Buckley, R.C., & Gullan, P.J. 1991 More aggressive ant species (Hymenoptera: Formicidae) provide better protection for soft scales and mealybugs (Homoptera: Coccidae, Pseudococcidae).. Biotropica 23(3): 282-286.

Notes: Abstract: For 11 sets of interacting species in Papua New Guinea, coccoids attended by relatively inoffensive ants were more heavily parasitized than those attended by more aggressive ants.
