abstract
The present investigation on Food consumption and conversion efficiency of Spodoptera litura (Fab.) on different germplasms of soybean was carried out during the year 2015-16. Among the different genotypes of soybean, genotype JS-20-34 along with AMS-1003, AMS-1002, AMS-115 and AMS-243 recorded lowest Approximate digestibility (AD), Efficiency of conversion of ingested food (ECI) and Efficiency of conversion of digested food (ECD) values whereas, JS-335 which is susceptible check recorded highest AD, ECI and ECD values along with AMS-358 and AMS-77. In case of consumption index the soybean genotypes JS-20-34, AMS-1003, AMS-243, AMS-115, and AMS-1002 exhibited lowest consumption index values. Whereas, genotypes JS-335, JS-358 and JS-77 recorded highest CI values. The nutritional indices are appropriate tools in host plant resistance evaluation and they also could provide profound understanding of the behavioral and physiological bases of insect-host plant interactions.
