The leafhopper Scaphoideus titanus is the harmful vector of the phytoplasma causing the Flavescence dorée, one of the current major threats in European viticulture. The ecology of this insect is however poorly known even if better understanding of this species’ life history traits and behavior will improve our ability to foresee the epidemiology of the disease. We investigated the aggregative behavior of the larvae. We conclude from different experiments that larval aggregation occurs at the plant scale, but we could not clarify the factors cueing such an aggregation. Also aggregative oviposition patterns may occur and reinforce such aggregation under young leaves. These aggregation patterns should be studied in more details in order to gain knowledge in the epidemiology of Flavescence dorée and eventually to develop control strategies based on inter-individual epideictic regulation.Read less <
