Abstract:
An investigation was made to establish the virus-vector relationship for which transmission of sunflower necrosis virus through Thrips palmi (Karny) was carried out. The transmission of sunflower necrosis virus by thrips ranged from 13.33 to 23.33 per cent in the genotype tested and all genotype showed positive for DAC ELISA test. Further, results also revealed that vector Thrips palmi (Karny) could acquire the virus with an Acquisition Access Period (AAP) of 3 days from infected sunflower plants with 13.33 % transmission. Similarly, Inoculation Access Period (IAP) of 6 days was required for successful transmission of virus with 16.67 % transmission of virus. The percent transmission increased with increase in both acquisition and inoculation feeding period. Further, two thrips enough to acquire and transmit the virus from infected to healthy sunflower plant.
