Popis: The wheat dwarf disease is among the most damaging diseases in cereals. Its aetiological agent is theWheat dwarf virus(WDV), which is exclusively transmitted from plant to plant by leafhoppers from the genusPsammotettix(Hemiptera, Cicadellidae). The parameters linked to the WDV/Psammotettixpathosystem are still poorly understood. We studiedPsammotettixindividuals collected in wheat and barley fields in France and, as a comparison, from grassland at agroecological interface in West Slovenia. Species identity of males and females has been determined using multiple criteria. In the first step, the characterization of the collected individuals included recordings of vibrational signals used in mating behaviour and morphometric analyses. In addition, a 442 nt sequence of the mitochondrial cytochrome oxydase I (COI) gene was obtained for some individuals and compared to COI sequences of thePsammotettixleafhoppers available in public databases. In the cereal fields in France,Psammotettix alienuswas the most numerous species; however, it sometimes occurred together withPsammotettix confinis, while in the grasslands in Slovenia, the third syntopic species inPsammotettixcommunity wasPsammotettix helvolus. The temporal parameters of theP. alienusmale calling song that were measured in this study were very similar to those measured in a previous study. The local biotic and/or abiotic parameters most likely influence the life history ofPsammotettixleafhoppers, and the proportion of viruliferous individuals collected in cereal fields was 14.9%, while leafhoppers collected in Slovenia were virus-free. Taken together, results show that more detailed information on population structure ofPsammotettixleafhoppers is crucial for providing an insight into the epidemiology of wheat dwarf disease.
