Abstract
Medicinal plants have been developing as the main material for botanical pesticides. Many medicinal plants can be used as botanical pesticides due to their effectiveness in controlling the pest. This study aims to examine the potential of Eucalyptus citriodora and Artemisia vulgaris against Sitophilus zeamais, which can be used to control the storage pest using these plants without using synthetic pesticide. This study was conducted in the pest laboratory, Indonesian Spice and Medicinal Crops Research Institute (ISMCRI), from January to February 2021. The formula of two essential oils of E. citriodora and A. vulgaris with different concentrations (1.5%, 2%, 2.5%, and 3%) were used to control S. zeamais. The result showed that the A. vulgaris had the most potent efficiency as a botanical pesticide against S. zeamais. The highest mortality values of imago S. zeamais at 72 hours after applying E. citriodora and A. vulgaris were 90% and 93%, respectively. Artemisia vulgaris has the highest reaching repellent percentage of imago S. zeamais its 85% at 1 hour after application for 3% concentration. Indicates that essential oils, E. citriodora, and A. vulgaris, possess insecticidal activity against S. zeamais.
