    In this work, the lethal and ovicidal effect of garlic and soursop vegetable oils and the isolated compound d-limonene and formulations based on these oils on adults of Tetranychus urticae and their eggs were evaluated. For the preparation of the formulations using the aforementioned oils as the active ingredient, the addition of adjuvant agents with encapsulating and emulsifying properties was carried out, in order to enhance the effects of these oils on adults and eggs. The oils and formulations tested to evaluate lethal activity were diluted in concentrations at 0.1%, 0.2%, 0.4%, 0.6%, 0.8% and 1.0% (v/v) and sprayed directly on the adult mites. Dilutions of 0.1%, 0.2%, 0.4% and 0.6% (v/v) of the oils and their respective formulations were prepared to attest to the ovicidal effect and applied to T. urticae eggs. For the only diluted oils, a high acaricidal potential of garlic oil was observed, which in lower concentrations was considerably effective. The formulations showed promise in the face of increased mite mortality for all phytochemicals used and at all concentrations. Regarding the ovicidal effect, garlic and soursop oil at concentrations of 0.4% and 0.6% (v/v) showed significant potential, making the treated eggs unviable, reaching hatching rates below 20%. As for the formulations, they proved to be more effective in this bioassay, when compared to the pure bioactives, making it impossible to develop and hatch eggs in lower concentrations and for the three treatments
