Changes in emergence parameters as a result of transporting sterile Queensland fruit fly 'Bactrocera tryoni' (Froggatt) (Diptera: Tephritidae) pupae

Emergence of sterile Queensland fruit fly was assessed at the Camden mass-production facility and at the Yanco release centre in New South Wales between November 2002 and January 2005. Pupal weight was positively and significantly related to the percentage emergence at both Camden and at Yanco. However, average emergence rates fell from 82.1% at Camden to 68.4% at Yanco. The date of larval hopping at Camden influenced percentage emergence. Pupal weights for the 4th, 5th and 6th days of larval hopping were more likely to significantly influence the percentage emergence of flies than it did on the first three days of hopping.
