Efficacy of coloured sticky traps against thrips in cotton

Colour sticky traps are used in several crops for monitoring and mass trapping. This study evaluated coloured sticky traps for mass trapping of thrips Scirtothrips dorsalis (Hood), Thrips tabaci (Lindeman) and Thrips palmi (Karny) in cotton. The attractiveness of six colours viz., blue, yellow, orange, green, red and white in traps was evaluated during 2018 to 2020. Number of thrips captured in differed coloured traps was significantly different, with the blue-coloured sticky trap attracting more thrips followed by yellow. These observations reveal that blue and yellow-coloured traps can be used for monitoring and mass trapping of thrips as a component of IPM programme in cotton.
