Quarantine treatment of blueberries against Bactrocera tryoni
The efficacy of cold storage of blueberries against Bactrocera tryoni (EPPO A1 quarantine pest) was tested in Australia. Vaccinium ashei and V. corymbosum were artificially infested with immature stages of B. tryoni and stored at 1.0 + 0.2°C for several days. It was observed that the 1st instar larva is the most cold-tolerant life stage. It was also shown that cold storage at 1°C for 12 days was an effective quarantine treatment, as no larvae out of 100.000 tested was able to survive.
