Establishment and optimisation of a monitoring network for emerging pest insects under climatic warming.
Under the current climate scenarios for Switzerland, the climate continue to warmover the coming decades. This will probably modify the complex of pest species found in crops as well as their phenology. A network of plots was set up in the Geneva Canton between 2014 and 2016 in order to monitor nine emerging pest insects: Halyomorpha halys, Nezara viridula, Zeuzera pyrina, Tuta absoluta, Diabrotica virgifera, Ostrinia nubilalis, Lobesia botrana, Eupoecilia ambiguella, Scaphoideus titanus. The network allowed to determine the presence and the abundance of these species and to develop methods for their early detection. The observations of this project permitted especially to proof the presence of H. halys in urban area, to quantify the establishment and associated damages of N. viridula in protected crops or even to demonstrate the expansion of the distribution of S. titanus in the vineyard of Geneva.
