Bois noir ( BN ) is an economically important grapevine yellows disease induced by the stolbur phytoplasma and principally vectored cixiid H yalesthes obsoletus . This study addresses involvement of other planthoppers and/or leafhoppers in epidemics S outh B anat district northeastern erbia, performing transmission experiments multilocus typing isolates to determine vector‐related characteristics disease. Transmission trials were conducted with adults two congeners, R eptalus panzeri...
Flavescence dorée (FD) is a European quarantine grapevine disease transmitted by the Deltocephalinae leafhopper Scaphoideus titanus. Whereas this vector had been introduced from North America, possible origin of FD phytoplasma needed to be challenged and correlated with ecological genetic drivers emergence. For that purpose, survey diversity these phytoplasmas in grapevines, S. titanus, black alders, alder leafhoppers clematis were conducted five countries. Out 132 map genotypes, only 11...
Epidemiological aspects and transmission routes of bois noir ( BN ), a grapevine yellows disease induced by ‘ Candidatus Phytoplasma solani’, have been exhaustively studied in the affected vineyards continental Europe but not Mediterranean coastal zone. Because Ca . solani’ its principal vector Hyalesthes obsoletus presumably originate from Mediterranean, gaining knowledge epidemiological peculiarities this area is essential for understanding global spread diversification, as well designing...
Abstract The European lantern fly, Dictyophara europaea , is an alternative vector of the Flavescence dorée phytoplasma (FDp) disease grapevine in vineyards, enabling infection initiation from wild reservoir compartment ( Clematis vitalba ). Heretofore recorded rate D. FDp‐infection has been very low (3%), making it less epidemiologically significant than would be expected based on plant (30%). In this study we present findings a heavily FDp‐infected population (>60%), natural Wolbachia...
The stolbur phytoplasma vector Hyalesthes obsoletus is generally considered as a polyphagous species associated with numerous wild and cultivated plants. However, recent research in southeastern Europe, the distribution centre of H. area most stolbur-inflicted crop diseases, points toward specific host-plant associations vector, indicating vector-based transmission routes. Here, we study specificity populations four host-plants using mitochondrial nuclear genetic markers, evaluate evolution...
Elm yellows phytoplasmas (EY) belonging to the 16SrV‐A subgroup were recently proposed as a new candidate species ‘ Candidatus Phytoplasma ulmi’. These pathogens infect elm trees, causing leaf yellowing and premature drying. In this study, 25 isolates originating from localities in northeast, east southwest Serbia characterized by means of RFLP analysis DNA sequencing four genomic loci: 16S rRNA, ribosomal protein rpl22 ‐ rps3 , secY map . total, five different genotypes identified based on...
Abstract In August 2008, grapevine yellows (GY)‐like symptoms were observed in vineyards near Podgorica, Montenegro. A survey of the grape growing area Montenegro was conducted to identify and determine distribution phytoplasmas associated with grapevine. Phytoplasmas detected symptomatic vine plants using PCR universal primers for amplification phytoplasma 16S rRNA gene. From 42 sampled, 36 positive presence phytoplasmas. RFLP profiles rDNA all isolates tested indicated that they belong...
During October and November 2014, a survey was conducted in order to establish the presence of invasive pest Drosophila suzukii (Matsumura, 1931) on territory Serbia. Survey revealed this fly four districts (Rasinski, Mačvanski, Raški Pčinjski), sampled raspberry blackberry ripe fruits, as well common fig grape. Collected fruits were used for rearing Drosophilid larvae adults, which subsequently subjected morphological molecular characterization. The D. confirmed all surveyed districts,...
Abstract The European lantern fly Dictyophara europaea (Linnaeus, 1767), is a polyphagous dictyopharid planthopper of Auchenorrhyncha commonly found throughout the Palaearctic. Despite abundant data on its distribution range and reports role in epidemiology plant-pathogenic phytoplasmas ( Flavescence dorée , FD-C), literature regarding biology host plants this species scarce. Therefore, aims our study were to investigate seasonal occurrence, plant associations, oviposition behaviour immature...
Flavescence dorée (FD) is a European quarantine disease of grapevine caused by FD phytoplasma (FDp) transmitted the leafhopper North American origin Scaphoideus titanus. The affects most important viticultural regions Europe and all wine-growing Serbia. Unlike insect vector, pathogen native to associated with several wild host plants among which alder trees as main source two out three map genetic clusters variants (Map-FD1 FD2). Heretofore, FDp epidemic in Serbian vineyards was thought be...
Bois noir, an economically important disease of grapevine yellows that causes significant economic losses in wine production, is associated with ‘Candidatus Phytoplasma solani’ and transmitted to grapevines by cixiids Hyalesthes obsoletus Reptalus panzeri. Polyphagous planthopper Dictyophara europaea, commonly found natural habitats, harbors phytoplasmas from distinct groups alternative vector the open epidemiological cycles Flavescence dorée phytoplasma European vineyards. This study...
Tomato leaf miner Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae), a devastating pest of tomato originating from South America has been recorded in Serbia on three localities: main greenhouse and open field production area located the vicinity town Leskovac (South Serbia), surroundings village Donji Vrtogos (near Vranje, Serbia) greenhouses complex Kraljevci (60 km west Belgrade). The presence T. was confirmed by morphological molecular study collected specimens.
Alder yellows phytoplasma (AldYp) is classified as a member of the 16SrV-group phytoplasmas and closely related to Flavescence dorée (FD), quarantined pathogen economic importance affecting vineyards across Europe. AldYp associated with common (Alnus glutinosa) grey alder (A. incana), has been reported in France, Italy, Germany, Austria, Switzerland, Baltic region, Serbia, Montenegro (1,2,4). For Macedonian vineyards, so far, neither infection grapevine nor presence main FD vector,...
Genotyping of 2 well-known weevil species from the genus Ceutorhynchus (Coleoptera: Curculionidae) distributed in west Palearctic, C. erysimi and contractus, revealed phenotype versus genotype inconsistencies a set 56 specimens (25 31 contractus) collected 25 locations Serbia Montenegro. An analysis mitochondrial cytochrome oxidase subunit I gene (COI), widely used as barcoding region, nuclear gene, elongation factor-1α (EF-1α), stable genetic divergence among these species. The average...
Alder yellows phytoplasmas (AldYp) of the 16SrV-group associated with common alder (Alnus glutinosa) and grey (A. incana) are closely related to grapevine (GY)-associated quarantine phytoplasma Flavescence dorée (FDp). AldYp have been reported in several countries where epidemic appearance FDp has confirmed (France, Italy, Serbia) (1,2). To date, presence not Montenegro; however, main vector FD phytoplasma, Scaphoideus titanus, identified Montenegrin vineyards since 2008. During a survey...
Trehalose and its precursor, trehalose 6-phosphate (T6P), are essential regulators of plant response to abiotic biotic stress. Here we used the specific host-insect interaction between Linaria vulgaris (Plantaginaceae) stem-galling weevil, Rhinusa pilosa (Mecinini, Curculionidae) with aim distinguish carbohydrate allocation patterns in herbivory, gall formation (G1, 24 h after oviposition), development (G2, 7 days oviposition) under controlled conditions. The hypothesis is that herbivory...
