dc.descriptionGenipap (Genipa americana L.) is a medicinal tree native to South America and the Amazon regions, where it is used as a popular traditional medicine. It is also highly consumed by people in the form of jams, juices, preserves, and wines. The aim of this study was to evaluate the toxicity, persistence, and the repellence properties of leaf methanolic extracts of genipap (LME) and its major iridoids (genipin and geniposide), against the key coconut pest mite Aceria guerreronis Keifer. The concentration-mortality bioassays revealed a strong acaricidal activity of LME against the coconut mite (LC50 = 0.60 mg.ml-1; and LC90 = 16.69 mg.ml-1). In addition, standard concentrations (0.6 mg.ml-1) of either genipin or geniposide killed 50 % and 62 % of the A. guerreronis, respectively, after 24 hours of exposure, highlighting the role of these iridoids in the acaricidal activity of LME. The persistence bioassays of LME revealed toxicity towards A. guerreronis for up to 36 hours after spraying. Furthermore, LC50 and LC90 of LME repelled the coconut mite after 1, 24, and 48 hours of exposure. Therefore, LME can be considered an alternative to assist in the integrated control of the coconut mite in coconut plantations.
