The Task Force Ophraella met on 11 and 12 April 2015 in the area where the ragweed leaf beetle Ophraella communa has established. On a joint field trip in the Milano area, they found egg batches on seedlings of Ambrosia artemisiifolia. By sweep netting they collected female and male beetles, brought to the University of Fribourg to start a new rearing in the quarantaine facilities.
Next day, the Task Force was hosted by the Museum of Natural History in Lugano, Switzerland. Members exchanged results obtained in 2014, and the invited speaker Yuya Fukano from Tokyo University of Agriculture and Technology updated them about the status quo of the work on Ophraella communa in Japan. Several Task Force members initiated new collaborative experiments starting in 2015.
