Field efficacy of transgenic maize event TC1507 expressing the Cry1F protein (containing event DAS-slashed zero 15 slashed zero7-1), event MON-slashed zero slashed zero 81slashed zero-6 and the stacked hybrid expressing Cry1F and Cry1Ab proteins (containing event DAS-slashed zero 15 slashed zero 7-1xMON-slashed zero slashed zero 81 slashed zero-6xMON-slashed zero slashed zero 6 slashed zero 3-6) against the four secondary lepidopteran pests, namely: common cutworm (CCW) Spodoptera litura (Fabricius), true armyworm (TAW) Mythimna separate (Walker), corn earworm (CEW), Helicoverpa armigera (Hubner), and corn semi-looper (CSL) Chrysodeixis eriosoma (Doubleday) was evaluated during the 2012 dry season in two regulated filed trials in Cauayan, Isabela and Alcala, Pangasinan [Philippines]. TC1507 provided effective control against CCW, CEW and CSL, and presented a new mode of action against the primary pest, the Asian corn borer (ACB) Ostrinia furnacalis (Guenee). On the other hand, the triple stacked hybrid (TC1507xMON810xNK603) provided effective control against all four secondary lepidopteran pests. The combined trait product offers broader spectrum for lepidopteran pest control aside from its excellent performance against ACB.
