The results revealed that an incidence ranging from 0.00 to 7.72 nymph per plant at Honnavile, Shimoga taluk, 0.00 to 7.25 at SRDC, MPM, Bhadravathi taluk and 0.00 to 13.9 at Kathalagere, Davanagere district. The high incidences of 7.72, 7.25 and 13.9 nymph per plant were observed during September, June and August months, respectively. The lowest incidence of 0.00 nymph per plant was observed during November to February months at Honnavile and Karehalli and December to January in Kathalagere respectively, due to rainfall received during that period in all the locations.
