Recur­ring bag­worm out­break is a major prob­lem in the oil palm plan­ta­tion. The con­tin­u­ous use of chem­i­cal insec­ti­cides to con­trol bag­worm out­breaks, the lack of ben­e­fi­cial plants in the plan­ta­tion to attract nat­ural ene­mies, and infes­ta­tion in neigh­bour­ing plan­ta­tions were reported as the con­tribut­ing fac­tors for bag­worm out­breaks. Hence, the aim of this study is to eval­u­ate the effi­cacy of pheromone trap­ping appli­ca­tion for con­trol­ling bag­worm, Metisa plana in Mukim Chaah small­hold­ings in Yong Peng, Johor, Malaysia. The instal­la­tion of pheromone traps at Mukim Chaah small­hold­ings was car­ried out at four dif­fer­ent loca­tions for two con­sec­u­tive gen­er­a­tions of M. plana. Results showed that the first and sec­ond gen­er­a­tions of pheromone trap­ping at Kg Sg Berlian and Kg Sawah Padi, with­out the aer­ial spray­ing of Bacil­lus thuringien­sis (Bt) have suc­cess­fully reduced 89% and 77% of bag­worm pop­u­la­tion, respec­tively. Mean­while, another trap­ping ses­sion con­ducted at Kg Teme­hel and Kg Seri Sep­a­kat, together with the aer­ial spray­ing of Bt, resulted in the first and sec­ond gen­er­a­tions of pheromone trap­ping to suc­cess­fully reduced 94% and 85% of bag­worm pop­u­la­tion, respec­tively. Together with the aer­ial spray­ing of Bt, the two con­sec­u­tive gen­er­a­tions of pheromone trap­ping appli­ca­tion at two dif­fer­ent areas in Mukim Chaah small­hold­ings suc­cess­fully reduced bag­worm pop­u­la­tion to man­age­able levels
