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).
