The quarantine established by this subchapter shall remain in effect until the sapote fruit fly is eradicated. The sapote fruit fly shall be considered eradicated from the quarantined area when no additional sapote fruit flies are detected for a time period equal to three consecutive generations after the most recent detection. For the sapote fruit fly, the number of days required to complete a reproductive cycle, i.e., one generation, is dependent upon temperature. Therefore, a day-degree model will be used to calculate the duration of each consecutive generation.
