States included had data available for the three survey years. To minimize drift, which could result in an effectively reduced rate of insecticide in the field, only spray under favorable environmental conditions (e.g., wind speeds less than 10 miles per hour, no air temperature inversions). However, scouting and threshold-based application of foliar insecticides provides a greater likelihood and magnitude of positive net return than seed-applied insecticides for management of soybean aphid (Krupke et al. 2017). 2011, Hodgson et al. Hodgson, E. W., E. C. Burkness, W. D. Hutchison, and D. W. Ragsdale. Nicotinic acetylcholine receptor agonists, Copyright © 2021 Entomological Society of America. 2018, Varenhorst and Wagner 2018) (Table 1). However, in an assessment of the susceptibility of soybean aphid populations from the North Central Region to the neonicotinoid, thiamethoxam, Ribeiro et al. and B.D.P., unpublished data). The LC5 of beta-cypermethrin drove A.Â solani migrating from soybean leaves to stems independently of interspecific competition. Aphis glycines mainly aggregated on the stem of soybean plant while A.Â solani colonized soybean leaves. Monitor the trees for mites when the weather is hot and dry and after â¦ Insecticide use on soybean in North America has increased dramatically in response to this pest (Ragsdale et al. Not all failures of insecticides are due to insecticide resistance. McCarville, M. T., M. O’Neal, G. L. Tylka, C. Kanobe, and G. C. MacIntosh. 2015). Published by Oxford University Press on behalf of Entomological Society of America. 2004, Hodgson et al. 2015). 2015), could further increase the use of scouting-based decision making for soybean aphid management. 1) (Koch et al. Tran, A. K., T. M. Alves, and R. L. Koch. From 2015 to 2016, soybean aphid populations from Minnesota and Iowa exhibited resistance ratios up to 40-fold for pyrethroids (i.e., bifenthrin and lambda-cyhalothrin) (Hanson et al. A., J. Menger-Anderson, C. Silverstein, B. D. Potter, I. V. MacRae, E. W. Hodgson, and R. L. Koch. If a soybean field exceeds the economic threshold, use an effective insecticide at a labeled rate (IRAC 2009) (Fig. Beckendorf, E. A., M. A. Catangui, and W. E. Riedell. It readily decomposes when exposed to sunlight. Measure out the required quantity of CYPERMETHRIN 200 EC and premix this with at least 10 litres of water. Soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), continues to be the most significant insect pest of soybean, Glycine max (L.) Merr., in the Upper Midwest of the United States (Hurley and Mitchell 2017). Hodgson, E. W., B. P. McCornack, K. A. Koch, D. W. Ragsdale, K. D. Johnson, M. E. O’Neal, E. M. Cullen, H. J. Kraiss, C.

McCreary, A. W. Schaafsma, and R. H. Hallett. Report suspected cases of insecticide-resistant soybean aphids to a local/regional extension educator or extension entomologist. 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. Aphis glycines mainly colonized the soybean stem while A.Â solani prefers the foliage. 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. 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. 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. Aphis glycines showed higher fecundity than A.Â solani on soybean and the aphids caused unbalanced reduction in population growth on each other. Insecticide Resistance Action Committee (IRAC). 2012), which has increased selection pressure for these particular groups. Finally, if soybean is in bloom, consider insecticide options with reduced risk to pollinators (Zhu et al. Alternatively, ‘Speed Scouting’ can be used as a more efficient approach to scouting and making treatment decisions (Hodgson et al. The LC5 of beta-cypermethrin accelerated the reproductive inhibition. If a field needs to be retreated, alternate to a different insecticide group for the follow-up application (NRC 1986, IRAC 2009) (Fig. Cypermethrin is a synthetic pyrethroid insecticide. Tilmon, K. J., E. W. Hodgson, M. E. O’Neal, and D. W. Ragsdale.

Insecticide â¦ zeta-cypermethrin) 5.0 to 11.75 fl oz : Tombstone [3] (cyfluthrin) 1.8 to 2.4 fl oz (0.028 to 0.038 fl oz/A) Greenbug: Planting Time : Lime-green aphid with darker green stripe down back. 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. Among these, management has relied primarily on foliar applications of pyrethroids (Group 3A) and organophosphates (Group 1B) since detection of this pest (Hodgson et al. In agroecosystems, plant-pest interactions are at the basis of complex food webs, which can be affected by both biotic and abiotic factors. Mites may increase after some insecticides (esfenvalerate, permethrin, zeta-cypermethrin) are applied for control of other pests. 3). Since the first observation of soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), in North America in 2000, it has become the most economically damaging insect of soybean in the Upper Midwest of the United States. However, soybean aphid management has relied primarily on organophosphates (Group 1B) and pyrethroids (Group 3A) (Hodgson et al. 2012, Pezzini and Koch 2015), pymetrozine (Group 9B) (Ohnesorg et al. 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. It is used in the UK to control a range of pests in both arable and livestock farming, in homes and gardens, and in public and commercial buildings. 2004). Table 1 lists the natural and conventional contact insecticides for the â¦ Economically significant infestation of soybean by this phloem-feeding insect can reduce soybean yield by up to 40% (Ragsdale et al. Additional research in China has shown that soybean aphid can overcome insecticides through increased esterase and cytochrome P450 expression, which may explain the cross resistance observed by Xi et al. Biological Control Methods: Parasitic wasps (small wasps that are harmless to humans) are the best for killing aphids. 2007). 2011, Tilmon et al. This graphic was modified from Hodgson and Koch (2018). Hodgson, E. W., B. P. McCornack, K. J. Tilmon, and J. Knodel. 2011, 2012). 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. The LC50 values across all nine populations ranged from 0.6 to 24.57mg a.i./L. Sampling recommendations were developed and validated to estimate soybean aphid abundance (Hodgson et al. Insecticides from three insecticide groups are available in foliar formulations for soybean aphid management (IRAC 2018, Knodel et al. Hanson, A. The amount of cypermethrin â¦ This area of Minnesota also receives significant numbers of pyrethroid insecticide applications to canning crops, which are often adjacent to soybean. Ants ward off natural aphid enemies, so ant control is an important aspect of aphid control. Second, as indicated earlier, there are a limited number of insecticide groups available for soybean aphid management (Table 1). It can be used 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. 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. Orantes, L. C., W.Zhang, M. A. R.Mian, and A. P. Michel. Numerous aphid species, including those in the genus Aphis, have developed resistance to several groups of insecticides (Foster et al. South Dakota State University Extension, Research on resistance of soybean aphid (, The soybean aphid in China: a historical review, Elevated expression of esterase and cytochrome P450 are related with lambda-cyhalothrin resistance and lead to cross resistance in, Spray toxicity and risk potential of 42 commonly used formulations of row crop pesticides to adult honey bees (Hymenoptera: Apidae). Populations of clonally reproducing aphids in such fields may have already been exposed to this systemic, seed-applied insecticide. In response to the challenge posed by insecticide-resistant soybean aphids, we recommend several management strategies for minimizing further development of resistance and subsequent pest-induced crop losses: 1) scout and use the economic threshold to determine when to apply insecticides, 2) apply the insecticides properly, 3) assess efficacy 3–5 d after application, and 4) alternate to a different insecticide group if another application is required. Now if you treat mid or late season, you will get control of any current problem but it would be smart to apply more the following spring. In the long term, soybean aphid management must move beyond insecticide-based management to true integrated pest management by incorporating multiple tactics. A popular insecticide active ingredient that is used to eliminate a broad range of common household bugs is a synthetic pyrethroid known as Cypermethrin. 2004, Ragsdale et al. 2017) has had chronically high soybean aphid populations (i.e., exceeding the economic threshold) every year, except 2003.

Due to the mobility of winged soybean aphids (Schmidt et al. (2011) found no resistance to organophosphates, pyrethroids, or neonicotinoids in field-collected soybean aphid populations from Michigan in 2007 and 2008. When making insecticide applications, use appropriate nozzles, water volumes, and pressures to ensure thorough spray coverage deep into the soybean canopy (IRAC 2009, Hodgson et al. 2016). - Cypermethrin is a synthetic pyrethroid. 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. Foster, S. P., G. Devine, and A. L. Devonshire. Examples of foliar insecticides labeled for soybean aphid management1. 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. Hanson, A. Reliance on insecticide-based management of insect pests often results in development of insecticide resistance (Pedigo and Rice 2009). 2010, Frewin et al. 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. 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). 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.

Updated February 9, 2017 Economic Threshold: The recommended threshold for late vegetative through R5 stage soybeans is 250 aphids per plant (field average) with 80% of the plants infested and â¦ The continued validity of the 250-aphid-per-plant threshold is explained by Koch et al. In addition, an economic threshold of 250 aphids per plant with more than 80% of plants infested and aphid populations increasing was developed to optimize use of foliar insecticides for soybean aphid management (Ragsdale et al. If pyrethroid-resistance is suspected in an aphid population, products containing insecticides other than pyrethroids should be considered. 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. Increasingly, widespread detections of pyrethroid resistance in soybean aphid populations in the Upper Midwest of the United States (Hanson et al. Clifton, E. H., G. L. Tylka, and A. J. Gassmann, and E. W. Hodgson. 2012, Varenhorst and O’Neal 2012), and sulfoxaflor (Group 4C) (Tran et al. We are unaware of reports of neonicotinoids failing to control soybean aphid in the field. 2018) have created an immediate challenge for effective soybean pest management and profitable soybean production. Beta-cypermethrin, a synthetic pyrethroid pesticide, has a broad insecticide spectrum and is considered effective for aphid control, while its residual concentrations may have sublethal effects â¦ McCarville, M. T., M. E. O’Neal, and E. W. Hodgson. Synthetic pyrethroids are man-made insecticides created to mimic the chemical properties of â¦ 2016) and biotypes of soybean aphid able to survive on some aphid-resistant soybean have been identified (Hesler et al. Pyrethroid-containing mixtures may provide adequate control of some pyrethroid-resistant populations of soybean aphid (IRAC 2012, R.L.K. In contrast, recommendations for the use of mixtures are prominent in programs for herbicide resistance management (NRC 2012). 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¦ 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¦ 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. Soybean aphid also can affect soybean through transmission of viruses (e.g., Soybean mosaic virus and Alfalfa mosaic virus) (Hill et al. 2007). Thrips. Zeta-cypermethrin is a synthetic pyrethroid used as a contact insecticide. (2016).

Improvements in the efficiency of soybean aphid scouting, such as the potential for remote sensing (Alves et al. 2004, Wu et al. Insecticide options are given as examples only and do not imply endorsement of one insecticide versus another nor discrimination against any insecticide not mentioned by the authors or the universities. Reproduction of A.Â glycines was more likely inhibited by the interspecific interactions compared to A.Â solani. Agric. This knowledge could contribute to rationalize application of insecticides and to optimize Integrated Pest Management in soybean. Aphids can be green, brown, golden, orange, red, white, grey or black. 3). Add this to the spray tank while agitating the mixture. 2016). For example, if a field was treated with a pyrethroid (Group 3A) and a follow-up insecticide application is needed, then an insecticide from different insecticide group, such as an organophosphate (Group 1B), should be selected. It is low toxicity to humans and animals. 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).
