Studies on traps and attractants for Ceratitis capitata
In Spain, comparative studies have been carried out in peach orchards on the type of traps and attractants for Ceratitis capitata (EPPO A2 quarantine pest). Several combinations of traps (Tephri, Jackson and Delta) and attractants (Nu-Lure, Trimedlure, ammonium acetate, putrescine (1-4 diamminobutane), ammonium salts) have been tested and their effectiveness was evaluated for both males and females. Concerning the type of trap, results showed that the greater number of captures was obtained with the Tephri traps, whereas the Jackson and Delta traps were less effective, especially for females. Concerning the type of attractant, the authors stressed that there was no universal attractant for both sexes. However, the most effective attractant for males was consistently Trimedlure. For females, Nu-lure with ammonium acetate gave the most satisfactory results. The combination of putrescine and ammonium acetate was also found appropriate, as it appears highly selective of C. capitata and remain efficient for more than 45 days. The authors noted that ammonium salts used in this study presented little interest as attractants.
