One of the aims of WG1 and the Task Force Ophraella is to assess the potential impact of candidate biocontrol agents of Ambrosia. We will do this by coupling demographic models of the biocontrol agents (insects) with those of the plant, developed by the Task Force Population Dynamics. Such a model would be of a high practical value to predict the interactions between both species and their spread over Europe.
To design the experiments needed to parameterise the models, several SMARTER members and modelling expert Yvonne Buckley met in March 2015 in Sheffield, UK, where they also presented the project in the symposium ‘Demography beyond the Population’, organized by the British Ecological Society (download the poster presentation here).
We specifically discussed the case of the ragweed leaf beetle Ophraella communa, and its impact on Ambrosia artemisiifolia. We designed experiments that will be carried out in Northern Italy, starting in May 2015, and agreed on a STSM of Benno Augustinus (CABI, Switzerland) to Eelke Jongejans (Nijmegen, Netherlands) in April 2015.
