After comparing the persistence of four marking techniques, a mark?release?resight study was performed to characterize mid-season movement of the Colorado potato beetle [Leptinotarsa decemlineata (Say); Col., Chrysomelidae] simultaneously in a fallow and in a wheat field. Isolated patches of potatoes were installed in a random spatial arrangement on both fields similarly. Overwintered beetles were individually marked and released. Beetles showed limited inter-patch movement activity (15.9% of recovery events) with an overall mean daily dispersal of 0.309 m (0.0?7 m). There was a significant difference in the insects? movement distance between the fallow and wheat field but there was no difference between the movement distances of males and females. The distance between the patches varied between 1 and 7.81 m, and inter-patch movement was infrequent (15.9%). Results suggest that surrounding fields by wheat rather than fallow grounds should be studied as a possible strategy to reduce the movement of overwintered beetles between potato fields.
