Abstract
Studying effects of host plant patch size on insect populations and applying the results to pest management require efficient experimental design. Ability to detect patch size effects in experiments depends on differences in population levels among different-sized patches and the variability of those population levels. This paper combines statistical analysis of variance components with a model simulating how insect populations respond to patch size, in order to analyze alternative designs. By using this method, host plant patch size, number of replicates, and number of subsamples can be chosen for efficient experiments within limits of space, labor, and experimental material. The method is illustrated with data from field experiments on Pieris rapae (L.) in collard patches.
