Abstract

Objective: To evaluate the mosquito repelling effects of four plant essential oils. Methods National standard method was adopted to test the mosquito repelling effects of four plant essential oils. Response surface methodology was used to analyze the optimum ratio of the essential oils.

Results: The repellent effects ranked as follows:

Chrysanthemum oil>Calendula oil>Holly oil>Anise-star oil. And the synergistic effects were regarded with the combination of chrysanthemum and calendula oil. The mosquito repelling effect was up to (93.33±2.57)% when 50μL chrysanthemum oil and 18.49μL calendula was mixed together in the 0.075m3 cylinder.

Conclusion: The four plant essential oils all have good mosquito repelling effect and show synergism when they are mixed
