ABSTRACT

Stress response to sodium azide, 2-4 dinitrophenol and benzamide was analyzed in polytene chromosomes of pupal foot pad cell of Parasarcophaga ruficornis. Stress was given for different time intervals. In each case, only a single large puff was induced in chromosome arm II L at the region 12A. The same puff was induced in other Sarcophagid species by heat and chemical stress. It appears that a single conserved prominent puff is a hall mark of the stress response in Sarcophagids.

Key words : Banda, Chemical stress, P. ruficorni.
