L’antagoniste du cynips du châtaignier est en Suisse!
Torymus sinensis, le parasitoïde exotique lâché en Italie pour lutter contre le cynips du châtaignier a été détecté pour la première fois en Suisse, au Tessin. L’insecte est arrivé naturellement malgré les précautions environnementales prises par la Suisse. Un article paru dans La Regione Ticino mardi 10 septembre 2013, PDF

“Cinipide, la lotta biologica funziona” by Luca Berti, in La Regione Ticino
Torymus sinensis, a chinese hymenopteran parasitoid is considered as the only antagonist of the chestnut gall wasp Dryocosmus kuriphilus. After the invasion of the gall wasp in Ticino’s chestnut forests, cantonal authorities sought an homologation of T. sinensis by the Federal Office for the Environment. A very good paper by Luca Berti (published the 4th…

Torymus sinensis: a viable management option for the biological control of Dryocosmus kuriphilus in Europe?
The chestnut gall wasp Dryocosmus kuriphilus is a global pest of chestnut (Castanea spp). Established as a pest in the mid-twentieth century in Japan, Korea and North America, this species was first reported in Europe in 2002. Following the successful release of a biological control agent Torymus sinensis in Japan, this parasitoid species has been…
Detecting arthropod intraguild predation in the field
The process of biological control carries a distinct risk that an alien biological control agent (BCA) will become established as an invasive alien species with an associated threat to the local ecosystem biodiversity. It is imperative that a wide-ranging environmental risk assessment (ERA) is performed before the release of any BCA. This should include considering…
