Techno oil and Berna star are two plant extracted products which are used as safe pesticides. Tribolium castaneum (Herbst) and Rhyzopertha dominica (F.) are two major stored product insects. The two tested products were evaluated against R. dominica and T. castaneum adults using two bioassays evaluating their repellency and contact effects. Berna star had stronger repellent activity against T. castaneum. In contrast, Techno oil had the greatest repellency against R. dominica. Furthermore in thin film method Berna star had stronger effect against the two tested insects compared to Techno oil at all exposure periods. After 24 h of exposure the two components had no effect on T. castaneum while after 72 h of exposure the mortality was 100% with all concentrations for R. dominica for two tested components. Using mixing with medium method there was no effect on T. castaneum before 7 days for both tested components, while for R. dominica both tested components had toxicity effect for all used concentrations. For R. dominica after one, three and four days of exposure Techno oil had the stronger effect while for T. castaneum Berna star had stronger effect at all exposure periods. Based on LT50 with the highest concentration (40000 mg/kg) Berna star had stronger effect on both tested insects with LT50 of 6.06 and 1.41 h for T. castaneum and R. dominica respectively. Both tested products achieved 100% reduction against the two tested insects.
