Aphid-transmitted viruses in vegetable crops Integrated virus disease management. The majority of viruses infecting plants are spread by insects, and aphids are the most common group of. virus vectors or carriers. All potyviruses (the largest group of plant viruses) are transmitted by aphids. Aphids are sap-sucking insects and have piercing. Abstract An isometric virus of 30 nm in diameter was isolated from mustard (Brassica juncea var. oblanceolata and B. juncea var. strumsta [B. juncea var. strumata]) showing leaf yellows or yellow mosaic by means of aphid transmission in virus was identified as beet western yellows virus (BWYV), a member of the genus Polerovirus belonging to the family Luteoviridae on the basis of.

The strain specificity of SMV transmission through seed and SMV-induced seed-coat mottling were investigated in field experiments.
A virus causing a wilt of Datura stramonium was identified as a strain of henbane mosaic virus. It causes necrotic local lesions in Nicotiana rustica, and local lesions are demonstrable in tobacco by staining with of the factors affecting its transmission by Myzus persicae (Sulz.) were studied quantitatively using these lesions.. Infective aphids differed little in their ability to Cited by: CTV is an important disease problem for U.S. citrus. There is little information available on the transmission mechanism of semi-persistent transmitted plant viruses such as CTV. If the mechanism of virus transmission can be determined then it may be possible to block or disrupt its occurrence. This proposal addresses the biology of the brown citrus aphid specifically the interaction .

Intraspecific Variation in Zucchini Yellow Mosaic Virus Transmission by Myzus persicae and the Impact of Aphid Host Plant Article in Journal of Economic Entomology (6) January Three isolates of bean yellow mosaic virus (BYMV), one from Florida (FV), one from Kentucky (KV) and one from Wisconsin (WV), were compared.
Although both the FV and KV isolates proved aphid transmissible, no transmission was obtained in parallel trials with WV. Of the three BYMV isolates tested for mechanical transmissibility, WV was more infectious than either FV or KV, regardless of whether Cited by: At Univ.

Uyemoto and R. Grogan Departments of Plant Pathology, New York State Agricultural Experiment Station, Geneva, NYand University of California, Davis, CA An isolate of Bean yellow mosaic virus (BYMV) not transmitted by aphids (NAT) was compared with the aphid-transmissible isolate (MI) from which it was derived.
For each isolate, the sequence of the coat protein and parts of the helper component was determined. A single nucleotide substitution caused a NAG to NAS alteration in the coat protein of the non aphid-transmissible by: Bean aphids transmit Beet yellows virus, Beet western yellows virus, and Beet mosaic virus.
Although bean aphids do not vector viruses as efficiently as green peach aphid, generally bean aphid occurs at higher densities, which tends to negate the differences in virus transmission efficiency. Infestations of bean aphid generally begin on young. Several aphid non-transmissible strains of zucchini yellow mosaic potyvirus (ZYMV) have been described, in relation with mutations in the two viral proteins required for transmissibility, coat protein and helper component.
Assistance mechanisms were previously shown to allow transmission of such strains when functional proteins are provided in by: 2. APHIDS Lee Townsend, Extension Entomologist Aphids are soft-bodied insects that use their piercing sucking mouthpa rts to feed on plant sap.
