The purpose of the paper is to determine the longevity, half life and the release rates of Pheromone lures from three commercial companies in India for the Spodoptera litura. Pheromone lures was extracted and examine by the use of Gas chromatography (GC). The major component was detected as ZE-9, 12: 14Ac. Lures from Natural Resource Institute (NRI), Basarass, Agriland as well as PCI lure for the use on Spodoptera litura was aged in cotton field in India in various dispensers like polyethylene vials, rubber tubes, and rubber septum. The result of this research work shows that the standard NRI lures had their lure impregnated with 0.89mg as initial dose and 5.63% remaining life at the 6 th week. Basarass pheromone company lure had 0.1mg as initial dose and 12.88% at the end of 6 th week, PCI company lure had-0.01mg as initial dose and 7.84% remaining life at the end of the 6 th week, Agriland company lure was impregnated with 0.05mg as initial dose and 48.02% remaining life at 6 th week respectively. The conclusion that was drawn is that companies like Basarass and Agriland do not put enough milligram (mg) of the major component and the release rates fluctuates on the field due to impurities and this had given the cure some measure of longevity with adverse effect on the performance. Among the recommendations that have been made in this paper companies should endeavor to increase the amount of milligrams impregnated in the lure and find the means and ways of increasing longevity without compromising on the fast release of the major component.
