Última Larval predation on different instars in blowfly populations BABT Faria,Lucas Del Bianco; Godoy,Wesley Augusto Conde; Reis,Sérgio Furtado dos. During its larval stage, Chrysomya albiceps (Diptera: Calliphoridae) is a facultative predator on other blowflies. In this study, we evaluated the predation by third instar larvae of C. albiceps on first, second and third instar larvae of Chrysomya megacephala and Cochliomyia macellaria in no-choice experiments in order to compare the vulnerability of larval instars to predation. With first and second instar prey the highest predation rate by C. albiceps was on C. megacephala. For third instar prey, the highest predation rate was on C. macellaria. With second instar prey, there was complete predation on C. megacephala within 90 min, whereas in C. macellaria only 55% of the larvae were eaten by 90 min. For third instar prey most predation on C. macellaria... Tipo: Info:eu-repo/semantics/article Palavras-chave: Chrysomya albiceps; Blowflies; Larval predation; Optimal foraging.

Mol. Biol. Duarte,Luiza Carla; Von Zuben,Fernando José; Reis,Sérgio Furtado dos. The effect of an increase in quantitative continuous characters resulting from indeterminate growth upon the analysis of population differentiation was investigated using, as an example, a set of continuous characters measured as distance variables in 10 populations of a rodent species. The data before and after correction for allometric size effects using orthogonal projections were analyzed with a parametric bootstrap resampling procedure applied to canonical variate analysis. The variance component of the distance measures attributable to indeterminate growth within the populations was found to be substantial, although the ordination of the populations was not affected, as evidenced by the relative and absolute positions of the centroids. The covariance... Tipo: Info:eu-repo/semantics/article Ano: 1998 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1415-47571998000400013 Registros recuperados: 2 Primeira ... 1 ...
