Abstract:
The objective of this study was to compare the efficiency of 10 percent eucalyptus oil (Eucalyptus camaldulensis) in 5 different solvents composed of hexane, xylene, acetone, propanol and methanol to repel maize weevil, Sitophilus zeamais using alternative test method on a Petri dish with a lid. The result found that the maize weevil was repelled by eucalyptus oil in all solvents ranged from 86.7 - 100.0 percent at 2 - 24 hours and not a significant difference. The repellent efficacy of eucalyptus oil dissolved in acetone at the concentration of 10 percent was ranged from 95.0 - 100.0 percent from 2 - 24 hours. The contact toxicity of eucalyptus oil dissolved in acetone determined by median lethal concentration (LC50 and LC99) at 6 hours was 26.08 and 36.74 percent (v/v).
