First record of Drosophila suzukii in Quebec vineyards

Aim: Surveys conducted between July and September 2012 in Quebec vineyards revealed the presence of the spotted wing drosophila (SWD), Drosophila suzukii Matsumura, just before harvest.Methods and results: Red and white grapevine cultivars from four vineyards were surveyed for leafhoppers by using a tapping method. Unexpectedly, a total of 30 SWD adults were collected from red grapevine cultivars, i. e., Marechal Foch, Gamay and Seyval Noir. Furthermore, a total of 101 SWD emerged from bunches selected in these vineyards and placed under laboratory conditions. No SWD were found in white cultivars.Conclusion: This is the first mention of SWD in grapevines grown for wine in Quebec.Significance and impact of the study: Spreading of SDW across Quebec vineyards may lead to important yield losses. Insecticide treatments need to be adapted to address this new entomological challenge.

Here we report on the first peculiar detection of the spotted-winged drosophila, Drosophila suzukii (Matsumura) on Martín García Island, a wildlife refuge located in the Río de la Plata estuary, Argentina. Flies were collected using banana baited traps fermented with live yeast, in sandy areas with abundant presence of cactus in the interior of the island. The absence of cultivated host plants, e.g., fruit crops, and the small population of humans inhabiting the island make the presence of D. suzukii in this wildlife refuge unexpected. Previous detection of this fly in South America happened mostly within commercial fruit orchards and/or neighboring fields.

First Time

The spotted wing drosophila Drosophila suzukii Matsumura (Diptera: Drosophilidae) is an invasive pest originating from Southeast Asia. It was detected for the first time in Europe in 2008 (Spain and Italy) and subsequently in other European countries. It is a highly polyphagous pest that infests healthy, ripening fruit and presents a serious threat to fruit production, particularly of soft skinned fruit. In the first half of October 2013, a new fruit fly species was unexpectedly detected in Tephri traps baited with the three-component female-biased attractant BioLure that is regularly used for monitoring the Mediterranean fruit fly Ceratitis capitata Wiedem. (Diptera: Tephritidae) in Montenegro. Brief visual inspection identified the new species as the spotted wing drosophila D. suzukii. The pest was first recorded in several localities on the Montenegrin seacoast around Boka Kotor Bay. After the finding, all Drosophila specimens were collected from traps for further laboratory observation. A quick follow-up monitoring of other Tephri traps was carried out within the next few days on the rest of the seacoast (localities from Tivat to Ulcinj). Additionally, Tephri traps were set up around Lake Skadar and in the city of Podgorica, as well as on fresh fruit markets in Podgorica. The results of this preliminary study showed that D. suzukii was present in all surveyed locations and adults were captured until late December. Both sexes were found in traps with BioLure. Our data show that D. suzukii is present in southern parts of Montenegro and there is a serious threat of its further spreading, particularly towards northern parts of the country where the main raspberry and blueberry production is placed. The results also show that Tephri traps baited with BioLure can be used for detection and monitoring of spotted wing drosophila.

Berry Crops

Abstract Minnesota was dubbed the ‘raspberry consumption capital of America’ in 2017 by wholesaler Driscoll’s, Inc. Local production of this high-demand fruit, however, is limited by the invasive pest, spotted wing Drosophila (Drosophila suzukii Matsumura, Diptera: Drosophilidae). Recent research to develop integrated pest management (IPM) programs for MN berry crops indicates that raspberry growers are particularly vulnerable to significant spotted wing Drosophila-related yield losses. Spotted wing Drosophila was detected in Minnesota in 2012 across 29 counties. This analysis explores the economic impact of raspberry yield losses associated with spotted wing Drosophila in Minnesota as part of a multifaceted research initiative. An electronic survey of 157 MN berry growers was conducted in November 2017. Eighty-two individual grower surveys were returned (52% response rate). The survey included questions about production acreage, marketing practices, spotted wing Drosophila-related yield losses and future production intentions. The results of the e-survey indicate that raspberry growers have borne the highest levels of infestation among MN fruit growers surveyed. Spotted wing Drosophila-related yield losses for raspberry growers ranged from 2 to 100% of planted acreage.The median yield loss for this group of growers was 20% in 2017. Applying the median yield loss to ex-ante production estimates, we conclude that MN growers lost approximately $2.36 million in raspberry sales during the 1 yr studied. Investing in spotted wing Drosophila control measures will help MN growers reduce some of these losses in the future.
