Functional response of Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) to Aphis gossypii Glover (Homoptera: Aphididae) in the Laboratory

Functional responses of immature stages of Propylea quatuordecimpunctata (Coleoptera: Coccinellidae) to Aphis fabae (Hemiptera: Aphididae)

“…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).…”

Intraguild interactions between the predatory hoverfly Episyrphus balteatus (Diptera: Syrphidae) and the Asian ladybird, Harmonia axyridis (Coleoptera: Coccinellidae): Effect of larval tracks

“…Aphidophagous hoverflies and ladybirds are known to exploit temporary aphid colonies as food resources and significantly suppress aphid abundance (Chambers & Adams, 1986;Dixon, 1985;Dixon et al, 1997;Lee & Kang, 2004). It has been also demonstrated that the survival of the larvae of these aphid predators and their efficiency in reducing aphid populations mainly depends on the quality and the quantity of the patches of aphid prey (Kan, 1988;Hemptinne et al, 1993;Kindlmann & Dixon, 1993;Almohamad et al, 2007Almohamad et al, , 2008.…”

Functional response of the lady beetle Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) on the aphid Myzus persicae (Sulzer) (Homoptera: Aphididae)

“…Those of H. axyridis have been reported on Aphis gossypii Glover (Lee and Kang, 2004), and on Aphis craccivora Koch (Mogi, 1969); however, most other studies have only researched its functional response at the fourth instar or adult stages. In H. axyridis, functional responses of each instar larva and adult should be considered for each prey species, because H. axyridis exhibit different responses to various prey species (Pervez and Omkar, 2005), i.e.…”

“…Type I (Luo, 1987), Type II (e.g. Mogi, 1969;Lee and Kang, 2004), and Type III (Hu et al, 1989). The green peach aphid Myzus persicae Sulzer is a major insect pest due to the transmission of plant viruses (Harris and Maramorosch, 1977;Matthews, 1991), and resistance to insecticides (Devonshire, 1989;Quaclia et al, 1993); however, no detailed study has been conducted on its functional response to M. persicae, although H. axyridis is a well-known predator of M. persicae (e.g.…”
