Abstract: Vector of the main arbovirus in the world, Aedes aegypti is an exponential threat in the development of the human species. The control tactics currently used focus on the detection and mechanical destruction of mosquito oviposition foci by health and population agents, in addition to the application of chemical insecticides. However, these commonly used substances, due to the high degree of toxicity and low selectivity, are responsible for direct damage to the environment. Furthermore, in view of recurrent annual epidemics in Brazil and the growing number of cases in the world, the existence of a gap in the management of this culicid is evident. In this context, the search for less harmful alternatives led to the possible use of essential oils and/or their constituents in the management of this insect, in view of its biodegradable, selective properties and the wide range of toxicological, repellent, larvicidal, proven cytotoxic. Given the above, we sought to evaluate works from a physiological perspective, on how these molecules, whether chemical or biological, interact with the insect's organism. A bibliographic search was carried out on online platforms, using keywords and limited to scientific works carried out in the last 15 years. 21 articles were selected for reading. After this survey, it is possible to infer that structural alterations in the digestive physiology of Ae. aegypti from the action of essential oils and their major compounds, are capable of harming the insect's life cycle, as a result of lagged nutrition, as well as directly reflecting on its reproductive aspects, leading to its death. Although this is also observed in work with chemical insecticides, the development of resistance mechanisms to these substances is increasingly recurrent, in addition, from a socio-environmental point of view, they are highly harmful. Therefore, essential oils are promising biomolecules in the fight against the mosquito vector of arboviruses, Ae. aegypti.
