| Additional Information: | Diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), is the dominant insect pest of cruciferous crops around the world. The chemical treatment for controlling this insect pest is ineffective and eventually lead to invironmental pollution. Plant and plant derived materials appear nowadays as a safe alternative to conventional pesticides to fight against crop pests. Use of plant extracts in pest management has gained momentum during the past decade. Essential oils have been reported to possess multiple pest control properties like toxicity, repellency, feeding deterrence and oviposition deterrence. This research was conducted to determine the effect of essential oils such as eucalyptus oil, vetiver oil, cinnamon oil, and kaffir root oil on repellency for adult insects of Plutella xylostella L, oviposition deterrent of adult female and repellency of instars larvae of Plutella xylostella. The research was carried out from January to March 2020 at the Entomology and Phytopathology Laboratory of the Lembang Bandung Vegetable Research Institute. All bioasseys were conducted under controlled environmental condition (27 ±2º C and 75-80% RH). Three bioassays were conducted. The first assay was conducted to the effect of essential oil on repellency of Plutella xylostella adult. The second assay was conducted to determine effect of essential oil on oviposition deterrent of adult female, Plutella xylostella. The third assay was conducted to determine the effect of essential oil on repellency of instars larvae of Plutella xylostella. The experiment was arranged in used a completely randomized with five treatments including control and four replication. The results showed that the Kaffir root oil has highest reaching reppelent percentage of imago P. xylostella its 24 % at 24 hours after application. Oviposition deterrent of P. xylostella on all treatments showed the percentage of all essential oils more than 36 % and not significantly different from the results of statistical tests, where the essential oil of kaffir root oil has the highest value of percentage of oviposition deterrent reaches 54,18 %. Eucalyptus oil treatment on the observation of P. xylostella larvae repellent showed the highest percentage 79% at 6 hour after application. The benefit of this research is that it can add information about the ability of essential oils from eucalyptus, vetiver, cinnamon, and kaffir lime as a source of insecticides that can be used safely, cheaply, and environmentally in an effort to control pests.
