I did several field works in south of France to observe and collect V. velutina specimens:
2007: 45 days of V. velutina colony observations and collects of V. velutina prey pellets with Jean Haxaire (entomologist) near Agen.
2008: 2 months observations of V. velutina in cropfield to assess the potential impact of V. velutina on strawberry production by overpollination in Dordogne. (The impact was absent. This work was the result of an overstatement made by a local self-claimed expert pressing governmental institution to react.)
2008 – 09: several short trips (1 week) to collect prey pellets of V. velutina in Dordogne.
2009: 3 weeks of Vespidae collects across Thailand with Adam Cotton.
2010: 5 weeks of Vespidae collects across Java and the lesser Sunda Islands with Y. Suhardjono and O. Effendy (LIPI).
Our team at the Ranamese scientific station in Flores.
2010: 3 weeks of Vespidae collects around Zhejiang province with Pr. X. Chen and T. Jiangli (University of Zhejiang).
Our team in Zhejiang province with Tan Jiangli.
