Abstract
A drastic reduction in pesticide use is necessary to better and more feed the population, and to be competitive, less intensive agricultural systems must increasingly rely on integrated pest management strategies, including biological control by conservation. This experiment allows the long-term study of predation of pests (exposure of sentinel prey) and auxiliary carabid communities present in 20 fields along a gradient practices (organic or conventional agriculture) and landscape. An important temporal variability of these gradient’s effects has occurred. An important effects of temporal variability of these gradients has occurred. In particular, the diversity...
