Biochemical and electrophoretical studies of the effect of some chemosterilants on theenzymes of aedes aegypti (L.) larvae.

In vivo effect of standard and prospective chemosterilants on some enzymes is reported. Colorimetric and histochemical findings indicate that alkaline phosphatase is inhibited by shikonin, hempa, tepa and shikonin angelate. Cholinesterase is inhibited by all the compounds while diphenol oxidase is not inhibited. These findings have been discussed in the light of the earlier observations.
