Leaf Symptoms

Surveys of peanut crops in northeastern Brazil since 1995 showed the occurrence of a hitherto unreported virus disease. Characteristic leaf symptoms were ring spots and blotches. The virus was seed transmitted in peanut (1/610) and cowpea (47/796). Local and systemic symptoms were observed in cowpea (cv. TVu 3433) known to be susceptible to most Cowpea aphid-borne mosaic virus (CABMV) isolates. The virus was transmitted by aphids Toxoptera citricidus and Aphis gossypii. Using degenerate primers, the 3′ terminal region of the viral genome was cloned and sequenced. Sequence analyses of the coat protein and the 3′ untranslated region indicated that the potyvirus was most closely related to CABMV isolates from South Africa, Zimbabwe, and the United States. On the basis of genome analysis, the virus was identified as CABMV. The natural occurrence of CABMV on peanut has so far not been reported. The significance of this finding especially for germ plasm exchange is discussed.

Cowpea aphid-borne mosaic virus (CABMV) is a potyvirus that causes the most serious virus disease of passion fruit crops in Brazil. It is transmitted by several species of aphids in a non-persistent, non-circulative manner. The reaction of 16 species of Passiflora to infection by mechanical inoculation with four Brazilian isolates of CABMV was evaluated under greenhouse conditions. Only P. suberosa, a wild species, was resistant to infection by all virus isolates, in two independent assays. P. suberosa grafted onto infected P. edulis f. flavicarpa did not develop symptoms; neither was the virus detected by RT-PCR in the upper leaves, suggesting that this species is immune to CABMV.

Background: Whitefly is one of the most destructive sucking pest in the tropical and subtropical regions of the world and causing significant crop losses directly by sucking sap from the plants and indirectly through the transmission of viral diseases specifically caused by the genus Begomovirus. The Begomovirus species viz., Mungbean yellow mosaic India virus (MYMIV) and Mungbean yellow mosaic virus (MYMV) are causing yellow mosaic virus disease in soybean, which is transmitted by whiteflies. The disease accounts to 30-70 per cent yield loss and increases up to 80 - 100 per cent during severe incidence. Hence, there is a need for development of integrated pest management strategies against disease and whiteflies, for this the knowledge on virus-vector relationship is required. But, the studies on biological relationship of yellow mosaic virus disease and whitefly in soybean are scarce. At this juncture, considering the importance of disease in soybean, the present investigation was carried out to know the virus -vector relationship of the YMV and whitefly in soybean.Methods: The experiment on virus-vector relationship of yellow mosaic virus and whitefly in soybean was conducted at Department of Entomology, College of Agriculture, G. B. Pant University of Agriculture and Technology, Pantnagar, Uttarakhand during 2016-17. The data on number of whiteflies per plant, acquisition and inoculation access feeding period and pre and post starvation period required for effective transmission of virus was recorded.Result: A single viruliferous whitefly was able to transmit virus and ten viruliferous whiteflies per plant were required for cent per cent transmission of virus. The minimum acquisition access and inoculation access feeding periods required for virus transmission was 0.25h (15 min) each; while the 100 per cent virus transmission was recorded with acquisition and inoculation period of 12h, each. The per cent transmission was increased with the increase of acquisition and inoculation periods. The rate of transmission was positively correlated with pre-acquisition starvation period and negatively correlated with post- acquisition starvation period.
