| Genipap (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.... |

| Several species of predatory mites, naturally occurring in coconut plantations, play an important role in regulating populations of phytophagous mites that are key pests of this crop. Plant essential oils (EOs) are bioactive mixtures of compounds that hold potential for controlling phytophagous arthropods with minimal impacts on non-target organisms and the environment. This study aimed to characterize the chemical composition and assess the bioactivity of the EO extracted from the leaves of the ?Pera? sweet orange grafted on ?Rangpur lime? to a key pest of coconut plantations worldwide, namely the coconut mite Aceria guerreronis (Acari: Eriophyidae), and its compatibility with the naturally-occurring generalist predatory mite Typhlodromus ornatus (Acari:... |

| Genipa americana L. has a diversity of secondary metabolites, including iridoids, phenolic compounds, and alkaloids. Pharmacological and biological properties have also been reported. This study has aimed to evaluate the chemical composition of the essential oil (EO) obtained from the leaves of G. americana and its bioactivity against Aceria guerreronis Keifer (Acari: Eriophyidae), a serious pest of coconut production areas worldwide. EO from the leaves was extracted and analyzed by Gas Chromatography-Mass Spectrometry and flame ionization detection (GC-MS/FID). For the bioassays, the adult coconut mites were subjected to increasing concentrations of EO. The analyses showed a predominance of sesquiterpenes, followed by monoterpenes, aldehydes, and fatty... |
