In study, the dispersal of Colorado potato beetles (Leptinotarsa decemlineata) (Say) (Coleoptera: Chrysomelidae) in the province of Afyonkarahisar has been investigated. The aim of this study is that, it is one of the most important pests of potatoes which are grown in Turkey. Because of this, certain districts in Afyonkarahisar -the central district, Sandikli, Suhut, Dinar, Emirdag, Cobanlar - were visited four times, and the potato beetles were collected from the fields. Additionally, two potato fields (Erkmen and Sihlar neighborhoods), which have 4 kilometers distance between, in the district of Bolvadin were settled as the sampling area so as to determine the population change of potato beetles in Afyonkarahisar. Every week, potato beetles (eggs, larvae, pupa) were collected from these fields and recorded. In the central district of Afyonkarahisar, less potato beetles were detected in the potato fields where chemicals were intensively used. Egg numbers of the fields in Erkmen and Sihlar neighborhoods were 1165 and 556, respectively. Fluctiations of potato beetles for both fields were drawn.
