Meadows and pastures play a vital economic role for both agriculture and tourism along the Southern side Alps. The main objective of the PRAMIG (Miglioramento dei prati a Sud delle Alpi) project was to promote sustainable management methods for farms located in the Southern side Alps, by means of a fodder production system adapted to the local conditions, as well as suited to the animals' needs and manageable by the peasant families. For three years, key stakeholders (AGRIDEA, APF, ACW, Agricultural Extension of TI, Agricultural School of Mezanna, SEREC) run demonstrative tests and trials on ten farms, follow the pheno-logical development of meadows, measure the growth of grass and characterize the vegetation of permanent grasslands. Disseminated in the usual channels, such as extension days, specialized agricultural press and datasheets, the results of such an approach led to better evaluate the main characteristics of grassland areas in the Southern Alps, and to identify the operating practices and interventions best suited to develop their potentials. This project has revived the debate on forage (especially in mountain areas) and encouraged stakeholders to build and strengthen their network of partnerships at different levels (agricultural, institutional).

BACKGROUND: Drosophila suzukii is a highly polyphagous vinegar fly native to Asia, which invaded Switzerland in 2011. The pest was found in all regions of the country, from low altitudes to the timberline. Due to its fast reproduction rate and the infestation of fruits shortly before harvest D. suzukii is difficult to control. OBJECTIVE: Our main objective was to establish an efficient monitoring campaign all over Switzerland. RESULTS: In 2012, a total of 60,000 D. suzukii were captured in 200 monitoring traps, whereupon it represented between 25 and 75% of all vinegar flies trapped. The range of host plants is very broad, not only affecting crops, but also wild fruits. In 2012 most individuals were captured close to or within cultivated raspberry, blackberry and grapevine as well as in wild shrubs such as elderberry. It is likely that as a result of a consequent application of the recommended sanitation measures, only very few cases of economic damage were reported by the producers in 2012. CONCLUSIONS: Monitoring traps can reliably detect the occurrence of the pest in a region. The trap must be very selective to small insects (diameter of 3 mm) to avoid other beneficial insects such as Lepidoptera and Hymenoptera being caught. In case of local presence, setting up a dense net of mass-traps around the crop or between a hedge and the crop should guarantee capture of most vinegar flies before they attack ripe fruits. In close collaboration with national and international partners, Agroscope will try to identify pragmatic and sustainable crop protection measures against D. suzukii. © 2014 - IOS Press and the authors.
