About aphid species tested to date as vectors of plant viruses represent only about 9% of the known species. Oil-induced inhibition of the transmission of bean yellow mosaic virus by Acyrtosiphon onobrychis and of beet yellows virus by Aphis fabae showed that oil inhibits the transmission of viruses by several species of aphid vector.

Aphids transmitted bean yellow mosaic virus (BYMV) more frequently to bean plants maintained at 18for 2 days before inocula- tion than to those maintained at 27(Swen- son and Sohi, ).

Effect of postinoculation temperature on numbers of local lesions obtained by sap inoculation varies among different viruses (Kassanis, ]).Cited by: 4. Experiments were done to determine the effect of some factors on the level of transmission of bean yellow mosaic virus (BYMV) by aphids.

The effect of different source plant treatments, the effect of light on test plant susceptibility, and the effect of a second virus on the transmission of BYMV were opalsdz.com by: 1.

Jun 01,  · Abstract. Reproduction and colonizing behavior of pea aphids, Acyrthosiphon pisum (Harris), were studied on reproductive arrowleaf clover, Trifolium vesiculosum Savi, using four treatments: healthy, infected with bean yellow mosaic virus (BYMV), infected with a Phytophthora sp.

Reproduction of aphids in no-choice Cited by: THE TRANSMISSION OF BEAN YELLOW MOSAIC VIRUS BY SOME STRAINS OF TILE APHID, MYZUS PERSICAE (SuLzER) INTRODUCTION The factors which influence the tranemisslon rate of' plant viruses by their insect vectors have been studied for about 25 years.

Numerous factors have been discover- ed. One of these is opalsdz.comion in the virus- transmitting ability of the vectors.

Yellow dwarf viruses belong to the family Luteoviridae, characterised by a circulative (nonpropogative) mode of virus transmission, where virons circulate in the vector's body, in a persistent.

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 The role played by seed transmission in the evolution and epidemiology of viral crop pathogens remains unclear.

We determined the seed infection and vertical transmission rates of zucchini yellow mosaic virus (ZYMV), in addition to undertaking Illumina sequencing of nine vertically transmitted ZYMV opalsdz.com by: Fleischer, S. Transmission efficiency of Cucumber mosaic virus by aphids associated with virus epidemics in snap bean.

Author information: (1)Department of Plant Pathology, Pennsylvania State University, Cited by: AG Temperate Pulse Viruses: Bean Yellow Mosaic Virus (BYMV)Bean yellow mosaic virus (BYMV) was first reported on French beans from the USA and the Netherlands in and is now distributed worldwide.

It has a wide host range which includes the temperate pulses and pasture legumes, tropical legumes and ornamental hosts. The virus is spread by a number of aphid species non-persistently as. The effect of temperature, relative humidity (RH) and light on aphid transmission of potato virus Y (PVY) and potato leafroll virus (PLRV) was studied using as vectorsMyzus persicae Sulz.

Host susceptibility was enhanced by 48 h pre-inoculation exposure at 25°C and by 48 h post-inoculation exposure to 30°opalsdz.com by: May 10,  · Aphids as Virus Vectors focuses on aphids as vectors of plant viruses and the fundamentals of their relationship with virus and host.

Sep 01,  · 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 isolate. Cited by: Aphids And viruses in puLse CrOps fACt sheet integrated control of aphids is required to minimise the virus risk in pulses Aphids can damage crops by spreading viruses or causing direct damage when feeding on plants.

feeding damage generally requires large.

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.

is a mode of transmission that is characterized with a short time of acquisition, inoculation. California, Raabe et al.

() note that for Cymbidium and other orchids only Bar mottle virus was transmitted by aphids, the green peach aphid. Nevertheless, aphid transmission of cucumber mosaic, turnip mosaic, and bean yellow mosaic, and other viruses to orchids should be a concern to breeders and production growers. Transmitted in a non-persistent manner by aphids after brief acquisition and feeding probes; retained on stylet tips only.

Transmitted by sap or by contacting infected plant parts. Some can be transmitted through seed by infecting the seed embryo. ARTHROPODS IN RELATION TO PLANT DISEASE Attributes of Bean Yellow Mosaic Potyvirus Transmission from Clover to Snap Beans by Four Species of Aphids (Homoptera: Aphididae) R.

The black bean aphid is a major pest of sugar beet, bean, and celery crops, with large numbers of aphids cause stunting of the plants. Beans suffer damage to flowers and pods which may not develop properly. Early-sown crops may avoid significant damage if they have already flowered before the number of aphids builds up in the opalsdz.com: Insecta.

Dec 01,  · Read "Assessing aphids potato virus Y-transmission efficiency: A new approach, Journal of Virological Methods" on DeepDyve, the largest online rental service for scholarly research with thousands of academic publications available at your fingertips. Black bean aphids are usually visible on plants because of their contrasting color.

Aphids feed by sucking plant juices, so infested growth is often yellowed and curled. In addition to the direct damage aphid feeding does to plants, aphids can transmit several diseases. Preventing Problems: Check plants often for early outbreaks.
