Abstract
Heated water was tested as an alternative quarantine treatment method for ethylene dibromide fumigation to control Anastrepha suspensa (Loew) infestations of eggs and 1- to 2-day-old larvae in ‘Tommy Atkins’ and ‘Keitt’ Florida mangos. Submersion of fruit (size 8 to 12 or 881 ± 40–469 ± 18 g) for 45–65 min in water at 46.1–46.7°C produced 10 and 7 pupae, respectively, that did not eclose in an estimated treated population of 37,896 from ‘Tommy Atkins’ and 49,026 from ‘Keitt’ mangos. The treatment produced no visible injury to the fruit.
