Objective: The aim of this work was to evaluate the acaricidal potential of the passion fruit seed extract (Passiflora edulis) in controlling the red palm mite (R. indica). Theoretical framework: Raoiella indica is a pest mite of agricultural interest, considered one of the main pests of banana, coconut, date palm, and ornamental crops. Method: The experiment was conducted in a completely randomized design using passion fruit seed extract, with 7 repetitions and 12 R. indica individuals per repetition. The concentration tested was 1.0; 1.72; 2.95; 5.08; 8.73, and 15.0 %. The experimental units consisted of coconut leaf discs (4 cm in diameter) with moist cotton at the bottom of the Petri dish (10.0 x 1.2 cm) and around the disc to maintain turgidity and prevent the mites from escaping. The application was carried out using an airbrush, connected to a compressor calibrated with a constant pressure of 1.3 psi and 1 mL of solution per plate. The evaluation was conducted at intervals of 24, 48, and 72 hours following the extract's spraying. Results and discussion: Mortality was observed in the dose-response model, the concentration of 15 % showed mortality rates greater than 98.8 % of individuals. Amounts of phenolics of 10.242, tannins of 14.837, and flavonoids of 9.700 in mg g^-1 were found, attributing the mortality of individuals to the presence of these compounds. It was concluded that the passion fruit seed extract has an acaricidal effect on R. indica in the laboratory. Implications of the research: Alternative pest management has grown substantially in recent years, given the demand for more sustainable products in the agricultural field. The use of botanical extracts is beneficial to the environment, as it does not promote soil and water contamination and can be an efficient method for controlling agricultural pests. Originality/value: This article adds value to research areas such as alternative management of agricultural pests, and sustainability and suggests a change in the environmentally conscious behavior of rural producers.

Purpose: Therefore, this study aimed to use the crude extract of Eruca vesicaria (arugula) leaves in the management of Raoiella indica. Theoretical reference: The red palm mite is an invasive species and is considered a pest of great importance for coconut and banana trees and other plants in the Arecaceae family. Therefore, this study aimed to use the crude extract of Eruca vesicaria (arugula) leaves in the management of Raoiella indica. Method: For this, fine powder from arugula leaves was used diluted in water and Tween® adhesive spreader, in concentrations of 1.0; 1.58; 2.51; 3.98; 6.31, and 10.0 %. These extracts were sprayed on 10 adult females of R. indica per sample unit, with 10 replicates for each concentration. The acaricidal effect was evaluated at different time intervals after spraying: 12, 24, 36, 48, 60, and 72 hours. Results and conclusion: The results demonstrate that mortality of the R. indica mite increases as the concentration of arugula vegetable extract increases, with lethal concentrations above 3.98 % being indicated for control. Research implications: The aqueous arugula extract, in its different concentrations, demonstrated acaricidal efficacy against the red palm mite under laboratory conditions. Originality/value: This text adds value to fields of study such as alternative insect control in crops and sustainability, proposing a change in the ecologically responsible behavior of farmers.

Purpose: This study aimed to evaluate the acaricidal potential of the aqueous extract obtained from the ripe peels of Citrus limon on adults of Raoiella indica. Theoretical Reference: R. indica is a phytophagous mite that primarily attacks plants of the Arecaceae family. As it is considered a relatively new pest in Brazil, there are few control methods available, with synthetic chemical control being the primary one. Method: The ripe peels of C. limon were dried and ground into a fine powder, which was used to formulate extract concentrations of 0.00, 1.00, 1.64, 2.70, 4.44, 7.30, and 12.00%. The extracts were sprayed on 12 adult females of R. indica per experimental unit, with 7 repetitions for each concentration. Mortality was assessed at 24, 48, and 72 hours after spraying. Results and Conclusion: The mortality of R. indica increased as the concentrations of the ripe peel extract of C. limon increased, reaching 88% for the highest concentration after 72 hours of application. Research Implications: The aqueous extract of ripe peels of C. limon demonstrated acaricidal efficiency against R. indica under controlled conditions. Originality/Value: This work adds value to the study of alternative methods of agricultural pest control, as a means of promoting more economically and ecologically sustainable management.

The pink mealybug, Maconellicoccus hirsutus (Green) (Hemiptera: Pseudococcidae) is a polyphagous pest species that has been reported in about 350 species of host plants worldwide. Usually, the use of synthetic chemicals is still the most used control method for the control of agricultural pests. The objective of this present work was to evaluate the potential of the interaction of oils extracted from the species Ricinus communis L. (castor) and Jatropha curcas L. (jatropha) (Euphorbiaceae) in the form of direct and indirect application on M. hirsutus. The experiments were conducted in air-conditioned chambers at a temperature of 25 ± 1ºC, relative humidity 70% ± 10 and a photophase of 12h. The 3% concentration was used in the tests, with 11 interaction ratios between the oils. Individuals' mortality was assessed at 24, 48 and 72 hours after spraying. The results of the interactions indicated up to 78% mortality of individuals in the ratio 90% castor + 10% jatropha via indirect application, while in the direct application on individuals they presented 53% mortality in the ratio 40% castor + 60% jatropha. The interactions between castor and jatropha oils have demonstrated potential in the management of pink mealybug by direct or indirect application.

Embora os inseticidas químicos sejam usados ​​com sucesso na agricultura, vários problemas podem estar relacionados ao seu uso indiscriminado. Isso tem incentivado o desenvolvimento de métodos alternativos para o controle de pragas e insetos, bem como a pressão social por produtos livres de pesticidas. A jatropha (J. curcas) e a mamona (Ricinus communis) são plantas que apresentam potencial inseticida. Assim, o objetivo deste trabalho foi estudar folhas de J. curcas e R. communis de diferentes idades sobre o pulgão-da-couve (Myzus persicae). Foram utilizadas cinco concentrações de solução e cinco tipos de folhas. Cada tratamento consistiu de dez indivíduos M. persicae, mantidos em placas de Petri (10,0 x 1,2 cm), sobre discos de folhas de couve. Cada placa de Petri foi considerada uma repetição, totalizando dez. Para aplicação direta, utilizou-se um aerógrafo conectado a um compressor calibrado a pressão constante e 5 mL de solução por repetição. Na aplicação indireta, os discos de repolho foram imersos por cinco segundos nos diferentes tratamentos e oferecidos aos pulgões. Para ambos os testes, as avaliações foram realizadas 72 horas após a aplicação. Os dados foram submetidos à análise de regressão linear e teste de médias. Para ambas as plantas houve interação entre o tipo de aplicação, tipo de folha e concentrações. Reiteramos que as folhas de pinhão-manso e mamona, em suas diferentes idades, apresentam potencial inseticida no manejo de M. persicae.
