The Screening of tomato cultivars (hybrids/ varieties) for whiteflies in field condition was carried out during 2012-13. All the experimental studies were conducted at Main Agriculture Research Station Raichur Karnataka. The results revealed that, 15 Days after transplanting Vybhav recorded least number of adult (1.00/ three leaves) followed by Arka Samrat, PTR 4 was significantly preferred variety with highest (4.50) number of adult whitefly population. 30 Days after transplanting the variety Vybhav maintained its superiority over other cultivars (hybrids/varieties) with significantly least (1.25) number of adult whitefly per three leaves. Adult whitefly preference was more on PTR 6 and PTR 4 and least preference was observed in Vybhav, Arka Samrat, Arka Rakshaka and Arka Ananya. 45 Days after transplanting wherein Vybhav recorded least (1.50/ three leaves) adult whitefly population followed by Arka Samrat and Arka Rakshaka which recorded 3.25 and 3.50 adult whitefly per three leaves respectively. PTR 4, PTR 6 and Arka Ananya, recorded 6.25, 6.00 and 4.00 adult whitefly per three leaves respectively. Vybhav variety recorded least per cent ToLCV disease incidence (7.79%) whereas, Arka Samrat, Arka Rakshaka and Arka Ananya recorded 14.98, 18.57 and 20.7 per cent disease incidence respectively and were on par with each other. PTR 4 and PTR 6 recorded the maximum per cent disease incidence of 27.14 and 28.58 per cent respectively and were on par with each other.
