However, the LC 5 of beta-cypermethrin enhanced the interspecific inhibition of fecundity between the two aphid … The biology, impacts, and management of soybean aphid have been well reviewed (Ragsdale et al. Furthermore, reports of pyrethroids failing to control soybean aphid in the field were noted from Minnesota and Iowa (Hanson et al. Knodel, J. J., P. Beauzay, M. Boetel, and T. Prochaska. Alternation of individual insecticide groups is generally preferred for insecticide resistance management (IRM) (IRAC 2012). 2007) through decreased number of pods and seeds, and smaller seed size (Beckendorf et al. (2016). 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. and B.D.P., unpublished data).

Unnecessary exposure of soybean aphid to insecticides can result from tank mixing insecticide with other pesticide applications regardless of soybean aphid populations. 2017). Insecticide use on soybean in North America has increased dramatically in response to this pest (Ragsdale 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. 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). 2). 2016). Finally, if soybean is in bloom, consider insecticide options with reduced risk to pollinators (Zhu et al. 3). Tabashnik, B. E., D. Mota-Sanchez, M. E. Whalon, R. M. Hollingworth, and Y. Carriere. However, in an assessment of the susceptibility of soybean aphid populations from the North Central Region to the neonicotinoid, thiamethoxam, Ribeiro et al. 2004, Hodgson et al. Harlequin bugs, stink bugs, flea beetles and … 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. Tran, A. K., T. M. Alves, and R. L. Koch. 2009), spirotetramat (Group 23) (Bahlai et al. This graphic was modified from Hodgson and Koch (2018). 2012). 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. D. DiFonzo, M. Jewett, et al. Once aphid populations become established in a crop, higher rates of insecticides are required to reduce high aphid populations and to minimise their feeding damage. Currently, any populations of soybean aphid should be considered potentially resistant to pyrethroids. Alternatively, ‘Speed Scouting’ can be used as a more efficient approach to scouting and making treatment decisions (Hodgson et al. (2011) found no resistance to organophosphates, pyrethroids, or neonicotinoids in field-collected soybean aphid populations from Michigan in 2007 and 2008. 3Insecticides 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. Zeta-Cypermethrin is one of the newer synthetic pyrethroids on the market. 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. Beckendorf, E. A., M. A. Catangui, and W. E. Riedell. 2012) with varying levels of insecticide susceptibility colonizing the fields. Due to the paucity of insecticide groups available for soybean aphid management, IRM will be essential in prolonging the effectiveness of these chemical tools. In the United States, Chandrasena et al. Beta-cypermethrin is classified as a toxicity class II (pyrethroid) insecticide, and it represents one of the main options for controlling aphids on cereals in China (Zhang et al. 2018, Varenhorst and Wagner 2018). First, economically threatening infestations of soybean aphid continue to occur in Minnesota and portions of Iowa, North Dakota, and South Dakota (R.L.K., B.D.P., E.W.H., J.J.K., and A.J.V., personal observations), while such infestations have diminished in other parts of the United States (Bahlai et al. 1Based on review of soybean production guides from the Upper Midwest (Knodel et al. 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. 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. Koch, R., E. Hodgson, J. Knodel, and A. Varenhorst. 2008). Hodgson, E. W., B. P. McCornack, K. J. Tilmon, and J. Knodel. Hanson, A. (2015). 2017) has had chronically high soybean aphid populations (i.e., exceeding the economic threshold) every year, except 2003. 2017). 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. 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. Such a facilitated colonization was impaired by the LC5 of beta-cypermethrin. Moreover, the two species showed different spatial distribution on soybean seedlings. Hill, J. H., R. Alleman, D. B. Hogg, and C. R. Grau. 2015). 2017). Cypermethrin is bio-degradable in soil and plants, but its effects can extend for weeks when applied to indoor inert surfaces. 3). Due to the mobility of winged soybean aphids (Schmidt et al. In such situations, the pyrethroid component of such products may be compromised by the resistance. If fields were planted with neonicotinoid-treated seed, avoid application of neonicotinoid-containing products (e.g., options D and E) for the first foliar application to the field. 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. 1) (Koch et al. These authors contributed equally to this work. If insecticide resistance is not suspected in the aphid population, then the choice of insecticide could include the various labeled products (Table 1, Fig. 2001) and potential facilitation of soybean cyst nematode, Heterodera glycines Ichinohe, infestations (McCarville et al. 2004, Wu et al. Biological Control Methods: Parasitic wasps (small wasps that are harmless to humans) are the best for killing aphids. However, soybean aphid management has relied primarily on organophosphates (Group 1B) and pyrethroids (Group 3A) (Hodgson et al. Implementation of user-friendly scouting tools and other management tactics may decrease unnecessary exposure of the pest to insecticides and, in turn, reduce further development of insecticide resistance. 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 … In agroecosystems, plant-pest interactions are at the basis of complex food webs, which can be affected by both biotic and abiotic factors. 2010, Ragsdale et al. The recommended threshold to apply insecticide is 50% of cereal tillers have 15 or more aphids … Therefore, we caution against the use of neonicotinoid-containing insecticides for a first foliar application to such fields (Fig. Safer Brand 5118 Insect Killing Soap – 16-Ounce Concentrate. Increasingly, widespread detections of pyrethroid resistance in soybean aphid populations in the Upper Midwest of the United States (Hanson et al. McCarville, M. T., M. E. O’Neil, B. D. Potter, K. J. Tilmon, E. M. Cullen, B. P. McCornack, J. F. Tooker, and D. A. Prischmann-Voldseth. 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 … 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. 3). © The Author(s) 2018. Hanson et al. 3). If the insecticide application fails to control the pest population, try to rule out other potential causes for an insecticide failure, such as incorrect insecticide rate or application method, unfavorable environmental conditions, or recolonization of a treated field by winged soybean aphids. 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). Nicotinic acetylcholine receptor agonists, Copyright © 2021 Entomological Society of America. 2013, McCarville et al. 2011, Coupe and Capel 2016). 2004). 2007). In addition, the amount of each active ingredient in some mixtures is less than that of products with single active ingredients. 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. 2004, Ragsdale et al.

The field rate of alpha-cypermethrin (125 mg a.i./L) controlled 98%, 93% and 90% of aphids … Koch, K., B. D. Potter and D. W. Ragsdale. The geographic scope of field failures of pyrethroids for soybean aphid expanded in 2017, including Minnesota, North Dakota, and South Dakota (Fig. Published by Oxford University Press on behalf of Entomological Society of America. Control of Cucurbit Insects. Aphids are tiny pear-shaped, soft-bodied insects that suck the juices out of leaves, stems and tender plants– though some species attack lettuce roots and the woody parts of apple tree roots and limbs. 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. 2014). 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. Aphids can be green, brown, golden, orange, red, white, grey or black. 3). Furthermore, depending on factors such as relative efficacy, durations of residual activity, and levels of cross resistance, use of some mixtures could provide additional selection pressure for further development of insecticide resistance (IRAC 2012). However, in 2015 in Minnesota, failures of foliar-applied pyrethroid insecticides were reported and pyrethroid resistance was confirmed with laboratory bioassays using lambda-cyhalothrin and bifenthrin. 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. 3). By continuing you agree to the use of cookies. 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). Frewin, A. J., A. W. Schaafsma, and R. H. Hallett. This area of Minnesota also receives significant numbers of pyrethroid insecticide applications to canning crops, which are often adjacent to soybean. Thrips are extremely minute insects, usually less than 1/16 inch when full-grown. 2016), have been evaluated for soybean aphid management, and could potentially provide for better integration of chemical and biological controls for this pest. 2007, Koch 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. This pattern of greater pest pressure in Minnesota and neighboring states is further evidenced by data from NASS (2018). 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. 2012, Pezzini and Koch 2015), pymetrozine (Group 9B) (Ohnesorg et al. National Agricultural Statistics Service (NASS). After soybean aphid populations reach the economic threshold, a single application of a foliar insecticide is usually sufficient for soybean aphid management (Hodgson et al. 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. 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. 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. Economically significant infestation of soybean by this phloem-feeding insect can reduce soybean yield by up to 40% (Ragsdale 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. 2017). Aphis glycines facilitated A. solani colonization on soybean plant through impacting host susceptibility, and vice versa. Insecticide resistance in soybean aphid has emerged as a new challenge to soybean production. Add this to the spray tank while agitating the mixture. 2According to Insecticide Resistance Action Committtee (IRAC 2018). The LC50 values across all nine populations ranged from 0.6 to 24.57mg a.i./L. Numerous aphid species, including those in the genus Aphis, have developed resistance to several groups of insecticides (Foster et al. Aphids from these three populations were less sensitive to alpha-cypermethrin compared with KAT (Figure 3). Aphis glycines mainly aggregated on the stem of soybean plant while A. solani colonized soybean leaves. However, the emergence of insecticide-resistant soybean aphids means the scouting of soybean fields 3–5 d after application has now become even more important to determine if the insecticide has provided the expected level of pest control (Fig. 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. It is used to control chewing, sucking, and flying insects such as beetles, aphids, and other Lepidoptera. Not all failures of insecticides are due to insecticide resistance. - Cypermethrin is a synthetic pyrethroid. However, pyrethroid-containing mixtures should generally be avoided for use against pyrethroid-resistant populations (IRAC 2012) (Fig. 2008; Shuai & Wang 2005). 2007). Cypermethrin is a synthetic pyrethroid insecticide.

Sublethal effects of beta-cypermethrin modulate interspecific interactions between specialist and generalist aphid species on soybean, https://doi.org/10.1016/j.ecoenv.2020.111302. Soybean aphid has been actively managed since 2000, because of the potential for severe economic impact. We are unaware of reports of neonicotinoids failing to control soybean aphid in the field. Alves, T. M., I. V. MacRae, and R. L. Koch. 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. A popular insecticide active ingredient that is used to eliminate a broad range of common household bugs is a synthetic pyrethroid known as Cypermethrin. Ribeiro, M. G. P. M., T. E. Hunt, and B. D. Siegfried. Ragsdale, D. W., D. A. Landis, J. Brodeur, G. E. Heimpel, and N. Desneux. A sublethal concentration of beta-cypermethrin (LC5 for A. glycines) stimulated the reproduction of A. glycines but it did not impact the fecundity of A. solani. Sampling recommendations were developed and validated to estimate soybean aphid abundance (Hodgson et al. 2007). 2016). If pyrethroid-resistance is suspected in an aphid population, products containing insecticides other than pyrethroids should be considered. 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. Ants ward off natural aphid enemies, so ant control is an important aspect of aphid control. 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. 2016) and biotypes of soybean aphid able to survive on some aphid-resistant soybean have been identified (Hesler et al. Second, as indicated earlier, there are a limited number of insecticide groups available for soybean aphid management (Table 1).
