Ragsdale, D. W., D. J. Voegtlin, and R. J. O’Neil. In agroecosystems, plant-pest interactions are at the basis of complex food webs, which can be affected by both biotic and abiotic factors. Insecticide use (i.e., percent of planted acres treated with insecticide) (top figure) and crop scouting for insects and mites (i.e., percent of planted acres scouted) (bottom figure) in soybean in the Midwestern Region of the United States. They lay an egg inside an aphid, where the larvae eat the aphid â¦ It can be used It readily decomposes when exposed to sunlight. 2015), could further increase the use of scouting-based decision making for soybean aphid management. The LC50 values across all nine populations ranged from 0.6 to 24.57mg a.i./L. A sublethal concentration of beta-cypermethrin (LC5 for A.Â glycines) stimulated the reproduction of A.Â glycines but it did not impact the fecundity of A.Â solani. Bahlai, C. A., Y. Xue, C. M. McCreary, A. W. Schaafsma, and R. H. Hallett. In the United States, Chandrasena et al. If pyrethroid-resistance is suspected in an aphid population, products containing insecticides other than pyrethroids should be considered. Harlequin bugs, stink bugs, flea beetles and â¦ Similarily, a higher percentage of soybean acres has been scouted for arthropod pests in Minnesota, Iowa, and North Dakota than in other states in the region (Fig. Integration of multiple preventative and therapeutic tactics (Pedigo and Rice 2009) for soybean aphid management will increase the sustainability of soybean production in the Upper Midwest. 3). Aphids are tiny pear-shaped, soft-bodied insects that suck the juices out of leaves, stems and tender plantsâ though some species attack lettuce roots and the woody parts of apple tree roots and limbs. Mites may increase after some insecticides (esfenvalerate, permethrin, zeta-cypermethrin) are applied for control of other pests. Cypermethrin is a synthetic pyrethroid insecticide. Ribeiro, M. G. P.

Alves, and R. L. Koch. Zhu, Y.C., J. Adamczyk, T. Rinderer, J. Yao, R. Danka, R. Luttrell, and J. Gore. Pyrethroid-containing mixtures may provide adequate control of some pyrethroid-resistant populations of soybean aphid (IRAC 2012, R.L.K. Publication E1878, Assessing the value and pest management window provided by neonicotinoid seed treatments for management of soybean aphid (, Pyrethroid resistance in insects: genes, mechanisms, and regulation, Insecticides: advances in integrated pest management, Soybean aphid-resistant soybean varieties for Iowa. Economically significant infestation of soybean by this phloem-feeding insect can reduce soybean yield by up to 40% (Ragsdale et al. The continued validity of the 250-aphid-per-plant threshold is explained by Koch et al. Laboratory bioassays performed in 2017 confirmed resistance to pyrethroids in soybean aphid from the aforementioned states and Manitoba, Canada (R.L.K., unpublished data). Ragsdale, D. W., D. A. Landis, J. Brodeur, G. E. Heimpel, and N. Desneux. 2018) have created an immediate challenge for effective soybean pest management and profitable soybean production. Soybean aphid also can affect soybean through transmission of viruses (e.g., Soybean mosaic virus and Alfalfa mosaic virus) (Hill et al. It should also be noted that soybean fields planted with neonicotinoid-treated seeds have already received an application of a Group 4 insecticide (i.e., neonicotinoids). Due to the mobility of winged soybean aphids (Schmidt et al. 2015). 2012, Varenhorst and O’Neal 2012), and sulfoxaflor (Group 4C) (Tran et al. Improvements in the efficiency of soybean aphid scouting, such as the potential for remote sensing (Alves et al. 2007). Bahlai, C. A., W. van der Werf, M. O’Neal, L. Hemerik, and D. A. Landis. This work was supported in part by the Minnesota Soybean Research and Promotion Council, Iowa Soybean Association, North Dakota Soybean Council, and South Dakota Soybean Research and Promotion Council. Published by Oxford University Press on behalf of Entomological Society of America. In fields where pyrethroids failed to control soybean aphid, surviving (i.e., suspected resistant) aphids have sometimes been observed in patches within the field, which may be due to a mixture of aphid genotypes (e.g., Orantes et al. Ants ward off natural aphid enemies, so ant control is an important aspect of aphid control. 2016). In the present study, we evaluated the impact of the insecticide beta-cypermethrin on interspecific interactions between the specialist aphid Aphis glycines and the generalist aphid Aulacorthum solani on soybean. 2010, Frewin et al.

These findings hinted that the pyrethroid insecticide beta-cypermethrin has the potential to mediate the interspecific competition between specialist and generalist aphids (at the sublethal â¦ Oxford University Press is a department of the University of Oxford. Insecticide use on soybean in North America has increased dramatically in response to this pest (Ragsdale et al. Krupke, C. H., A. M.Alford, E. M.Cullen, E. W.Hodgson, J. J.Knodel, B.McCornack, B. D.Potter, M. I.Spigler, K.Tilmon, and K. Welch. Cypermethrin is a pyrethroid insecticide that mainly affects an insectâs central nervous system, used against a number of insect pests such as aphids, weevils, caterpillars, yellow cereal fly, flea beetles, â¦ Measure out the required quantity of CYPERMETHRIN 200 EC and premix this with at least 10 litres of water. Aphids, like other insects, employ several different mechanisms (i.e., metabolic resistance mediated by monooxygenases, esterases, and glutathione S-transferases; target site insensitivity such as knock down resistance (kdr) and super-kdr; and reduced cuticular penetration) to overcome pyrethroid insecticides (Liu 2012). Xi, J., Y. Pan, R. Bi, X. Gao, X. Chen, T. Peng, M. Zhang, H. Zhang, X. Hu, and Q. Shang. The geographic scope of field failures of pyrethroids for soybean aphid expanded in 2017, including Minnesota, North Dakota, and South Dakota (Fig. Resistance can be defined as a ‘genetically based decrease in susceptibility to a pesticide’ and more than 500 species of arthropods have developed resistance to insecticides (Tabashnik et al. We thank Anthony Hanson and three anonymous reviewers for providing critical reviews of an earlier version of this paper and Courtney Garrison for summary of the USDA data. Aphid-resistant soybean varieties have proven effective for soybean aphid management, particularly when multiple resistance (Rag) genes are pyramided in individual lines (Hesler et al. A., S. J. Bhusal, A. Lorenz, and R. L. Koch. A popular insecticide active ingredient that is used to eliminate a broad range of common household bugs is a synthetic pyrethroid known as Cypermethrin. Use of reduced rates of insecticide or improper use resulting in drift can result in aphids being exposed to low doses of insecticide, which can further increase selection pressure. They have â¦ We also thank James Menger, Ian MacRae, Philip Glogoza, Anitha Chirumamilla, John Gavloski, Patrick Beauzay, and Lesley Lubenow for assistance with our survey efforts in 2017.

In contrast, recommendations for the use of mixtures are prominent in programs for herbicide resistance management (NRC 2012). Tabashnik, B. E., D. Mota-Sanchez, M. E. Whalon, R. M. Hollingworth, and Y. Carriere. In China, laboratory experiments exposing soybean aphid to lambda-cyhalothrin for 40 generations resulted in the development of 76-fold resistance to that insecticide and cross resistance â¦ Unnecessary exposure of soybean aphid to insecticides can result from tank mixing insecticide with other pesticide applications regardless of soybean aphid populations. However, pyrethroid-containing mixtures should generally be avoided for use against pyrethroid-resistant populations (IRAC 2012) (Fig. In China, laboratory experiments exposing soybean aphid to lambda-cyhalothrin for 40 generations resulted in the development of 76-fold resistance to that insecticide and cross resistance to other pyrethroids (i.e., cypermethrin, esfenvalerate, cyfluthrin, and bifenthrin), organophosphates (i.e., chlorpyrifos and acephate), and a carbamate (i.e., carbofuran) (Xi et al. In particular, the area of southwest Minnesota (i.e., Blue Earth, Brown, Cottonwood, Faribault, Martin, Redwood, Renville, and Watonwan counties) from which pyrethroid performance issues were first reported (Hanson et al. The LC5 of beta-cypermethrin accelerated the reproductive inhibition. Although multiple pest management tactics are available, such as host-plant resistance and biological control, current management continues to rely almost exclusively on foliar insecticides (Hodgson et al. In response to the challenges that insecticide-resistant soybean aphids pose, growers, consultants and applicators are encouraged to evaluate and select their soybean aphid management practices carefully. Koch, R. L., B. D. Potter, P. A. Glogoza, E. W. Hodgson, C. H. Krupke, J. F. Tooker, C. D. DiFonzo, A. P. Michel, K. J. Tilmon, T. J. Prochaska, et al. 2011, Hodgson et al. However, soybean aphid management has relied primarily on organophosphates (Group 1B) and pyrethroids (Group 3A) (Hodgson et al. Cypermethrin is a synthetic pyrethroid insecticide used to kill insects on cotton and lettuce, and to kill cockroaches, fleas, and termites in houses and other buildings. These findings hinted that the pyrethroid insecticide beta-cypermethrin has the potential to mediate the interspecific competition between specialist and generalist aphids (at the sublethal concentration of LC5), and that it could influence aphid population growth and community structure in soybean crops. 2012), which has increased selection pressure for these particular groups. Due to the paucity of insecticide groups available for soybean aphid management, IRM will be essential in prolonging the effectiveness of these chemical tools. Selective insecticides (i.e., toxic to pest, but less toxic to natural enemies), such as flonicamid (Group 29) (Bahlai et al. 2013). However, many of these natural enemies are also adversely affected by broad-spectrum insecticides (e.g., organophosphates and pyrethroids) currently used to manage soybean aphid. Examples of foliar insecticides labeled for soybean aphid management1. As a synthetic pyrethroid, Zeta-Cypermethrin is a contact insecticide which provides quick results for â¦ Over recent years, the percentage of soybean acres that have been treated with insecticides, not including seed treatments, has been highest in Minnesota, followed by Iowa and North Dakota compared to other states in the Midwest Region (Fig. If more than one treatment is needed in the same growing season, alternate to a different insecticide group number. For example, host-plant resistance is the cornerstone for many pest management programs (Smith 2005), but is largely lacking in soybean aphid management. Zeta-cypermethrin is a synthetic pyrethroid used as a contact insecticide. Hodgson, E. W., B. P. McCornack, K. J. Tilmon, and J. Knodel. Frewin, A. J., A. W. Schaafsma, and R. H. Hallett. This knowledge could contribute to rationalize application of insecticides and to optimize Integrated Pest Management in soybean. Furthermore, research has shown that natural enemies (i.e., predators, parasitic wasps, and entomopathogenic fungi) can play an important role in prevention and suppression of soybean aphid outbreaks (Koch et al. 2014). 2018, Varenhorst and Wagner 2018) (Table 1). - Cypermethrin is a synthetic pyrethroid. and Environment Extension Publications, A nematode, fungus, and aphid interact via a shared host plant: implications for soybean management, One gene versus two: a regional study on the efficacy of single gene versus pyramided resistance for soybean aphid management, National Agricultural Statistics Service (NASS), Pesticide resistance: strategies and tactics for management, National Summit on strategies to manage herbicide-resistant weeds: proceedings of a workshop, Impact of reduced-risk insecticides on soybean aphid and associated natural enemies, Maintaining genetic diversity and population panmixia through dispersal and not gene flow in a holocyclic heteroecious aphid species, Compatibility of flonicamid and a formulated mixture of pyrethrins and azadirachtin with predators for soybean aphid (Hemiptera: Aphididae) management, Economic threshold for soybean aphid (Hemiptera: Aphididae), Ecology and management of the soybean aphid in North America, Acute-contact and chronic-systemic in vivo bioassays: regional monitoring of susceptibility to thiamethoxam in soybean aphid (Hemiptera: Aphididae) populations from the North Central United States, Plant resistance to arthropods: molecular and conventional approaches, Defining terms for proactive management of resistance to Bt crops and pesticides, Potential for sulfoxaflor to improve conservation biological control of, The response of natural enemies to selective insecticides applied to soybean, 2018 South Dakota pest management guide: soybeans. 1Based on review of soybean production guides from the Upper Midwest (Knodel et al. 2012b, Clifton et al. Control of Cucurbit Insects. Insecticide Resistance Action Committee (IRAC). In the short term, however, cost-effective management of soybean aphid will continue to rely on scouting and threshold-based insecticide applications of the few labeled insecticide groups (Table 1, Fig. Aphids will unknowingly land on the treated plant, start to feed and within a few days die. Moreover, the two species showed different spatial distribution on soybean seedlings. In 2016 and 2017, further reports of failures of pyrethroid insecticides and/or laboratory confirmation of resistance occurred in Iowa, North Dakota, South Dakota, and Manitoba. 2014). When selecting insecticides, keep in mind that the ‘the primary intention for the use of an insecticide mixture (tank-mix or pre-formulated mixture) is, in most cases, not resistance management but pest management’ (IRAC 2012). A., J. Menger-Anderson, C. Silverstein, B. D. Potter, I. V. MacRae, E. W. Hodgson, and R. L. Koch. Aphids from these three populations were less sensitive to alpha-cypermethrin compared with KAT (Figure 3). Orantes, L. C., W.Zhang, M. A. R.Mian, and A. P. Michel. If a soybean field exceeds the economic threshold, use an effective insecticide at a labeled rate (IRAC 2009) (Fig. The LC5 of beta-cypermethrin drove A.Â solani migrating from soybean leaves to stems independently of interspecific competition. Cypermethrin is toxic to the nervous â¦ In the long term, soybean aphid management must move beyond insecticide-based management toward true integrated pest management incorporating multiple, proactive tactics. Title: Microsoft Word - Insecticide_Selection_Sugarcane_Aphid_2015.docx Created Date: 6/23/2015 8:08:16 PM 2016) and biotypes of soybean aphid able to survive on some aphid-resistant soybean have been identified (Hesler et al. 1) (Koch et al. For the last 17 yr, soybean aphid management has relied almost entirely on the use of foliar-applied broad-spectrum insecticides. We provide an overview of factors that may have contributed to development of insecticide resistance in soybean aphid and recommendations for management of potentially resistant soybean aphid populations. The biology, impacts, and management of soybean aphid have been well reviewed (Ragsdale et al. © The Author(s) 2018. 2012a, Hanson et al. Insecticide resistance in soybean aphid has emerged as a new challenge to soybean production. 2).

Use the economic threshold (i.e., 250 aphids per plant with more than 80% of plants infested and aphid populations increasing) to determine if insecticides should be applied (Ragsdale et al. The most popular among gardeners means to control aphids on apple trees are the following drugs: Kinmiks is an insecticide that contains the main active ingredient beta-cypermethrin (from the group of pyrethroids, it is produced artificially), it affects both adult aphids â¦ If insecticide resistance is not suspected in the aphid population, then the choice of insecticide could include the various labeled products (Table 1, Fig. Schmidt, N. P., M. E. O’Neal, P. F. Anderson, D. Lagos, D. Voegtlin, W. Bailey, P. Caragea, E. Cullen, C. DiFonzo, K. Elliot, et al. 3). 2018, Varenhorst and Wagner 2018). (2017) provided the first evidence for soybean aphid resistance to insecticides coupled with reports of these insecticides failing to control the pest in North America. Copyright Â© 2021 Elsevier B.V. or its licensors or contributors. Third, failure to use proper scouting methods and established thresholds for the determination of when to apply insecticides can result in aphids being exposed to insecticides more frequently than necessary. Application of insecticides for soybean aphid below the economic threshold is unlikely to provide economic benefit and will subject the pest to unnecessary insecticide exposure and allow further selection pressure for resistance (Koch et al. 2012). 2012, Krupke et al. 2007).
