“…First, continue to identify new resistance genes to control multiple aphid biotypes. Over 3500 soybean germplasm accessions have been screened for soybean aphid resistance, with only 30 soybean accessions being identified as resistant and the number of the resistance genes mapping to similar regions in the genome (Hill et al, 2004a; Hill et al, 2004b; Mensah et al, 2005; Diaz‐Montano et al, 2006; Mian et al, 2008a; Jun et al, 2012; Bansal et al, 2013; Fox et al, 2014 Hesler, 2013; Jun et al, 2013; Kim et al, 2014; Xiao et al, 2013; Bhusal et al, 2014; Liu et al, 2014). This approach may not be feasible owing to the limited ability of finding new resistant soybean accessions, quick adaptation of soybean aphid, and the time needed to identify, map, and genetically characterize resistance genes and incorporate them into commercial cultivars via marker‐assisted selection.…”

“…Host‐plant resistance offers an additional complementary management tactic in an overall integrated pest management program. More than 3500 soybean accessions were screened, resulting in the identification of only 30 soybean accessions with either antixenosis‐ and/or antibiosis‐type resistance to the soybean aphid (Hill et al, 2004a,b; Mensah et al, 2005; Diaz‐Montano et al, 2006; Mian et al, 2008a; Jun et al, 2012; Bansal et al, 2013; Fox et al, 2014; Hesler et al, 2013; Jun et al, 2013; Kim et al, 2014; Xiao et al, 2013; Bhusal et al, 2014; Liu et al, 2014). Antixenosis‐based resistance refers to a nonpreference of insects for behaviors like feeding and oviposition that can result in the poor establishment of an insect (Smith, 1989).…”

Geographic Distribution of Soybean Aphid Biotypes in the United States and Canada during 2008–2010

Soybean aphid (Aphis glycines Matsumura) is a native pest of soybean [Glycine max (L.) Merr.] in eastern Asia and was detected on soybeans in North America in 2000. In 2004, the soybean cultivar Dowling was described to be resistant to soybean aphids with the Rag1 gene for resistance. In 2006, a virulent biotype of soybean aphid in Ohio was reported to proliferate on soybeans with the Rag1 gene. The objective was to survey the occurrence of virulent aphid populations on soybean indicator lines across geographies and years. Nine soybean lines were identified on the basis of their degree of aphid resistance and their importance in breeding programs. Naturally occurring soybean aphid populations were collected in 10 states (Kansas, Illinois, Indiana, Iowa, Michigan, Minnesota, North Dakota, Ohio, South Dakota, and Wisconsin) and the Canadian province of Ontario. The reproductive capacity of field‐collected soybean aphid populations was tested on soybean lines; growth rates were compared in no‐choice field cages at each geographic region across 3 yr. The occurrence of soybean aphid biotypes was highly variable from year to year and across environments. The frequency of Biotypes 2, 3, and 4 was 54, 18, and 7%, respectively, from the 28 soybean aphid populations collected across 3 yr and 11 environments. Plant introduction (PI) 567598B, a natural gene pyramid of rag1c and rag4, had lowest frequency of soybean aphid colonization (18%). Several factors may have contributed to the variability, including genetic diversity of soybean aphids, parthenogenicity, abundance of the overwintering host buckthorn (Rhamnus spp.), and migratory patterns of soybean aphids across the landscape.

“…2). Furthermore, it was reported that PI 200538 (Rag2) expressed resistance to aphid biotype 3 at 21 and 28°C (Richardson, 2012), which directly contradicts the fact that the aphid biotype 3 was virulent on PI 200538 and has been maintained on other soybean genotypes with Rag2 as susceptible checks at temperatures within 21 to 28°C in several studies (Alt and Ryan-Mahmutagic, 2013;Bansal et al, 2013;Fox et al, 2014;Hill et al, 2010;Kim et al, 2014). Richardson also reported that the antixenosis-type resistance against aphid biotypes 1 and 3 in PI 567597C was reduced at 28°C, which was not found in this study (Fig.…”

The soybean aphid (Aphis glycines Matsumura) is the most important insect pest posing a threat to soybean [Glycine max (L.) Merr.] grain production in the United States. Soybean cultivars with resistance are currently being deployed to aid in management of the pest. Temperature has been reported to influence the expression of host plant resistance against crop pests. The objective of this study was to determine if temperatures, 14, 21, and 28°C, altered resistance expression in four aphid‐resistant soybean genotypes, LD05‐16611 (with the Rag1 resistance gene), PI 200538 (Rag2), PI 567541B (rag1c, rag4), and PI 567597C (antixenosis) compared to a susceptible soybean genotype (Williams 82) when challenged with soybean aphid. A replicated no‐choice experiment was conducted and aphid populations of the three soybean aphid biotypes, 1, 2, and 3, were enumerated 14 d after inoculating the five soybean genotypes. Significant interactions were found in the analysis of the effects of temperature, soybean genotype, and aphid biotype on aphid populations. Responses between soybean genotypes and aphid biotypes were consistent with previous reports with the exception of PI 567541B, which had lower resistance against aphid biotype 1 than found in an earlier study. At 14°C, there was limited aphid population growth on all soybean genotypes, including Williams 82. At 21 and 28°C, resistance expression was stable in LD05‐16611 (Rag1), PI 567541B (rag1c, rag4), and PI 567597C (antixenosis), relative to susceptible Williams 82; however, resistance expressed in PI 200538 (Rag2) was significantly stronger at 28°C than at 21°C, as indicated by differences in aphid population size that were found. Results of this study indicated that soybean aphid virulence variability had a stronger influence on the effectiveness of soybean aphid resistance than did temperature, and that the aphid resistance tested in this study would remain stable or be stronger in temperatures ranging between 21 and 28°C.

“…In the late spring or early summer, the aphids develop into alates (winged morphs) and migrate to soybean plants, where they feed primarily on the ventral surfaces of young leaves [12]. This results in plant stunting, leaf yellowing and wrinkling, reduced photosynthesis, poor pod fill, reduced seed size and quality, and yield reductions of up to 40% [13,14,15]. The aphids also act as a vector for various viruses ( Soybean mosaic virus , Alfalfa mosaic virus , and Bean yellow mosaic virus ) and facilitate sooty mold formations through the deposition of honeydew [5,16].…”

Soybean aphid (SBA; Aphis glycines Matsumura) and soybean cyst nematode (SCN; Heterodera glycines Ichninohe) are major pests of the soybean (Glycine max [L.] Merr.). Substantial progress has been made in identifying the genetic basis of limiting these pests in both model and non-model plant systems. Classical linkage mapping and genome-wide association studies (GWAS) have identified major and minor quantitative trait loci (QTLs) in soybean. Studies on interactions of SBA and SCN effectors with host proteins have identified molecular cues in various signaling pathways, including those involved in plant disease resistance and phytohormone regulations. In this paper, we review the molecular basis of soybean resistance to SBA and SCN, and we provide a synthesis of recent studies of soybean QTLs/genes that could mitigate the effects of virulent SBA and SCN populations. We also review relevant studies of aphid–nematode interactions, particularly in the soybean–SBA–SCN system.
