was carried out to study the effect of increasing gamma
radiation doses (up to 24 GY) on the eggs of Callosobruchus maculatus, at
different ages, to determine their effect on egg hatching rate, and other
biological traits of the em
erging adults from eggs treated with sub – lethal
doses.
It has been noticed that the low gamma radiation doses killed most of the
one –day old eggs before hatching, and no adult insect could emerge from
hatching those eggs, and the dose of 12GY caused the same effect, but on two
day-old eggs. when eggs were at the age of 3, 4, and 5 days, gamma radiation
didn’t have influenced on the embryo development, but demise percentage,
increased after hatching.
The percentage of emerged adults was only 1.8% for the eggs treated with
16 GY gamma radiation.
