“…According to Esteves Filho et al ., given the general recommended concentration of 1% (10 mL L −1 ) for botanical acaricides, the high toxicity of these products also becomes evident at the lethal concentrations in the present study. This performance is very important for the integrated management of P. latus , considering the several advantages of natural products over synthetics.…”

“…The fixed oils of J. curcas and R. communis were obtained by cold pressing. Subsequently, the oils were filtered and treated with emulsifier (Esteves Filho et al, 2013). The eugenol standard synthetic compound (98% purity) was purchased from Sigma-Aldrich (St. Louis, MO, USA).…”

-The objective of this work was to assess the fumigant and repellent effects of essential oils on adults of Callosobruchus maculatus and to identify the chemical composition of two of the tested essential oils. For the fumigation test, the oils of Schinus terebinthifolius, Piper aduncum, Syzygium aromaticum, Piper hispidinervum, Cymbopogon citratus, Cinnamomum zeylanicum, and the eugenol compound were tested at different concentrations on C. maculatus adults. For the repellency test, the oils of S. terebinthifolius, P. aduncum, P. hispidinervum, S. aromaticum, Jatropha curcas, and Ricinus communis were evaluated. In the fumigation test, it was observed that P. aduncum and eugenol showed the highest and lowest LC 50s , of 169.50 and 0.28 µL L -1 air, respectively. In the repellency test, the oils of S. aromaticum and P. hispidinervum were repellent to C. maculatus. Gas chromatography coupled to mass spectrometry (GC-MS) analysis of these two oils identified 42 compounds, of which safrole was the main component of P. hispidinervum and eugenol of S. aromaticum. The essential oils of S. aromaticum, C. zeylanicum, and the eugenol compound are the most promising to control C. maculatus, via fumigation.

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

et al. 2021

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