Transmission studies of leaf crinkle virus in blackgram (Vigna mungo L.)

Blackgram (Vigna mungo) is a major pulse crop grown in Tamil Nadu and leaf crinkle virus is an important disease that infects the crops at various stages of its growth, which reduce the yield drastically. There are conflicting reports on the transmission of ULCV by insects that includes aphids, leafhopper, whitefly and beetle. Hence, a study was carried out to identify the putative vectors involved in the transmission of the disease. Found that the virus was effectively transmitted by aphid vector, Aphis craccivora in a non-persistent manner and whitefly (Bemisia tabaci). No transmission was observed by melon aphid (Aphis gossypii), cabbage aphid (Brevicoryne brassicae) and hadda beetles (Epilachna vignitioctopuntata and Epilacna dodecastigma). | Transmission studies of leaf crinkle virus in blackgram Vigna mungo L.
