Factors driving susceptibility and resistance in aphids that share specialist fungal pathogens (original) (raw)

Highlights  Two aphid species in cereals, Sitobion avenae and Rhopalosiphum padi, share the fungal pathogens Pandora neoaphidis and Entomophthora planchoniana  Aphid behavior and aphid morph are important factors governing host susceptibility and resistance, and endosymbionts may also play a role  The life cycles of hosts and pathogens are influential to transmission routes of pathogens from conspecific to heterospecific host  Laboratory experiments suggest that the conspecific host is more susceptible than the heterospecific host  Secretome analysis of entomophthoralean infection in S. avenae suggest a weak hosts immune response
