Aphis fabae Scopoli and Myzus persicae Sulzer (Hemiptera: Aphididae) are economically important pests of sugar beet. Natural enemies have potential for pest regulation. However their contribution to the control of the two sugar beet aphids is poorly understood. To elucidate the trophic relationships, we selected three aphid predators for molecular gut content analysis: two generalists Cantharis lateralis L. (Coleoptera: Cantha...

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 (Coleoptera: Carabidae) and spiders (Araneae), are negatively affected by soil disturbances such as tillage. Reducing soil disturbances can potentially conserve arthropod populations in the field...

The strawberry blossom weevil (SBW), Anthonomus rubi , is a major pest in strawberry fields throughout Europe. Traps baited with aggregation pheromone are used for pest monitoring. However, a more effective lure is needed. For a number of pests, it has been shown that the attractiveness of a pheromone can be enhanced by host plant volatiles. The goal of this study was to explore floral volatile blends of different strawberry s...
