The trap development for the Tobacco bud worm Spodoptera litura  is still long way to go for perfecting for trapping with higher efficiency. (YASHIMA and TAMAKI,1974) started the developing a trap for this insect when  TAMAKI et al.,1973 first identified its pheromone chemical. Later, based on the recommendation of  TDRI, London, it was PAWAR et al.,1984 and 1988 perfected a trap for Helicoverpa armigera at ICRISAT. When RANGA RAO joined ICRISAT, he  developed a procedure for trapping this insect. Further, on the above observations, NANDAGHOPAL and RATHOD (2007) reported a tarp with higher efficiency
