Island invasions by the non-native vinegar fly Drosophila suzukii and its parasitoid wasps

Paul K. Abram, E. H. Beers, Charles C. Coslor, Benjamin Diehl, Michelle T. Franklin, Louis B. Nottingham, Jason Thiessen, Matthew Tsuruda, Juli Carrillo

The paper examines the distribution of Drosophila suzukii and its parasitoids across islands, finding that parasitoids are less common and do not suppress host populations effectively.

The realized host specificity of Leptopilina japonica and Ganaspis kimorum, adventive larval parasitoids of the invasive Drosophila suzukii

Paul K. Abram, Jessie Moon, Jessica L. Fraser, Jason Thiessen, Tara D. Gariépy

This study documents the field-based host specificity of two non-native parasitoids of Drosophila suzukii, finding G. kimorum is highly specific while L. japonica uses additional host species.
