Antifeedant, insecticidal and growth inhibitory activities of selected plant oils on black cutworm, Agrotis ipsilon (Hufnagel) (Lepidoptera: Noctuidae)

To evaluate antifeedant, insecticidal and insect growth inhibitory activities of eucalyptus oil (Eucalyptus globules) and gaultheria oil (Gaultheria procumbens L.) against black cutworm, Agrotis ipsilon. Antifeedant, insecticidal and growth inhibitory activities of eucalyptus oil and gaultheria oil were tested against black cutworm, A. ipsilon. Significant antifeedant activity was found in eucalyptus oil (96.24%) where as the highest insecticidal activity was noticed in gaultheria oil (86.92%). Percentages of deformities were highest on gaultheria oil treated larvae and percentage of adult emergence was deteriorated also by gaultheria oil. These plants oil has potential to serve as an alternative eco-friendly control of insect pest.
