Item Are There Yield Benefits to Recruiting Wild Pollinators in a Strawberry Agroecosystem?(2018) Hecht, Nathan D.; Hoover, Emily; Rogers, MaryItem Biocompatibility of OMRI listed insecticides on green lacewing (Chrysoperla carnea) larval mortality: implications for greenhouse vegetable production(2023-03) Worth, Leah; Rogers, Mary; Reardon, AmandaItem Economic Impact of Spotted Wing Drosophila (Diptera: Drosophilidae) Yield Loss on Minnesota Raspberry Farms: A Grower Survey(Journal of Integrated Pest Management, 2019) DiGiacomo, Gigi; Hadrich, Joleen; Hutchison, William D.; Peterson, Hikaru; Rogers, MaryMinnesota was dubbed the ‘raspberry consumption capital of America’ in 2017 by wholesaler Driscoll’s, Inc. Local production of this high-demand fruit, however, is limited by the invasive pest, spotted wing Drosophila (Drosophila suzukii Matsumura, Diptera: Drosophilidae). Recent research to develop integrated pest management (IPM) programs for MN berry crops indicates that raspberry growers are particularly vulnerable to significant spotted wing Drosophila-related yield losses. Spotted wing Drosophila was detected in Minnesota in 2012 across 29 counties. This analysis explores the economic impact of raspberry yield losses associated with spotted wing Drosophila in Minnesota as part of a multifaceted research initiative. An electronic survey of 157 MN berry growers was conducted in November 2017. Eighty-two individual grower surveys were returned (52% response rate). The survey included questions about production acreage, marketing practices, spotted wing Drosophila-related yield losses and future production intentions. The results of the e-survey indicate that raspberry growers have borne the highest levels of infestation among MN fruit growers surveyed. Spotted wing Drosophila-related yield losses for raspberry growers ranged from 2 to 100% of planted acreage.The median yield loss for this group of growers was 20% in 2017. Applying the median yield loss to ex-ante production estimates, we conclude that MN growers lost approximately $2.36 million in raspberry sales during the 1 yr studied. Investing in spotted wing Drosophila control measures will help MN growers reduce some of these losses in the future.Item Episode 4 Spotted Wing Drosophila Part 1: Dr. Mary Rogers on Keeping Out SWD: What's Killing My Kale?(2018-06) Klodd, Annie; Hoidal, Natalie; Rogers, MaryThis month's episodes of "What's Killing My Kale?" focus on Spotted Wing Drosophila. This invasive vinegar fly, now widespread in Minnesota, is a major concern for small fruit growers as it lays its eggs directly in the flesh of many high value fruits. This series of podcasts provides growers with top recommendations on managing SWD from Mary Rogers, Assistant Professor of Horticulture, Jim Riddle, long-time organic fruit grower and owner of Blue Fruit Farm, and Bill Hutchison, UMN Extension Entomologist. Additional information on SWD can be found at https://www.fruitedge.umn.edu/swd.Item Episode 6 (Season 3) Organic Management of SWD: What's Killing My Kale?(2020-04-10) Klodd, Annie; Hoidal, Natalie; Rogers, MaryAnnie talked with Dr. Mary Rogers, an Assistant Professor studying organic food production systems in the Department of Horticulture. They discussed recent research findings from Dr. Rogers team, as well as other farms and researchers around the country, about the best ways to manage SWD organically.Item Impact of Chickens and Clover Cover-Cropping on Soil Fertility & ‘MN Midget’ Melon Plant Health at the Student Organic Farm(2019) Galley, Jace; Rogers, Mary; Tchida, Courtney
