Quarantine treatment of lemons against Bactrocera tryoni and Ceratitis capitata
In Australia experiments were carried out to evaluate the efficacy of a cold storage quarantine treatment for the disinfestation of lemons against Bactrocera tryoni (EPPO A1 quarantine pest) and Ceratitis capitata (EPPO A2 quarantine pest). Lemons were artificially infested with immature life stages of B. tryoni or C. capitata and then subjected to cold storage of 1ø C for 14 d. First instars of B. tryoni and second instars of C. capitata proved to be the most cold-tolerant life stages of the fruit flies, but none of >43 000 B. tryoni first instars and >30 000 C. capitata second instars survived this described cold storage treatment. The fruit quality of lemons was not negatively influenced by the cold storage even if it lasted for 32 d.
