Abstract

Nutritional influence of three prey species namely Spodoptera litura (Fabricius), Raphidopalpa foveicollis Lucas and Chrotogonus sp. on the biology and biochemistry of Rhynocoris marginatus (Fabricius) was examined in the laboratory at 30±2°C, 75-80 percent relative humidity and 11-13h photoperiod. Newly emerged nymphs were reared singly on the three prey species separately and followed through all life stages until the predator died. Developmental period of nymphs was longer on R. Foevicollis (100.08±9.06 days) than on Chrotogonus sp. (85.52± 10.14 days) and minimum developmental period was recorded on S.litura (69.36±6.75 days). Maximum fecundity and longevity was recorded on S. Litura fed category. The biochemical constituents such as carbohydrates, proteins and lipids were also higher in S.litura fed R. marginatus.
