Susceptibility of Sitophilus granarius (L.) to three herbal insecticides under laboratory conditions

Sanaz Emami, Seyed Ali Safavi and Azadeh Jarrahi

The granary weevil, Sitophilus granarius is one of the most important pests of stored products. This pest is internal feeder and causes considerable damage to cereals. In this research, three herbal insecticides including Sirinol, Palizin and Tondexir were evaluated for their efficacy in the control of S. granarius under laboratory conditions. The LC16.6, LC25 and LC50 values of Sirinol, Palizin and Tondexir were estimated on adult insects. Results showed that LC50 values for Sirinol, Palizin and Tondexir treatments were 3019.7, 1793.6, 1947.8 ppm after 24 hours, respectively. Our results demonstrated that Palizin was the most effective insecticide. There were significant differences (P<0.001) in the mortality of adult beetles when treated with combination of three herbal agents compared with their exposition to Sirinol, Palizin and Tondexir alone and control. The results highlighted that the combination of Sirinol, Palizin and Tondexir had better effects on granary weevil compared to their individual use.
