Abstract:

The study was conducted at Department of Plant Pathology, Bangladesh Agricultural University, Mymensingh to find out virus-vector relationship in JLMV of jute during 2010-2011. So far, 12 different diseases have been recorded on jute in Bangladesh. Among these diseases jute leaf mosaic is considered as the most devastating one. The minimum acquisition feeding period of 30 min was required for whitefly on a JLMV source that resulted in 12.5% transmission and for cent percent transmission 48 h AFP was required. A minimum feeding period of 15 min was required by a viruliferous whitefly to cause infection on jute test plants; this gave 10% transmission. With inoculation access of 48 h on jute test plants, the transmission rose to 100%. Starving the vector for 30 min and 5 h pre-acquisition resulted 10 and 100% transmission of JLMV respectively. Extending the fasting period beyond 5 h resulted in a reduced transmission level. Starving the vector for 30 min and 4 h post-acquisition resulted 30 and 95% transmission of JLMV, respectively. Extending the fasting period beyond 4 h resulted in a reduced transmission level. Higher transmission rates were obtained when the younger leaves on tomato plants were used for acquisition and inoculation. The young seedlings up to the age of 20 days were found to be highly vulnerable to the virus.
