| Survival of pest in micro-plot trials (container studies) or field plot trials was monitored after exposure to commercially used EPN strains. Experimental plots were artificially infested with pest larvae that naturally burrowed into the soil for diapause. Either larval mortality or adult emergence, was assessed to estimate the control effect of the EPN treatment. Here we present preliminary results from three ongoing projects. |

| Semi-field and field experiments were carried out to evaluate the biological control potential of entomopathogenic nematodes (EPNs) against grubs in hazelnut, chestnut and cherry orchards. Mortality of hazelnut weevils in interred containers treated with 2.2x106 infective juveniles (IJ) m-2 of Heterorhabditis bacteriophora was 75.4%. H. indica caused 65.2% and S. feltiae 43.3% pest mortality, but numbers were not significantly different from the untreated control (33.4%). Mortality of the chestnut weevil was slightly increased in S. carpocapsae (2x106 IJ m-2) treated containers (44.6%) compared to untreated control containers (39.2%), but differences were either not significant. Soil applications against the European cherry fruit fly did not lead to any... |

| La flavescence dorée de la vigne et la lutte obligatoire contre son vecteur Scaphoideus titanus posent d’importants problèmes dans les vignobles conduits en culture biologique. Afin de développer une stratégie de lutte basée sur des insecticides compatibles avec la viticulture biologique, des essais en plein champ ont été conduits au Tessin en 2006-2007. Le Parexan N (pyréthrine + huile de sésame) s’est avéré le seul produit biologique efficace à plus de 90% contre les formes immatures de S. titanus, par contre il n’a eu aucun effet contre les adultes. L’application répétée de Parexan N s’est montrée toxique pour les typhlodromes de l’espèce Amblyseius andersoni. Malgré cette toxicité, la seule stratégie de lutte efficace et recommandée dans les vignobles... |
