Pest control using essential oils is considered safer and environmentally friendly. Essential oils used in this study are A. nardus, E. globulus, and M. piperita. It made nanoemultion to reduce evaporation. This research aims to analyze the insecticidal activity of chlorpyrifos and the three types of essential oils as well as their repellent to adult Callosobruchus maculatus (F.). The research method consists of sample preparation, manufacture nanoemultion of essential oils, mortality test, and repellent test. The results showed that the pesticide chlorpyrifos has high insecticidal percentage compared with essential oils, but its use is not environmentally friendly. However, all the encapsulated essential oils in this study has potential to be used as a environmentally friendly pesticides to control the insect pest Callosobruchus maculatus (F.).
