Efficacy of antimoultants against poplar defoliator Ichthyura anastomosis Steph and Shisham defoliator Plecoptera reflexa Guen.

ABSTRACT
Antimoultant insecticides, Alsystin and Dimilin 25% W.p.
which inhibit chitin sythesis in insects were tried
against 2nd and 3rd instar larvae of shisham defoliator,
Plecaptera refexa Guen. (Notodontidae). Both the
chemicals in laboratory as well as field trials, in
doses of o.02 and 0.04% concentrations gave cent percent
mortality of the larvae. The residual effect of the
insecticides continued up to about one month and
provided cover for two successive and overlapping
generations the non-target insects, which do not feed in
foliage were absolutely safe from the adverse effect of
the chemicals.
