Population density and damage by pod borers, helicoverpa armigera and spodoptera exigua in a diverse array of chickpea genotypes under natural infestation in the field

摘要: Host plant resistance is one of the important components to insects, and hence, we evaluated a diverse array chickpea genotypes for pod borers, Helicoverpa armigera Spodoptera exigua under field conditions. Data were recorded on S. egg masses larvae, H. eggs damage at vegetative, flowering podding stages, grain yield crop harvest. During vegetative stage, significantly lower numbers larvae ICC 10393, ICCL 86111, 12475 RIL 20; while leaf was 12475, ICCV 10, 25 as compared that 3137. 20, 25, KAK 2, 10 than 3137; which 3137 in or both sowings/seasons. and/or larval densities suffered seasons. Pod EC 583264, 20 The these also greater sowings/seasons, can be used improving borer sustainable production.
