Mortality of flies exposed to cyazypyr was relatively low after 16 hours but caused intermediate mortality after 40 hours. Some work has been conducted on the normal temperature ranges at which D. suzukii can develop and reproduce (Tochen et al., 2014). Although considered native to East Asia, it is possible that D. suzukii is not native to Japan but was introduced into the country at the turn of the century. Drosophila suzukii.

Drosophila suzukii attacking commercial fruit in Western USA were confirmed by an Oregon Department of Agriculture pest alert (ODA 2009). There are differences in fruit susceptibility within species and among varieties within the same fruit species (Lee et al., 2011). Consequently there are neither official limits on the movement of host crops from infested areas, nor coordinated actions for monitoring its presence in new areas. First findings of Drosophila suzukii. Research into the Fruit-fly Drosophila suzukii Matsumura (Preliminary Report). First record of Drosophila suzukii in Quebec vineyards. D. suzukii seems to have important relationships with forests and woodland, where it can find a suitable microclimate and host plants year-round (Grassi et al, 2011). Journal of Economic Entomology, 106(4):1932-1937, Andreazza F, Haddi K, Oliveira E E, Ferreira J A M, 2016. Apple cider vinegar was one of the first baits used because it was effective and practical to use (EPPO, 2013a). Laboratory bioassays found that flies were attracted to dark colours, ranging from red to black, and that the use of three alternating red, black and red coloured strips significantly increased the number of flies caught (Basoalto et al., 2013). Tolfenpyrad had relatively good activity by topical exposure, but residual activity has yet to be determined. In this study, population dynamics of D. suzukii and its associated parasitoids were investigated. For more information on traps and baits, see the Monitoring and Surveillance section in Prevention and Control. ©Dr Gevork Arakelian/Dept. However, the active ingredients are not very persistent. Olfaction and gustation play a critical role during insect niche formation, and these senses are largely mediated by two important receptor families: olfactory and gustatory receptors (Ors and Grs). Originating in China, D. suzukii was first described in 1931 in Japan and first appeared in Europe in 2009 in northern Italy (Trentino Alto Adige). A detailed historic account of the dispersion of D. suzukii outside of its native area is given in Hauser (2011). IOBC/WPRS Bulletin. Grassi A, Pallaoro M, 2012.

Since its detection in 2008 in California [ 1 ] and Spain [ 2 ], it has become established in North America and in many European countries. Organic crop production is seriously threatened by D. suzukii as only a few natural insecticides are allowed. The pupal ectoparassitoid P. vindemiae has also been found in association with D. suzukii in orchards and vineyards, both in USA and in Europe (Brown et al., 2011; Rossi Stacconi et al. (Plodova vinska mušica - Drosophila suzukii (Matsumura).). DOI:10.1603/IPM12012. Annot. Moreover, the efficacy of the current available insecticides against D. suzukii larvae within fruits is limited, and D. suzukii control is focused on treatments based on chemicals targeting adults (Cini et al., 2012).

D. suzukii adults are 2-3 mm long with red eyes, a pale brown or yellowish brown thorax and black transverse stripes on the abdomen. While parasitization by L. heterotoma induced a decrease in the number of circulating haemocytes in D. melanogaster, it led to a large increase in the total haemocyte counts of D. suzukii (Poyet et al., 2013). A polyphagous pest, it infests a wide range of fruit crops, included grape, as well as an increasing number of wild fruits. D. suzukii gathers on fruit that have dropped onto the ground and are spoiled or fermented. A preliminary report on Drosophila fauna of Islamabad (Capital, Pakistan).

Drosophila suzukii., Beers EH, Steenwyk RAVan, Shearer PW, Coates WW, Grant JA, 2011. Spotted-wing drosophila (SWD; Drosophila suzukii; Family: Drosophilidae) is a key pest that targets a wide variety of susceptible fruits including tree stone fruits (e.g., cherries) and berries (e.g., strawberries, blueberries, raspberries and blackberries). In: The Alachua Grower, Radonjić S, Hrnčić S, 2015. D. subpulchrella Takamori and Watabe males’ black spots are very similar in shape and position to those of D. suzukii (Takamori et al., 2006). As part of this role, Australia has responded to the incursion of a new pest, spotted-wing drosophila (Drosophila suzukii), in North America where it was confirmed attacking a range of fresh fruits in 2009. Final pest risk analysis report for Drosophila suzukii. Unlike most other vinegar flies that require damaged fruit to attack, SWD causes damage when the female flies cut a slit and lay eggs in healthy fruit. Terra Trentina, 55(10):19-23, Gueguen G, Rajwani R, Paddibhatla I, Morales J, Govind S, 2011. A variety of trap prototypes made by researchers and commercial traps are available to monitor adult D. suzukii. Approx. Contact for free printed copies. Adults often feed on fruits that has been split or damaged by birds. The fly called spotted wing drosophila (SWD, Drosophila suzukii) is emerging as a global plant pest of significance. On the basis of the shape and length of the ovipositor, D. suzukii can be easily discriminated from related species, such as D. biarmipes, but not easily from other species such as D. immigrans Sturtevant and D. subpulchrella (Takamori et al., 2006), which possess very similar ovipositors (Hauser, 2011). The species was later described in 1931 by Dr Shounen Matsumura as Drosophila suzukii Matsumura, and he gave it the common name of cherry drosophila (Kanzawa, 1935). In June, 1916, maggots were found to be infesting pre-harvest cherries (Prunus avium) in Yamacho, Higashi Yamanashi County, Yamanashi Prefecture, Japan (Kanzawa, 1935). The species is endemic in Asia. D. suzukii produces up to five times more hemocytes than D. melanogaster, making it significantly more resistant to wasp parasitism (Kacsoh and Schlenke, 2012) and making it less likely for indigenous specialized parasitoids to shift host onto it. Ecological, morphological and molecular studies on Ganaspis individuals (Hymenoptera: Figitidae) attacking Drosophila suzukii (Diptera: Drosophilidae). Host susceptibility of 'French Prune' Prunus domestica to Drosophila suzukii (Diptera: Drosophilidae). Later, it was confirmed present in Europe where it was also attacking a range of fresh fruits. This lure has been lately improved by adding wine (Landolt et al., 2012 ) and wine and sugar (Grassi and Maistri, 2013).

In 2008 economic losses (based on maximum reported yield losses) for California, Oregon and Washington were estimated at 40% for blueberries, 50% for caneberries, 33% for cherries and 20% for strawberries. D. suzukii may also be introduced to new areas via the transport of flowers, although this is less likely. Chemical control programs for Drosophila suzukii that comply with international limitations on pesticide residues for exported sweet cherries.
