Abstract:
Two sets of experiment were performed to study the transmission rate of Tomato Leaf Curl New Delhi Virus among different cucurbitaceous host. In first experiment six different varieties of different crop were taken as treatment. in first set of different crop maximum transmission per cent was seen in case of tomato to tomato with 68.52 per cent, followed by tomato to sponge gourd and tomato to bitter gourd with 53.81 and 45.83 per cent transmission respectively. Similarly, in second set of different variety of crop transmission per cent of tomato to tomato was maximum with 63.43 per cent followed by tomato to sponge gourd and bottle gourd with 54.89 and 44.32 per cent respectively. In first set of experiment minimum transmission percent was observed in case of tomato to pumpkin with 28.70 per cent followed by 38.82, 44.72 per cent in case of transmission from tomato to bottle gourd and cucumber. Whereas, in second set minimum percent of transmission of 33.77 in case of tomato to pumpkin followed by tomato to bitter gourd and cucumber with 42.08 and 43.58 per cent transmission respectively was observed. Correspondingly efficiency of white fly based on population were also checked with 1,3,5 and 10 number of whiteflies with 24 hrs. Acquisition feeding period on all the 6 crops and it was confirmed that a single whitefly is efficient to transmit begomovirus up to 37.2,38,43,37,33 and 41% in host crop tomato, bottle gourd, pumpkin, sponge gourd, Bitter gourd and cucumber respectively and it reaches maximum up to 100% if number of whiteflies increases more than 10.
