摘      要：Objective: To evaluate an essential oil with larvicide, adulticide and growth inhibitory activity against Aedes aegypti, Aedes albopictus and Culex quinquefasciatus mosquitoes, of medical importance. Methods: Standardized methodology by WHO was used to determine the levels of susceptibility of mosquito larvae exposed to the essential oil. To evaluate the adulticide activity with the essential oil at different doses, bottles were impregnated according to the methodology CDC. To determine the development inhibitory activity of Melaleuca quinquinervia(M. quinquinervia) oil in three mosquito species, third instar larvae were exposed to the LC_(50) and LC_(90) dose(calculated for each population) of M. quinquinervia oil in glass containers with a capacity of 500 mL. After 24 h exposure, the dead larvae were discarded. The mortality of larvae and pupae were recorded on a daily basis. Results: The calculated LC_(50) indicates an order of effectiveness of preferential oil for Culex quinquefasciatus(LC_(50)=0.002 1%), Aedes aegypti(LC_(50)=0.004 7%) and Aedes albopictus(LC_(50)=0.004 9%). Conclusions: The adulticide activity was achieved with impregnated bottles at 40 and 50 mg/mL with the three mosquitoes species. In larvae, a growth inhibition was detected when exposed to sublethal doses. The results indicate that M. quinquinervia is a plant with promising environmentally sustainable source for vector control.
