Native natural enemies of greenhouse pests in Slovenia

Abstract: In Slovenia, in agricultural practice, only natural enemies from the List of native
biological control agents (List) can be used to control plant pests. This list, which currently
includes 38 species of predators, parasitoids and entomopathogenic nematodes, is an integral
part of the Regulations on biological control (Official Gazette of the Republic of Slovenia, no.
45/06), and it can only includes native beneficial organisms, which are also an integral part of the EPPO positive list. Since 2006, we have systematically studied the occurrence of native
natural enemies in Slovenia, with the aim of enriching the List. This paper lists 31 species of
beneficial organisms from the List that can be used in Slovenia for controlling greenhouse pests, and 12 species of natural enemies recorded in Slovenian greenhouses that cannot yet be used against the plant pests due to the requirements of the Regulations on biological control.
