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).

Generalist predators disrupt parasitoid aphid control by direct and coincidental intraguild predation [PDF]

open access: yes, 2011
Generalist predators and parasitoids are considered to be important regulators of aphids. The former not only feed on these pests, but might also consume parasitoids at all stages of development.

The combined impacts of wheat spatial position and phenology on cereal aphid abundance [PDF]

open access: yesPeerJ, 2020
Background Wheat is a staple crop that suffers from massive yield losses caused by cereal aphids. Many factors can determine the abundance of cereal aphids and the damage they cause to plants; among them are the plant’s genetic background, as well as ...
