Abstract

Hot-water quarantine treatment to control fruit flies in mangoes imported into the United States from Peru.

Abstract

Heated water was tested as a quarantine treatment for controlling infestations of the Mediterranean fruit fly, Ceratitis capitata; West Indian fruit fly, Anastrepha obliqua; Anastrepha fraterculus and Anastrepha distincta in mango imported from Peru. Immersing infested fruit for 10-70 min at 46.1 +/-0.25degC reduced the number of surviving pupae that developed from treated larvae. Probit analysis of the data estimated the immersion times needed to reach 99.9968% (Probit 9) mortality as 76.1 min for C. capitata, 113.4 min for A. obliqua, 75.6 min for A. fraterculus, and 65.8 min for A. distincta. Large-scale confirmatory tests for C. capitata and A. obliqua resulted in no survivors based on normal appearing pupae when 148 925 C. capitata in 3710 infested mangoes and 122 417 A. obliqua in 4118 infested mangoes were immersed in water at 46.1 +/-0.25degC for 90 min.
