Abstract In an investigation carried out at Regional Coconut Research Station, Bhatye, Ratnagiri (M.S.) during 2018-19 and 2019-20 to validate the effect of coloured traps (red, yellow, green, black and white) in attracting rugose spiralling whitefly (RSW), the yellow coloured sticky traps, made with sheets (100 x 50 cm) and smeared with white grease recorded the maximum catch of rugose spiraling whiteflies (44.2) and was significantly superior over black and white colour sticky traps but was on par with green (26.6 nos.) and red coloured sticky traps (11.4 nos.). The black and white coloured sticky traps trapped the minimum of 1.9 and 6.4 rugose spiraling whiteflies at five different points of dimensions of 5 cm2, respectively.
