Abstract

A field trial was conducted to evaluate the effectiveness of different coloured sticky traps against sucking pests of Bhut Jolokia during October to April 2013–14 and 2014–15, respectively. In the first season, seven coloured sticky traps viz., Violet, Red, Yellow, Orange, Green, Blue and White (Control) were used during 2013–14 and the most effective trap was placed at seven different heights (at the plant canopy level, 10, 20, 30, 40, 50 and 60 cm height) during 2014–15. Results indicated that the maximum number of sucking pests viz., Aphis gossypii Glover, Scirtothrips dorsalis Hood, Bemisia tabaci Gennadius and Leafhopper, Amrasca biguttula biguttula Ishida was attracted to yellow sticky traps with a mean population of 132.0, 60.5, 34.4 and 8.3 per trap, respectively. The highest numbers of sucking pests were observed to record at yellow sticky traps placed at the plant canopy level with a population of 126.9 aphids, 49.4 thrips, 23.6 leafhoppers and 7.0 whiteflies per trap followed by traps placed at 10 and 20 cm height above canopy level.
