(a) Quarantined infested areas.(1) Quarantined infested areas are those locations within this state in which the sapote fruit fly is currently found, from which dissemination of the pest or disease is to be prevented, and in which the pest or disease is to be eradicated.(2) There are no quarantined infested areas at this time.(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 three miles of each other or a mated female or one larva is trapped or otherwise discovered, a quarantined infested area shall be established around the site where the fly was trapped or otherwise discovered. The quarantined infested area shall consist of an area of approximately five miles in radius with the detection site at the center (roughly 80 square miles).(c) Core areas. One or more core areas may be established within each quarantined infested area around a detection site. Each core area shall consist of an approximately one square mile area with a detection site at or near the center. Each approximately square-shaped core area shall be defined by four GPS coordinates for each of its corners. Core areas shall be subject to more extensive monitoring and handling (including transportation and treatment) requirements. There are no core areas at this time. The establishment of any core areas shall be published in the Texas Register.
