The invasive leafhopper Scaphoideus titanus is spreading in Europe from ca. 35 to 50°N. According to the origin area of this insect, we hypothesized that its Southern limit of distribution could partly be the consequence of the lack of cold temperatures that are essential to break egg diapause. We investigated the effects of winter incubation temperature on hatching and post hatching development. Here, we conclude that winter temperatures could be one from other key factors explaining the weak colonization of Southern vineyards in Europe by S. titanus.Read less <
