Spotted wing drosophila, Drosophila suzukii Matsumura (Diptera: Drosophilidae), has become a key pest for soft fruits and cherries in Europe in less than a decade since the first outbreak in 2007. Although this pest’s passive dispersal ability has been observed over more than 1400 km in 1 year, active spread has not yet been extensively studied. A mark−release−recapture (MRR) method based on protein-marked flies was employed to determine the flight capacity of D. suzukii. Sterile marked flies were released and recaptured in a trap grid at increasing distances from 10 to 250 m from the releasing point to study flight distance during periods ranging from 3 h to 1 week. MRR experiments were replicated in the presence and absence of host fruits to study how they could affect dispersal behavior. The dispersal capacity of the Mediterranean fruit fly, Ceratitis capitata Wiedemann (Diptera: Tephritidae) was also studied under the same conditions. The results showed a low dispersal ability for D. suzukii, with a daily flight distance below 100 m with no predominant wind. The implications on natural dispersion and control methods based on attractants are discussed.

CONCEPTS
- ceratitis capitata
The Mediterranean fruit fly species included as a comparative dispersal subject under the same experimental conditions.
Aliases: Mediterranean fruit fly, C. capitata
- dispersal behavior
The movement pattern of released flies away from the release point under the tested environmental and resource conditions.
Aliases: dispersal behaviour
- drosophila suzukii
The spotted wing drosophila species that is the focal organism of the dispersal experiments.
Aliases: spotted wing drosophila, D. suzukii
- flight distance
The distance moved by released flies from the point of release over the experimental time window.
Aliases: daily flight distance
- host fruits
Fruit resources present or absent in the experiments to test how food or oviposition sites affect movement.
- mark-release-recapture technique
A movement-assessment method in which marked individuals are released and later recaptured to infer dispersal.
Aliases: MRR, mark-release-recapture method
- protein-marked flies
Flies labeled with a protein marker so they can be identified after release and recapture.
Aliases: sterile marked flies
- trap grid
An arrangement of traps placed at set distances from the release point to capture released flies.
