“…An exception to this decrease may occur, if low aphid populations are accompanied with BYDV infection. Aphid ability to vector BYDV to wheat is their greatest danger to yield loss (Zwiener et al 2005). For example, prophylactic use of seed treatment has effectively limited aphid colonization and spread of BYDV, which on some occasions resulted in economic benefits to grain production (Wilde et al 2001;Royer et al 2005).…”

Producers in the Mid-Atlantic region of the United States often use prophylactic pesticide sprays in their fields to increase wheat (Triticum aestivum L.) yields regardless of disease or insect pest levels. This study was carried out at two sites during each of two field seasons to evaluate th-e effects of pesticide applications (fungicides and insecticide) on insect abundance, beneficial arthropods, foliar damage and grain yield in winter wheat. Insecticide applications reduced densities of cereal leaf beetle (CLB) and CLB damage of flag leaves at the Queenstown and aphid at the Upper Marlboro study site compared to controls during 2009 and 2011 field seasons, respectively. However, insecticide application also reduced arthropod predators at Queenstown in 2009. Fungicide applications reduced leaf spot severity symptoms at Queenstown in 2009 and both sites in 2011. Grain yield was negatively correlated with the percentage of severely damaged flag leaves during the 2009 growing season when diseases and insects pressure was greatest. Nevertheless, yield increase associated with application of pesticides (fungicides) was observed only at one out of four siteÀyear combinations. Results from this study suggest that prophylactic sprays will not enhance wheat yields in the absence of high pest pressure.

“…O total de espécies de afídeos catalogadas somam 5000 espécies para todo o mundo (KELLER, 2006). Desse total, boa parte apresenta potencial como praga por afetar a produção agrícola de forma direta através de danos fisiológicos (FRANZEN et al, 2008), ou de forma indireta por meio da transmissão de vírus fitopatogênicos (GASSEN, 1984;LÚCIO-ZAVALETA et al,2001;ZWIENER et al, 2005;LAU et al, 2008). Mais de 165 espécies de pulgões ao redor do mundo foram identificadas a partir de culturas agrícolas produtoras de cereais (BLACKMAN et al, 2000).…”

“…Barley yellow dwarf viruses (BYDVs; genus Luteovirus , family Luteoviridae ), maize yellow dwarf virus (MYDV) and cereal yellow dwarf viruses (CYDVs) (genus Polerovirus , family Luteoviridae ), collectively known as yellow dwarf viruses (YDVs), are among the most economically important causal agents of disease in cereal crops (wheat, barley, oats and maize), as well as non‐crop grasses throughout the world (D'Arcy, ; Gill, ; Hesler, Riedell, Langham, & Osborne, ; Hewings & Eastman, ; McKirdy, Jones, & Nutter, ; Perry et al., ; Zwiener, Conley, Bailey, & Sweets, ). Earlier, Rochow () and Rochow and Muller () designated five strains of the viruses based on serological properties and aphid vector specificity as BYDV‐PAV, BYDV‐MAV, BYDV‐RPV, BYDV‐RMV and BYDV‐SGV in the genus Luteovirus .…”

The yellow dwarf (YD) disease complex epidemics in cultivated cereals grown in a specific period of the year mainly depend on the presence of potential reservoir alternative hosts harbouring both the viruses and the vectors over the off‐season and serve as a source of inoculum in subsequent cropping season, further spread being supported by efficient aphid vectors. As such, an extensive and intensive exploration to generate base line information on the identity and prevalence of YD viruses [barley yellow dwarf virus (BYDV)‐PAV, BYDV‐MAV and BYDV‐SGV; cereal yellow dwarf virus (CYDV)‐RPV; and maize yellow dwarf virus (MYDV)‐RMV] on wild annual and perennial grasses and forage cereals alternative hosts was conducted consecutively during 2013–2015 main‐ and short‐rainy seasons in cereals growing belts of Ethiopia. Random sampling was employed to collect the samples that were tested by the tissue blot immunoassay (TBIA) to identify the YDVs associated with the hosts using a battery of virus‐specific polyclonal antibodies. Of 13,604 samples analysed, YDVs were detected in 392 (2.9%) samples, which consisted of various wild grasses, forage cereals and three cultivated crops. YDVs were identified from at least 26 grass species and forage cereals, some of them are new records, and some are previously documented hosts. To our knowledge, this is the first report of YDV infection of Andropogon abyssinicus (FresenR.Br. ex Fresen.) (BYDV‐PAV), Avena abyssinica Hochst (BYDV‐PAV), Bromus pectinatus Thunb. (BYDV‐PAV and BYDV‐MAV), Eragrostis tef (Zuccagni) Trotter (BYDV‐PAV), Eragrostis sp. (BYDV‐PAV), Hyparrhenia anthistrioides Stapf. (BYDV‐PAV), Panicum coloratum L. (BYDV‐PAV), Polypogon monspeliensis (L.) Desf. (BYDV‐PAV), Setaria pumila (Poir.) Roem & Schult (BYDV‐PAV, BYDV‐SGV and MYDV‐RMV), Setaria australiensis (Scribn. & Merrill) Vickery (BYDV‐PAV, BYDV‐MAV and CYDV‐RPV) and Snowdenia polystachya (Fresen.) Pilg (BYDV‐PAV, BYDV‐MAV, BYDV‐SGV, CYDV‐RPV and MYDV‐RMV).
