Reported median body size for this species (Length mm; width micrometers; weight micrograms) - Click:
Recorded from Idaho, USA forming seed galls in sand dropseed grass Sporobolus cryptandrus (Poaceae) (Barrantes-Infante et al., 2018)..
Afrina sporoboliae small ovoid galls on stems, leaves and rarely in flower heads (Barrantes-Infante et al., 2018)
Seed gall nematodes are quarantine pesets in many countries.
Induces seed development into black galls.
Grasses
Galls contain as many as 9 adults and numerous eggs and juveniles (Van den Berg, 1985).
Ecophysiological Parameters:
Seed gall nematodes are frequently associated with bacterial pathogens of the genus Rathaybacter. Afrina sporoboliae is potentially a vector of a new species of Rathayibacter that causwes bacterial head blight of Sporobolus cryptandrus..Most of the collections of sand dropseed galls collected in Idaho that were positive for Afrina sporoboliae also included light-colored seed galls tcontaining nearlyy pure cultures of a Gram-positive bacterium that were identified as Rathaybacter. (Barrantes-Infante et al., 2018)
