The noctuid pod borer, Helicoverpa armigera, is one of the most important pests of pigeonpea, and host plant resistance is an important component for minimizing the extent of losses caused by this pest. To develop insect resistant cultivars and hybrids, it is important to understand the contributions of different components of resistance, and therefore, we studied the antixenosis and antibiosis mechanisms of resistance to H. armigera in a diverse array of pigeonpea genotypes (prominent cultivars and hybrids) using leaf, flower, and pod bioassay’s, under no-choice and multi-choice conditions. Antixenosis for oviposition was observed in case of ICPH 3461, ICPL 332 WR, BSMR 853, ICPH 3762 under no-choice, and multi-choice conditions. Whereas, above-mentioned genotypes exhibited higher levels of antibiosis and can be used as sources of non-preference mechanism of resistance in pigeonpea improvement programs to breed for resistance to H. armigera.
