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...
This study investigates specimens of the Asian yellow-legged hornet (Vespa velutina nigrithorax du Buysson, 1905) originating from first colony detected in Hungary. Phylogenetic analysis based on mitochondrial cytochrome oxidase c subunit 1 gene confirms their European origin and definitely identifies them as V. velutina. The detection Hungary represented species' farthest documented occurrence its established distribution at that time, highlighting significant dispersal potential. Given...
Abstract Oak gallwasps (Hymenoptera, Cynipidae, Cynipini) are one of seven major animal taxa that commonly reproduce by cyclical parthenogenesis (CP). A question in research on CP is the frequency with which lineages lose their sexual generations, and diversify as purely asexual radiations. Most oak gallwasp species only known from an generation, secondary loss sex has been conclusively demonstrated several species, particularly members holarctic genus Andricus. This raises possibility...
Abstract Oak gallwasps (Hymenoptera; Cynipidae, tribe Cynipini) are cyclically parthenogenetic insects that induce galls on specific plant hosts in the family Fagaceae. Understanding processes underlying evolution of oak associations requires knowledge phylogenetic relationships among gallwasp genera. Although three major lineages have been identified, status and several species‐poor but biologically significant genera remain unresolved. Two such Chilaspis Dryocosmus , whose western...
The cixiid species Reptalus quinquecostatus, R. cuspidatus, panzeri and melanochaetus are widely distributed in Europe receiving growing attention because of their potential role as phytoplasma vectors. Identifying the is restricted to a few specialist entomologists relies on morphology male genitalia, hampering identification juveniles females. This study provides tools for discrimination by integrating morphological description, which primarily genus identification, with new molecular...
Derived members of the endoparasitic order Strepsiptera have acquired an extreme form sexual dimorphism whereby males undergo metamorphosis and exist as free-living adults while females remain larviform, reaching maturity within their hosts. Expression transcription factor, broad (br) has been shown to be required for pupal development in insects which both sexes progress through metamorphosis. A surge br expression appears last larval instar, epidermis begins development. Here we ask if is...
The insect family Cixiidae includes economically important vectors of plant pathogens. Hyalesthes obsoletus transmits the stolbur phytoplasma (16SrXII‐A genetic group) associated with a serious grapevine yellows disease known as Bois Noir (BN). Other cixiids are currently suspected to be BN vectors, and correct identification species present in vineyards is essential for epidemiological surveys. This study aims discriminate between H. , luteipes scotti by integrating their morphological...
Twelve of the 13 bushcricket species Saga genus are bisexuals and diploids, except parthenogenetic tetraploid bush cricket, pedo. Despite a continuous research effort stretching through 1900s, taxonomic relationships still disputed. In this study, our primary aim was to reveal natural European three their Asian relatives, with special attention problematic taxonomy two subspecies: S. campbelli c. gracilis. Following phylogenetic analysis eight species, comprehensive study carried out on...
Abstract Eurytoma brunniventris is a parasitic wasp with wide range of host species. We have developed primers for nine polymorphic microsatellite loci to allow examination intraspecific population subdivision associated two aspects the biology their hosts: species (oak gallwasps) and tree on which gallwasp develops (different oak species). All amplified well across individuals collected from taxa. These are potentially value in study closely related economic pests such as seed predators...
Abstract The invasive Asian hornet ( Vespa velutina nigrithorax ) continues its spread across Europe, posing a significant threat to biodiversity, viticulture, and apiculture. Species identification on the first individuals caught in Slovakia was confirmed via molecular analysis of mitochondrial cytochrome c oxidase subunit I (COI) gene. Radio telemetry employed track foraging hornets, leading discovery nest within inaccessible private property. Mastering utilizing manual tracking techniques...
