Reported for the first time in Europe in 2002 in Italy (Brussino et al., 2002), this pest was detected in France in 2007 and...

Background: Resistant cultivars are key elements for pathogen control and pesticide reduction, but their repeated use may lead to the emergence of virulent pathogen populations, able to overcome the resistance. Increased research efforts, mainly based on theoretical studies, explore spatio-temporal deployment strategies of resistance genes in...

Les caractéristiques de Drosophila suzukii (fécondité, plantes-hôtes, nombre de générations…) en font un ravageur difficile à maîtriser en cultures fruitières, en particulier en verger de cerisier et en cultures de fruits rouges (fraise, framboise). Les solutions actuelles ne donnent pas entièrement satisfaction, du fait de contraintes...

The current restrictions on the use of chemical nematicides have contributed to increased root-knot nematodes (Meloidogyne spp.) problems in horticultural crops. In this context, plant resistance (R) appears as the most effective method of control, but the restricted number of cultivated vegetable species with root-knot nematode R-genes...
