Relationship between overall search rate \(s\) and the number of parasitoids \(P\) for various combinations of the number of patches (\(N\)), number of hosts (\(H\)) and host-dependent parasitoid dispersal (\(\mu\)). The overall search rate varies with the number of parasitoids in the stochastic model, while the corresponding deterministic model predicts that it is constant. \(\alpha_{i} = 1/N\) for all i and a = 1. Values shown in the plots are averages from 10,000 simulations. Some combinations show no values because all hosts were parasitized at least in one simulation
