It seems like such a horrific pest. Another option is to select varieties of fruit that have thicker skins, since the flies take longer to lay eggs in these types of fruit. You should check for infestation between sprays to determine if the treatments are working. Some control treatments of the cherry fly can also help in the control of the Drosophila Suzukii. DuPont ™ Exirel® based on the Cyazypyr® insecticide is one of the authorized products during the 2017 cherry campaign.

Spotted-wing drosophila, Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) is a pest of small fruits and cherries. The only natural enemy that did have an effect on the development of the Drosophila population was the parasitic wasp. The fly Drosophila suzukii  (Matsumura, 1931) is a plague of Asian origin with high virulence and rapid expansion capacity. The content of the bottle is poured into the ECONEX BOTTLE TRAP DS, which –after that– must be hanged in an appropriate place, in order to capture Drosophila suzukii. Reducing the survival of the SWD can lower the chances that your fruit will become infested. See our TOS for more details. Effective but forbidden at the moment to present residues in the cherry when it is applied in period of maturity. This makes sense, since the flies are attracted to red fruit like cherries and raspberries. Commercial lures typically last at least four weeks. Make sure that the holes in the trap are not blocked with vegetation, so that the SWD can easily fly in. The need to apply treatments for the control of Drisophila Suzukii increases the production costs of the cherry, strawberry….

If you do find larvae, it’s possible that they are from some other kind of insect. Fruits like cherries will show visible dents around the larvae. Researchers at Cornell University, including Laura McDermott and colleagues, tested a number of insecticides that homeowners can buy that are labeled for use against these pernicious flies. Navigate through the online version by selecting the chapter of interest from the drop-down list at top left. Although it has also been detected in fruits such as kaki, plum or kiwi. Therefore D. suzukii poses a serious threat to many soft fruits and orchard crops with economical losses from 5 % up to 100 %. (Photo by Sean McCann, Ph.D.) My guess is that it’s not feasible to treat such large areas of soil. Conventional and organic spray programs in blueberry provide control of D. suzukii. You can find an extensive list of the wild hosts of the SWD in southern New England at the website of the Cornell University Fruit Resources page for the insect. Unlike most other Drosophila species D. suzukii oviposits and feeds on healthy fruits [6]. Nothing works like a sticker that says, “Put me in the refrigerator.”. 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. What about Pyrethrin based sprays? Overview Origin Drosophila suzukii is an invasive and economically important pest of many soft-skinned fruits such as blueberries, blackberries, raspberries, strawberries, cherries, and other fruits. Picking cherries on time before they overmatter is also a good form of control. An added benefit from the plastic barrier is that it helps to manage weeds and retain water. However, the adult males differ from other native Drosophila males in that they possess a dark spot along the This feeding makes the fruit vulnerable to additional damage from other insects or from molds. One of them, the melanogaster species group, also contains the famous “workhorse” of experimental biology and genetics, Drosophila melanogaster Meigen. One of them, the melanogaster species group, also contains the famous “workhorse” of experimental biology and genetics, Drosophila melanogaster Meigen. About Spotted Wing Drosophila and the SCRI SWD Project. Several major universities had long focused on organic control methods for the SWD. The insect resembles common vinegar flies in the genus Drosophila. Given its potential to infest fruit, it is important to learn about monitoring and management of SWD to minimize th… 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. You can gently squeeze fruit like blueberries. An example is a blueberry grower in southern Minnesota. If you cool the fruit for three days, it will kill the SWD. One is for marketable fruit. Two sanitizers used in tank mixes or rotations with insecticides show promise for use in organic programs. Mixtures of yeast, sugar, and water; fruit purees, distillates from apple cider vinegar or wine; ethanol, acetic acid, and phenylethanol in 1: 22: 5 ratios ar… Cull the fruit that are infected and remove them ASAP. The spotted wing drosophila (SWD), Drosophila suzukii (Matsumura), is an invasive vinegar fly with a preference for infesting commercially viable berries and stone fruits. Use a 10-30X magnifying glass to look for the serrated ovipositor of the SWD females.

If you identify the dreaded pest on your property, it is time to take action. Although they are registered as fungicides and not insecticides, Jet-Ag®and OxiDate®2.0 can improve the action of insecticides that are only rated as providing a “fair” level of control of the SWD. 4. Adult females of Drosophila Suzukii damage the surface of the cherry during laying. The suzuki-fruit fly Drosophila suzukii, a new pest of fruit in the Netherlands. If you use high tunnels in a warm climate, you may need to use ventilation to prevent your plants from being damaged by overheating. Agriculture to monitor and control the spread of the fly.

It is a major threat to Spanish an… The male SWD looks like a typical fruit fly except that it has a noticeable black spot on the front edge of its wing. Introduction 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]. Helsen H, Bruchem Jvan, Potting R, 2013. It differs from other species of drosophilas by having a sawed oviscapto (organ used for laying eggs) that allows it to attack healthy fruits. Drosophila suzukii remains a serious threat to the UK soft fruit industry. Management practices for spotted-wing drosophila are similar to those used to manage common Drosophila flies. Under optimal conditions this fly can reach up to 15 generations per year. Many natural enemies have been tested – including Hemiptera (such as aphids, heteroptera and cicadas), beetles and mites – in the control of the Drosophila suzukii. Here in NYS, would the larvae die in the ground over the winter? 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. An additional advantage of using netting is that it can also protect against birds, some other types of insects, and certain rodents. This species causes severe damage to healthy fruit in comparison to other fruit flies. You can tell the males by the distinctive dark dots on their wings. One way to do so is to randomly select 25 fruit from your garden and put them in a Ziploc bag. Drosophila suzukii, commonly called the spotted wing drosophila or SWD, is a fruit fly.

This pest causes damage to fruit in the immediate pre-harvest period, thus making insecticide application challenging. D. suzukii belongs to the subgenus Sophophora, which is divided into several groups of species. They are highly annoying but don’t do much harm. Significant progress has been made in understanding the cues involved in the host and mate seeking behaviors of spotted wing drosophila, Drosophila suzukii (Matsumura). She transitioned to full-time writing in 2009. Pacific Northwest Insect Management Handbook-- This handbook is updated annually and provides control recommendations for a wide range of agricultural pests.
