Velvet bean, however, proved lethal in the laboratory as well as it was found free from damage by the Bihar hairy caterpillars. Regults of the chemical control suggest that the labomtory findings are not always successful to the same extent. Hence, field studies should be the basis of recommendationsof a pesticides against a particular insects. There is plenty of scope for conducting trials on the breeding and utilisation of Ganthecona bug in controlling the insects. Nuclear polyhedrosis has a potential value for the control of the insects. This may be taken up for a detailed study.EnglishThesis
