Green and Farman compared growth and reproduction of booklice on combinations of paper and adhesive to booklice grown on diet specifically for booklice. The booklice thrived on the artificial diet but decreased in numbers and did not reproduce on paper and adhesive alone. During their experiment some booklice died and the survivors were observed feeding on them. The dead book lice may have sustained the life of the booklice survivors. They conclude that booklice need a source of food in addition to paper and glue such as mold or contamination with suitable food. They suggest that efforts to prevent mold and protect documents from spilled foods will provide good protection against booklice.
