Secondary symbionts affect aphid fitness and the titer of primary symbiont

Abstract: Bacterial symbionts associated with aphids are important for their ecological fitness. The corn leaf aphid, Rhopalosiphum maidis (Fitch), is one of the most damaging aphid pests on maize and has been reported to harbor Hamiltonella defensa and Regiella insecticola while the effects of the secondary symbionts (S-symbionts) on host ecology and primary symbiont Buchnera aphidicola remain unclear. Here, four aphid strains were established, two of which were collected from Langfang - Hebei Province, China, with sim… Show more

“…Pectobacterium's ability to support P. bambucicola in feeding on hard bamboo stems suggests that a symbiotic relationship exists between the two organisms. Genetic distance analysis further supports the view that Pectobacterium present in P. bambucicola may represent a newly discovered species of aphid endosymbiont (Liu et al 2023).…”

“…Hence, some facultative symbionts enhance aphid resistance to natural enemies, such as parasitoid wasps (Hymenopetra: Braconidae) and arthropod predators, thereby providing protection against biological threats (Guo et al, 2017;Oliver et al 2003;Frago et al 2017). They can also influence aphid interactions with plant hosts, altering feeding behavior, host plant range, and susceptibility to plant defenses (Liu et al 2023).…”

“…This indicates that the production of offspring is uncoupled with the weight of each individual. This contrast with the results found in Rhopalosiphum maidis (Fitch) feeding on barley, where R. insecticola-infected aphids performed poorly in weight (Liu et al 2023). Regarding the distinct effect of R. insecticola on weight and reproductive performance in aphids of S. avenae sharing the same genetical background, again open questions about the undelaying mechanisms of these responses.…”

“…While aphids may gain benefits from hosting symbionts, negative effects could lead to the reallocation of aphid energy resources [62]. For instance, infection of the corn leaf aphid, Rhopalosiphum maidis (Fitch, 1856), with H. defensa and Regiella insecticola could have a partially negative effect on aphid growth and development, despite endosymbionts were maintained in aphids over time [63]. Previously, these two symbionts were shown to protect aphids, with R. insecticola shielding A. pisum from the aphid-specific fungal entomopathogen Zoophthora occidentalis [64], and H. defensa reducing aphid susceptibility to insecticides [31].…”
