In the parishes within the jurisdiction of the authority, in all felony and misdemeanor prosecutions, including traffic offenses, under state law or parish or municipal ordinance, in any district, parish, city, or mayor's court, special costs in the amount of seven dollars and fifty cents shall be levied against every defendant who is convicted after trial or who enters a plea of guilty or nolo contendere or who forfeits bond.
