The biology and feeding potential of Sphaerophoria javana Wied, were studied in the laboratory at 27.9±1.1° C and 85.7±5.2 percent relative humidity, on Aphis craccivora Koch, a common pest of Dolichos lablab L. The egg, larval and pupal stages occupied 1.96±0.07, 6.30±0.22 and 5.38±0.04 days, respectively. The total life cycle was completed in 14.02±0.2 days. The per day consumption of first, second and third instar larvae was 12.7±2.2, 69,4±7.4 and 112.2±7.7 aphids, respectively.Keywords

The biology and feeding potential of Coccinella septempunctata Linnaeus were studied in the laboratory at 27±2°C and 70±5 per cent relative humidity on Macrosiphoniella sanborni (Gillette), a common pest of chrysanthemum. The egg, larval, prepupal and pupal stages occupied 2.41±0.19, 9.35±1.2, 0.73±0.1 and 3.53±0.08 days, respectively. The adult female laid 330.8±28.3 eggs in groups of 30 to 60. The sex ratio (female:male) was 1.5:1. The adult longevity was 10-19 days in male and 26-35 days in female. The feeding potential of first, second, third and fourth instar grubs and adult was 9.17±1.5, 20.8±3.3, 34.1±3.5, 37.5±4.7 and 55.3±6.7 aphids/day/individual, respectively.Keywords
