Most of
the surviving larvae that were exposed to
neem seed kernel + Aloe vera + Calotropis
+ Clerodendron leaf extract at 1.0 to 2.5
per cent died at the pupal stage (7.46 to
21.16 % mortality). The next best product
in causing larval and pupal mortality
(36.03 to 87.46 %) was neem fruit + red
chilli + custard apple leaf extract (0.5 to 10
% concentration).
