AbstractField experiments were carried out to determine the capture and attractiveness of different colour sticky traps (yellow, blue, green and white installed at varying heights of 25, 50 and 75 cm) and pheromone traps in monitoring the occurrence of diamondback moth (Plutella xylostella L.) in cabbage fields. Yellow sticky trap placed at 25 cm provided the best result with significantly more DBM (13 moths) catch than other combinations. The study also revealed that the addition of synthetic lure increased trapping efficiency. Also, yellow pheromone trap with lure recorded the highest DBM count. Given the capacity of DBM to develop resistance against insecticides, these findings may contribute in designing effective IPM strategies.
