Abstract
Simple SummarySpotted-wing drosophila, Drosophila suzukii, is one of the most important invasive pests of fruit and wine production worldwide. This species feeds on cherry, raspberry, blackberry, blueberry, strawberry, peach, plums, grape, and other soft fruits. It causes significant damage because, unlike most other Drosophila species, it oviposits and feeds on healthy fruits. Drosophila suzukii is native to East Asia and has been rapidly spreading through Europe, where it is considered a quarantine pest, since 2008. Herein, we report the first records of spotted wing drosophila in European Russia. In 2017 and 2020, we placed baited traps in different districts of the resort city of Sochi (Black sea Coast of the Caucasus, Krasnodar Territory, Russia) and collected 49 adults of this species. They were identified by the typical female ovipositor, spotted wings of the males, and other characters. Krasnodar Territory is one of the main fruit-producing regions of Russia. Therefore, populations of this pest should be monitored and measures to minimize economic damage should be taken.Spotted-wing drosophila Drosophila suzukii (Matsumura) is one of the most important invasive pests of fruit and wine production worldwide. This species feeds on Prunus spp., Rubus spp., Fragaria spp. (Rosaceae), Vaccinium spp. (Ericaceae), Vitis spp. (Vitaceae), and other soft fruits. It causes significant damage because, unlike most other Drosophila species, it oviposits and feeds on healthy fruits. Drosophila suzukii is a quarantine pest that is included on the European and Mediterranean Plant Protection Organization (EPPO) A2 List. This species is native to East Asia and has been rapidly spreading through Europe since 2008. Herein, we report the first records of D. suzukii in European Russia. In 2017 and 2020, we placed baited traps in different districts of the resort city of Sochi (Black sea Coast of the Caucasus, Krasnodar Territory, Russia). Three specimens of D. suzukii were collected in June 2017, two specimens in September 2017, and 44 specimens in September 2020. Specimens were identified by the typical female ovipositor, spotted wings of the males, and other morphological characters. Krasnodar Territory is one of the main fruit-producing regions of Russia. Therefore, populations of this pest should be monitored and measures to minimize economic damage should be taken.
Highlights
The rapid spread of invasive pests is a great economic and ecological problem of the 21st century [1]
An unusually high number of invasive pests new to European Russia were first detected in the subtropics of the Russian Caucasus, namely in the city of Sochi in the last 10–20 years
D. suzukii will oviposit and develop in healthy ripening soft fruits. This increases the danger of D. suzukii to human health, as the consumption of what appear to be normal fruits that contain drosophila larvae can lead to conditions such as intestinal myiasis
Summary
The rapid spread of invasive pests is a great economic and ecological problem of the 21st century [1]. An unusually high number of invasive pests new to European Russia were first detected in the subtropics of the Russian Caucasus, namely in the city of Sochi in the last 10–20 years. This region is associated with an increase in international trade, especially bulk imports of planting material from. Spotted-wing drosophila, Drosophila suzukii (Matsumura, 1931), is one of the most important invasive pests of fruit and wine production worldwide [3] This species damages cherry, peach, and plums (Prunus spp., Rosaceae); raspberry and blackberry (Rubus spp., Rosaceae), strawberry (Fragaria spp., Rosaceae); blueberry (Vaccinium spp., Ericaceae); grape (Vitis spp., Vitaceae); and other soft fruits. This increases the danger of D. suzukii to human health, as the consumption of what appear to be normal fruits that contain drosophila larvae can lead to conditions such as intestinal myiasis
