Mosquito Repellent Efficacy of Australian Blue Cypress Callitris intratropica Essential Oil and a Topical Formulation under Laboratory and Field Conditions.

ABSTRACT: Mosquito repellents are important for personal protection against nuisance and potentially infectious mosquito bites. Repellent activity of Australian blue cypress essential oil (EO) and a commercially formulated skin lotion containing blue cypress EO (topical formulation) were compared with 20% DEET (N, N-diethyl-3 toluamide) against mosquitoes under laboratory and field conditions in North Queensland, Australia. On a volunteer's forearm, 1 mL of candidate material was applied to approximately 600 cm2 of exposed skin. When blue cypress EO was applied at various concentrations (0.5%-10.5%), it did not fully prevent mosquito landing or biting. However, a dose-dependent increase, approaching 80% protection, was observed at high EO concentrations. On the basis of these results, three concentr
