Abstract: In order to study the epidemiology of bud necrosis disease of tomato caused by peanut bud necrosis virus (PBNV) in Raichur district of karnataka, the experiment was conducted at MARS, UAS, Raichur during Kharif 2014-15. During the study variation of PBND incidence in tomato in relation to thrips vector population and climatic factor was correlated. Relationship between the thrips population and maximum temperature showed, there exist a zero correlation between the thrips population and maximum temperature with a correlation coefficient (r) of 0.00. Relationship between the thrips population and rainfall showed that a slight negative correlation exists between the thrips population and rainfall with a correlation coefficient (r) of – 1.04. Relationship between the thrips population and relative humidity indicate that there is very low correlation exists between the thrips population and relative humidity. Relationship between the Bud necrosis disease incidence with maximum temperature, rainfall, and relative humidity indicated that there is a very low positive correlation or almost the disease is unaffected by the weather parameters. Relationship between the Bud necrosis disease incidence with average thrips population per plant showed that there is a high positive correlation exists between the bud necrosis disease incidence and the thrips population with the correlation coefficient of 0.92.
