One of the first things you should do is check your fruit. This makes them a particular threat because the flies can migrate between different types of fruit as they ripen at different times, so many kinds of fruit can be infested during a single season. Evaluation of Natural Antagonists for Biological Control of Drosophila suzukii: Language: English: Abstract: The polyphagous insect Drosophila suzukii (eponymous: spotted wing drosophila, SWD) is indigenous to Southeast Asia and has been spreading rapidly in North American and European countries since 2008. Biganski, S., J. Wang, X. G., A. H. Nance, J. M. L. Jones, K. A. Hoelmer, and K. M. Daane. In conclusion, resident predators and parasitoids can suppress spotted-wing drosophila, and should be conserved in crop fields and adjacent wild habitat. You may have a mix of different types of fruit flies, and some native fruit flies superficially look like the SWD. Grapes are not a preferred host, but the SWD will infest them if they have damage from hail or birds or cracks in the fruit. israelensis at high doses did not cause significant mortality among spotted-wing drosophila larvae and adults, nor reduce their reproductive output (Biganski et al. Make a solution of saltwater using 1-2 teaspoons of salt per cup of water and put it in the bag. You should check for infestation between sprays to determine if the treatments are working. Keywords: Drosophila suzukii; control; pesticide OPEN ACCESS . They do better in more moderate climates. 2017), gene drives (Buchman et al. The female even has a special egg-laying organ that is serrated like a saw, so she can lay her eggs inside ripening fruit. Shaw, B., P. Brain, H. Wijnen, and M. T. Fountain. Biotic and abiotic factors impacting development, behavior, phenology, and reproductive biology of Drosophila suzukii. Bruck, D. J., M. Bolda, L. Tanigoshi, J. Klick, J. Kleiber, J. DeFrancesco, B. Gerdeman, and H. Spitler. There are multiple parasitoid species that target larvae and pupae, including non-native species being evaluated for potential release. The invasive fruit fly spotted wing drosophila (Drosophila suzukii) originated in Asia but has invaded regions around the globe.A new review of existing research published in May in the Journal of Insect Science details the species’ high degree of phenotypic plasticity—the ability to shift traits in response to environmental influences. 2017). Rossi Stacconi, M. V., N. Amiresmaeili, A. Biondi, C. Carli, S. Caruso, M. L. Dindo, S. Francati, A. Gottardello, A. Grassi, D. Lupi, et al. With great care, you can avoid being one of the growers who loses their late season crop to the ravages of this pest. First, not all adult flies will come into immediate contact with the product. In a closed lab environment these had a limited effect, but this effect was no longer observable in the field5. By mulching with a black plastic weed barrier, you can interrupt this cycle. She holds a BS in agriculture from Cornell University, and an MS from the University of Massachusetts Amherst. Studies with sentinel pupae likely overestimate predation but nonetheless show high activity among ground predators. Mitsui, H., K. Van Achterberg, G. Nordlander, and M. T. Kimura. Follett PA, Swedman A, Price DK (2014) Postharvest irradiation treatment for quarantine control of Drosophila suzukii (Diptera: Drosophilidae) in fresh commodities. 3) Great idea with the black plastic. Not only does excessive insecticide harm biological control agents that directly suppress D. suzukii, it can harm other beneficial arthropods that suppress previously unimportant pests such as scales and aphids. Drosophila suzukii Matsumura (Figure 1A) is one of the most serious pests of thin-skinned fruits including blueberry, raspberry, cherry, grape and strawberry [1–5]. Unlike most other Drosophila species D. suzukii oviposits and feeds on healthy fruits [6]. Raspberries are too fragile for this treatment, but infested fruit may leave a red juice stain on the berry receptacle when you have picked the fruit. This strategy is especially important for organic fruit production. Ceden, C. J., D. A. Rutz, J. G. Scott, and S. J. When these parasitoids were screened with other Drosophila species, A. japonica was considered a generalist, and L. j. japonica and certain strains of G. brasiliensis were specialized for spotted-wing drosophila and closely related Drosophila (Girod et al. Spotted wing drosophila pupating on the surface of a cherry. Spotted-wing drosophila is often controlled by insecticides, which has led to insecticide resistance (Gress and Zalom 2019) and raised concerns about environmental impacts. Moreover, D. melanogaster reduced spotted-wing drosophila presence in test cages, whereas the parasitoid P. vindemmiae did not, suggesting that competitive mechanisms can be more effective than expected (Dancau et al. Unlike most other Drosophila species D. suzukii oviposits and feeds on healthy fruits [6]. 2017). Chemical control. That’s very kind of you to say. Drosophila suzukii have a rapid expansion worldwide; occurrences were recorded in North America and Europe in 2008, and South America in 2013. Entomopathogens have the potential to be applied on the foliage and fruit like other pesticides, applied to the soil to target pupae and wandering larvae, or used in a lure-and-infect system such as an autoinoculation trap. Third, fruits that are already infested will get sprayed and the fate of the internal developing spotted-wing drosophila is of interest. Drosophila suzukii (Spotted Wing) Description SWD is a small fly (2 to 3 mm) with bright red eyes, a pale brown thorax, and an abdomen with black horizontal stripes. Viral infections, as determined by DNA tests, are clearly present among spotted-wing drosophila in the field. Also cut back on moisture as much as you can. A polyphagous pest, it infests a wide range of fruit crops, included grape, as … 2b). Field trials with bacterial pathogens are needed before recommendation. The fruit fly D. suzukii is a fruit crop pest and is a serious economic threat to soft summer fruit. 2008), and augmentation box trials for spotted-wing drosophila control warrant future testing. Augmentative releases with predators and parasitoids are still under development, may be suitable for non-crop or protected areas, and future work might consider the compatibility of parasitoid releases in areas with high natural predation. Wang, X. G., B. N. Hogg, E. Hougardy, A. H. Nance, and K. M. Daane. As each natural enemy is covered, we address the impact observed in the field (i.e., predation rate), efficacy of commercial products available, and other options that may be available in the future. Lab efficacy trials with the ground predator D. coriara varied showing no impact or up to 50% reduction of spotted-wing drosophila in raspberry fruit (Supp Appendix [online only]; Renkema et al. You can tell the males by the distinctive dark dots on their wings. You can take several steps to kill the larvae. This sustained suppression can improve area-wide management by reducing spotted-wing drosophila populations that attack various susceptible crops throughout the seasons. 2015). 2017). More studies are needed to determine whether viruses can be delivered and spread among spotted-wing drosophila in the field, and which viruses to target in different locations. Little. It doesn’t help that a single female can lay more than 300 eggs in her lifetime! Kenis, M., L. Tonina, R. Eschen, B. van der Sluis, M. Sancassani, N. Mori, T. Haye, and H. Helsen. Thus, growers may be interested in augmenting these rove beetles by rearing them on dog/fish food and placing ‘breeding boxes’ in crop areas. Spinosad showed the highest acute toxicity to these predators even when residues were 3 or 7 d old, and Sabadilla alkaloids had acute toxicity to minute pirate bugs. Carabid beetles, crickets, green lacewing larvae, and rove beetles are other likely predators. One concern about this approach is that it can exclude pollinators, so if you have summer-blooming raspberries within netting, you should stock bumblebees or other pollinators to make sure that your plants will get pollinated. Chen, C.-X. The SWD reproduce rapidly and can produce at least 15 generations a year. Selective insecticides should likewise be considered to minimize harm to parasitoids. Dara S. K., T. Mann, D. -W. Li, and B. Layton. Insecticides and rates used in small plot trials for control of Drosophila suzukii in 2012 and in program comparisons at commercial blueberry farms in 2011 and 2012. This puts them in even greater proximity to fruit that they can infest. Stockton, D., A. Wallingford, D. Rendon, P. Fanning, C. K. Green, L. Diepenbrock, E. Ballman, V. M. Walton, R. Isaacs, H. Leach, et al. 2015). 2017). In the past, experts recommended burying the fruit. Although it is a native species of Asia (China, Japan, Korea and Thailand), the world trade in fruits has helped its spread around the world.

Kenis, and T. Haye. The small fruit flies are familiar insects to many people, sometimes found abundantly indoors, where they feed on yeasts associated with overripe fruit or the sediment of beverage containers. Emiljanowicz, L. M., G. D. Ryan, A. Langille, and J. Newman. Long. Due to concerns about the development of resistance to insecticides, you will have to switch to a different type of organic insecticide after two applications. Yet, even organic farms with high spotted-wing drosophila pressure frequently use Organic Materials Review Institute (OMRI)-listed insecticides to minimize infestation risk. This will have the added benefit of improving the spray coverage. It is critical to remove the fruit with larvae, so they won’t emerge as adults and lay eggs! It is possible that you could have the larvae in your fruit before you detected any adults in the traps, so it is critical to monitor the fruit. This paper reports the first confirmed incidence of this berry fruit pest in Slovenia in early October 2010, infesting vines of fox grape (Vitis labrusca) cv. Subsequent lab exposure tests showed ~25% of spotted-wing drosophila adults die when exposed to sporulating house fly cadavers (Becher et al. Growers have expressed strong interest in biological control and other sustainable tactics to reduce reliance on insecticides. 2. Acetamiprid provided good control against the SWD on apple, pear, grapes, or strawberries. This lets her lay her eggs within the fruit. This insect is susceptible to environmental stressors, and its development can be manipulated by changing the temperature and humidity conditions on the soil and in crop canopies (Diepenbrock and Burrack 2016, Rendon and Walton 2019). Damos, P., L. A. Colomar, and C. Ioriatti. Drosophila suzukii Matsumura (Diptera: Drosophilidae), a fruit fly from East Asia, is now a serious economic pest of soft fruits and berries across Europe, the Americas and North Africa. RNA interference (RNAi) or double-stranded RNA (dsRNA)-mediated gene silencing is rapidly becoming a widely used functional genomics tool in insects and holds great potential for insect pest control. Gabarra, R., J. Riudavets, G. A. Rodriguez, J. Pujade-Villar, and J. Arno. This fly is a particular threat to raspberries and blackberries and can totally devastate a late season crop. If you have help harvesting your fruit, you can give your helpers two buckets. Another advantage of using a trap in this manner is that you can wait to treat your crops until you are sure you have the SWD on your property.

Pfab, F., M. V. R. Stacconi, G. Anfora, A. Grassi, V. Walton, and A. Pugliese. This approach is known as Phenology Management. Future studies may include genetic improvement by selecting biological traits among different populations for breeding to improve biological control (Kruitwagen et al. Dr. Kirkpatrick found the flies were much more strongly attracted to red sphere and red panel traps baited with Scentry lure (a specialized attractant for fruit flies). Naturally occurring predators are consuming and removing a substantial portion of spotted-wing drosophila in low-input fields. Here in NYS, would the larvae die in the ground over the winter? Here is more about what we do. I’ve seen at least one that also includes Neem Oil, but not Spinosad, so I’m wondering if I can alternate between these 2? Certain landscape features such as forest cover near crops have been associated with more parasitoids, although the number of P. vindemmiae was still low (Haro-Barchin et al. Spotted-wing drosophila adults collected from Japan, France, and United Kingdom contained viral-like DNA sequence of 18 novel viruses, and 18 other viruses found in other Drosophila (Medd et al.
