Fauna and associations of aphid parasitoids in an up-dated farmland area (Czech Republic)
Bulletin of Insectology 61 (2), 251-276
Abstract: A structural analysis of the parasitoid-aphid-plant associations related to their occurrence in different habitats and periods of the season in a model area (Pacov and environs, Czech Republic) is presented. The information was obtained between 1958-2007 and it was derived from aphid/plant samples taken in the field and reared for parasitoids in the laboratory. Three periods, in the course of 1958-2007 (1958-1990, 1991-1999, 2000-2007), were compared, but no significant differences in the native tritrophic structures of associations were determined. However, apparent changes were found due to the impact of some invasive plant and aphid species (listed) and subsequent interactions in the communities. The results are discussed in relation to the environmentally friendly approaches to the landscape management.
