Evaluation of Traps and Lures for Mass Trapping of Mediterranean fruit fly in Citrus Groves

Abstract

[EN] Mass trapping has proven to be a powerful weapon in the control of Ceratitis capitata (Wiedemann), and its application in Mediterranean countries has currently increased notably as a control method. In this study, the efÞcacy of newly developed traps and dispensers of attractants were assessed with the aim of Þnding the best trap and set the lifetime of the dispensers, thus improving the total efÞcacy of mass trapping. EfÞcacy trials with six different types of traps and six different types of female dispensers were carried out. Moreover, the lifetime of three female dispensers, including a new attractant composition dispenser with n-methyl pyrrolidine, were studied. Results show signiÞcant differences among the trap types using female attractants, with an advantage of nearly 3 times more catches in best trap. Tested female dispensers showed no signiÞcant differences in efÞcacy between trimethylamine and putrescine attractants regard n-methyl pyrrolidine, however we observed differences in lifetime between dispensers. Thus, there are signiÞcant differences among different types of traps and dispensers in efÞcacy, and the appropriate selection of the trap and dispenser will improve the mass trapping results
