Baiting of Ceratitis capitata
Experiments carried out in the USA revealed that the addition of ammonia to baiting traps for Ceratitis capitata (EPPO A2 quarantine pest) increases the efficacy of these traps significantly. Trimedlure traps additionally equipped with a plastic vial containing a cotton wick with 2 ml of saturated ammonium carbonate solution caught 23% more male C. capitata flies than those with trimedlure only.
