“…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.

“…The variation among temperatures used for these experiments could be a possible explanation for the differences in results. Furthermore, there may be interactions between abiotic factors, like temperature, on the impact of Rag genes [ 37 , 38 ]. However, the extent that the protection from all Rag genes is influenced by temperature is unknown [ 39 ].…”

Reduced Fitness of Virulent Aphis glycines (Hemiptera: Aphididae) Biotypes May Influence the Longevity of Resistance Genes in Soybean

Sustainable use of insect resistance in crops require insect resistance management plans that may include a refuge to limit the spread of virulence to this resistance. However, without a loss of fitness associated with virulence, a refuge may not prevent virulence from becoming fixed within a population of parthenogenetically reproducing insects like aphids. Aphid-resistance in soybeans (i.e., Rag genes) prevent outbreaks of soybean aphid (Aphis glycines), yet four biotypes defined by their capacity to survive on aphid-resistant soybeans (e.g., biotype-2 survives on Rag1 soybean) are found in North America. Although fitness costs are reported for biotype-3 on aphid susceptible and Rag1 soybean, it is not clear if virulence to aphid resistance in general is associated with a decrease in fitness on aphid susceptible soybeans. In laboratory assays, we measured fitness costs for biotype 2, 3 and 4 on an aphid-susceptible soybean cultivar. In addition, we also observed negative cross-resistance for biotype-2 on Rag3, and biotype-3 on Rag1 soybean. We utilized a simple deterministic, single-locus, four compartment genetic model to account for the impact of these findings on the frequency of virulence alleles. When a refuge of aphid susceptible was included within this model, fitness costs and negative cross-resistance delayed the increase of virulence alleles when virulence was inherited recessively or additively. If virulence were inherited additively, fitness costs decreased the frequency of virulence. Combined, these results suggest that a refuge may prevent virulent A. glycines biotypes from overcoming Rag genes if this aphid-resistance were used commercially in North America.

“…Because of its economic importance and recent introduction to North America, most studies on A. glycines have focused on documenting the biology and genetics of this species in the USA (Kim et al 2008;Michel et al 2009;Richardson 2012;Jun et al 2013;Swenson et al 2014). Recently, much effort has been made to identify the origin of invasive populations in North America, but these have been largely based on limited samples.…”

Biological invasion is considered among the most important global environmental problems. Knowledge of the source and dispersal routes of invasion could facilitate the eradication and control of invasive species. Soybean aphid, Aphis glycines, is among the most destructive soybean pests. For effective management of this pest, we conducted genetic analyses and approximate Bayesian computation analysis to determine the origins and dispersal of the aphid species, as well as the source of its invasion in the USA, using 8 microsatellite loci and the mitochondrial cytochrome c oxidase subunit I gene. We were able to identify a significant isolation by distance pattern and 3 genetic lineages in the microsatellite data but not in the mtDNA dataset. The genetic structure showed that the USA population had the closest relationship with those from Korea and Japan, indicating that the 2 latter populations might be the sources of the invasion to the USA. Both population genetic analyses and approximate Bayesian computation showed that the northeastern populations in China were the possible sources of the further spread of A. glycines to Indonesia. The dispersal history of this aphid can provide useful information for pest management strategies and can further help predict areas at risk of invasion.
