David Handley, Vegetable and Small Fruit Specialist; James Dill, Pest Management Specialist; Frank Drummond, Professor of Insect Ecology/Entomology. Trap counts of spotted wing drosophila rose dramatically in some locations over the past week. We are now finding fly numbers in the thousands at more than half of our trapping sites. (See table below.) All sites remain well over the threshold for larvae infestation if susceptible crops are not protected with regular sprays or netting. A spray interval of every 5 to 7 days should be adequate to prevent any marketable fruit remaining in the field from becoming infested. Continue harvest regularly and often, and keep overripe and rotten fruit out of the field as much as possible. Long range weather forecasts suggest continued warmer than normal temperatures ahead, which will both extend the late berry season and likely keep spotted wing drosophila pressure high.. ...

Monitoring for Spotted Wing Drosophila (SWD) in fruit crops in east Michigan throughout the fall has detected this pest in six additional counties in the last two months. It was detected in one additional county earlier in September and in another east Michigan county last fall.. As of yesterday (November 17), USDA-APHIS confirmed that insects caught in the last few weeks in traps in Lapeer, Macomb and Wayne counties were indeed SWD. Two weeks ago they confirmed SWD in Livingston County, the week before that in Oakland County, and the week before that in Monroe County. Most of these trap catches were at fruit farms.. On September 20, the USDA-APHIS confirmed a SWD catch from a fall red raspberry field in Washtenaw County (see "Spotted wing Drosophila fly activity is increasing - be prepared in fall raspberries"). The September 2010 SWD catch was in Genesee County.. The total now stands at eight counties in east Michigan where we have caught SWD. Across the state, there is now a total of 22 ...
The Spotted Wing Drosophila is an invasive fly that poses a threat to soft-skinned fruit crops, such as berries and cherries. Since first detection in the United States in 2008, it has rapidly spread to become a pest across the country, with a huge impact on the production of susceptible crops. More information about the flys biology can be found on our Spotted Wing Biology Page.. ...
The spotted wing Drosophila (SWD), Drosophila suzukii (Matsumura) is a pest of soft fruit native to Asia, but was found in California starting in 2008, and in Washington and Oregon in 2009. Most Drosophila species, collectively known as vinegar flies, are attracted to overripe and rotting fruit for ovipositing sites, but SWD females have saw-like ovipositors which they use to lay eggs in ripening fruit, still on the plant. Fruits targeted by this pest include strawberry, raspberry, blueberry, plum, peach, cherry, and grape. Damage is seen initially as tiny scar on the skin of the fruit, and then the skin collapses and may become moldy in the area where the egg was laid and the larva is developing. The larvae will feed inside the fruit for 5-7 days. Adult females can lay up to 350 eggs in a lifetime. A research team, including scientists from California, Oregon, Washington and British Columbia are collaborating to understand the lifecycle of this pest as well as monitoring and management ...
CORVALLIS, Ore. - A newly recognized pest in Oregon continues to concern fruit growers and researchers with the recent discovery of a Spotted Wing Drosophila fly in a sample of Willamette Valley wine grapes.. Since the tiny fly, Drosophila suzukii, was first confirmed in Oregon less than two months ago, there have been an increasing number of reports of its occurrence in a variety of fresh fruits, including blueberries, peaches, raspberries, strawberries, blackberries, plums - and now grapes, according to Amy Dreves, a research entomologist at Oregon State University.. "This is an insect that, up to last year, had never been seen in the continental United States," Dreves said. "Now, suddenly, it is showing up in lots of places.". Losses to fruit crops have been significant in some places this year, according to OSU entomologist Vaughn Walton, who is working with Dreves and others on strategies to combat this invasive fruit fly. California lost about one-third of its cherry crop from Davis to ...
Most drosophila flies feed on damaged over-ripe fruit. Spotted wing drosophila (SWD) is a serious pest because it attacks healthy ripening fruit as well as damaged or split fruit.. Female SWD prefer to lay eggs in ripe fruit (Figure 1) but will also lay eggs in unripe, overripe and damaged fruit.. The female SWD penetrates the skin of soft-skinned fruit with a large serrated ovipositior. Eggs are laid just under the skin of the fruit creating a small puncture or sting on the fruit surface.. Affected fruit does not show obvious symptoms of infestation until the flesh starts to break down leading to discolouration. White larvae are noticeable in the rotting flesh (Figure 2). ...
November 9, 2018. Growers, agronomists, extension professionals and international researchers gathered at a recent series of workshops to improve preparedness for a high priority exotic fly pest, spotted wing drosophila.. Plant Health Australia, CESAR and Plant & Food Research New Zealand are working together on a Hort Innovation funded project to improve the preparedness of horticultural industries for the exotic fly.. The project has two main goals. The first is to increase the chance that the exotic pest would be promptly detected and reported by increasing both awareness and knowledge of the pest. The second is to improve Australias capacity to respond to an incursion of the fly.. The first awareness and education activities, a series of workshops, were run between 30 October and 2 November.. International researchers Professor Rufus Isaacs from Michigan State University, USA, and Benthan Shaw from East Malling Research, UK, shared their knowledge about identifying and managing the ...

Detecting larval infestations and insecticidal options for Spotted Wing Drosophila, a significant pest of small fruit crops in Missouri
Exirel has recently received minor use label expansion (URMULE) registration for control of aphids and the suppression of thrips in strawberries and the control of black vine weevil, obscure root weevil, spotted wing drosophila and Japanese beetle in caneberries in Canada. Exirel was already labeled for use on a number of crops in Canada for control of various insect pests including black vine weevil adults and clay coloured weevil adults in bushberries (CG 13-07B).. For optimum control of spotted wing drosophila, black vine weevil and obscure root weevil, tank mix DuPont Exirel insecticide with Hasten NT spray. adjuvant at an application rate of 0.25% v/v.. For optimum control of aphids and thrips apply Hasten NT spray adjuvant at an application rate of 0.25% v/v or MSO Concentrate with Leci-Tech at an application rate of 0.5% v/v.. It is recommended that a small area be tested to demonstrate safety to fruit and leaves before using in large areas.. For spotted wing drosophila, begin ...
The most enriched categories (function or protein domains) representing gene families that are specifically expanded in D. suzukii (and most likely in D. biarmipes and D. takahashii), i.e., significantly enriched in all three comparisons, include "glycerol metabolic process," "regulation of cellular protein metabolic processes," and "zinc finger proteins" (Table 2). Other notable functional annotations that are enriched in gene families expanded in D. suzukii, especially when compared to more basal Drosophila species, include "detection of stimulus," "sensory transduction," "G-protein-coupled receptor protein signaling," "proton-transporting ATP synthase activity," and "endopeptidase inhibitor." These categories are not significantly enriched in expanded D. suzukii gene families as compared to species in the melanogaster subgroup, suggesting that expansion of these gene families predates the divergence of D. suzukii and the melanogaster subgroup. Future functional characterization will be ...
The invasive species of Drosophila suzukii, the spotted wing drosophila of the Drosophilidae family is an invasive polyphagous species. In this research the dynamics of the population of D. suzukii was followed in three orchards in Zagreb (Maksimir, Jelenovac, Zelenjak) in the period from March 20 to November 27 2017. Feeding traps with apple vinegar were used for catching D. suzukii. The flight began in the period from 27 June to 11 July and lasted until November 27. The total number of catches was 874; in Jelenovac 187, in Maksimir 232 and in Zelenjak 455. From September to November there was a continuous flight and a large increase in the number of caught flies, from which presume the presence of more overlapping generations. Beside the host plants, the development of the pest in this area is also enabled by suitable climatic conditions. The present population in the city of Zagreb poses a danger to fruit producers in the vicinity of Zagreb. The results of this research are a contribution to ...
BERN, SWITZERLAND - Swiss federal agriculture officials say that the cost of fighting the devastating Drosophila suzukii (spotted wing drosophila) pest could start at CHF3,000 per hectare, and rise, depending on the intensity of the growers efforts to deal with it. One hectare can provide a wine producer with anywhere from 700 to 3,000 bottles […] ...
Type 2 diabetes affects over 300 million people, causing severe complications and premature death, yet the underlying molecular mechanisms are largely unknown. Pancreatic islet dysfunction is central in type 2 diabetes pathogenesis, and understanding islet genome regulation could therefore provide valuable mechanistic insights. We have now mapped and examined the function of human islet cis-regulatory networks. We identify genomic sequences that are targeted by islet transcription factors to drive islet-specific gene activity and show that most such sequences reside in clusters of enhancers that form physical three-dimensional chromatin domains. We find that sequence variants associated with type 2 diabetes and fasting glycemia are enriched in these clustered islet enhancers and identify trait-associated variants that disrupt DNA binding and islet enhancer activity. Our studies illustrate how islet transcription factors interact functionally with the epigenome and provide systematic evidence that the
Winter severity and overwintering capacity are key ecological factors in successful invasions, especially in ectotherms. The integration of physiological approaches into the study of invasion processes is emerg- ing and promising. Physiological information describes the mechanisms underlying observed survival and reproductive capacities, and it can be used to predict an organisms response to environmental per- turbations such as cold temperatures. We investigated the effects of various cold treatments on life his- tory and physiological traits of an invasive pest species, Drosophila suzukii, such as survival, fertility and oxidative balance. This species, a native of temperate Asian areas, is known to survive where cold tem- peratures are particularly harsh and has been recently introduced into Europe and North America. We found that cold treatments had a strong impact on adult survival but no effect on females fertility. Although only minor changes were observed after cold treatment on studied

PY - 2019/7. Y1 - 2019/7. N2 - Spotted-wing drosophila, Drosophila suzukii (Matsumura), is an invasive pest affecting fruit production in many regions of the world. Insecticides are the primary tactic for controlling D. suzukii in organic as well as conventional production systems. Organic growers have a greater challenge because fewer insecticides are approved for use in organic agriculture. The most effective organically approved product is spinosad, but alternatives are needed because of label restrictions limiting the number of applications per year, toxicity to beneficial arthropods and the risk of ...
There is a large number of biological databases that have become available in the public domain in recent years. According to the latest NAR database edition, there are more than 1600 listed database [1]. This is an under representation of the total number as there are many commercial and private databases. The number and size of private databases are in the rise [2, 3] mainly due to high throughput technologies being used in biological research. These biological databases can be in standard formats like flat files, VCF, XLS, GFF, BED etc [4, 5]. or other user defined formats. Furthermore, some databases are only accessible through an API or via a website (e.g. genecards.org).. Searches on these databases can be categorized as exact searches and exploratory searches. In exact searches user has the complete idea of what he is searching for while in exploratory searches, user only has a vague idea about what he is searching for. An example for the former type of search is a search for information ...

SPOTTED WING DROSOPHILA. The spotted wing drosophila (SWD) has been found in Maine this week, and was found in southern New England a week or two ago. Only a few flies have been caught in traps set up to monitor the pest. It is in such low numbers that it is not a concern to fruit ripening now. But this pest has a proven record of explosive growth, and growers of soft fruits that ripen in August must be aware of the issue and make management decisions.. This fruit fly is a new pest in our region. It is a common pest in parts of Asia. The tiny fly looks like a typical fruit fly, but the males have a spot on each wing that you can barely see with the naked eye. Common fruit flies that we see here only go after over ripe and rotting fruit. The SWD is a much greater problem because it can attack sound fruit and has been very damaging to raspberries, blueberries and other late summer soft fruit. Two years ago was the first year it was seen in large numbers in northern New England. Last year on my ...
You can do the math. Lets think optimum conditions for SWD development. A single female can lay around 350 eggs during her lifetime, about 15 per day. The egg to adult phase of the life cycle takes as little as 6 days. So, one female in one day can result in 15 more adults 6 days later, and, during those 6 days, she will have laid another 90 eggs. 6 days after that, those 90 eggs will all be adults. Half of the 105 adults will be females, capable of laying ~350 eggs during their lifetimes...thats 18,375 eggs. A typical life span for SWD is 3 to 9 weeks and there are estimated to be about 10 generations per year in the US, depending on climate.. ...
For home-owners. The insecticide Spinosad (e.g., Monterey Garden Insect Spray) is effective and has the least negative environmental effects of currently available products. Some spinosad products are sold to be applied with a hose-end sprayer, but a compressed-air sprayer will give more reliable coverage. Fertilome® Borer, Bagworm, Tent caterpillar and Leafminer spray (spinosad 0.5%) and Green Light® (spinosad 0.5%) are also labeled for use in bushberries and caneberries against fruit flies. The organophosphate insecticide malathion is widely available and will also control SWD, but malathion is very toxic to bees and natural enemies of other pests in the garden so care must be taken to keep the application on the target plant and avoid drift and runoff. Improper application also can result in injury to cherry trees. Because of the potential negative impact of malathion in the garden, use it only where you are certain you will have a SWD infestation, either because you had a problem last year ...

Deciphering invasion routes from molecular data is crucial to understanding biological invasions, including identifying bottlenecks in population size and admixture among distinct populations. Here, we unravel the invasion routes of the invasive pest Drosophila suzukii using a multi-locus microsatellite dataset (25 loci on 23 worldwide sampling locations). To do this, we use approximate Bayesian computation (ABC), which has improved the reconstruction of invasion routes, but can be computationally expensive. We use our study to illustrate the use of a new, more efficient, ABC method, ABC random forest (ABC-RF) and compare it to a standard ABC method (ABC-LDA). We find that Japan emerges as the most probable source of the earliest recorded invasion into Hawaii. Southeast China and Hawaii together are the most probable sources of populations in western North America, which then in turn served as sources for those in eastern North America. European populations are genetically more homogeneous than North

MINNEAPOLIS (AP) - An invasive fruit fly from Asia is upending the economics and growing techniques for raspberries, blueberries and grapes in Minnesota.. The Star Tribune reports that spotted wing drosophila damage crops, shorten harvesting seasons, increase insecticide use and reduce income for producers. They were first detected in the state in 2012.. The flies lay eggs in ripening fruit. The eggs grow into small white worms that turn fruit into mush.. Fall raspberries are the most vulnerable fruit, but the bugs also invade blueberries, blackberries, summer strawberries and grapes that have soft skins.. University of Minnesota Extension entomologist Bill Hutchison estimates that 20 to 25 percent of berry growers in the state have suspended production or gone out of business because of the bugs.. ...

Cancer is driven by genetic change, and the advent of massively parallel sequencing has enabled systematic documentation of this variation at the whole-genome scale1-3. Here we report the integrative analysis of 2,658 whole-cancer genomes and their matching normal tissues across 38 tumour types from the Pan-Cancer Analysis of Whole Genomes (PCAWG) Consortium of the International Cancer Genome Consortium (ICGC) and The Cancer Genome Atlas (TCGA). We describe the generation of the PCAWG resource, facilitated by international data sharing using compute clouds. On average, cancer genomes contained 4-5 driver mutations when combining coding and non-coding genomic elements; however, in around 5% of cases no drivers were identified, suggesting that cancer driver discovery is not yet complete. Chromothripsis, in which many clustered structural variants arise in a single catastrophic event, is frequently an early event in tumour evolution; in acral melanoma, for example, these events precede most somatic point
Epigenetic dysregulation is recognized as a hallmark of cancer. In the last 16 years, a CpG island methylator phenotype (CIMP) has been documented in tumors originating from different tissues. However, a looming question in the field is whether or not CIMP is a pan-cancer phenomenon or a tissue-specific event. Here, we give a synopsis of the history of CIMP and describe the pattern of DNA methylation that defines the CIMP phenotype in different cancer types. We highlight new conceptual approaches of classifying tumors based on CIMP in a cancer type-agnostic way that reveal the presence of distinct CIMP tumors in a multitude of The Cancer Genome Atlas (TCGA) datasets, suggesting that this phenotype may transcend tissue-type specificity. Lastly, we show evidence supporting the clinical relevance of CIMP-positive tumors and suggest that a common CIMP etiology may define new mechanistic targets in cancer treatment.
