1. Scaphoideus titanus forecasting and management : quo vadis?Elena Gonella, Giovanni Benelli, Nathalie Arricau-Bouvery, Domenico Bosco, Meta Virant-Doberlet, 2024, review article Abstract: Scaphoideus titanus Ball (Hemiptera: Cicadellidae) is a major pest for European viticulture due to its high efficiency in the transmission of one of the most destructive pathogens for grapevine, namely flavescence dorée phytoplasmas. Although it plays a major role in spreading this disease, S. titanus is part of a complex epidemiological cycle involving several alternative vectors with variable relevance for phytoplasma spread. Here we provide an updated review on S. titanus monitoring and modelling, as well as the available tools for management of this pest and for limiting phytoplasma transmission and, thus, also spread. Insecticide-based control is examined; additional emphasis is placed on innovative and low-impact control approaches, such as vibrational mating disruption, biocontrol, and methods to reduce vector competence. We also discuss the main emerging challenges to the implementation of effective and sustainable control programs against S. titanus.

2. Scaphoideus titanus up-to-the-minute : biology, ecology, and role as a vectorElena Gonella, Giovanni Benelli, Nathalie Arricau-Bouvery, Domenico Bosco, Meta Virant-Doberlet, 2024, review article Abstract: Native to the Nearctic region, Scaphoideus titanus Ball (Hemiptera: Cicadellidae) has become a major threat for grapevine production after being unintentionally introduced into Europe, where it became the main vector of flavescence dorée phytoplasma, being mainly associated with the genus Vitis. Scaphoideus titanus is a highly efficient vector of the most important phytoplasma affecting grapevine. For this reason, compulsory insecticide treatments have been introduced against this pest in many European countries. Moreover, the continuous expansion of its geographical distribution makes this leafhopper a serious threat for several non-European Countries. In this article, we review the current knowledge about its taxonomy, morphology, biology, ecology, and its role as a vector. Finally, we point out the main challenges for research aimed at reducing S. titanus and flavescence dorée expansion across Europe and avoiding spread of the disease outside the Old World.

4. A study of important entomofauna in oak forests of SloveniaMiroslav Harapinov, Maja Jurc, 2000, original scientific article Abstract: Insects in 9 research areas in pedunculate oak and sessile oak forests in Slovenia have been studied. We identified 35 insect species as well as two genera from 13 families. The defoliation of oak leaves in studied forests was between 10 and 90 %. More than 80 % of the defoliation was caused by mottled umber and winter moth (Erannis defoliaria Cl., Operophthera brumata L.). Leaf-roll moths are an important group of pests of oak leaves and acorns. The most numerous is the green leaf-roll moth, Tortrix viridana L., followed by Archips crataegana Hb., Laspeyresia splendana Hb. and Laspeyresia amplana Hb. The ratio of appearance of oak sawflies (Apethymus abdominalis Lep. and Apethymus braccatus Gmel.) was 9 : 1. During the past 10 years, oak miner (Tischeria complanella Hb.) has attacked young oak trees heavily. Acorn destroyers (Balaninus glandium Mrsh. and Balaninus nucum L.) were important acorn pests. During the gradation of defoliators in the Prekmurje region of Slovenia there was an increased population density of their predators, such asground beetles and burying beetles (Calosoma sycophanta L., Calosoma inquisitor L., Carabus spp., Xylodrepa quadripunctata L. We can confirm that the health of oak forests in Slovenia is better than in Croatia and southeastern Europe.

5. Additions and omissions to the list of hoverfly fauna (Diptera: Syrphidae) of SloveniaMaarten De Groot, Roman Luštrik, Tim Faasen, Dare Fekonja, 2010, original scientific article Abstract: The changes in the checklist of hoverflies of Slovenia are presented. Fifteen species are recorded as new for the fauna of Slovenia: Brachyopa panzeri, Brachypalpus laphriformis, Callicera aenea, Chamaesyrphus scaevoides, Chalcosyrphus valgus, Melangyna lasiophthalma, Meligramma guttata, Merodon aberrans, Parhelophilus frutetorum, Orthonevra intermedia, Platycheirus occultus, Rhingia borealis, Spazigaster ambulans, Sphaerophoria chongjini and Sphaerophoria fatarum. From the species complex of Merodon aeneus, both M. aeneus species A/B and M. aeneus C were recorded. One species, Xylota caeruliventris, was omitted from the checklist because of misidentification. Information on habitat characteristics, range and conservation status is givenfor every new species.
