SCREENING ELITE GENOTYPES AND IPM OF DEFOLIATORS IN GROUNDNUT RASHMI S. YAMBHATANL 2010 Dr.R.K. PATIL Major Advisor ABSTRACT Screening elite genotypes and IPM of defoliators in groundnut were studied during Kharif 2009, at Main Agricultural Research Station, UAS, Dharwad. The seven groundnut genotypes were screened for Spodoptera litura (F.) resistance in the field. The genotypes viz., Mutant-III and ICGV-86699 Tan showed 11.5 and 12.0 per cent leaf damage compared to 44.0 per cent foliar damage in susceptible check, JL-24. The detailed investigation on biology of S. litura on these seven genotypes further confirmed with the field screening studied by recording longest larval period (22.83 and 23.67 days), pupal period (11.67 and 11.33 days), lowest adult longevity (9.67 and 9.33 days) and fecundity (379.67 and 386.0 eggs/ female) in Mutant-III and ICGV-86699 Tan respectively. Whereas susceptible check, JL-24 has recorded shortest larval period (17.93 days), pupal period (9.83 days), higher adult longevity (11.83 days) and fecundity (592.0 eggs/ female). The resistant genotypes, Mutant-III and ICGV-86699 Tan permitted S. litura to complete its life cycle in longest period (48.92 and 49.00 days respectively) compared to susceptible varieties, JL-24 and GPBD-4 (41.02 and 41.00 days respectively). The other genotypes GPBD-5, GPBD-6 and ICGV-86699 Red were intermediate. The effects of these resistant genotypes on the growth and development of S. litura could obviously be due to chemical factor i.e. antibiosis. Among different IPM modules, Module-II proved as effective IPM module in reducing defoliator population, enhancing natural enemy population and recording higher yield (39.95 q/ha) with maximum net returns (Rs.89,850/ha) and highest C:B ratio (1:5.1) followed by Module-I. Module-II comprising of foxtail millet as intercrop (7:1) and insecticide Emamectin benzoate (0.2 ml/lit) and M-I was totally bio-intensive module and it comprising of sunflower as trap crop and Nomuraea rileyi spray and it was suitable for northern transitional belt.
