Abstract : In the Campeche state, México, thrips species in mango and their population fluctuations are unknown which difficult their control causing losses in production and fruit quality; thus, the objective of this study was to determine the thrips associated with the crop, their population fluctuation and the level of damage. Research was carried out during 2009 and 2010 in Castamay, Campeche, Mexico. Samples were taken of the adults and nymph's population every 15 days in foliage and inflorescences and the level of damage to the fruit was determined. Thrips population was correlated with precipitation and temperature variables using the Pearson coefficient and ?2 tests were performed between thrips population and sampling dates. In 2009, the lowest population was 0.00 and 0.13, the highest per leave in both nymphs and adults. In 2010, the lowest populations were 0.00 individuals per leaf for both nymphs and adults and the highest of 0.15 adults per leaf and 0.35 nymphs per leaf. The observed damage levels were low and showed no significant influence on fruit production. Four thrips species associated with mango, all phytophagous were found Heliothrips haemorrhoidalis, Frankliniella invasor, Scirtothrips perseae and S. hectorgonzalazi. The population fluctuation was not significantly correlated with climatic variables.
