TUCUCH-CAUICH, Fulgencio Martín; CHI-QUE, Gaspar  and  ORONA-CASTRO, Fermín. Adult population dynamics of the mexican fruit fly Anastrepha sp. (Diptera: Tephritidae) at Campeche, Mexico. Agric. Téc. Méx [online]. 2008, vol.34, n.3, pp.341-347. ISSN 0568-2517.

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. The objective of this research was to determine the fluctuation of the adult fruit fly complex in mango and sweet orange orchards. The research was carried out from January to December 2003 at eight locations in Cayal, Campeche. Sixteen McPhail traps were installed, at eight mango and eight sweet orange orchards. Each seven days, captures were counted and identified of the species: Anastrepha ludens, A. serpentina, A. obliqua y A. striata. Ten-day averages of temperature, precipitation and relative humidity were calculated with data from a nearby weather station in order 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.

Keywords : A. ludens; A. serpentina; environmental factors; mango; sweet orange.
