Economic importance
While species in this genus are common and widespread, there appears to be limited economic importance to this genus.

Molecular resources
At this time Genbank has no molecular data for this genus, although it has limited data for Muirodelphax arvensis (as Delphacodes campestris) (here). BOLD provides barcode data for Muirodelphax aubei (here). Urban et al. (2010) extracted 18S rDNA, 28S rDNA, wingless, and cytochrome oxidase I from Muirodelphax aubei, Muirodelphax arvensis (as Delphacodes campestris), and Muirodelphax atralabis.(as Delphacodes atralabis) for their analyses.
