“…Type II functional responses are generally associated with invertebrate predators (Hassell et al, 1977) and they are also common among aphidophagous coccinellids. Thus, a type II response is recorded for fourth instar larvae and adults of Coccinella undecimpunctata L. feeding on Myzus persicae Sulzer (Cabral et al, 2009), all four larval stages and female adults of Harmonia axyridis Pallas feeding on Aphis gossypii Glover (Lee & Kang, 2004), third instar larvae and adults of H. axyridis and Coccinella septempunctata L. feeding on A. glycines Matsumura (Xue et al, 2009), fourth instar larvae and female adults of Coleophora inaequalis F. feeding on Toxoptera citricida Kirkaldy (Wang & Tsai, 2001), adults of Cheilomenes sulphurea Olivier feeding on A. fabae (Hodek et al, 1984) and female adults of Adalia bipunctata L. feeding on M. persicae (Jalali et al, 2010). This type of response may destabilize predatorprey interactions (Oaten & Murdoch, 1975) and is theoretically less capable of suppressing prey populations compared to a type III functional response (Holling, 1965).…”
