Plant diversification impact on the oviposition response of a predatory bug in a laboratory set‐up Open
Crop diversification can improve biological pest control, by providing resources and habitat to enhance the performance of natural enemies. The polyphagous black bean aphid ( Aphis fabae ) is a major pest in sugar beet and also an importan…

Plant resistance induced by hemipterans — Effects on insect herbivores and pathogens Open
Damage to a host plant caused by insect herbivory and pathogens induces defence responses in the plant. Defence responses induced by hemipterans are often distinct from those elicited by chewing herbivores. Furthermore, hemipterans and pat…

Effects of strawberry resistance and genotypic diversity on aphids and their natural enemies Open
Ecological theory hypothesizes that plant trait diversity may be as important as the presence of specific functional traits (e.g., resistance) for the herbivore and predator communities within a population. We used experimental populations…

The impact of reduced tillage and distance to field margin on predator functional diversity Open
Introduction Agricultural intensification results in biodiversity loss through land conversion and management practices which negatively impact arthropods. The abundance and diversity of ground-dwelling predators, e.g. ground beetles (Cole…

Large-scale geography survey provides insights into the colonization history of a major aphid pest on its cultivated apple host in Europe, North America and North Africa Open
With frequent host shifts involving the colonization of new hosts across large geographical ranges, crop pests are good models for examining the mechanisms of rapid colonization. The microbial partners of pest insects may also be involved …
