Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) is a fruit fly from Asia that has significant economic importance. It attacks various species of thin-skinned fruit such as strawberries, cherries, raspberries and blueberries. Unlike other flies of the genus Drosophila, its serrated ovipositor enables it to lay eggs in healthy fruit, making it a major fruit pest before harvesting.

Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) is a fruit fly from Asia that has significant economic importance. It attacks various species of thin-skinned fruit such as strawberries, cherries, raspberries and blueberries. Unlike other flies of the genus Drosophila, its serrated ovipositor enables it to lay eggs in healthy fruit, making it a major fruit pest before harvesting. In Europe, the first damage was recorded in Italy in 2009. In Spain, the presence of this pest was first confirmed in cherry crops in Catalonia in 2011, although damage consistent with that described for D. suzukii had previously been detected in strawberries and attributed to Drosophila melanogaster. The impact of this pest has burgeoned since then. Currently, D. suzukii is present in various regions of Spain, and it is spreading rapidly in several European countries. In addition to its area of origin, it is also present in the United States and Brazil. 
The highest populations are recorded in spring and particularly in autumn, whereas in winter and summer it is almost nonexistent. This is primarily because the activity of this pest is closely linked to favourable climatic conditions such as high humidity and mild temperatures. Current control measures are based on monitoring adult populations with food traps and using insecticides. Studies are also being carried out on the possibility of using mass trapping and on the role of native natural enemies in its control. Other studies underway aim to ascertain the effectiveness of using mesh screens to prevent damage from this pest.
