4. Occurrence and distribution of root-knot nematodes Meloidogyne spp. in SerbiaJasmina Bačić, Ivana Lalićević, Saša Širca, Melita Theuerschuh, Nik Susič, Barbara Gerič Stare, 2025, izvirni znanstveni članek Povzetek: This study examines the occurrence and distribution of root-knot nematodes (RKN), Meloidogyne spp., in Serbia through an official survey conducted from 2021 to 2023. A total of 241 plant and soil samples were collected from 25 districts across two regions: Northern Serbia (Vojvodina Province) and Central Serbia. RKN infestations were detected in 23.7% of the samples. Among the 57 identified populations, 5 Meloidogyne species were recorded: M. incognita, M. hapla, M. luci, M. arenaria and M. javanica. Meloidogyne luci was reported in Serbia for the first time, marking a significant finding for nematology in the region. This study highlights the importance of implementing effective pest management strategies to mitigate the agricultural impact of RKN in Serbia.

5. Ogorčica Xiphinema index Thorne & Allen, 1950, prenašalec virusa pahljačavosti listov vinske trteJulija Polanšek, Stanislav Trdan, Saša Širca, 2024, izvirni znanstveni članek Povzetek: Virusi na rastlinah povzročajo veliko gospodarsko škodo, saj je zdravljenje okuženih trt praktično nemogoče v poznejši fazi rasti, ali pa so uveljavljeni postopki precej dolgotrajni, prav tako proti virusom trenutno ni učinkovitega pripravka ali ukrepa. Med očem skrite prenašalce virusov spadajo tudi ogorčice – majhni organizmi , ki lahko skupaj z virusi povzročajo velike izgube pridelka. Med takšne ogorčice spada tudi vrsta Xiphinema index. Je glavni prenašalec virusa pahljačavosti listov vinske trte (Grapevine fanleaf virus, GFLV). Vinska trta je glavni gostitelj te rastlinsko-parazitske ogorčice. S svojim značilnim dolgim cevastim bodalom – stiletom prodre in se prehranjuje na mladih koreninicah. Okužba vinske trte z GFLV iz rodu Nepovirus vodi v postopno izrojevanje vinske trte in pozneje v gospodarsko nekonkurenčnost vinograda. Obvladovanje okužb z GFLV v vinogradih je večinoma omejeno na obvladovanje ogorčice X. index, ki pa je izjemno težavno, predvsem zaradi njihove relativno dolge življenjske dobe in prostorske razporeditve v tleh. Kot najbolj učinkovita ukrepa sta se izkazala kolobarjenje na zemljišču, kjer se pojavlja ta ogorčica in praha, a sta ta pristopa ekonomsko neprivlačna, saj je za ta ukrep potrebno pustiti zemljišče pred ponovno zasaditvijo novega vinograda brez vinske trte za več let. V prihodnosti je potrebno pozornost posvetiti področju razvoja novih, okolju prijaznejših in učinkovitejših pristopov obvladovanja virusonosnih ogorčic X. index in nadomestiti uporabo nematocidov

7. Borova ogorčica, Bursaphelenchus xylophilus (Steiner & Buhrer, 1934) Nickle, 1970 - nova nevarnost za slovenske gozdove?Maja Jurc, Gregor Urek, Saša Širca, Vid Mikulič, Branko Glavan, 2003, pregledni znanstveni članek Povzetek: V prispevku obravnavamo borovo ogorčico (Bursaphelenchus xylophilus), ki je v Evropi (tudi v Sloveniji) uvrščena na karantensko listo A1. Vrsta je izredno napadalna, povzroča hitro propadanje iglavcev - predvsem vrst rodu Pinus, redko Picea, Abies in Larix. Prikazan je njen areal, ekološke zahteve, gostitelji, bionomija ter simptomi napada na borih. V okviru bionomije borove ogorčice so posebej predstavljeni njeni potrjeni vektorji (Insecta: Cerambycidae - rod Monochamus) in tudi njeni potencialni vektorji (Insecta: Curculionidae - rod Pissodes in Scolytidae). Podajamo razširjenost potencialnih gostiteljskih rastlin borove ogorčice pri nas, podnebne razmere ter kritične točke za vnos in širjenje škodljivca. Ocenjujemo stopnjo fitosanitarnega tveganja pojava borove ogorčice v Sloveniji.

9. Record of a new location for tropical root knot nematode Meloidogyne luci in SloveniaBarbara Gerič Stare, Polona Strajnar, Saša Širca, Nik Susič, Gregor Urek, izvirni znanstveni članek Povzetek: The plant parasitic nematode Meloidogyne ethiopica Whitehead has been reported from several European countries, including Slovenia, where it was first found in 2003. However, the description in 2014 of a new sister species, Meloidogyne luci Carneiro et al., 2014, called for the reclassification of all European and Turkish populations of M. ethiopica reported up to this date as M. luci. Both species M. ethiopica and M. luci have a very wide host range of
monocotyledons and dicotyledons. They are pests of important agricultural crops such as maize, potatoes and variety of vegetables, and represent a serious threat for agricultural production in greenhouses as well as in the open fields in many EPPO countries. This paper reports a new location of the tropical root knot nematode species M. luci found in Slovenia in 2015.

10. Discrimination between abiotic and biotic drought stress in tomatoes using hyperspectral imagingNik Susič, Uroš Žibrat, Saša Širca, Polona Strajnar, Jaka Razinger, Matej Knapič, Andrej Vončina, Gregor Urek, Barbara Gerič Stare, izvirni znanstveni članek Povzetek: Crop plants are subjected to various biotic and abiotic stresses. Both root-knot nematodes (biotic stress) and water deficiency (abiotic stress) lead to similar drought symptoms in the plant canopy. In this work, hyperspectral imaging was used for early detection of nematode infestation and water deficiency (drought) stress in tomato plants. Hyperspectral data in the range from 400 to 2500 nm of plants subjected to different watering regimes and nematode infestation levels were analysed by partial least squares – discriminant analysis (PLS-DA) and partial least squares – support vector machine (PLS-SVM) classification. PLS-SVM classification achieved up to 100% accuracy differentiating between well-watered and water-deficient plants, and between 90 and 100% when identifying nematode-infested plants. Grouping the data according to the time of imaging increased the accuracy of classification. Shortwave infrared spectral regions associated with the OH and CH stretches were most relevant for the identification of nematode infested plants and severity of infestation. This study demonstrates the capability of hyperspectral imaging to identify and discriminate between biotic and abiotic plant stresses.
