The influence of plant dispersion on movements of the Colorado potato beetle, Leptinotarsa decemlineata (Say) (Coleoptera: Chrysomelidae), was studied with mark-recapture techniques. Beetles released between potato monocultures, polycultures with two additional non-host plant species, and polycultures with five additional non-host species, randomly colonized the three types of plots. Releases between different arrangements of potted host and non-host plants showed (1) greater beetle colonization and greater length of time spent on potato plants growing alone than on potato plants surrounded by non-host vegetation, and (2) no effect of potato plant density on colonization or tenure time. Overall, there was a 65~ recapture rate; beetles consistently stayed on the same plants they originally colonized, often for at least five days after release.
