Rearing of C. septempunctata was carried out at 21.3±4.00°C and 78.8±9.44% relative humidity. The first, second, third and fourth larval instars of C. septempunctata consumed 20.3, 54.3, 108.2, and 232.7 M. rosea, respectively. The predation efficacy of the C. septempunctata was increased with the progress of the larval instars up to the fourth which was the most voracious.trueCoccinella septempunctata | Macrosiphum rosae | Predition efficiencyArticle10.17582/journal.pjz/2017.49.1.345.3492-s2.0-85041671932
