Aphid effects
Galls of B. dracunculifoliae with higher aphid inquilinism presented lower volume, and higher nymph mortality (link 1). Mortality of parasitised nymphs was also higher in galls with aphid inquilines (link 2). On plants with more branches occupied by aphids, parasitism of the galler B. dracunculifoliae was lower (link 15).
