ABSTRACT
In Mexico, mango is seriously affected by the mombin fly, Anastrepha obliqua, which is present in orchards from March to August. Flies were obtained in the field through intensive collection of mango and mombin in the Soconusco region, Chiapas, Mexico. This chapter aims to investigate differences in all biological measures between populations of A. obliqua obtained from naturally infested mango and mombin. The average pupal weight obtained from mango was significantly greater than that from mombin. The reproduction rate (Ro), intrinsic increasing ability, and the generation time were greater in populations from mombin. The difference in Ro was due to greater egg fertility in A. obliqua reared in mombin. Larvae obtained from mombin showed a greater age standardization, which results in more uniform pupation. Several biological and demographic aspects of A. obliqua that had fed in mango and mombin during their larval stage under field conditions were compared.
