Non-chemical disinfestation: combining the combinations - additive effects of the combination of three postharvest treatments on insect mortality and pome fruit quality.

Experiments were conducted on the disinfesting potential of a combination of 3 postharvest treatments (mild heat, low oxygen, cold storage) which have previously been evaluated in pair combination. The combination of the 3 produced additive effects on the mortality of codling moths (Cydia pomonella), light brown apple moths (Epiphyas postvittana) and Queensland fruit flies (Bactrocera tryoni). For example, it gave a synergy factor of 15 on mortality of the fifth instar larvae of codling moth. The combination was tested for its influence on the quality of pears (cv. Packham's Triumph) and apples (cultivars Royal Gala, Red Delicious, Fuji and Pink Lady). The pears were tolerant of the maximum treatment (72 h under controlled atmosphere at 30 deg C, followed by 5 weeks at 0 deg C under air). Some apple fruits (particularly Pink Lady) developed off-flavours, which will impose restrictions on the duration of the first part of the treatment. A general trend of reduced ethylene production and better ma

intenance of firmness was observed in apple fruits as a response to this treatment.
