BIO-CONTROL OF RAW DIATOMACEOUS EARTH ALONE OR IN COMBINATION WITH PERMETHRIN DUST AGAINST RHYZOPERTHA DOMINICA (COLEOPTERA: BOSTRYCHIDAE) ON STORED WHEAT (TRITICUMSPP)

Laboratory experiments was carried out to evaluate the efficacy of raw DE alone or/in combination with permethrin dust against R. dominica on wheat, to assess insect mortality caused by exposure to raw DE and/ or permethrin, effects on progeny production of exposed beetles and prevention of grain damage by the test insect. R. dominica was obtained from laboratory cultures which has been maintained in the laboratory for over year, where F1 progeny was used for the experiment.
