“…The first report in Brazil occurred in 1950 in coffee tillages in the state of São Paulo (TOLEDO et al, 2018). In the state of Espírito Santo, O. ilicis is considered the second biggest pest of the Conilon coffee, Coffea canephora (Pierre & Froehner, 1897) (Rubiaceae) (Franco et al, 2021;Gomes et al, 2023).…”

The coffee red spider mite, Oligonychus ilicis, stands out as one of the main pests of Conilon coffee. The use of synthetic chemical control has led to an increase in the population of this mite and a reduction in its natural enemies. Aiming to find viable alternatives, this study aimed to evaluate the acaricidal potential of “abricó” peel extract, Mammea americana, in the management of O. ilicis. Each treatment consisted of 7 repetitions, with 10 individuals per repetition. They were placed in Petri dishes (10.0 x 1.2 cm), containing coffee leaf disks (4 cm diameter) inside, and moistened cotton at the bottom of the dish and around the disks. The peels of M. americana were dried, crushed, and diluted in aqueous solution to obtain extracts at concentrations of 2; 2.57; 3.30; 4.24; 5.45; and 7 %. The application was done by spraying, using an Alfa 2 model airbrush connected to a compressor calibrated with a constant pressure of 1.3 psi. 1 mL of solution of each concentration was applied for each repetition. Distilled water and the surfactant Tween® 80 (0.05 % v/v) were used as control treatments. The acaricidal effect was evaluated 24, 48, and 72 hours after spraying, and the lethal concentrations LC50 and LC90 were calculated. The results of the toxicity tests indicated an increase in the mortality of O. ilicis with the increase in the concentrations of aqueous extracts of M. americana, resulting in 100 % mortality. The LC90 was estimated at 3.83 %. In the chemical analysis of the M. americana extract, the presence of phenolic acids, tannins, and flavonoids was observed at concentrations of 39.150, 40.783, and 0.0349 mg-1, respectively. We conclude that the aqueous extract of M. americana peels demonstrated acaricidal potential in a controlled environment for the coffee red spider mite.

“…De acordo com Franco et al (2009), esse ácaro vive na parte adaxial das folhas e se alimentam do conteúdo celular extravasado proveniente da perfuração que faz nas células da epiderme e do mesófilo. Em ataques intensos, reduz o potencial fotossintético da planta as fazendo perder o brilho natural de suas folhas e são recobertas por teias onde se aderem poeiras, detrito e suas exúvias.…”

O ácaro Oligonychus ilicis, conhecido como ácaro vermelho do café, é considerado uma praga de grande importância para a cultura cafeeira devido ao seu hábito alimentar, que causa danos significativos às folhas das plantas. Com o objetivo de controlar essa praga, o experimento avaliou o potencial acaricida do extrato de Eugenia stipitata. Para isso, foram coletados frutos em estágio de pré-maturação que foram submetidos a um processo de secagem e moagem até a obtenção de um pó fino que, posteriormente, foi diluído em água e adicionado de espalhante adesivo Tween® 80 (0,05% v/v) para melhorar a eficácia da pulverização. As concentrações utilizadas foram de: 0,50; 0,848; 1,437; 2,436; 4,129; 7,0. Cada concentração foi aplicada em 6 repetições que continham 10 fêmeas adultas do ácaro. Em seguida, foram pulverizadas sobre cada repetição 1ml de solução. A avaliação do efeito acaricida foi realizada 12, 24, 36, 48 e 72 horas após a pulverização. Observou-se que à medida que se aumentava a concentração, aumentou a mortalidade de O. ilicis.

“…The chemical management of coffee pests and diseases has been related to the considerable red mite population increase due to the adverse effect on natural enemies, the selection of organisms resistant to chemical molecules, as well as the pest's oviposition stimulus (REIS et al, 2005;FRANCO et al, 2009), requiring the development of alternative pest control programs, such as the use of natural extracts (TOLEDO et al, 2018).…”

The coffee red mite, Oligonychus ilicis, is an important pest for Conilon coffee, Coffea canephora. This study aimed to evaluate the acaricidal potential of Citrus aurantifolia and Citrus latifolia peels hydroalcoholic extracts against O. ilicis. The citrus peel extracts at concentrations of 0.10, 0.17, 0.30, 0.51, 0.87, and 1.50 % w v-1 were sprayed on O. ilicis and its mortality was evaluated. Data were subjected to Probit analysis (p≤0.05) with the R statistical software and the LC50 and LC90 were calculated. O. ilicis mortality was dose-dependent on the concentration of the citrus peel hydroalcoholic extract. The slope coefficients of the O. ilicis mortality curves as a function of the concentration of extracts were 2.6057 and 1.4498 for C. aurantifolia and C. latifolia extracts, with LC50 and LC90 of 0.173 and 0.537% w v -1, for the first, and 0.048 and 0.368% m v -1, for the second, respectively. C. latifolia presented more phenolics and tannins in its composition than C. aurantifolia. C. latifolia and C. aurantifolia extracts showed an effective acaricide effect against O. ilicis, being a promising alternative for coffee red mite management.
