Abstract Content

Botanical derivatives that influencing mosquito larvae development could be ecofriendly alternative for the synthetic insecticides. The present work investigated effects of two sub-lethal concentrations of Cinnamon (Cinnamomum cassia) and Wintergreen (Ilex chinensis) volatile oils on the development of Aedes aegypti mosquito larvae under laboratory conditions. Bioassays were carried out according to WHO methodology. Observations of larval mortality, pupal mortality, adult emergence, sex ratio, and malformations were recorded over 14 days. Results indicated growth and/or molting disrupting effect of such oils against larvae and their efficacy was plant species and dose dependent. Cinnamon oil outperformed wintergreen oil by reducing adult emergence to 16%. Although this study confirmed that this oil as a promising candidate for the development of new botanical-mosquitocide having multiple potentials for controlling Ae. aegypti to reduce mosquito bites and mosquito borne disease but further studies such as field evaluation are required.
