“…The spotted wing drosophila, Drosophila suzukii , is an invasive species that is now spread in West and East Europe ( Calabria et al, 2012 ; Lavrinienko et al, 2017 ) as well as in North and South America ( Hauser, 2011 ; Lavagnino et al, 2018 ; see also Asplen et al, 2015 for a review). Contrary to other drosophilids, D. suzukii females lay eggs in mature fruits.…”

Cold Acclimation Favors Metabolic Stability in Drosophila suzukii

et al. 2018

The invasive fruit fly pest, Drosophila suzukii, is a chill susceptible species, yet it is capable of overwintering in rather cold climates, such as North America and North Europe, probably thanks to a high cold tolerance plasticity. Little is known about the mechanisms underlying cold tolerance acquisition in D. suzukii. In this study, we compared the effect of different forms of cold acclimation (at juvenile or at adult stage) on subsequent cold tolerance. Combining developmental and adult cold acclimation resulted in a particularly high expression of cold tolerance. As found in other species, we expected that cold-acclimated flies would accumulate cryoprotectants and would be able to maintain metabolic homeostasis following cold stress. We used quantitative target GC-MS profiling to explore metabolic changes in four different phenotypes: control, cold acclimated during development or at adult stage or during both phases. We also performed a time-series GC-MS analysis to monitor metabolic homeostasis status during stress and recovery. The different thermal treatments resulted in highly distinct metabolic phenotypes. Flies submitted to both developmental and adult acclimation were characterized by accumulation of cryoprotectants (carbohydrates and amino acids), although concentrations changes remained of low magnitude. After cold shock, non-acclimated chill-susceptible phenotype displayed a symptomatic loss of metabolic homeostasis, correlated with erratic changes in the amino acids pool. On the other hand, the most cold-tolerant phenotype was able to maintain metabolic homeostasis after cold stress. These results indicate that cold tolerance acquisition of D. suzukii depends on physiological strategies similar to other drosophilids: moderate changes in cryoprotective substances and metabolic robustness. In addition, the results add to the body of evidence supporting that mechanisms underlying the different forms of acclimation are distinct.

“…Posteriormente se detectó su presencia en Brasil en 2014 (Deprá et al, 2014) y Chile en 2015 (Medina-Muñoz et al, 2015). En Argentina esta especie se citó por primera vez en Río Negro en 2015 atacando frambuesa (Cichón et al, 2015) y luego el mismo año fue detectada en Entre Ríos en trampas en cultivos de naranja (Díaz et al, 2015;Lavagnino et al, 2018) y en Buenos Aires sobre arándanos (Santandino et al, 2015).…”

“…The infestation of a variety of commercial fruits by the highly invasive fruit fly, spotted wing drosophila (SWD) Drosophila suzukii Matsumura (Diptera: Drosophilidae), recently detected in North America (Goodhue et al, 2011;Hauser, 2011;Lee et al, 2011;Walsh et al, 2011), South America (Depra et al, 2014;Andreazza et al, 2016;Lavagnino et al, 2018), and Europe (Calabria et al, 2012;Cini et al, 2014;Poyet et al, 2014;Aabanowska and Wojciech, 2015;Briem et al, 2015;Mazzetto et al, 2015;Radonjic and Hrncic, 2015;Arno et al, 2016;Hamby et al, 2016;Briem et al, 2018) is the cause of great concern because of its economic impact (Goodhue et al, 2011;Walsh et al, 2011;Cini et al, 2012;Farnsworth et al, 2017). To combat D. suzukii, many preventive studies, such as attractant identification (Cha et al, 2012;Landolt et al, 2012;Kleiber et al, 2014;Abraham et al, 2015;Cha et al, 2015;Mazzetto et al, 2016;Feng et al, 2018;Jaffe et al, 2018;Zhang and Feng, 2019), trap comparison (Lee et al, 2012;Lee et al, 2013;Iglesias et al, 2014;Renkema et al, 2014;Kirkpatrick et al, 2016), management methodology (Cuthbertson et al, 2014;Hampton et al, 2014;…”

Controlled-Release Dispenser and Dry Trap Developments for Drosophila suzukii Detection

et al. 2020

The spotted wing drosophila (SWD), Drosophila suzukii, is an exotic vinegar fly originating from SouthEast Asia and has invaded many American and European countries. This devastating pest has caused severe damage on soft-skinned fruit crops, which has resulted in large economic losses. Although many D. suzukii detection devices have been developed and used by growers/farmers in orchards, most of them did not meet their expectation. More simple, convenient, and efficient detection tools are still urgently needed so that growers/farmers can make timely management decision. In our previous study a quinary blend, containing acetoin, as a long-range, and ethyl octanoate, as a short-range attractant for SWD, had been identified. In this study, a controlled-release polyethylene dispenser containing five identified attractants: acetoin, ethyl octanoate, ethyl acetate, phenethyl alcohol, and acetic acid, was tested in laboratory conditions for release rates, as well as in a blueberry field and an adjacent wooded area for trapping activity. Release of the most D. suzukii attractants from the polyethylene dispenser was constant. In the laboratory, release rates of ethyl acetate (0.3 g/day over 14 days), phenethyl alcohol (0.0054 g/day over 36 days), and acetic acid (0.13 g/day over 36 days) followed zero order kinetics. Acetoin and ethyl octanoate were blended together and had a varied release rate. In the field, dry and liquid traps baited with the optimized controlled-release dispenser were evaluated and compared with liquid traps baited with apple cider vinegar (ACV). During blueberry harvest season in 2018, the liquid traps containing drowning solution baited with the optimized controlledrelease dispenser caught both male and female D. suzukii 2 weeks earlier and had significantly higher selectivity than that of ACV traps in the field. Additionally, in 2019 field tests, dry traps baited with the controlled-release dispenser demonstrated earlier detection compared to the ACV traps. Due to the simplicity of the dry trap design and easy processing, it has great potential to be an efficient and convenient D. suzukii detection tool for growers/farmers.
