| Aphid populations, including a widespread pest, Myzus persicae, are known to be affected by cultural practices, plant growth and natural regulation, but their control in orchards most frequently relies on regular treatments aiming to avoid direct damage and virus transmission. This study aimed first at characterising farmers’ management strategies towards aphids and, secondly evaluating them in terms of efficiency and impact on aphid natural enemies from 19 organic and conventional fruit farms in south-eastern France. Comprehensive variables made it possible to differentiate four strategies: intensive, optimised, input-substitution and integrated. The more integrated the strategy, the more diverse and abundant the aphids. The two most effective strategies... |

| Peach production in the Rhône-Alps region is increasingly challenged by mediterranean European regions. A possible regional strategy would consist in the development of qualification signs. A significant part of the peach production is already labelled (CCP, Red Label, Organic). How such labels relate with quality attributes at field level ? Can polyphenols be considered as an asset in a re-qualification process of peach production? To contribute to these issues, we present preliminary results derived from field work in Rhône-Alps. The study was conducted on 12 orchards of yellow peach (cv Spring Lady) in farms. 10 orchards were managed according to the above mentioned specifications while 2 were cultivated without specifications. Farmers practices... |
