“…Wolbachia strains closely related to w Suz confer resistance to RNA viruses that are otherwise virulent to Drosophila (Hedges et al 2008; Teixeira et al 2008; Osborne et al 2009; Unckless & Jaenike 2012). D. suzukii has a relatively robust immune response, associated with increased hemocyte loads relative to D. melanogaster (Kacsoh & Schlenke 2012); and its largest gene-family expansions and contractions are related to immune response (Chiu et al 2013). Hence, effects of Wolbachia on immune response are natural candidates for the expected fitness benefits we have not yet discovered.…”

“…Since its discovery in Spain in 2008, it has also spread through most of continental Europe (Calabria et al 2012; Cini et al 2012). Given its economic importance and widespread distribution, D. suzukii has become a popular research organism (Hauser 2011), with an annotated genome (Chiu et al 2013). Wolbachia was initially found in Japanese D. suzukii (Cordaux et al 2008).…”

Wolbachiado not live by reproductive manipulation alone: infection polymorphism inDrosophila suzukiiandD. subpulchrella

Drosophila suzukii recently invaded North America and Europe. Populations in Hawaii, California, New York and Nova Scotia are polymorphic for Wolbachia, typically with <20% infection frequency. The Wolbachia in D. suzukii, denoted wSuz, is closely related to wRi, the variant prevalent in continental populations of D. simulans. wSuz is also nearly identical to Wolbachia found in D. subpulchrella, plausibly D. suzukii's sister species. This suggests vertical Wolbachia transmission through cladogenesis (“cladogenic transmission”). The widespread occurrence of 7-20% infection frequencies indicates a stable polymorphism. wSuz is imperfectly maternally transmitted, with wild infected females producing on average 5-10% uninfected progeny. As expected from its low frequency, wSuz produces no cytoplasmic incompatibility (CI), i.e., no elevated embryo mortality when infected males mate with uninfected females, and no appreciable sex-ratio distortion. The persistence of wSuz despite imperfect maternal transmission suggests positive fitness effects. Assuming a balance between selection and imperfect transmission, we expect a fitness advantage on the order of 20%. Unexpectedly, Wolbachia-infected females produce fewer progeny than do uninfected females. We do not yet understand the maintenance of wSuz in D. suzukii. The absence of detectable CI in D. suzukii and D. subpulchrella makes it unlikely that CI-based mechanisms could be used to control this species without transinfection using novel Wolbachia. Contrary to their reputation as horizontally transmitted reproductive parasites, many Wolbachia infections are acquired through introgression or cladogenesis and many cause no appreciable reproductive manipulation. Such infections, likely to be mutualistic, may be central to understanding the pervasiveness of Wolbachia among arthropods.

“…The D. suzukii species subgroup is not traditionally considered monophyletic; however, this interpretation hinges on the exclusion of a single species (D. lucipennis) (Yang et al 2011a). Recent molecular phylogenetic analyses suggest a sister group relationship between SWD and D. biarmipes (Yang et al 2011a;Chiu et al 2013).…”

Invasion biology of spotted wing Drosophila (Drosophila suzukii): a global perspective and future priorities

et al. 2015

The Asian vinegar fly Drosophila suzukii (spotted wing Drosophila [SWD]) has emerged as a major invasive insect pest of small and stone fruits in both the Americas and Europe since the late 2000s. While research efforts have rapidly progressed in Asia, North America, and Europe over the past 5 years, important new insights may be gained in comparing and contrasting findings across the regions affected by SWD. In this review, we explore common themes in the invasion biology of SWD by examining (1) its biology and current pest status in endemic and recently invaded regions; (2) current efforts and future research needs for the development of predictive models for its geographic expansion; and (3) prospects for both natural and classical (=importation) biological control of SWD in invaded habitats, with emphasis on the role of hymenopteran parasitoids. We conclude that particularly fruitful areas of research should include fundamental studies of its overwintering, host-use, and dispersal capabilities; as well as applied studies of alternative, cost-effective management techniques to complement insecticide use within the integrated pest management framework. Finally, we emphasize that outreach efforts are critical to effective SWD management by highlighting successful Communicated by M. Traugott.

“…We used the recently assembled D. suzukii genome (Chiu et al, 2013; project accession number PrJNA213258) as an input for the QDD program (Méglecz et al, 2014) to scan genomic data for microsatellite regions. Briefly, QDD uses four scripts (Sequence similarity, bLAST, microsatellite detection and markers design) to analyze raw data and provide a table summarizing, amongst other, the region of the genome containing a potential microsatellite sequence, the repeat motif and the number of repeats.…”

abstract. Historical and observational data for invasive species are often sparse and incomplete, so molecular genetic markers are increasingly used and have proved to be efficient tools to make inferences about invasion histories. Here, we report the development of 28 polymorphic microsatellite markers in the invasive spotted-wing drosophila, Drosophila suzukii (Matsumura, 1931) (Diptera: Drosophilidae) designed from recent genomics resources, and their cross-amplification in closely related Drosophila species of the su zukii subgroup. The markers, located on autosomal chromosomes, were characterized in two distinct invasive populations from France and Hawaii (USA), and in four sister species of the suzukii subgroup. They all showed substantial polymorphism as well as revealing strong genetic differentiation between the two genotyped populations. These markers represent a promising molecular tool for population genetic studies on D. suzukii, more especially in order to reconstruct the pathways and demographic processes of the world-wide invasion in this major insect pest.
