Abstract: Dengue and chikungunya are deadly diseases transmitted by Aedes aegypti. Essential oil a natural product contains highly volatile chemical compounds and use as a personal protection against blood sucking mosquito is an effective and safe method. The objective of these studies was to evaluate the synergistic effect of 10 effective oils with the help of K & D module and Electroantennogram (GC-EAD). In the study of protection period, litsea + rosewood in the ratio of 1:1 (v/v) at 10% concentration showed 86% repellency for 4 hours against Ae. aegypti using K & D module. In the study of electrophysiological experiment, p-Menthane (4.13RT), Citronellol (4.25RT), Z-Citral (4.41RT), Citral (4.57RT) from the blend of ten selective essential oils showed strong antennal responses on the receptors of Ae. aegypti. In the present study, essential oil showed effective result are useful for developing safe, biodegradable, eco-friendly and effective insect repellent.
