Bioactivity of essential oils for the management of Tetranychus urticae Koch and selectivity on its natural enemy Neoseiulus californicus (McGregor): A promising combination for agroecological systems

The two-spotted spider mite, Tetranychus urticae, causes damage to crops grown in northeast Brazil. adoption of biological control methods and curative (plant-based insecticides) is an essential practice for pest management agroecological systems. Therefore, the aim present study was investigate chemical properties, toxicity, ovicidal activity oils (EOs) from Lippia sidoides, Croton rhamnifolioides, grewioides, Citrus sinensis, limon, aurantiifolia Piper divaricatum T. urticae determine selectivity these EOs regarding predator mite Neoseiulus californicus. analysis (gas chromatography–mass spectrometry) enabled identification 98 compounds. major constituents were carvacrol (L. sidoides), ?-caryophyllene (C. rhamnifolioides), (E)-anethole grewioides), limonene (Citrus spp.), safrole methyl eugenol (P. divaricatum). All exhibited satisfactory toxicity eggs females even more toxic than commercial product Azamax. L. sidoides oil greater compared other oils, with LC50 values 0.05 0.09 µL mL-1 eggs, respectively. tested selective N. californicus, RS ranging 3.61 23.28 C. use products based on studied combination natural enemy californicus a viable option systems urticae.
