| dc.description.resumo | Arboviruses are among the main public health problems in Brazil. Aedes aegypti is the main vector of some of the most common diseases, such as dengue fever, for example. The efficient option to reduce the incidence of arboviruses is vector control. To investigate more effective substances with less environmental impact to control Ae. aegypti, this research investigated the larvicidal potential of P. cattleyanum volatile oil, evaluating the influence of seasonal variation in chemical composition and its bioactivity. P. cattleyanum leaves were collected between May/2021 to April/2022 and subjected to hydrodistillation to obtain the volatile oil. The samples obtained were chemically characterized and grouped according to similar composition. The bioactive potential of the pooled samples was tested against Ae. aegypti larvae in third instar. The main components observed in the volatile oil were 1,8-cineole and β-caryophyllene. It was observed a higher percentage of monoterpenes in dry periods (cluster I) and in rainy periods (cluster II) a predominance of sesquiterpenes. Greater larvicidal potential was observed in samples with a predominance of monoterpenes. These results showed that the volatile oil of P. cattleyanum has larvicidal potential against Ae. aegypti variable depending on the meteorological condition. This information is useful for planning new studies. | |
