Abstract Spodoptera frugiperda (J.E. Smith, 1797) originates from the tropical and subtropical regions of Americas has spread to Africa, Asia, Oceania and, more recently, Europe. This paper provides first official report S. in Romania. In southern part country, adults this species were caught a pheromone trap November 2023. The identification fall armyworm was carried out at morphological molecular level. Barcode sequences Romanian specimens obtained. No damage observed fields surrounding...

Abstract The European Food Safety Authority (EFSA) was mandated by the Union (EU) to perform a group pest categorization of exotic Scolytinae (Coleoptera: Curculionidae) whose establishment in EU territory would present significant risk terms plant health. This should be used reconsider listing ‘Non‐European Scolytinae’ as quarantine pests current Regulation. In first stage, EFSA short‐listed 88 species developing on broadleaf hosts and known for their mobility, having impact levels...

In 2004, Scaphoideus titanus , vector of Grapevine flavescence dorée phytoplasma, was first recorded in Austrian vineyards. The absence the phytoplasma 2004‐06 confirmed by molecular analyses grapevine and samples. To estimate risk to viticulture a Pest Risk Analysis (PRA) conducted, following EPPO decision support scheme. highest introduction arises from extensive trade rootstocks and, especially for vineyards located along traffic routes waterways, passive or active spread vector. Climate...

Viroid-like symptoms were observed in 2016 on apple fruits of the cultivar "Ilzer Rose" southern Burgenland, Austria. Preliminary molecular biological investigations indicated that caused by a new unknown viroid. Therefore, primers designed, and whole genome sequence viroid (354 nt) was determined next-generation amplicon sequencing using Illumina MiSeq® platform (San Diego, California, USA). The secondary structure has rod-like conformation contains conserved regions (the TCR, CCR upper...

Abstract The transmission of the apscaviroid tentatively named apple chlorotic fruit spot viroid (ACFSVd) was investigated using a one-step reverse-transcription (RT) droplet digital PCR assay for absolute quantification viroid, followed by relative standard curves RT-qPCR. Our results indicate that ACFSVd is effectively transmitted grafting, budding and seeds. No has yet been observed to viroid-inoculated pome species Pyrus sp. Cydonia detected in viruliferous aphids ( Myzus persicae ,...

Bactrocera dorsalis is considered among the most destructive and economically important invasive fruit flies worldwide. Native to Southeast Asia, in just a few years, it has spread almost throughout all of sub-Saharan Africa, causing loss several commercially grown crops. In Europe, frequently intercepted as larva on imported fruits during phytosanitary inspections. recent adult specimens have been caught traps Austria, Italy, France, increasing level attention this species. Rapid...

Summary Regulation of the traM gene, which encodes a factor essential for conjugation resistance plasmid R1, was studied in vivo using translational gene fusions. tram ″ lacZ fusion constructs were transferred to chromosome via recombinant phage λRZ5. The level β‐galactosidase expressed by lysogens indicates that promoters are very active. Expression diminished five‐ sixfold when single‐copy plasmids R1 or R1‐19 present trans. When carrying at higher copy numbers, expression reduced as much...

Abstract The European Union (EU) regulation for fruit flies (Diptera: Tephritidae) was modified in 2022, and the broad ‘non‐European Tephritidae’ group replaced by a list of 75 regulated taxa (66 species nine genera). National Reference Laboratories EU must now be able to identify all them, whatever development stage, order carry out official surveillance. To help laboratories, Laboratory Insects Mites developed an interactive multi‐entry online key called Q‐Tephrikey. is freely available on...

A survey concerning registration of plant protection products was carried out in 41 EPPO member countries. Twenty six countries responded and results are summarized three groups. Various models discussed which seek to adapt product dosage the crowns fruit‐tree crops. The tree row volume model (TRV) is favoured by authors since it can adequately cope with wide variability orchards encountered across Europe. It suggested that experimenters who carry field trials should measure height width...

Esca, known from Austria since it was reported by Zweigelt (1933), has increased in importance the last ten years. Investigations on the incidence of esca were therefore undertaken to assess its impact Austrian viticulture. A visual assessment 14,000 vines showed that about 1.3 percent plants exhibited external esca symptoms. This correlated with vineyard age, but not cultivar grown. The spatial dispersal of esca, investigated monitoring contaminated vineyards, seemed be random....

Summary In 2015, 119.2 t of active ingredients antibiotics were used in Austria human medicine (70.4 t; 59.1%), for food animals (48.8 40.9%) and plant production (0.002 < 0.1%). During the last five years, consumption increased by 3.8% (2011: 67.8 2015: 70.4 t). hospitals, it 17.3%, from 19.7 2011 to 23.1 2015. community, measured kg ingredient, 0.3% Consumption defined daily dose (DDD) per 100,000 inhabitants year decreased 3.6%. Our numbers community (2015: 17.0 DDD) contradict AURES...

Comparative study ofthe soil-living nematofauna associated with vine ( Vitis spp.) infested phylloxera Viteus vitifoliae Fitch) The diversity and the community structure of nematodes, correlation between occurrence nematodes infestation grapevines grape ) were studied. Grapevines ungrafted grafted to different rootstocks planted samples roots soil collected at 7 sites in Austrian growing regions Weinviertel, Neusiedlersee, Sudburgenland, Sudoststeiermark. formation nodosities on rootlets...

In April 2013, yellowing and distortion of leaves as well mosaic chlorotic ring symptoms were observed on calla lilies (Zantedeschia sp.) in nurseries Bosnia Herzegovina (Fig. 1). The virus-like present several greenhouses the vicinity Banja Luka. Disease incidence was estimated to be between 10 20% 200 plants inspected. Since ornamental plant production is great economic importance that region, symptom-bearing collected, a pooled sample frozen brought Institute for Sustainable Plant...

Several sporadic outbreaks of “flavescence doree” in the Austrian vineyards have been recorded since 2009. A long-time monitoring potential vectors and reservoir host plants phytoplasma (FD) revealed that on some sites Phlogottetix cyclops is a common insect species grapevines as well Clematis vitalba Ulmus laevis growing near vineyards. high percentage captured specimens P. harboured 16SrV-C phytoplasmas. Preliminary results showed this Asian leafhopper could aquire FD from infected C....
