Abstract

Demographic parameters for Anastrepha ludens (Loew), A. obliqua (Macquart), and A. serpentina (Wiedeman). reared on two artificial diets and several natural hosts are reported. These include preadult survival and development rates, adult survival and fecundity and population parameters such as the intrinsic rate of increase, mean generation time and stable age distribution. All three species displayed similar life history patterns. Egg development required approximately three days, larval development 8-13 days, and pupation 13-17 days. The number of eggs per female (gross fecundity rate) ranged from 84 to 102. A. serpentina, compared with the other two species, displayed much higher survival in the first two weeks of adult life. This led to a higher net reproductive rate despite a lower gross fecundity relative to the other two species. The three species described here have different demographic characteristics compared to those of the ecologically similar tephritids Ceratitis capitata and Dacus spp.
