With the crisis and the increase in agricultural pests, there was a need for evolution in the correct management of insects in major crops. Biological control provides for the use of natural inputs as toxicological agents against existing enemies in organic farming. In this way, the use of botanical insecticides regulates the natural balance of species. To obtain new methods of control and management, essential oils were used to eliminate aphids present in cabbage specimens, thus allowing the continuity of vegetable production away from pests. In this study, we will be able to evaluate the viability of different vegetable oils as natural insecticides on aphids of cabbage. It was concluded that the mortality rate showed 100% efficiency on aphids at concentrations of 10%, 25%, 50% and 100% in the different oils tested. According to what was observed, the mortality time showed that Mauritia flexuosa obtained the shortest time as being the best to kill the aphids, followed by the other oils. It is worth noting that for use on leaf specimens, only the concentrations 10% and 25%, regardless of the oils, offered no commercial damage.
