In Slovenia, Mediterranean fruit species thrive in Primorska due to the effects of the sea. The most common of these are the olive, the persimmon and the fig. The cultivation of these species is hampered by their pests, which can spread excessively and cause damage under favourable climatic conditions. The most common pests are the olive fly, the olive moth and the olive scale. The olive fruit fly causes damage in the larval stage by boring tunnels into the fruit. The olive fruit moth causes damage in all generations, but most in the carpophagous generation by feeding on the stones in the fruit. The olive scale insect causes damage by sucking and secreting honeydew. An important pest of persimmon is the Mediterranean fruit fly, which causes damage by feeding during the larval stage. The most important pests of figs are the black fig fly and the fig scale. The larvae of the black fig fly cause damage by feeding in the fruit. The fig scale causes damage by sucking on leaves, twigs and fruit and by secreting honeydew. When overbreeding has a negative impact on crop yields, populations must be reduced. Protection is carried out with various baits and registered pesticides, which are gradually being withdrawn from the market due to their negative impact on the environment
