Scope of the treatment
|
[4]
|
This treatment comprises the vapour heat treatment of fruit of Mangifera indica to result in the mortality of eggs and larvae (of all ages) of Ceratitis capitata (Mediterranean fruit fly) at the stated efficacy1.

Treatment schedule
|
[12]
|
Exposure in a vapour heat chamber:
|
[13]
|
at a minimum of 95% relative humidity
|
[14]
|
with air temperature increasing from room temperature to 47 °C
|
[15]
|
for at least two hours or until fruit core temperature reaches 46.5 °C
|
[16]
|
followed by ten minutes at a minimum of 95% relative humidity in an air temperature of 47 °C and with fruit pulp temperature at a minimum of 46.5 °C (seed surface of largest fruit).
|
[17]
|
Recording interval is five minutes. Once the treatment is complete fruits are hydro-cooled in a shower of water to reach ambient temperatures in less than 40 minutes.
|
[18]
|
The efficacy is effective dose (ED)99.9968 at the 95% confidence level.

Other relevant information
|
[20]
|
In evaluating this treatment the Technical Panel on Phytosanitary Treatments (TPPT) considered issues associated with temperature regimes and thermal conditioning, taking into account the work of Hallman and Mangan (1997).
|
[21]
|
This schedule was based on the work of Heather et al. (1997) and developed using the “Kensington” cultivar of M. indica. The egg stage was found to be the most thermotolerant among pre-puparial stage of C. capitata from 41 ºC to 44 ºC; however, at 45 ºC the third instar appeared to be slightly more thermotolerant.

Footnote 1: The scope of phytosanitary treatments does not include issues related to pesticide registration or other domestic requirements for contracting parties’ approval of treatments. IPPC adopted treatments may not provide information on specific effects on human health or food safety, which should be addressed using domestic procedures prior to contracting parties approving a treatment. In addition, potential effects of treatments on product quality are considered for some host commodities before their international adoption. However, evaluation of any effects of a treatment on the quality of commodities may require additional consideration. There is no obligation for a contracting party to approve, register or adopt the treatments for use in its territory.
