(b) Creating, modifying, or extending quarantined infested areas. When five or more adults of the sapote fruit fly are trapped or otherwise discovered within a time period equal to one fly generation and within 3 miles of each other or a mated female or one larva is trapped or otherwise discovered, a quarantine area shall be established around the site where the fly was trapped or otherwise discovered. The area quarantined shall consist of an area of approximately 5 mile radius with the detection site at the center (roughly 81 square miles).

Each core area shall consist of an approximately 1.0 square mile area with a detection site at or near the center. Each approximately square-shaped core area is defined by four GPS readings for each corner of the core area. Core areas are subject to more extensive monitoring and handling (including transportation and treatment) requirements. The following areas are declared to be core areas: None at this time.
(d) Core areas are shown on the map of the quarantined area referred to in subsection (a) of this section. Additional core areas, if any, shall be published by the department in the In- Addition section of the Texas Register as they are established.
