Spatial distribution of an arthropod community in a pear orchard (southern France)

This study analysed specific features of the spatial distribution of a global population of arthropods in an experimental orchard of pear trees, null Pyrus communis null (L.), in southern France. Insect fauna was sampled by regular beating of the 210 trees in the experimental orchard from spring to autumn in three consecutive years (2004–2006). This orchard, where no chemical treatments had been applied since 2000, is bordered to the north by a...
