The objectives of this study in late 2008 to 2010 at San Antonio Cayal, Campeche, Mexico, were to determine the thrips species associated with inflorescences and leaves and the fluctuation of thrips in abundance on mango, Mangifera spp. Four species of thrips were found in inflorescences and two species in foliage. The phytophagous species of thrips Heliothrips haemorrhoidalis Bouché, Frankliniella Invasor Sakimura, Frankliniella occidentalis Pergande, and Frankliniella sp. (undescribed), and the predator mites Leptothrips macconeli (DL Crawford), and Leptothrips macro-cellatos Wakson were observed. Abundance of nymph and adult thrips per leaf ranged from 0.0 to 0.33 on several sampling dates, with 0.14 adults per leaf during the month of May. In 2010 zero adult and nymph thrips were recorded as in 2009 on several sampling dates, with most nymph and adult thrips per leaf (0.05 each) found in the month of April.
