Figure 3.

Frequency of grooming behaviours in groups of five ants that were reared on either a 1 protein (P) : 3 carbohydrate (C) diet or a 3P : 1C diet and either were or were not challenged with the parasitic fungus M. anisopliae. Response variables are (a) antennal self-grooming or (b) nest-mate grooming (allogrooming) events during 30 s observation periods. Behaviours that occurred for more than a 5 s period were split into multiple events. Neither self-grooming nor allogrooming was significantly affected by rearing diet.
