In honey bees, brood care is a highly interactive and cooperative behavior, during which a single larva may be visited by nurse bees thousands of times, representing a prime environment for disease transmission. I investigated a potential social immune response to Israeli acute paralysis virus (IAPV) infection in brood care, hypothesizing that infection will result in a reduction in nursing behaviors. First, I tested for group-level effects by comparing three different social environments where 0%, 50%, or 100% of nurses were experimentally infected with virus. Then, I investigated individual-level effects by comparing the behavioral responses of individual infected and uninfected bees. I found no evidence for a social immune response in nursing behavior at the group level. However, individually, infected bees had more interactions with the larva than their uninfected nestmates. While this increase in interactions may increase virus transmission from adults to larvae, it could also be part of a hygienic response to increase grooming when an infection is detected. While this finding is intriguing, the reasoning behind the observed difference in brood care behavior, as well as the relationship between virus transmission and brood care, will need to be investigated further to better understand the disease dynamics of IAPV within this highly interactive and complex system.
