The landscape context of cereal aphid–parasitoid interactions [PDF]

open access: yesProceedings of the Royal Society B: Biological Sciences, 2005
Analyses at multiple spatial scales may show how important ecosystem services such as biological control are determined by processes acting on the landscape scale. We examined cereal aphid–parasitoid interactions in wheat fields in agricultural landscapes differing in structural complexity (32–100% arable land).

Can Mixed Intercropping Protect Cereals from Aphid-Borne Viruses? An Experimental Approach

open access: yesInsects, 2022
Intercropping, i.e., association of two or more species, is promising to reduce insect populations in fields. The cereal aphid Rhopalosiphum padi, a vector of the Barley yellow dwarf virus PAV (BYDV-PAV), represents a major threat for cereal grain ...
