Abstract
Under
the laboratory conditions, toxicological evaluation of two compounds, Radiant
SC 12% and Hexaflumuron (IGR) EC 10% against eggs of Pectinophora
gossypiella (Saund.) and biological effect of these compounds on larvae,
pupae and adult emergence resulted from treated eggs was also studied. The
results revealed that LC50s were 3.15, 0.811and 0.522 ppm., when
one, two and prehatching days old eggs, respectively were treated with Radiant,
while LC50s were 3.754, 2.863 and 2.004 ppm, respectively for
Hexaflumuron. The obtained results show a prolongation in larval and pupal
developments resulted from treated eggs by Radiant, estimated by 20.8, 18.5 and
8.2 days, respectively for larvae and 8.9, 8.8 and 7.9 days for pupae. In case
of Hexaflumuron, duration were 22.3, 20.6 and 20.4 days, respectively for
larvae after egg treated and 10.8,10.0 and 11.3 days, respectively  for pupae. In contrast, in adult stage, the
results indicated high reduction in total eggs laid, percentage of hatchability
and longevity.
