In this this study, the invasion of potato beetles (Leptinotarsa decemlineata) (Coeoptera: Chrysomelidae) in the province of Tokat, including their natural enemies and population change has been investigated. For this purpose, certain districts in Tokat, the central district, Yeşilyurt, Zile, Artova, Niksar, Başçiftlik, Erbaa, were visited and the potato beetles were collected and recorded from the prespecified potato and eggplant fields. In addition to the soil samples, the other insects except the potato beetles, collected with 100 times sweeping by butterfly net. Besides, two potato fields in Hasanşeyh Town in the district of Reşadiye were settled as the sampling area so as to determine the population change of potato beetles in Tokat. Every week, potato beetles (eggs, larvae, pupa) were collected from these fields and recorded. In addition, the other organisms in the potato field were collected using the butterfly net. As applied in the other fields, 1 kg of soil was collected from both fields to detect the existence of entomopathogenic fungus. In Zile, as a result of the studies carried out in the prespecified districts, no potato beetles were detected in the potato fields. In the research carried out on the 6th of July in 2013, in Başçiftlik, 1263 potato beetle eggs were encountered. With the sampling studies applied in the district of Niksar, 580 larvae were found
