“…However, the main damage caused by WCM extends from its ability to transmit and spread multiple damaging viruses to a range of cereal crops (Oldfield and Proeseler 1996). At least four viruses have been reported as being transmitted by WCM: Wheat streak mosaic virus (WSMV) (Slykhuis 1955), Wheat mosaic virus (WMoV) (formerly known as High plains virus [HPV]) (Hadi et al 2011;Jensen and Lane 1994;Jensen et al 1996;Seifers et al 1997;Skare et al 2006), Brome streak mosaic virus (BrSMV) and Triticum mosaic virus (TriMV) (Seifers et al 2008(Seifers et al , 2009.…”

The wheat curl mite (WCM), Aceria tosichella, and the plant viruses it transmits represent an invasive mite-virus complex that has affected cereal crops worldwide. The main damage caused by WCM comes from its ability to transmit and spread multiple damaging viruses to cereal crops, with Wheat streak mosaic virus (WSMV) and Wheat mosaic virus (WMoV) being the most important. Although WCM and transmitted viruses have been of concern to cereal growers and researchers for at least six decades, they continue to represent a challenge. In older affected areas, for example in North America, this mite-virus complex still has significant economic impact. In Australia and South America, where this problem has only emerged in the last decade, it represents a new threat to winter cereal production. The difficulties encountered in making progress towards managing WCM and its transmitted viruses stem from the complexity of the pathosystem. The most effective methods for minimizing losses from WCM transmitted viruses in cereal crops have previously focused on cultural and plant resistance methods. This paper brings together information on biological and ecological aspects of WCM, including its taxonomic status, occurrence, host plant range, damage symptoms and economic impact. Information about the main viruses transmitted by WCM is also included and the epidemiological relationships involved in this vectored complex of viruses are also addressed. Management strategies that have been directed at this mite-virus complex are presented, including plant resistance, its history, difficulties and advances. Current research perspectives to address this invasive mite-virus complex and minimize cereal crop losses worldwide are also discussed.

“…It is transmitted by the wheat curl mite (WCM, Aceria tosichella Keifer). The virus is widely distributed in most wheat‐growing regions of the world, including the USA, Canada, Mexico, Brazil, Argentina, Europe, Turkey, Iran, Australia and New Zealand (Hadi et al ., ; Navia et al ., ).…”

Wheat streak mosaic virus (WSMV) causes wheat streak mosaic, a disease of cereals and grasses that threatens wheat production worldwide. It is a monopartite, positive-sense, single-stranded RNA virus and the type member of the genus Tritimovirus in the family Potyviridae. The only known vector is the wheat curl mite (WCM, Aceria tosichella), recently identified as a species complex of biotypes differing in virus transmission. Low rates of seed transmission have been reported. Infected plants are stunted and have a yellow mosaic of parallel discontinuous streaks on the leaves. In the autumn, WCMs move from WSMV-infected volunteer wheat and other grass hosts to newly emerged wheat and transmit the virus which survives the winter within the plant, and the mites survive as eggs, larvae, nymphs or adults in the crown and leaf sheaths. In the spring/summer, the mites move from the maturing wheat crop to volunteer wheat and other grass hosts and transmit WSMV, and onto newly emerged wheat in the fall to which they transmit the virus, completing the disease cycle. WSMV detection is by enzyme-linked immunosorbent assay (ELISA), reverse transcription-polymerase chain reaction (RT-PCR) or quantitative RT-PCR (RT-qPCR). Three types of WSMV are recognized: A (Mexico), B (Europe, Russia, Asia) and D (USA, Argentina, Brazil, Australia, Turkey, Canada). Resistance genes Wsm1, Wsm2 and Wsm3 have been identified. The most effective, Wsm2, has been introduced into several wheat cultivars. Mitigation of losses caused by WSMV will require enhanced knowledge of the biology of WCM biotypes and WSMV, new or improved virus detection techniques, the development of resistance through traditional and molecular breeding, and the adaptation of cultural management tactics to account for climate change.

“…WSMV can cause significant damage to spring and winter wheat. Outbreaks of WSMV have great potential for destruction in wheat crops, causing yield losses approaching 100% (Christian, Willis, 1993;French, Stenger, 2002;Hadi et al, 2011). The virus is transmitted from infected to healthy wheat plants by the wheat leaf curl mite Aceria tosichella Keifer (Slykhuis, 1955;French, Stenger, 2002;Navia et al, 2013), and low rates of seed transmission have been reported (Jones et al, 2005;Lanoiselet et al, 2008).…”

Wheat streak mosaic virus (WSMV) causing viral diseases in graminaceous plants worldwide has been isolated in Lithuania from natural infected winter wheat (Triticum aestivum L.) plants. The diseased wheat plants with pronounced symptoms (chlorotic mottling, streaks of leaves and stunting) were found in various localities of Vilnius and Kaunas regions. Virus isolates were investigated by serology, electron microscopy (EM) and reverse transcription-polymerase chain reaction (RT-PCR) methods. The identification of the virus was based on the results of symptomology on host-plants, positive DAS-ELISA (double-antibody sandwich enzyme-linked immunosorbent assay) test, particle morphology (presence of flexuous, filamentous virus particles ~15 nm in diameter and 700 nm in length) and a specific amplification fragment size (750 bp) of virus RNA (ribonucleic acid) in RT-PCR. Isolate (WSMV-1313) of WSMV from wheat plants was characterized by a coat protein gene sequence analysis.Comparison with other WSMV isolates from the GenBank database showed that the Lithuanian WSMV isolate shares the highest sequence similarity to WSMV isolates from Russia (98.3%) and Italy (98.1%). This is the first report of wheat as a natural host for WSMV in Lithuania.
