Abstract
ABSTRACT
Dates are exposed to many insects pest in all its stages of maturity. Ephestia cautella
is the major insect pest attacking dates at harvest time and storage particularly Siwy
and Frihy cultivars. Five insecticides (Tracer, Radiant, Coragen, Pleo and Achook)
from new groups were selected as safe alternatives to human and environment
against E. cautella in storehouse of Siwy and Frihy dates. Three concentrations of
each insecticide (single, half and double concentrations) were sprayed on clean and
untreated fruits of each cultivar for storing. The single concentration was a
prescribed concentration, based on the recommended concentration to be used on
different crops. Half concentration did not appear to be effective in all insecticides
used on both cultivars, the double concentration was achieved 100% mortality during
larvae stage period and single concentration was effective particularly in Radiant
while Tracer was the lowest influence on insects. Data exhibited no significant
changes in the main chemical composition of these treated dates. The residual levels
of tested insecticides in the fruit were studied after 28 days from application.
