Control of Caribbean fruit fly (Diptera: Tephritidae) in navel orange by forced hot air

A single-stage, hot-air quarantine treatment was used to kill Caribbean fruit fly, Anastrepha suspensa (Loew), mature 3rd instars in Florida-grown 'Golden' navel orange, Citrus sinensis (L.) Osbeck. Treating infested navel orange with 48 +/- 0.3 degrees C forced air for 55.9 +/- 0.3, 73.7...

Description
Summary:A single-stage, hot-air quarantine treatment was used to kill Caribbean fruit fly, Anastrepha suspensa (Loew), mature 3rd instars in Florida-grown 'Golden' navel orange, Citrus sinensis (L.) Osbeck. Treating infested navel orange with 48 +/- 0.3 degrees C forced air for 55.9 +/- 0.3, 73.7 +/- 1.3, and 119.4 +/- 0.7 min, to reach final center pulp temperatures of 36-37, 40-41, and 44-45 degrees C, respectively, when initial center pulp temperatures were 22.3 +/- 0.2, 21.2 +/- 0.2, and 20.5 +/- 0.3 degrees C, respectively, reduced the number of surviving puparia that developed from treated larvae. The exposure time needed to reach Q99.9968% mortality was 108.6 min (lower and upper fiducial limits were 88.4 and 200.3 min, respectively) when the final mean center pulp temperature was greater than or equal to 44 degrees C. A large-scale confirmatory test resulted in no survivors when 113,676 Caribbean fruit fly larvae in 1,200 manually infested navel oranges were heated with 48 +/- 0.3 degrees C forced air at an average 0.75 m3/s air flow rate until the center pulp temperatures were greater than or equal to 44 degrees C, which required 100.2 +/- 3.0 min of heating when initial center pulp temperatures were 23.2 +/- 0.4 degrees C. Relative humidity ranged from 63.5% at the start of the test to 77.3% when the test was finished. After treatment at 48 +/- 0.3 degrees C for 105 min and 1 mo of storage at 5 degrees C, there was no significant difference in quality characteristics between heated and unheated navel oranges
