Food intake, assimilation, tissue growth, approximate digestibility (A.D.), efficiency of conversion of digested (E.C.D.) and ingested food (E.C.I.) of coccinellid, Harmonia dimidiata ( Fabricius) on Cervaphis rappardi indica Basu were studied under laboratory conditions. On this prey, duration of the feeding period, fresh weight of food ingested, faeces produced and weight gain by the predator were recorded for computing quantitative nutritional parameters. The results revealed that food ingestion, egestion, assimilation and tissue growth increased with increase in biomass. The value of A. D. was highest in the first instar and showed a gradual decline as larvae matured. The maximum E.C.D. and E.C.I. were observed in second instar larvae. The consumption rate of predator showed a significant positive relationship with assimilation, egestion and tissue growth.Downloads
