Abstract
A pods of indigo bush (Amorpha fruticosa L.), an invasive plant species were collected during 2017. in the area of the Pokupski basin and in Županja. In the laboratory there were observed exit holes on pods, which determined the presence of the invasive beetle species Acanthoscelides pallidipennis (Motschulsky, 1873). This species is native to the territory of North America, and its distribution is closely related to the habitats of the indigo bush. In the area of Pokupski basin within the collected samples there were found 554 infested pods, moreover in Županja there were 434 infested pods. Therefore, statistically significant difference was not found within two study sites. The results indicate that the A. pallidipennis is widespread in amorphous stands in both study sites and thus it is necessary to monitor the potential of its spreading in order to prevent infestation of other plant species, especially those from the Fabaceae family that are frequently infested.
