Acaricidal activity of plant extracts against the red palm mite Raoiella indica (Acari: Tenuipalpidae)

The red palm mite Raoiella indica Hirst has recently invaded the Neotropical region, which demands implementation of pest management strategies. In this study, toxicity leaf extracts Mexican oregano Lippia berlandieri Schauer, neem Azadirachta A. Juss, mint Plectranthus amboinicus (Lour.) Spreng., rue Ruta graveolens L. and Persian lime Citrus x latifolia Tanaka against R. was evaluated under laboratory conditions. females were exposed to each plant extract at concentrations 0.25, 0.50, 0.75 1% (v/v) assess cumulative mortality 24, 48 72 h after exposure. Mortality rates rose due increased concentration exposure time. strongest acaricidal activity observed with berlandieri, P. amboinicus, whose caused a mean 100, 90 78%, respectively. These hold promise for chemical
