“…It is thus possible that other unknown chemical traits might also affect larval performance. Overall, our results are consistent with other reported studies that grapes are not good reproductive hosts for D. suzukii [49,50,51,52,53,54,55,56,57,69].…”

“…We did not observe grape infestation in our field collections, and our laboratory trials showed a low survival rate of D. suzukii offspring on grapes when compared to other fruits (Table 3). The oviposition susceptibility and offspring survival could vary among varieties or cultivars due to the variations in skin hardness and chemical properties [49,50,51,52,53,54,55,56,57,69]. For example, Ioriatti et al [53] demonstrated that oviposition increased consistently as the skin hardness of the grape decreased.…”

“…For example, the potential impact of D. suzukii on wine grapes in Italy was discussed by Ioriatti et al [49], who observed D. suzukii oviposition in soft-skinned berries, and, in Japan, some grape cultivars were reported as hosts for D. suzukii [7]. In Oregon, Lee et al [9] found that D. suzukii was able to successfully oviposit in some wine grape cultivars but that offspring survival was low (<10%), whereas other studies observed no or low levels of infestation of intact grapes in the field or laboratory [50,51,52,53,54,55,56,57]. Some of the initial work in Japan reported that D. suzukii emerged only from fallen and damaged apple, apricot, loquat, peach, pear, persimmon and plum [7], but Sasaki and Sato [58] reported that healthy peach fruit can be infested.…”

A major challenge to the area-wide management of Drosophila suzukii is understanding the fly’s host use and temporal dynamics, which may dictate local movement patterns. We determined D. suzukii’s seasonal host use in California’s San Joaquin Valley by sampling common crop and non-crop fruits in a temporal sequence of fruit ripening. We then evaluated the suitability of selected fruits as hosts. Drosophila suzukii emerged from both intact and damaged cherries during the cooler, early season period. Fly density remained low through the hot spring–summer period and re-surged as temperatures lowered in fall when the fly did not cause damage to intact peach, nectarine, plum, pear, grape, pomegranate, apple, persimmon and citrus (in order of ripening) but did emerge from the damaged fruits of these crops. The fly also emerged from two ornamental fruits (loquats and cactus) but was not found on wild plum and two endemic wild fruits (buckthorn and bitter berry). Drosophila suzukii completed development (egg to adult) on cactus, mandarin carpel, pomegranate seed, wild plum and buckthorn at survival rates similar to cherry (51.2–68.8%), whereas it had a lower survival rate on bitter cherry (33.2%), table grape (31.5%), raisin grape (26.5%), and wine grape (4.5%). The high acidity levels of grapes negatively affected the fly’s fitness. Among 10 cherry cultivars, survival rate was not affected by sugar content, but it decreased with increasing egg density per gram of fruit. Results suggest that in California’s San Joaquin Valley, the early season crops are most vulnerable, summer fruits ripen during a period of low pest pressure, and late season fruits, when damaged, serve to sustain D. suzukii’s populations in this region.

“…Sugar (brix) level was also not a significant factor (P = 0.211) for the susceptibility of wine grapes exposed artificially in the laboratory. These results are supported by other studies with table or wine grapes that likewise found no correlation between brix levels and D. suzukii infestations (Lee et al 2011a;Pelton et al 2017;Rezazadeh et al 2018). For damaged table grapes from the field, our data did show a negative correlation between D. suzukii infestations and increasing brix levels and a positive correlation between increasing brix levels and higher infestations by other Drosophila species (Fig.…”

“…We were able to rear small numbers of D. suzukii from only 17% of the intact wine grape samples artificially exposed in the laboratory (Table 6), further showing that wine grapes are a poor host. Based on a study with bunch and Muscadine grapes, Rezazadeh et al (2018) concluded that grapes are generally not preferred oviposition hosts for wild or caged D. suzukii. In Switzerland, D. suzukii were found at very low levels only in red cultivars and nearly always in association with other Drosophila species (Linder et al 2014).…”

Monitoring of Drosophila suzukii (Diptera: Drosophilidae) in Okanagan Valley vineyards, British Columbia, Canada, and assessment of damage to table and wine grapes (Vitaceae)

Spotted-wing drosophila, Drosophila suzukii, (Matsumura) (Diptera: Drosophilidae), has become a serious pest of soft fruit in the Okanagan Valley of British Columbia, Canada since its detection in 2009. The study was conducted to determine the distribution of D. suzukii and damage levels in grapes. Apple cider vinegar-baited traps placed in table and wine grape (Vitis vinifera Linnaeus; Vitaceae) vineyards during 2011–2013 demonstrated that D. suzukii was numerous in all sites, with earliest emergence and highest numbers recorded in 2013. Drosophila suzukii were reared from intact and damaged table grapes and damaged wine grapes collected from the field, but not from intact wine grapes. Drosophila suzukii were reared in low numbers in 2011 from intact fruit of 11 wine grape cultivars exposed artificially in the laboratory. Susceptibility of intact wine grapes under laboratory conditions in 2011 when sour rot was widespread might relate in part to undetected infections of berries due to weather conditions. Identification of Drosophila Fallén species revealed that D. suzukii comprised a small portion of the total. Our results demonstrate that healthy wine grapes in the Okanagan Valley of British Columbia are largely undamaged by D. suzukii, while certain table grape cultivars should be protected from attack.

Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) also known as spotted-wing drosophila (SWD), is a pest native to Southeast Asia. In the last few decades, the pest has expanded its range to affect all major European and American fruit production regions. SWD is a highly adaptive insect that is able to disperse, survive, and flourish under a range of environmental conditions. Infestation by SWD generates both direct and indirect economic impacts through yield losses, shorter shelf life of infested fruit, and increased production costs. Fresh markets, frozen berries, and fruit export programs have been impacted by the pest due to zero tolerance for fruit infestation. As SWD control programs rely heavily on insecticides, exceedance of maximum residue levels (MRLs) has also resulted in crop rejections. The economic impact of SWD has been particularly severe for organic operations, mainly due to the limited availability of effective insecticides. Integrated pest management (IPM) of SWD could significantly reduce chemical inputs but would require substantial changes to horticultural management practices. This review evaluates the most promising methods studied as part of an IPM strategy against SWD across the world. For each of the considered techniques, the effectiveness, impact, sustainability, and stage of development are discussed.
