Metabolic consequences of various fruit-based diets in a generalist insect species

This study investigates the metabolic responses of Drosophila suzukii to diverse fruit diets, finding a generic metabolic response and accumulation of diet-specific compounds.

Rapid and transient evolution of local adaptation to seasonal host fruits in an invasive pest fly

This study shows that local adaptation, not phenotypic plasticity, dominates in Drosophila suzukii populations adapting to changing host fruits over generations.

Adaptation and correlated fitness responses over two time scales in Drosophila suzukii populations evolving in different environments

This study tracks fitness changes in Drosophila suzukii populations across multiple generations and environments, revealing how adaptation dynamics differ over time.

How do invasion syndromes evolve? An experimental evolution approach using the ladybird Harmonia axyridis

This study uses artificial selection on H. axyridis to investigate how invasion syndromes evolve, finding that selecting on age at first reproduction leads to more widespread phenotypic changes than selecting on body mass.
