Quarantine treatment for courgettes infested with Bactrocera cucumis
Bactrocera cucumis (EPPO A1 quarantine pest as a non-European tephritid) is a serious pest of cucurbits, tomato and papaya and is distributed in Australia only. Experiments have been conducted in Australia to test the efficiency of a vapour-heat treatment for courgettes infested with B. cucumis. Courgettes infested with 22 h old eggs of the pest were completely disinfested using the vapour-heat treatment of 45ø C with ;94 RH for 30 min. An estimated total of 178 219 eggs were treated without survivors, thus achieving probit 9 (99,9968% mortality). It was also found that the eggs of the pest were significantly more tolerant to heat than first, second and third instars of B. cucumis.
