Quarantine treatment of carambolas against Anastrepha suspensa

In Florida, US, gamma irradiation was studied in relation to its potential to be used as a quarantine treatment for carambolas (Averrhoa carambola) against Anastrepha suspensa (EPPO A1 quarantine pest). Over 100000 immature fruit flies infesting carambolas were subjected to a 50 Gy ionizing gamma radiation which resulted in no survivors and fulfilled the probit 9 security level. The dose did not cause any observable damage to the fruits.
