“…In the absence of cultivated wheat outside of the wheat-growing season, populations of Russian wheat aphid colonies can be supported by various other plant species alternate to wheat. In their study on alternate hosts of the Russian wheat aphid, Kindler and Springer (1989) found that 47 of 48 cool-season grasses and 18 of 32 warm-season grasses could serve as hosts for the Russian wheat aphid, while Weiland et al (2009) found that Russian wheat aphid host range includes wild grasses including Agropyron, Bromus, Elymus Thinopyrum, and Pascopyrum. Armstrong et al (1991) found Russian wheat aphid on 20 of 25 species of grasses in Colorado.…”

The incidence and host associations of Russian wheat aphid were investigated in the wheat-growing areas of South Africa from 2009 to 2011. Most Russian wheat aphid samples were collected on dryland wheat, while few samples were collected on irrigation wheat. Volunteer wheat and rescue grass were the preferred alternative host plants to cultivated wheat for all three biotypes. No RWASA1 samples were collected from oats, but RWASA2 seemed to be able to survive successfully on oats, with 12.26% of the total RWASA2 samples collected on oats and 2.83% RWASA2 samples on wild oats. The intrinsic rate of population increase (rm) has often been used as an index of herbivore performance, and alternative host suitability can be quantified using growth rate parameters, such as the intrinsic rate of increase. The rm was determined for the three South African biotypes-RWASA1, RWASA2, and RWASA3--on seven different host plants. Russian wheat aphid biotypes showed a positive intrinsic rate of increase on all host plants tested, indicating that these host plants were all suitable hosts to support populations of all three biotypes. The rm on TugelaDn, which is resistant to RWASA1 but susceptible to RWASA2 and RWASA3, was significantly higher for RWASA3 and lowest for RWASA1. The rm for RWASA2 and RWASA3 was significantly lower on TugelaDn5, which is resistant to these two biotypes. The rm for RWASA2 and RWASA3 was significantly higher than for RWASA1 on both oats and wild oats. Aphid infestation of winter wheat in the spring may be directly influenced by their success and abundance in noncultivated host plants between harvest and emergence of the cultivated wheat. Therefore, it is important to consider the success of different Russian wheat aphid biotypes on host plant alternatives to cultivated cereals when planning a management strategy for Russian wheat aphid in an area.

“…Diuraphis noxia can disperse not only over short distances by migrations, but also over long distances through international trade of crops, such as wheat, barley, rye, and oats [ 71 , 72 , 73 , 74 ]. Therefore, in the future climatic scenario, these countries with increased potential suitable areas, particularly, the UK, Russia, Canada, Sweden, and France, which showed a relatively large area of increase, should be alert to the import of the host plants and strengthen the warning and management system to prevent secondary invasion.…”

Invasive crop pests (ICPs) are a major cause of crop losses and adversely affect global food security. Diuraphis noxia Kurdjumov is a significant ICP that feeds on the sap of crops, reducing crop yield and quality. Although estimating the geographical distribution patterns of D. noxia under climate change is critical for its management and global food security, such information remains unclear. Based on 533 global occurrence records and 9 bioclimatic variables, an optimized MaxEnt model was used to predict the potential global geographical distribution of D. noxia. The results showed that Bio1, Bio2, Bio7, and Bio12 were significant bioclimatic variables that influenced the potential geographical distribution of D. noxia. Under current climatic conditions, D. noxia was mainly distributed in west-central Asia, most of Europe, central North America, southern South America, southern and northern Africa, and southern Oceania. Under the SSP 1-2.6, SSP 2-4.5, and SSP 5-8.5 scenarios for the 2030s and 2050s, the potential suitable areas increased, and the centroid migrated to higher latitudes. The early warning of D. noxia in northwestern Asia, western Europe, and North America should be attended to further. Our results provide a theoretical basis for early monitoring and warning of D. noxia worldwide.
