# gst: how a virus could cause context-dependent manipulation in host social behavior

<< Honey bees that guard hive entrances are twice as likely to allow in trespassers from other hives if the intruders are infected with the Israeli acute paralysis virus, a deadly pathogen of bees, >>

<< It seems that the virus is changing how the bees smell, and perhaps the infected bees also are behaving in a way that is meant to appease the guards by engaging more in trophallaxis (a process by which honey bees exchange regurgitated food and other liquids), >> Adam Dolezal
