http://orgprints.org/7509/ The role of intercropping on insects diversity in dryland field crops in a Mediterranean site Caballero, Berta Romero, Albert Perez, Nicolas Ventura, Daniel Chamorro, Lourdes Goula, Marta Sans, F.Xavier Crop health, quality, protection This work aims to evaluate the effect of crop type and density on insects’ community in the Mediterranean re-gion. In winter of 2004, four 35m x 10m blocks (replicates) were delimited and 24 equidistant 2m x 3m plots were marked. Seven crop types (barley, vetch, turnip, barley-vetch, barley-turnip, vetch-turnip and barley-vetch-turnip) at three densities were randomly established within each block. Fifteen crop shoots per plot were randomly collected in May to evaluate insect’s abundance and diversity. Our results suggest that inter-crop has a positive effect on abundance of most exam-ined groups of insects and diversity, specifically when vetch is incorporated in the mixture. Changes in abun-dance of aphids, trips and ants are also discussed connected with vetch presence. 2006 Conference paper, poster, etc. NonPeerReviewed application/pdf http://orgprints.org/7509/1/caballero.pdf Caballero, Berta; Romero, Albert; Perez, Nicolas; Ventura, Daniel; Chamorro, Lourdes; Goula, Marta and Sans, F.Xavier (2006) The role of intercropping on insects diversity in dryland field crops in a Mediterranean site.
