  • Essential oils of O. basilicum and E. globulus were tested for their volatile toxicity in the laboratory against sawtoothed beetle, O. surinamensis. The concentrations of 4.0, 8.0, 16.0, and 32.0 μl/l air were used in the volatile toxicity experimental. The results indicated that O. basilicum was highly toxic than E. globulus. The results indicated that increased concentration of different oils and exposure time leads to increase in the percentage of mortalities. Also, in storage experimental, the toxic activity for the tested oils was investigated. Ocimum basilicum protects dry dates in storage for 3 months from Surinam beetle infestation.
