Abstract

The current study was conducted to investigate the effect of microwave extract of Turkish oleander A. curassavica by direct and indirect spraying methods on the mortality rates of T. castaneum instars with concentrations of 0.100, 0.200, and 0.300 mg/ml for the microwave extract. The results showed the superiority of the direct method of spraying over the indirect method of the two extracts and for all stages of the insect, as the killing rate of the direct method of the microwave extract was 57%, and the concentration of 0.300mg/ml gave the highest killing rate of 66.1%.
