WG1 meeting initiates coupled plant-insect population models (Sheffield, March 2015)

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.

Risks of non-target attack by Ophraella communa: poster at Neobiota 2014 conference

Ophraella_Poster_Neobiota-2014_Antalya_Toth-et-al

The Ambrosia leaf beetle (Ophraella communa LeSage, Coleoptera: Chrysomelidae) mainly feeds on ragweeds, especially Ambrosia artemisiifolia. Recently, during the summer 2014, the species was found to feed as larva and adult under field conditions on Artemisia vulgaris L., Helianthus annuus L., H. tuberosus L., Inula graveolens (L.) Desf., and Xanthium strumarium L.

O. communa is regarded as a successful biological control agent against A. artemisiifolia in China, but the picture is not straightforward. The present study suggests that additional experiments are needed to assess the impact and the risks of non-target attack by this potential biological control agent under field conditions.

Common ragweed (Ambrosia artemisiifolia L.) seeds in bird food in Luxembourg in 2007 and 2012

Ambrosia-in-bird-seed-in-Luxembourg-2012_300pxThis study looks at the presence of common ragweed seeds in bird food in Luxembourg in 2012 and compares the results with an earlier study conducted in 2007. The study has been conducted by Christian Ries, Yan Steil and Patrick Thommes at the Department of Ecology in the National Museum of Natural History in Luxembourg,

The poster was presented on March 16th 2013 at the “XXXe réunion annuelle des collaborateurs scientifiques du Musée national d’histoire naturelle Luxembourg”.
