 ABSTRACT

Thrips infestation and WBNV disease incidence in major watermelon growing regions of Karnataka ranged from 2.02 to 4.94 and 75.44 to 92.08 per cent, respectively. Among the different localities surveyed, the watermelon fields from Bagalkot, Belgaum and Kolar district recorded relatively higher level of mean number thrips per plant and per cent WBNV disease incidence (4.94±0.24 and 92.08, 3.80±0.20 and 79.28 and 4.76±0.22 and 91.68, respectively). However, the lowest mean number of thrips per plant and per cent WBNV disease incidence (2.02±0.16 and 75.44%, respectively) was recorded from the fields of Mysore district.

Key words:  Thrips infestation, Watermelon budnecrosis virus, Tospovirus
