Abstract : In the state of Campeche, Mexico, mango and sweet orange are important fruit crops; however, fruit commercial trade is affected by a high incidence of the fruit fly complex. A study was conducted at eight locations in Cayal, Campeche, from January to December 2003 to determine the fluctuation of the adult fruit fly complex in mango and sweet orange orchards. Sixteen McPhail traps were installed at eight mango and eight sweet orange orchards. Every seven days, captures were counted. Anastrepha ludens, A. serpentina, A. obliqua and A. striata were identified. Ten-day averages of temperature, precipitation and relative humidity were calculated with data from a nearby weather station to determine its relationship with the population of the fruit fly complex. A. ludens was the species with the highest population in both crops during the fructification stage. Significant correlations were found between the population of A. ludens and precipitation in mango and sweet orange and of A. serpentina in mango.
