Ceratitis capitata (Wiedemann) causes significant economic losses to Brazilian fruit crops. In this context, and given the need to develop sustainable strategies for controlling this pest, the study of the insecticidal potential of essential oils has gained worldwide prominence. Thus, this study aimed to evaluate the effectiveness of the essential oils of Carapa guianensis Aublet, Cymbopogon winterianus Jowitt, and Eucalyptus citriodora Hook in the mortality and emergence of C. capitata in two life stages. The research was conducted at the Entomology Laboratory of the Agricultural Sciences Center at the Federal University of Paraíba, Brazil. The essential oils used were derived from commercial formulations. For each type of oil, 3rd instar larvae and pupae were immersed in five concentrations. The action of the oils varied depending on the life stages in which they were applied, and their effects were more pronounced during the initial hours post-application. The use of C. guianensis oil, when applied during the pupal stage at a concentration of 37.6 mg.ml⁻¹, resulted in 75% mortality of individuals (LD75). For larval applications, E. citriodora oil stood out, producing the highest larval mortality rates and greater persistence of action. The use of essential oils in the control of C. capitata proved to be a promising alternative, but attention should be given to the life stage and applied concentrations to optimize the success of this control method.
