Deposits of crystalline or syrupy honeydews (or mannas) on plants have attracted attention since ancient times. (See Braun, 1938, for a review of early literature.) Essig (1942) points out that the "manna of the Wilderness" of Biblical accounts was honeydew produced by the coccid Trabutina mannipara (Ehr.), feeding on Tamarix trees.
