Distribution map of the Torymus sinensis experimental releases done between 2011 and 2014 in continental France and Corsica (rescaled in box). Red circles, 1x100 females released; green circles, 2x50 females released; blue circles, 1x1 000 females released; purple circles, 2x110 females released

The objective of the project was to implement in France a classical biological program against the chestnut gall wasp, Dryocosmus kuriphilus (Dk), using releases of the exotic parasitoid Torymus sinensis. The expected outcome of this project were (i) the permanent establishment of the parasitoid and (ii) an efficient and long-term control of the pest.
