Incidence of parasitism by Aphidius rhopalosiphi in colour forms of the aphid Sitobion avenae

Abstract: Aphidius rhopalosiphi parasitises green colour forms of Sitobion avenae more frequently than brown forms. The handling time is longer for brown than for green nymphs, even when the two forms are members of the same clone. Parasite development lasts longer in brown forms than in green forms, and mortality is higher.

“…The biological signiÞ-cance of variation in body pigmentation also is not fully understood. In aphids that show genetically based color variation, body color has been found to be associated with differences in developmental and reproductive rates (Araya et al 1996), resistance to parasitism (Ankersmit et al 1981(Ankersmit et al , 1986, and attack rates by natural enemies (Losey et al 1997, Libbrecht et al 2007.…”

“…Adverse effects of future global change on green pea aphids may alter the availability of suitable hosts for a key top-down population regulatory factor; but see also Hoover & Newman (2004). Other aphid species also exhibit colour polymorphisms that affect their vulnerability to natural enemies (Ankersmit et al, 1986;Kuosell & Eggers, 1987;Michaud & Mackauer, 1995), fungal pathogens (Yu et al, 1995) and synthetic insecticides (Kerns & Gaylor, 1992). Thus, if our accumulating knowledge accurately reflects the asymmetric effects of elevated CO 2 on pea aphid genotypes, global change may affect our ability to control aphids using biological and chemical methods.…”
