To date, the effects of several viruses, such as Rice dwarf virus (RDV), Tomato mottle virus (ToMoV), Chrysanthemum stem necrosis virus (CSNV), TSWV and Barley yellow dwarf
virus (BYDV), on their transmission vectors have been studied (Nakasuji & Kiritani 1970; McKenzie 2002; Fiebig et al.
Tambien se evaluo la presencia de los potyvirus: virus rayado amarillo del puerro (Leek yellow stripe virus: LYSV) y virus enanismo amarillo de la cebolla (Onion yellow dwarf
virus: OYDV); los carlavirus: virus latente del shallot (Shallot latent virus: SLV) y virus latente comun del ajo (Garlic common latent virus: GCLV); y el tospovirus: virus manchado amarillo del iris (Iris yellow spot virus: IYSV).
The Ithaca researchers found the field-collected aphids consistently transmitted yellow dwarf
virus only when they carried most, if not all, of the nine key biomarker proteins.
They're Kepler-20e and f, two of five worlds closely orbiting a G8 yellow dwarf
950 light-years away and not quite as large and hot as the Sun.
I have learnt so much just by reading the first part, from all corners of the world - Iran, Congo, Yellow Dwarf

Thus an Ethiopian crossbreed barley in the 1950s saved the entire California crop from yellow dwarf

And visitors to the show this year can learn, among other things, how packs of voracious wolves can help arable farmers achieve effective control of aphids and so reduce the incidence of diseases like Barley Yellow Dwarf
For example, each year onion yellow dwarf
virus reduces garlic yields 30% to 50%, representing a serious economic loss for garlic growers around the world.
I use the barley yellow dwarf
viruses (BYDVs), which infect a broad range of grasses worldwide, as a model system for addressing questions about the outcome of direct and indirect competition between viruses.
An unusual and fiery combination mixes scarlet, red, and orange snapdragons; orange and yellow freesias; and yellow dwarf
