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]. Although the spotted-wing drosophila Drosophila suzukii originates in Southeast Asia, this pest is now widespread in North America, Central America and Europe. The model is used to explore optimal timing for releasing parasitoids in biological control programs. Identify wild and ornamental hosts of spotted wing Drosophila (SWD) that serve as population reservoirs for infesting crop fields. The sterile insect technique is a new approach for the integrated management of Drosophila suzukii Matsumura (Diptera: Drosophilidae), an invasive pest in North America. I CONTENT CONTENT I LIST OF ABBREVIATIONS III SUMMARY VI ZUSAMMENFASSUNG VIII CHAPTER I: GENERAL INTRODUCTION 1 DROSOPHILA SUZUKII: BIOLOGY, … Elle a été décrite pour la première fois en 1931 au Japon. The technical department of Koppert Spain recommends berry producers to immediately start installing traps for the biological control of the Drosophila suzukii fruit fly. Drosophila suzukii Matsumara, 1931. Seasonality of the environment is captured through a system of delay differential equations with variable delays. The Drosophila suzukii can be controlled with insecticides (Spinosad / Tracer) 4, but these – due to the risk of remaining residues on the grapes – cannot be used in the last moment of the ripening phase, or are toxic to beneficial insects such as bees. This species causes severe damage to healthy fruit in comparison to other fruit flies. It has been introduced into Europe and the Americas in the past decade, and is now firmly established in large parts of these continents [ 13 , 14 ]. Gabarra y col. (2015) Prospects for the biological control of Drosophila suzukii. Biological control of Drosophila suzukii: Efficacy of parasitoids, entomopathogenic fungi, nematodes and deterrents of oviposition in laboratory assays Unlike most other Drosophila species D. suzukii oviposits and feeds on healthy fruits [6]. Abstract. 1) (Lee et al. Spotted-wing drosophila, Drosophila suzukii (Matsumura), is an invasive pest affecting fruit production in many regions of the world. It has a wide host range and these non-crop habitats harbor the fly which then repeatedly reinvades crop fields. Biological control in non-crop habitats could be the cornerstone for sustainable management at the landscape level. The invasive pest Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) causes serious economic damage in several soft fruit crops. Parasitoids from the families Braconidae and Cynipidae are potential biocontrol agents of Drosophila suzukii. Many features are typical for Drosophila fruit flies, with a few key differences.Male and female characteristics are key identifiers for this species. The global fresh fruit trade, coupled with the ability of the larvae to hide inside the fruit undetected until after transportation, facilitate their distribution. Drosophila suzukii, commonly called the spotted wing drosophila or SWD, is a fruit fly.D. To date, there have been no reports of widespread damage. 2011a; Calabria et al. Main content area.

Orius insidiosus has been reported to feed exclusively on Drosophila suzukii. Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), the spotted wing drosophila (SWD), is the most important pest affecting berry crop production worldwide. Drosophila suzukii (Matsumura) is native to East Asia but has widely established in the Americas and Europe, where it is a devastating pest of soft-skinned fruits. The spotted wing drosophila fly, Drosophila suzukii (Matsumura, 1931) (Diptera: Drosophilidae), is a pest which caused serious crop losses to soft-skinned fruits such as cherries, strawberries, and grapes. This species, whose development is very dependent on temperature and high relative humidity, can attack a very wide range of cultivated and wild fruits. BioControl (DOI: 10.1007/s10526-014-9646-z) Rossi Stacconi y col. (2013) First field records of Pachycrepoideus vindemiae as a parasitoid of Drosophila suzukii in European and Oregon small fruit production areas. Identification, Biology, and Life Cycle. Note: only the male flies have spots on their wings. Current control programs rely solely on the use of frequent insecticide applications. In this study, population dynamics of D. suzukii and its associated parasitoids were investigated. Host specificity tests were conducted with three Asian and one European parasitoid species, using five European Drosophila spp. Drosophila suzukii populations remain low in the UK. Biological control. with semiochemicals, and biological control using imported native parasitoids are likely to be crucial for future sustainable integrated management. (Kanzawa 1939, Dubuffett et al. Finally, the wealth of genetic information accumulated in D. melanoagster is being exploited to find alternative genetic-based control strategies. Entomologia 1e3:11-16 Drosophila suzukii is an invasive plague native to Southeast Asia that has colonized several countries in America and most European countries. The development of biological control methods for exotic invasive pest species has become more challenging during the last decade. NWO Biological control of the new invasive pest species Spotted Wing Drosophila. Adults: 2-3 mm (1/8 inch) long, brownish with red eyes and clear fly-like wings.Compared to other fruit flies, D. suzukii is a robust fly, but this is difficult to discern unless compared directly to other species. How is D. suzukii related to the other Drosophila? The Spotted Wing Drosophila (SWD), Drosophila suzukii, is an invasive fruit fly from Asia that infests ripening fruit. Previous research demonstrated that various species of entomopathogenic fungi and nematodes could potentially suppress D. suzukii population development under laboratory trials. ... CONTROL Chemical. The soft-fruit pest Drosophila suzukii, or spotted-wing drosophila (SWD), is particularly difficult to control because of its short generation time and its very broad host range, including many wild and ornamental plants.The pest has been causing damage to fruit crop in Europe as well as North America where damages costing $500million were reported in the USA. Spotted wing drosophila, Drosophila suzukii Matsumura (Diptera: Drosophilidae), is a major pest of bushberries, caneberries, and other thinskinned fruits around the world. Test the effectiveness of predators for biological control of SWD. Introduction Spotted wing Drosophila, Drosophila suzukii (Matsumura) or SWD, is a newly significant worldwide pest of berries and stone fruits, with adverse economic effects having been reported in its native continent of Asia, the Americas, and Europe (Fig. 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. Martin Cooper via CC BY 2.0. Item Type: Ph.D. Thesis: Title: 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. Biological control with parasitoid wasps is currently being discussed for the spotted wing Drosophila, Drosophila suzukii (Matsumura; Diptera: Drosophilidae), an invasive species native to Asia. 3. Compared to indigenous ... illustrate this approach with a case study on parasitoids of Drosophila suzukii, a highly invasive pest species in … and one Tephritidae species as hosts. However, none of the given species was concluded to be specifically efficient in suppressing D. suzukii. This special issue will deal with importation biological control against invasive exotic pests and weeds around the world, covering the current situation with selected reviews and case studies, and will explore some of the challenges and potential solutions. Drosophila suzukii, aussi appellée "drosophile du cerisier", est une mouche originaired'Asie du Sud-Est. Appearance. Drosophila suzukii is a serious pest of soft fruit crops worldwide and classical biological control may provide an alternative to the use of chemical insecticides. The development of biological control methods for exotic invasive pest species has become more challenging during the last decade. 2009, Walsh et al. 2011). Ses fortes capacités d'adaptation et de dispersion géographique lui ont permis d'infester progressivement les continents asiatique, américain et européen. It is rapidly spreading north in Europe and already causes millions of euros of damage in the fruit industry. Drosophila suzukii females possess a suzukii, originally from southeast Asia, is becoming a major pest species in America and Europe, because it infests fruit early during the ripening stage, in contrast with other Drosophila … Spotted-wing drosophila. Therefore D. suzukii poses a serious threat to many soft fruits and orchard crops with economical losses from 5 % up to 100 %. Drosophila Suzukii female with magnified ovipositor. 2. The spotted wing Drosophila (Drosophila suzukii) is from East Asia and then became established in Hawaii.These fruit flies are about 1/10-inch-long and have bright red eyes and black horizontal stripes on their abdomens. Test the effectiveness of entomopathogenic nematodes for biological control of SWD. biological control agents. This study aimed (1) to identify naturally occurring parasitoids and predators of this pest in North East Spain and (2) to get preliminary data on their potential as pest biological control agents. Biological control is the use of beneficial insects to manage other insects, which means using less pesticides. We present a model for the population dynamics of the invasive fruit fly Drosophila suzukii and its pupal parasitoid Trichopria drosophilae. Drosophila suzukii has become a key invasive pest of soft- and thin-skinned fruit crops in its invaded regions in Europe and Americas, where naturally occurring natural enemies are generally not effective for the suppression of this pest or largely absent such as larval-attacking parasitoids. 2012; Request PDF | On Nov 12, 2013, Jana C.
