Prve najdbe štirih vrst jajčnih parazitoidov ščitastih stenic (Pentatomidae) v Sloveniji: Trissolcus scutellaris (Thomson, 1861), Trissolcus viktorovi Kozlov, 1968, Trissolcus festivae (Viktorov, 1964) in Telenomus chloropus (Thomson, 1861) (Insecta, Hymenoptera, Scelionidae) | First records of four species of egg parasitoids of stink bugs (Pentatomidae) in Slovenia: Trissolcus scutellaris (Thomson), Trissolcus viktorovi Kozlov, Trissolcus festivae (Viktorov) and Telenomus chloropus (Thomson) (Insecta, Hymenoptera, Scelionidae)

slovène. Jajčni parazitoidi so skupina naravnih sovražnikov, ki v naravi vplivajo na zmanjševanje števila škodljivih žuželk, uporabljajo pa se tudi v okoljsko sprejemljivih sistemih zatiranja škodljivcev v rastlinski pridelavi. V članku predstavljamo štiri vrste parazitoidnih os iz družine Scelionidae, in sicer vrste Trissolcus scutellaris, Trissolcus viktorovi, Trissolcus festivae in Telenomus chloropus, ki spadajo med jajčne parazitoide ščitastih stenic (Pentatomidae). Prve tri vrste smo v Sloveniji potrdili kot naravne sovražnike pisane stenice (Eurydema ventralis Kolenati, 1846 ), zadnjo vrsto pa kot jajčnega parazitoida marmorirane smrdljivke (Halyomorpha halys Stål, 1855). Nobena od navedenih vrst naravnih sovražnikov še ni navedena v Pozitivnem seznamu Evropske in sredozemske organizacije za varstvo rastlin (EPPO), zato jih ne moremo uvrstiti na Seznam domorodnih vrst organizmov za biotično varstvo rastlin, s čimer bi bila v Sloveniji dovoljena njihova uporaba v inokulativnem biotičnem zatiranju škodljivcev v kmetijski pridelavi na prostem. Na večji pomen navedenih jajčnih parazitoidov pri zatiranju gospodarsko škodljivih stenic v okviru varovalnega biotičnega varstva pa lahko vplivamo z uporabo drugih okoljsko sprejemljivih načinov zatiranja škodljivih organizmov.

anglais. Egg parasitoids are a group of natural enemies that reduce the number of harmful insects in nature, and are also used in environmentally acceptable pest control systems in crop production. In the article, we present four species of parasitoid wasps from the family Scelionidae, namely the species Trissolcus scutellaris, Trissolcus viktorovi, Trissolcus festivae and Telenomus chloropus, which belong to egg parasitoids of stink bugs (Pentatomidae). In Slovenia, we confirmed the first three species as natural enemies of the cabbage bug (Eurydema ventralis Kolenati, 1846), and the last species as an egg parasitoid of the brown marmorated stink bug (Halyomorpha halys Stål, 1855). None of the mentioned species of natural enemies is yet listed in the Positive List of the European and Mediterranean Plant Protection Organization (EPPO), so in Slovenia we cannot include them in the List of native species of organisms for biological control, which would allow their use in inoculative biological control in outdoor agricultural production. The greater importance of the mentioned egg parasitoids in the suppression of economically harmful stink bugs in the context of conservation biological control can be influenced by using other environmentally acceptable methods of controlling harmful organisms.
