Conversely, parasitoid Hymenoptera constituted prevailing group arboreal habitat C MD orchards. highest diversity evenness indices were unexpectedly measured orchard. richness opposite found canopy, lowest values being Depending year, sampling period vegetation strata (apple or cover), either closer
