Abstract
The lower concentrations of the chemical, kinoprene i.e. 0.01 ml and 0.02 ml per litre of water were ineffective to produce the mortality of the larvae when 3rd instars were exposed for 24 hours, although a considerable pupal mortality was observed at these concentrations. These concentrations, however, affect the emergence of adults from the pupae so formed. The mortality rate of larvae and pupae was found to be much higher when 3rd instars were treated with high concentrations of 0.4 and 0.1 ml/litre. The chemical lso adversely affect the emergence of adults from such pupae.
