Hoverflies in organic apple orchards in north-western Italy Organic Eprints
Rossi, Jacopo; Gamba, Ursula; Pinna, Massimo; Spagnolo, Sandra; Visentin, Cristina; Alberto, Alma.
A list is given of hoverflies collected by means of Malaise and white sticky traps in two organic apple orchards in north-western Italy. The total number of collected species was 17 and it was compared with literature, in order to discuss differences due to sampling methods. The predominant species collected were Sphaerophoria scripta (L.) (73% of the total sample) and Eupeodes corollae (F.) (14%). The trend of adult captures of this species is drawn and discussed. Data on wild plant species in the orchards are also given.

Pest management and biodiversity in organic fruit production: the case of apple orchards Organic Eprints
SAUPHANOR, B.; SIMON, S.; BOISNEAU, C.; CAPOWIEZ, Y.; RIEUX, R.; BOUVIER, J.C.; DEFRANCE, H.; PICARD, C.; TOUBON, J.-F..
Numerous pesticide applications are required for orchard protection, regardless of the guidelines. Organic fruit production (OFP) mainly relies on the use of mineral fungicides and microbiological or naturally-occurring insecticides. The environmental impact of this type of production does not significantly differ from that of conventional production when assessed in terms of synthetic indicators. However, the abundance of earthworms, as well as the abundance and specific richness of arthropod pests and beneficials in the orchards and surrounding hedges, is greater in OFP than in conventional orchards. Generalist predators are usually less affected by OFP compounds than by the chemical pesticides applied in conventional orchards. OFP also benefits avian...
