Raoiella indica Hirst (Acari: Tenuipalpidae), the red palm mite, is a phytophagous mite that recently invaded the Western Hemisphere. This mite was first detected in Martinique (Flechtmann & Etienne 2004) and it rapidly spread to multiple islands of the Caribbean [St. Lucia and Dominica (Kane et al. 2005), Guadeloupe and Saint Martin (Etienne & Flechtmann 2006), Puerto Rico and Culebra Island (Rodrigues et al. 2007), and Cuba (de la Torre et al. 2010) among other islands]. In 2007, the mite was found in West Palm Beach, Florida (FDACS 2007), and in the state of Sucre, Venezuela (Vasquez et al. 2008), and more recently, reported in the northern state of Roraima in Brazil (Marsaro Jr. et al. 2009), and Isla Mujeres and Cancun, Mexico (NAPPO 2009). In January 2010, high populations of R. indica were found attacking coconut (Cocos nucifera L.), banana (Musa acuminata Colla) and heliconia (Heliconia sp.) plants in the Tayrona National Park located in the Colombian Caribbean littoral, near the city of Santa Marta, Magdalena. The presence of multigenerational colonies and exuvia was confirmed in 18 coconut palms, 4 heliconias and multiple banana plants located near the coast in the northern part of the park (11[degrees]18'44"N 73[degrees]56'04"W). In further surveys R. indica infestations were detected in commercial coconut and banana groves in June 2010 at Los Naranjos, Magdalena (11[degrees]17'49"N -73[degrees]53'49"W), approximately 6 km East of the Tayrona Park along the coast. In this locality the predatory mite Amblyseius largoensis Muma (Acari: Phytoseiidae) was found showing a conspicuous red coloration of the alimentary tract indicating recent feeding on R. indica. Previous studies indicated that populations of A. largoensis increased in numbers after the arrival of R. indica to Florida and some areas in the Neotropics (Pena et al. 2009; Carrillo et al. 2010).
