Abstract

In agroecosystems a large number of plant protection products (PPP) are commonly used. During their application a fraction of them reaches the soil and thus the soil community is exposed to active ingredients. In the field, biotic and a-biotic factors may affect the response to dangerous substances. Environmental conditions may modify the bioavailability of chemicals. Biological communities are exposed to complex mixtures of toxicants with different target organisms and mode of action. Environmental factors (e.g. temperature, moisture) and their fluctuations may act as additional stressors for the community. Interactions among populations and indirect effects due to changes in the community structure are further increasing the complexity of the response. In this study a microarthropod community was studied in a year-round monitoring campaign in a vineyard in Northern Italy. The environmental conditions were just monitored and not altered in any way, i.e. PPP were applied as in normal agricultural practice. Detailed information on pesticide applications and on major meteorological conditions and environmental parameters was collected. Three sampling points in a decreasing exposure gradient were selected (among the rows, 4 m and 10 m away from the last row). Exposure was estimated for the three points. The fluctuations of the community during the year were studied, also using multivariate statistical analysis. A decreasing abundance inside the vineyard after pesticide application was evident and major changes in the composition of the community, related to direct and indirect effects, were identified. Differences in recovery after the productive season between the community inside and outside the vineyard were observed, and the possible causes will be discussed.
