APA treats reference materials as books. Encyclopaedia and dictionary entries  are formatted similarly to chapters in edited books but without page numbers. If there is no author listed for the individual entry, list the title of the entry in place of the author, and enclose the entry name in quotation marks for the in-text reference.

See the links below for examples.
