Abstract
Laboratory studies were undertaken to assess the initial and persistence of lambada –Cyhalothrin insecticide on some porous and some non-porous surfaces. Formulation of insecticide was applied to polyethelyne and cement surfaces which are materials commonly used for grain storage facilities (packages) and in the construction of silos or storage. Lambada –Cyhalothrin insecticide was applied at concentrations 15.7, 7.8, 3.93, 1.9, 0.949 to 0.479g/m2 to test surfaces to determine Lc 95 to study their persistence against Rhyzopertha dominica and Callosobruchus maculates adults. Insects were exposed on treated surfaces Initial and residual efficacy was determined after 24 hrs. of insects contact with 7, 14, 30, 60, 90 , 120, 150, 180days of exposure deposits on each surface. Results indicated that; mortality rates were positively correlated with the concentration and negatively correlated with the time of application. Results indicated that:
-Polyethylene was the most persistent surface which gave 100% mortality up to 6 months in Callosobruchus maculates and up to 5 months in Rhyzopertha dominica at the highest concentration in both tested insects.
- In cement surface lambada cyhalothrin deteriorated very rapidly starting from the first month on both tested insects.
