Abstract : The efficacy of hot water as a quarantine treatment against 1- to 6-day-old larvae of Anastrepha obliqua and A. suspensa in mangoes was determined in laboratory studies. The submersion time needed to reach 99.9968% mortality (probit 9) was 58.0 and 44.3 min at 46.1-46.7°C for A. obliqua and A. suspensa, respectively. Mangoes submerged at this temperature for 75 min and then stored at 25-27°C for 8 days or submerged for 2 h at 46.1-46.7°C and stored for 7 days at 11.1°C, were not damaged. The percentage of acceptable mangoes following hot water treatment decreased as submersion time at 46.1-46.7°C increased to 4 h, when all fruits were damaged and were not acceptable after storage at 11.1°C for 7 days.
