Aphid Species Affect Foraging Behavior of Coccinella septempunctata (Coccinellidae: Coleoptera)

Muhammad Umar Farooq , Hafiz Faqir Hussain Qadri and Muhammad Ahmad Khan

Background: Flowers are admirable in scenic good looks and artistic beautification. These are also playing necessary roles in therapeutic preparations. Aphid is an important sucking pest of various flowers in ornamental territories and it is generally controlled by predators, so it was necessary to evaluate which aphid species affect the predator more or less. Materials and Methods: Biocontrol agent Coccinella septempunctata was used against cosmos aphid (Aphis spiraecola, rose aphid (Macrosiphum rosea), gul e ashrafi aphid (Aphis fabae), kaner aphid (Aphis nerii), chandni aphid (Sitobion avenae), dahlia aphid (Myzus persicae) and annual chrysanthemum aphid (Macrosiphoniella sanborni). Results: The grub of C. septempunctata consumed 283.8±9.04 M. rosea, 487.7±12.6 M. sanborni, 432.75±16.02 A. spiraecola, 478.2±8.07 A. fabae, 552.3±9.04 M. persicae, 142±1.32 A. nerii and 498.5±13.09 S. avenae in its whole larval life. The M. persicae and M. rosea consuming grubs showed 100% adult emergence while, M. sanborni, A. spiraecola, A. fabae and S. avenae showed 96.58, 89.02, 94.78 and 75.45% adult emergence, respectively. Conclusion: The C. septempunctata has significant predatory potential against A. spiraecola, M. rosea, A. fabae, S. avenae, M. persicae and M. sanborni except A. nerii. Thus, further studies are needed to find out alternate predator to control A. nerii on ornamentals.
