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. Zeta-Cypermethrin. Measure out the required quantity of CYPERMETHRIN 200 EC and premix this with at least 10 litres of water. Hanson, A.

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. Knodel, J. J., P. Beauzay, M. Boetel, and T. Prochaska. © The Author(s) 2018. To reduce the selection pressure for development of resistance to insecticides, treat fields only when necessary (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. Beckendorf, E. A., M. A. Catangui, and W. E. Riedell. 3). Aphis glycines facilitated A. solani colonization on soybean plant through impacting host susceptibility, and vice versa. Reproduction of A. glycines was more likely inhibited by the interspecific interactions compared to A. solani. Not all failures of insecticides are due to insecticide resistance. Yards which develop pests like aphids … Hanson et al. 2004). 2011, Coupe and Capel 2016). 2007). It can be used They lay an egg inside an aphid, where the larvae eat the aphid … 2010, Frewin et al. Second, as indicated earlier, there are a limited number of insecticide groups available for soybean aphid management (Table 1). 3). Seed treatments containing neonicotinoids (Group 4A) are also commonly used in soybean (Hodgson et al. ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. 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. The LC5 of beta-cypermethrin drove A. solani migrating from soybean leaves to stems independently of interspecific competition. In the United States, Chandrasena et al. 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. 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. 2004, Hodgson et al. 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. 2012b, Clifton et al. (2015). National Agricultural Statistics Service (NASS). Examples of foliar insecticides labeled for soybean aphid management1. Sampling recommendations were developed and validated to estimate soybean aphid abundance (Hodgson et al. Nevertheless, such facilitated colonization-induced susceptibility could be modulated through exposure to the LC5 of beta-cypermethrin. 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. 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 … 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. 2015), could further increase the use of scouting-based decision making for soybean aphid management. In response to the challenge posed by insecticide-resistant soybean aphid, we recommend several management strategies for minimizing further development of resistance and subsequent pest-induced crop losses. For example, host-plant resistance is the cornerstone for many pest management programs (Smith 2005), but is largely lacking in soybean aphid management. Aphis glycines mainly aggregated on the stem of soybean plant while A. solani colonized soybean leaves. 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. Hodgson, E. W., B. P. McCornack, K. J. Tilmon, and J. Knodel. Ants ward off natural aphid enemies, so ant control is an important aspect of aphid control. 2017) has had chronically high soybean aphid populations (i.e., exceeding the economic threshold) every year, except 2003. 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. 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. Numerous aphid species, including those in the genus Aphis, have developed resistance to several groups of insecticides (Foster et al. 1) (Koch et al. It readily decomposes when exposed to sunlight. 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. Literature from Asia indicates ‘light’ levels of field-evolved resistance of soybean aphid to organophosphates (Wang et al. If insecticide resistance is not suspected in the aphid population, then the choice of insecticide could include the various labeled products (Table 1, Fig. Harlequin bugs, stink bugs, flea beetles and … Ohnesorg, W. J., K. D. Johnson, and M. E. O’Neal. 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. Table 1 lists the natural and conventional contact insecticides for the … 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 … 2017). Alternatively, ‘Speed Scouting’ can be used as a more efficient approach to scouting and making treatment decisions (Hodgson et al. Bahlai, C. A., Y. Xue, C. M. McCreary, A. W. Schaafsma, and R. H. Hallett. Hill, J. H., R. Alleman, D. B. Hogg, and C. R. Grau. Insecticide Resistance Action Committee (IRAC). 3). 2012). Biological Control Methods: Parasitic wasps (small wasps that are harmless to humans) are the best for killing aphids. 2According to Insecticide Resistance Action Committtee (IRAC 2018). 2007) through decreased number of pods and seeds, and smaller seed size (Beckendorf et al. If pyrethroid resistance is suspected in the aphid population, application of pyrethroid-containing mixtures (e.g., options C and D) may provide pest control, but the pyrethroid component of the product is compromised by resistance and use may provide additional selection pressure for further development of insecticide resistance.

These continued infestations by soybean aphid in parts of the Upper Midwest have resulted in a long history (i.e., about 17 yr) of selection pressure for development of insecticide resistance. 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. 2012). 3). Ribeiro, M. G. P. M., T. E. Hunt, and B. D. Siegfried. States included had data available for the three survey years. Insecticides from three insecticide groups are available in foliar formulations for soybean aphid management (IRAC 2018, Knodel et al. A popular insecticide active ingredient that is used to eliminate a broad range of common household bugs is a synthetic pyrethroid known as Cypermethrin. 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. Synthetic pyrethroids are man-made insecticides created to mimic the chemical properties of … 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. 2015). This graphic was modified from Hodgson and Koch (2018). In agroecosystems, plant-pest interactions are at the basis of complex food webs, which can be affected by both biotic and abiotic factors. 3). Koch, K., B. D. Potter and D. W. Ragsdale. 3). 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. Hodgson, E. W., E. C. Burkness, W. D. Hutchison, and D. W. Ragsdale. Unnecessary exposure of soybean aphid to insecticides can result from tank mixing insecticide with other pesticide applications regardless of soybean aphid populations. As a synthetic pyrethroid, Zeta-Cypermethrin is a contact insecticide which provides quick results for … 2012, Krupke et al. The biology, impacts, and management of soybean aphid have been well reviewed (Ragsdale et al. McCarville, M. T., M. E. O’Neal, and E. W. Hodgson. Red-shaded counties indicate those from which reports of pyrethroid failures were received. Such a facilitated colonization was impaired by the LC5 of beta-cypermethrin. A., S. J. Bhusal, A. Lorenz, and R. L. Koch. 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). 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. Mites may increase after some insecticides (esfenvalerate, permethrin, zeta-cypermethrin) are applied for control of other pests. 2010, Ragsdale et al. However, the LC 5 of beta-cypermethrin enhanced the interspecific inhibition of fecundity between the two aphid … CHLORPYRIFOS (LORSBAN, NUFOS, YUMA) is available in several formulations registered for use as a foliar application in the dormant or delayed dormant period against aphids and scale in apples, scale … 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 … However, pyrethroid-containing mixtures should generally be avoided for use against pyrethroid-resistant populations (IRAC 2012) (Fig. 2012, Pezzini and Koch 2015), pymetrozine (Group 9B) (Ohnesorg et al. Soybean aphid also can affect soybean through transmission of viruses (e.g., Soybean mosaic virus and Alfalfa mosaic virus) (Hill et al. This pattern of greater pest pressure in Minnesota and neighboring states is further evidenced by data from NASS (2018). 2012), the risk of insecticide-resistant populations of soybean aphid spreading to soybean fields in other soybean producing regions is high. This area of Minnesota also receives significant numbers of pyrethroid insecticide applications to canning crops, which are often adjacent to soybean. Cypermethrin is toxic to the nervous … 2016). Selective insecticides (i.e., toxic to pest, but less toxic to natural enemies), such as flonicamid (Group 29) (Bahlai et al. 2017). Currently, any populations of soybean aphid should be considered potentially resistant to pyrethroids. 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. We are unaware of reports of neonicotinoids failing to control soybean aphid in the field. Cypermethrin is bio-degradable in soil and plants, but its effects can extend for weeks when applied to indoor inert surfaces. 3). Moreover, the two species showed different spatial distribution on soybean seedlings. In the long term, soybean aphid management must move beyond insecticide-based management to true integrated pest management by incorporating multiple tactics. In addition, the amount of each active ingredient in some mixtures is less than that of products with single active ingredients. 2017). Finally, if soybean is in bloom, consider insecticide options with reduced risk to pollinators (Zhu et al. Ragsdale, D. W., B. P. McCornack, R. C. Venette, B. D. Potter, I. V. MacRae, E. W. Hodgson, M. E. O’Neal, K. D. Johnson, R. J. O’Neil, C. D. DiFonzo, et al. Image from Koch et al. 2012). The field rate of alpha-cypermethrin (125 mg a.i./L) controlled 98%, 93% and 90% of aphids … 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). 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.

The LC5 of beta-cypermethrin accelerated the reproductive inhibition. 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. Due to the mobility of winged soybean aphids (Schmidt et al. Xi, J., Y. Pan, R. Bi, X. Gao, X. Chen, T. Peng, M. Zhang, H. Zhang, X. Hu, and Q. Shang. 2016). 2009), spirotetramat (Group 23) (Bahlai et al. 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. 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. 2012, Varenhorst and O’Neal 2012), and sulfoxaflor (Group 4C) (Tran et al. 2007, Koch et al. Aphids will unknowingly land on the treated plant, start to feed and within a few days die. 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. 2017). Cypermethrin is a pyrethroid insecticide that mainly affects an insect’s central nervous system, used against a number of insect pests such as aphids, weevils, caterpillars, yellow cereal fly, flea beetles, … What is Cypermethrin?

Aphis glycines mainly colonized the soybean stem while A. solani prefers the foliage. Improvements in the efficiency of soybean aphid scouting, such as the potential for remote sensing (Alves et al. Tips of legs, … Foster, S. P., G. Devine, and A. L. Devonshire. Insecticide resistance in soybean aphid has emerged as a new challenge to soybean production. Wu, Z., D. Schenk-Hamlin, W. Zhan, D. W. Ragsdale, and G. E. Heimpel. (2016). 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). 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. 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). Tran, A. K., T. M. Alves, and R. L. Koch. 2011, 2012). 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. 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. Fill the spray tank while maintaining … Upon reaching threshold, treat the field within 5–7 d to protect yield (Ragsdale et al. Insecticide use on soybean in North America has increased dramatically in response to this pest (Ragsdale et al.
