Potential of bifenthrin and chlorfenapyr for the management of Rhyzopertha Dominica (Fab.) and Tribolium Castaneum (Herbst)

The Tribolium castaneum (Herbst) and Rhyzopertha Dominica (Fab.) are potential pests of stored wheat products that causes destruction to grains all over the world. current investigation was planned examine bifenthrin chlorfenapyr for T. (red flour beetle) R, (Lesser grain borer). A total 50g sample taken in jars. Both were applied at concentrations 0.25, 0.5, 1, 2, 4ppm, separately. Factorial design under CRD used each treatment replicated thrice. rate mortality recorded timely intervals 12, 24, 48, 72 96 hours accordingly. All treatments showed statistically significant results with doubling dose insecticide but some non-significant as well. However, highest caused by noted98.746% case while 89.643% R. after hours. Results proves more lethal against castaneum.
