Changes in the total count. . protein content, pH and
hemocyte picture of the haemolymph from the fourth instar
larvae irradiated as full grown male pupae of Spodoptera
littoralis with loo and 200 gray were determined. The total
hemocyte count decreased by 22.% with the dose 100 Gray and
by 57.4% with the dose 200 gray as compared with the con
trol. The amount of haemolymph protein decreased to half at
the dose 200 Gray and by 28.6% at the dose 100 Gray less
than control. Gamma radiation did not affect pH. Hemocyte
picture had some changes in morphological form by gamma
irradiation.
