Abstract

CARVALHO, Marcelo Henrique de  and  VON ZUBEN, Claudio José. Demographic aspects of Chrysomya megacephala (Diptera, Calliphoridae) adults maintained under experimental conditions: reproductive rate estimates. Braz. arch. biol. technol. [online]. 2006, vol.49, n.3, pp. 457-461. ISSN 1516-8913.  http://dx.doi.org/10.1590/S1516-89132006000400014.

The objective of this work was to evaluate some aspects of the populational ecology of Chrysomya megacephala, analyzing demographic aspects of adults kept under experimental conditions. Cages of C. megacephala adults were prepared with four different larval densities (100, 200, 400 and 800). For each cage, two tables were made: one with demographic parameters for the life expectancy estimate at the initial age (e0), and another with the reproductive rate and average reproduction age estimates. Populational parameters such as the intrinsic growth rate (r) and the finite growth rate (l) were calculated as well.

Keywords : Chrysomya megacephala; Calliphoridae; demographic aspects; reproductive parameters; cohort's mean reproductive age.
