Efficiency of Citrus limon L. Ripe Peel Extract In The Control of Raoiella indica (HIRST, 1924) (Prostigmata: Tenuipalpidae)

Abstract

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.
