Studies on the Predatory Biology of Oriental Dacetine Ants(Hymenoptera: Formicidae). Ⅲ. Predation on Gamasid Mites by Pyramica mazu with a Supplementary Note on P. hexamerus

摘要

Ants of the myrmicine tribe Dacetini are mostly specialized predators of Collembola. Prey records in the field, however, indicated that the short-mandibulate species Pyramica mazu (Terayama, Lin and Wu) predates upon gamasid mites. In the laboratory, this ant readily hunted and consumed gamasids as well as collembolans and symphylans. Evidence for specialized predation on Diplura in Pyramica hexamerus (Brown) was supported by field data.
