P. Leisnham ; I. Jamieson | 20021. Despite widespread acceptance of metapopulation theory, the effects that inter-patch dispersal and variability in patch size have on metapopulation dynamics in insects are two issues that require further study. In addition, previous studies o[...]article/chapitre/communication
1. Here we describe a new model for the biological control of the pest weevil Sitona discoideus by the parasitoid Microctonus aethiopoides. Based on an earlier empirical model, the new model was expanded to include explicit dispersal in a couple[...]article/chapitre/communication
The interplay of dispersal, disturbance, and local dynamics in spatial mosaics has profound effects on the stability and viability of populations. There are two main reasons to consider spatial models in population dynamics: (1) improved estimat[...]ouvrage

J. Losey ; M. Eubanks | 2000The pea aphid, Acyrthosiphon pisum (Harris), attacks a wide range of legumes including many important forage and vegetable crops. Although economic injury levels for pea aphids are seldom exceeded in forage crops, aphid densities can reach extre[...]article/chapitre/communication

1. Studies of the spatio-temporal dynamics and structure of populations have identified many categories of population type. However, recognized categories intergrade, making it difficult to assign empirical population systems to single categorie[...]
