Different colour sticky traps are commonly used for monitoring the population of many sucking pests such as thrips, whiteflies, leaf miner adults and aphids. They have also been used to monitor the natural enemies associated with the sucking pests. Presently, the monitoring the incidence of sucking pests in pomegranate using sticky traps is wanting. Hence, the study was conducted in pomegranate planting at orchard of Tamil Nadu Agricultural University, Coimbatore during 2016, using different colour laden sticky traps like yellow, pale yellow, green, orange and red. The traps were placed at five different locations and every week, the location of trap is changed and the attraction of aphids, thrips, whiteflies and coccinellids to traps is recorded. Green was the most attracted colour for aphids (208.4 aphid adults /per trap/per week) followed by yellow (202.6 aphid adults /per trap/per week) and pale yellow. While yellow was most attractive for thrips (177.4 thrips/per trap/per week) and white fly (22.1 whiteflies /per trap/per week) followed by pale yellow (122.1 thrips/per trap/per week) & (13.8 whiteflies/per trap/per week) and green (110.9 thrips/per trap/per week) & (13.1 whiteflies/per trap/per week) respectively. Most insect predators like lady bird beetles, minute pirate bugs, parasitic wasps and honey bees also exhibited preferences to particular trap colour characteristics, whereas green lacewings and spiders showed no such preference.
