“…Additional losses have been incurred since then, primarily in Colorado and parts of neighboring states including northeastern New Mexico, southwestern Nebraska, and western Kansas (Berzonsky et al, 2002). Various management approaches have proven effective in alleviating damage from D. noxia (Quisenberry and Peairs, 1998) and natural biological controls have continued to evolve (Noma et al, 2005). Considerable loss reduction has been attributed to the widespread adoption of D. noxia ‐resistant cultivars by producers of winter wheat in areas with frequent D. noxia infestations (Berzonsky et al, 2002).…”

Virulence of Two Russian Wheat Aphid Biotypes to Eight Wheat Cultivars at Two Temperatures

et al. 2006

Biotype 2 of the Russian wheat aphid, Diuraphis noxia (Mordvilko), is virulent to both sources of resistance presently available in commercial wheat, Triticum aestivum L. The performance of biotype 2 was compared with that of biotype 1 on eight wheat cultivars at two constant temperatures, and the plants were evaluated for overall damage and leaf rolling. Colonies of biotype 2 grew an average of 2.3 and 24.9 times faster in the first and second generation, respectively, than did their biotype 1 counterparts at 20°C, reaching 80 to 125 aphids per plant after 20 d, compared with 10 to 31. The no. of aphids per plant at 10 and 20 d after infestation displayed a significant biotype–temperature interaction. There was also a biotype–temperature interaction for plant damage at 10 d, and for damage and leaf rolling at 30 d. After 20 d at 24°C, damage ratings ranged from 7.3 to 8.6 on a scale of 1.0 to 9.0, and leaf rolling ranged from 2.4 to 2.9 on a scale of 1.0 to 3.0 for biotype 2, whereas values for biotype 1 ranged from 2.8 to 5.1 and 1.4 to 2.2, respectively. There were no differences among cultivars in plant damage or leaf rolling induced by biotype 2, and ratings of both were higher than for biotype 1 in all cultivar–temperature combinations. Biotype 2 D. noxia has overcome both Dn4‐ and Dny‐based sources of resistance, was more virulent than biotype 1 to all the cultivars tested, and induced plant injury more rapidly than biotype 1, especially at higher temperatures.

“…In response to the agricultural impact of this invasion, D. noxia became the target of possibly the largest classical biological control program ever conducted in North America. However, the ultimate demise of D. noxia as the key pest of wheat in the region in the mid-1990s corresponded with the release of wheat cultivars resistant to the aphid in conjunction with the gradual establishment of biological control by a complex of native generalist predators, primarily Coccinellidae and Syrphidae (Nechols and Harvey 1998, Michels et al 2001, Bosque-Perez et al 2002, Noma et al 2005. Similarly, in European regions syrphids and coccinellids are reported to comprise Ͼ90% of associated beneÞcial organisms contributing to D. noxia control (Farkas and Kozma 2003).…”

In spring 2003, several outbreaks of the Russian wheat aphid, Diuraphis noxia (Mordvilko), were reported in fields of supposedly resistant wheat cultivars ('Stanton', 'Halt', and 'Prairie Red') in eastern Colorado. We conducted two laboratory experiments to compare the biological performance of this new biotype 2 (B2) to that of two D. noxia collections of biotype 1 (B1) from western Kansas by using three wheat cultivars as host plants: 'Trego', a susceptible cultivar, and Stanton and Halt, two cultivars with different genetic sources of resistance. Survival of solitary nymphs from first instar to adult for the two clones of B1 on Trego was 96 and 90%, respectively, compared with 67 and 43% on Stanton, and 65 and 57% on Halt. In contrast, B2 had 60% survival on Trego, 43% survival on Halt, and 85% survival on Stanton. One clone of B1 required longer to mature on Halt compared with Trego or Stanton, but no other differences in developmental time among cultivars were significant. The standardized fecundity of solitary foundresses of the B1 clones was 19.6 and 20.1 nymphs on Trego, compared with 4.6 and 0.9 on Stanton, and 2.8 and 1.1 on Halt, respectively, over the same period. In contrast, fecundity of B2 was 21.1, 20.8, and 19.7 on Trego, Stanton, and Halt, respectively. When larger colonies developed on individual plants over longer periods, Trego supported the largest number of B1 aphids by experiment's end, whereas Stanton and Halt yielded the largest numbers of B2. The order of overall plant damage was Trego > Stanton > Halt when infested with B1, with no significant differences for B2. Trego had more pronounced leaf rolling than other cultivars, independent of biotype. Collectively, the results suggest that D. noxia B2 from Colorado has evolved cross-virulence to both Dn4- and Dny-based resistance sources.

Biology, ecology and management of Diuraphis noxia (Hemiptera: Aphididae) in Australia

et al. 2020

The Russian wheat aphid, Diuraphis noxia (Mordvilko ex Kurdjumov), is one of the world's most economically important pests of grain crops and has been recorded from at least 140 grass species within Poaceae. It has rapidly dispersed from its native origin of Central Asia into most major grain-producing regions of the world including Africa, Asia, Europe, the Middle East, North America and South America. Diuraphis noxia was first found in Australia in a wheat crop in the mid-north of South Australia in May 2016. Since then, D. noxia has been recorded throughout grain-growing regions of South Australia, Victoria, New South Wales and Tasmania. The distribution will continue to expand, with climatic suitability modelling suggesting D. noxia can persist in all key grain regions, including large parts of Western Australia and Queensland. Australian populations of D. noxia appear to be anholocyclic, with no sexual stages being observed. The aphids can reproduce year round as long as host plants are available. Australian farmers have generally adopted prophylactic insecticide seed treatments and/or foliar sprays to manage D. noxia. Research is required to fully understand yield impacts, host preferences and host plant resistance associated with D. noxia. Cultural control through managing alternate host plants over summer, agronomic crop management, biological control and developments in host plant resistance should provide considerable future benefits. Key wordsexotic pest, invasion, management, review, Russian wheat aphid. DESCRIPTIONOriginally named Brachycolus noxius, the Russian wheat aphid (now known as Diuraphis noxia) was first recognised as a separate species by Mordvilko in a paper by Kurdjumov (1913). Detailed descriptions of D. noxia have been provided by Blackman and Eastop (1984) and Stoetzel (1987). In brief, D. noxia has an elongated, spindle-shaped body, with the tips of the legs and distal third of the (distinctively short) antennae black. The wings *pumina@unimelb.edu.au
