| contents | <p><span lang="EN">The economically significant Beet yellows virus (BYV) negatively affects sugar beet yields. For the past 30 years, effective control of BYV relied on neonicotinoid insecticides. However, the European Union's ban on outdoor use of these insecticides since 2018, driven by concerns over biodiversity and human health, led to widespread losses in the sugar beet industry due to virus outbreaks. The main vectors of this virus are the green peach aphid (<em>Myzus persicae</em>) and the black bean aphid (<em>Aphis fabae</em>). Understanding the virus-vector relationship is crucial for developing new control methods. To address this, our study investigates viral transmission efficiency in sugar beet plants depending on aphid density, species, and morphs (winged/apterous) in laboratory and greenhouse conditions. Laboratory experiments assessed virus transmission from an infected plant to a vector and from a vector to a healthy plant, while greenhouse experiments observed viral transmission changes when both vector species coexisted on the same infected plants simultaneously (i.e. by analogy to the fields). In the laboratory experiment, the best vector of BYV at low density was the winged morphs of <em>M. persicae</em> with a 25% transmission probability after three weeks with only three viruliferous aphids present. In the greenhouse experiment, a significantly higher transmission probability was observed at early infestation stage when both vector species were present at the same time on the same patch. This study provides valuable insights into how aphid species, density, and morphs may together affect the transmission of the virus, setting foundation for future studies on virus control.</span></p> |
