Fruit flies force their young to drink alcohol -- for their own good
Date:2/22/2013

wasps, this exposure reduces the level of NPF in the fly brain, causing the fly to seek out alcoholic sites for oviposition," Schlenke says. "Furthermore, the alcohol-seeking behavior appears to remain for the duration of the fly's life, even when the parasitic wasps are no longer present, an example of long-term memory."

Finally, Drosophila melanogaster is not unique in using this offspring medication behavior. "We tested a number of fly species," Schlenke says, "and found that each fly species that uses rotting fruit for food mounts this immune behavior against parasitic wasps. Medication may be far more common in nature than we previously thought."
