dc.descriptionSeveral species of predatory mites, naturally occurring in coconut plantations, play an important role in regulating populations of phytophagous mites that are key pests of this crop. Plant essential oils (EOs) are bioactive mixtures of compounds that hold potential for controlling phytophagous arthropods with minimal impacts on non-target organisms and the environment. This study aimed to characterize the chemical composition and assess the bioactivity of the EO extracted from the leaves of the ?Pera? sweet orange grafted on ?Rangpur lime? to a key pest of coconut plantations worldwide, namely the coconut mite Aceria guerreronis (Acari: Eriophyidae), and its compatibility with the naturally-occurring generalist predatory mite Typhlodromus ornatus (Acari: Phytoseiidae). Briefly, sabinene was the major component, followed by &#948;-3-carene and (E)-&#946;-ocimene. The EO was toxic to A. guerreronis (LC50 = 4.28 mg/mL; LC80 = 10.39 mg/mL) but not to T. ornatus. The LC80 of the EO did not repel A. guerreronis and was toxic to the pest mite only in the first hours (<9 h). Moreover, this concentration did not affect the growth rate of the predator, which was positive over the 10 days of exposure to the oil. Therefore, the EO of ?Pera? sweet orange holds potential for the management of coconut mite and is compatible with the generalist predatory mite T. ornatus.
