• Insect immune resistance to parasitoids (2008, background): “…and host resistance has been described in the Acyrthrocyphon pisum -Aphidius ervi interaction (Henter & Via, 1995; Hufbauer & Via, 1999), but the immune processes are basically unknown in aphids and symbiotic micro-organisms are involved in the resistance phenomenon (Oliver et al., 2003; 2005).”
• Access to mutualistic endosymbiotic microbes: an underappreciated benefit of group living (2008, background): “Indeed, aphid variation in resistance to parasitism by the parasitoid wasp Aphidius ervi is correlated with genetic variation in the aphid’s bacterial endosymbiont Hamiltonella defensa rather than with variation in aphid genotype (Oliver et al. 2005).”
• Parasitism, commensalism, and mutualism: exploring the many shades of symbioses (2008, background): “pisum can also harbour a range of facultative secondary symbionts, one of which is Hamiltonella defensa which confers to its host resistance against attack by parasitoid wasps (Oliver et al. 2005).”
• Facultative ‘secondary’ bacterial symbionts and the nutrition of the pea aphid, Acyrthosiphon pisum (2006, background): “…2000; Tsuchida et al., 2004), thermal tolerance (Montllor et al., 2002; Russell & Moran, 2006) and resistance to parasitoids and fungal pathogens (Oliver et al., 2003, 2005; Ferrari et al., 2004; Scarborough et al., 2005), although the extent of these effects varies with aphid and bacterial…”
• Multiorganismal Insects: Diversity and Function of Resident Microorganisms (2014, background): “The secondary symbiont Hamiltonella defensa confers pea aphid resistance to the parasitoid Aphidius ervi (88), but not all Hamiltonella spp.”
• The natural occurrence of secondary bacterial symbionts in aphids (2016, background): “With additional sequencing effort, different isolates of each symbiont can also be investigated (Oliver et al., 2005; Vorburger et al., 2010; Henry et al., 2015).”
• Bacterial symbionts as mediators of ecologically important traits of insect hosts (2011, background): “While oviposition rate of the parasitic wasp was not altered by the presence of secondary endosymbionts, rates of successful parasitism were reduced by increased death rate of wasp larvae developing in aphid hosts (Oliver et al., 2003, 2005).”
• Nine facultative endosymbionts in aphids. A review (2017, background): “However, the most famous effect of H. defensa is that this bacteria protect aphid against parasitoid wasps by disturbing their development inside aphid host (Oliver et al., 2003; 2005; 2008) and the level of protection depends on various factors.”
• Arthropod symbioses: a neglected parameter in pest- and disease-control programmes (2011, background): “Oliver et al. (2003) demonstrated that the development of resistant populations is owing to differences in secondary”
• Cowpea aphid (Aphis craccivora) associated with different host plants has different facultative endosymbionts (2013, background): “Hamiltonella has been shown to confer resistance to parasitoid wasps in A. pisum (Oliver et al ., 2010) and Hamiltonella transferred from A. craccivora to A. pisum has also been shown to be defensive (Oliver et al ., 2005).”
• Cryptic Species of Parasitoids Attacking the Soybean Aphid (Hemiptera: Aphididae) in Asia: Binodoxys communis and Binodoxys koreanus (Hymenoptera: Braconidae: Aphidiinae) (2009, background): “…the bacterial endosymbiont Hamiltonella defensa Moran, and previous studies suggested that these endosymbionts were probably involved in resistance of A. craccivora to B. communis (Desneux et al. 2009b) as is the case for H. defensa in the pea aphid, Acyrthosiphon pisum (Oliver et al. 2003, 2005).”
