Population dynamics of Lucilia eximia (Dipt., Calliphoridae)

The theoretical dynamics of experimental populations of Lucilia eximia was investigated as an attempt to understand its population biology. Specifically the population dynamics of L. eximia was analysed by means of a mathematical model that incorporates fecundity and survival as density-dependent demographic parameters in discrete time. The sensitivity of these parameters to changes in the magnitude was also investigated. The mathematical model applied to experimental populations of L. eximia predicts a theoretical one-point equilibrium for immatures. The population dynamics of L. eximia is compared to the dynamics of Chrysomya species and Cochliomyia macellaria.Univ Estadual Paulista, Inst Biociencias, Dept Parasitol, BR-18618000 São Paulo, BrazilUniv Estadual Paulista, Inst Biociencias, Dept Bioestat, BR-18618000 São Paulo, BrazilUniv Estadual Paulista, Inst Biociencias, Dept Parasitol, BR-18618000 São Paulo, BrazilUniv Estadual Paulista, Inst Biociencias, Dept Bioestat, BR-18618000 São Paulo, Brazi

Population dynamics of Chrysomya megacephala (Diptera : Calliphoridae) at different temperatures

In this study we analysed the theoretical population dynamics of C. megacephala, an exotic blowfly, kept at 25 and 30degreesC, using a density-dependent mathematical model, with parametric estimates of survival and fecundity in the laboratory. No change in terms of oscillation patterns was found for the two temperatures. The populations exhibited a two-point limit cycle, i.e. oscillations between two fixed points, at 25 and 30degreesC. However a quantitative change was observed, indicating that at 25degreesC the number of immatures in equilibrium is 1176 and at 30degreesC, 1944. The implications of this difference in terms of equilibrium for population dynamics of C. megacephala are discussed
