Abstract:Guavas from a commercial field near Homestead, FL, that were naturally infested with Caribbean fruit flies, Anastrepha suspense (Loew), were coated with Nature Seal 2000, Nature Seal containing 4% hydroxypropyl cellulose, or Pac-Rite TFC 213 (a carnauba wax). Precoating infestation rates ranged from 0 to 3.2 larvae per guava, and the mean Caribbean fruit fly survival in guavas coated with Nature Seal (4%), Nature Seal 2000, or Pac-Rite TFC 213 was 9, 46, and 68%, respectively, compared with uncoated controls. Mean days to 50% emergence was 18.2 d for larvae in guavas coated with Nature Seal (4%); this was significantly longer (95% CL) than the mean to 50% emergence for larvae in uncoated guavas (13.4 d) or those in guavas coated with Pac-Rite TFC 213 (13.2 d). Carbon dioxide levels were generally higher and oxygen levels generally lower in Nature Seal-coated guavas compared with uncoated guavas. Coatings can lower Caribbean fruit fly survival rates in guavas and might become a component of a systems approach to allow export of guavas from Florida to' parts of the world that require fruit fly treatment.
