Marrying research and management activities: adaptive management of Grape leafhopper Scaphoideus titanus / M. Jermini, V. Trivellone, C. Cara, I.E. Rigamonti, J. Baumgärtner. - In: IOBC/WPRS BULLETIN. - ISSN 1027-3115. - 85:(2013), pp. 49-56.
Abstract:
This paper deals with the study and management of the Grape leafhopper Scaphoideus
titanus Ball, vector of the Candidatus Phytoplasma vitis pathogen, in vineyards located in Southern
Switzerland. S. titanus is an invasive species of North American origin that became a component of a
complex population system and an object of a complex population management set-up. Uncertainities
have been recorded in three areas: uncertainty about the observations and measurements, uncertainty
about the underlying behavior of the system and uncertainty about the environment. For dealing with
complex problems high in uncertainty, an adaptive management (AM) strategy is developed and
implemented. Progress is reported in the area of technology selection for measuring infestation levels
and temperature profiles (i), the quantitative analytical tools have been advanced as to obtain a better
insight into the dynamics of the population system (ii) and the timing of insecticide applications and
monitoring operations (iii), the ground has been solidified for the design and implementation of an
integrated population and disease transmission system (iv). The detailed presentation of the
methodologies and the results of different component studies by Rigamonti et al. (2011a; 2011b;
2013), Prevostini et al. (2013) and Trivellone et al. (2011) allows focusing on AM design,
implementation and preliminary achievements. The AM framework was concluded to be adequate for
dealing with high uncertainties associated with the complexities of the S. titanus population system
and the design and implementation of an IPM program
