Abstract
Comparisons of esterase activity between the 4th instar larva and pupal stage of Chironomid species were made at the Molecular Biology Laboratory, University of Dhaka during 2008 using 7.5% Polyacrylamide gel electrophoresis (PAGE). The staining substrates were α and βnaphthyl acetates. The study on Chironomid species was conducted during January to December, 2008 in the Genetics & Molecular Biology, Department of Zoology, University of Dhaka, Bangladesh. Esterase Zymograms were prepared from 4th instar larva and pupa. Chironomid larvae showed a stage-specific variability in esterase expression. The maximum four esterases were assigned in this experiment Est-1, Est-2, Est-3 and Est-4 with different relative mobilities. But these four esterases were detected in 4th instar larva. Pupa possessed only one esterase (Est-1).
