Summary: Agriculture as a productive activity can affect the deterioration or preservation of the environment and itÂ’s natural resources. These resources, soil, water, etc.., are essential inputs for agriculture. Their degradation can eventually compromise the productive potential and thereby constitute a major economic problem. Conventional agriculture is questioned by its negative effects on the degradation of the natural resources it use, the local biodiversity and the environment in general. At the time, alternative systems of agricultural production usually called sustainable agriculture, like agroforestry, are growing stronger. In agro-ecosystems, the presence and persistence of culture beneficial insects depends on the availability of prey within the same plots (as agroforestry). In 2010, the influence of the environment including the effects induced by agroforestry on Carabidae and Syrphidae populations was studied in wheat plots. A higher abundance was observed in the agroforestry plot at the trapping line located 10m from the grass strip on which the trees are planted. This result indicates a positive trend in 2010 for biodiversity induced by the introduction of agroforestry.
