Combining different forms of parasitoid aggregation: effects on stability and patterns of parasitism



Combining different forms of parasitoid aggregation: effects on stability and patterns of parasitism



Oikos, 562: 233-239



Two models are presented which blend different forms of parasitoid search behaviour: aggregation independent of host density, and in response to host density. In the first model (model A), parasitoid and host densities on a patch are assumed to be positively correlated, while in the second model (model B), the parasitoids have a linear regression on host density, with an associated error term. In model A, the dynamics were least stable when host and parasitoid were perfectly correlated.
