Eruca Vesicaria (Arugula) Extract: Possible Acaricidal Effect Against Red Palm Mite

Abstract

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.
