Abstract

GODOY, Wesley Augusto Conde; VON ZUBEN, Fernando José; VON ZUBEN, Cláudio José  and  REIS, Sérgio Furtado dos. Spatio-temporal dynamics and transition from asymptotic equilibrium to bounded oscillations in Chrysomya albiceps (Diptera, Calliphoridae). Mem. Inst. Oswaldo Cruz [online]. 2001, vol.96, n.5, pp.627-634. ISSN 1678-8060.  https://doi.org/10.1590/S0074-02762001000500006.

The sensitivity of parameters that govern the stability of population size in Chrysomya albiceps and describe its spatial dynamics was evaluated in this study. The dynamics was modeled using a density-dependent model of population growth. Our simulations show that variation in fecundity and mainly in survival has marked effect on the dynamics and indicates the possibility of transitions from one-point equilibrium to bounded oscillations. C. albiceps exhibits a two-point limit cycle, but the introduction of diffusive dispersal induces an evident qualitative shift from two-point limit cycle to a one fixed-point dynamics. Population dynamics of C. albiceps is here compared to dynamics of Cochliomyia macellaria, C. megacephala and C. putoria.

Keywords : spatial dynamics; sensitivity analysis; Chrysomya albiceps.
