Insecticidal Effect Of Some Botanical Formulations On Mortality Of Red Flour Beetle Tribolium Castaneum Herbst (Coleoptera: Tenebrionidae).

Abstract

Laboratory experiments were conducted at the College of Agricultural Studies,

Sudan University of Science and Technology, to evaluate the insecticidal effect

of korobi Nerium oleander L, Damas Conocarpus lancifolius Engl and

Mahogany Khaya senegalensis (Desr. A.Juss). against red flour beetle Tribolium

castaneum Herbst.

Three formulations (powder, aqueous and ethanolic extract of each plant were

used under three concentrations . Three concentrations from each plant (5%,

10% and 15%) were used in this study. The results showed that all

concentrations of all tested plants in various formulations gave significantly

higher mortality percentage than the control after 24hrs of exposure.

The highest concentration (15%) of Nerium leaves powder revealed only 38.4%

mortality after 72 hrs of exposure, whereas, the same concentration of Nerium

leaves aqueous and ethanolic extracts gave higher mortality percentage (48.4%).

Meanwhile, the highest concentration of Damas leaves aqueous extract generated

only 38.4% mortality after 72 hrs of exposure, whereas, the same concentration

of Damas leaves ethanolic extract caused 41.7% mortality.

The obtained results also revealed that the highest concentration of Mahogany

leaves powder, aqueous extract and ethanolic extract induced 25%, 31.7% and 55% mortality respectively after 72 hrs of application.
