Aphid transmission of nanoviruses [PDF]

open access: yesArchives of Insect Biochemistry and Physiology, 2020
AbstractThe genus Nanovirus consists of plant viruses that predominantly infect legumes leading to devastating crop losses. Nanoviruses are transmitted by various aphid species. The transmission occurs in a circulative nonpropagative manner. It was long suspected that a virus‐encoded helper factor would be needed for successful transmission by aphids ...

Bees and Aphides [PDF]

open access: yesNature, 1873
IN his interesting communication respecting the relations supposed to exist between Trigona and Membracis, Dr. H. Muller appears to have overlooked the Abbe Boisier's observation (Kirby and Spence, “Introduction to Entomology,” 7th edition, p. 384) that hive-bees will collect the honey-dew excreted by Aphides.
