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 efficacy of newly developed traps and dispensers of attractants were assessed with the aim of finding the best trap and set the lifetime of the dispensers, thus improving the total efficacy of mass trapping. Efficacy 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 significant 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 significant differences in efficacy between trimethylamine and putrescine attractants regard n-methyl pyrrolidine, however we observed differences in lifetime between dispensers. Thus, there are significant differences among different types of traps and dispensers in efficacy, and the appropriate selection of the trap and dispenser will improve the mass trapping results.

    • "Alternatives to these organophosphate insecticides are clearly needed. As an alternative to these insecticides, the attractand-kill technique of mass trapping is used in many countries including Spain and Greece (Navarro-Llopis et al. 2008). Although mass trapping reduced C. capitata adult numbers and fruit damage in Tunisian orchards (Hafsi et al. 2015), the high costs of traps and attractants are considered limiting factors (Navarro- Llopis et al. 2013).

    ABSTRACT: For control of the Mediterranean fruit fly Ceratitis capitata (Diptera: Tephritidae), the attract-and-kill or attracticide technique is an alternative to the spraying of traditional organophosphate pesticides. In this study, the effectiveness of Ceranock and AAL&K attract-and-kill bait stations was assessed for control of C. capitata in Tunisian peach (Prunus persica) orchards. Our results showed that, in orchards with early-ripening varieties, the numbers of C. capitata males and fruit damage were significantly lower in plots treated with Ceranock and AAL&K bait stations than in plots treated with conventional organophosphate and pyrethroid insecticides. In addition, the abundances of non-target insects in the Chrysopidae, Coccinellidae and Miridae were significantly greater in plots treated with the bait stations than in plots treated with the conventional pesticides; that is, the use of attract-and-kill bait stations had fewer negative effects than the application of conventional pesticides on the biological diversity in Tunisian peach orchards. Overall, the results indicate that Ceranock and AAL&K attract-and-kill bait stations are useful alternatives for the control of C. capitata in Tunisian peach orchards planted with early-ripening varieties.

    • "In field trials satisfactory mass-trapping results were obtained by using 50 traps/ha; however, this technique is not effective enough to control high-density populations. Masstrapping is currently being applied in the Mediterranean Region; in Spain more than 30,000 ha of citrus groves are being treated with this technique [32]. "

    • "For both fruit flies, the efficacy of this technique depends on the type of trap and the attractant. Several studies have examined the effect of the design and color of traps on their efficacy for monitoring tephritids (Epsky et al., 1995; Cornelius et al.,1999; Navarro-Llopis et al., 2008), but only a few studies have associated pheromone release rate and insect catches (Landolt and Heath,1990; Dominguez-Ruiz et al., 2008; Suckling et al., 2008). Many studies have compared catches among several types or loads of dispensers for other insect families (Cork et al., 2006; Franklin and Gregoire, 2001; Kovanci et al., 2006), but only a few determined the optimal release rate of attractants in field trials (De Groot and Debarr, 1998; Cross et al., 2006; Vacas et al., 2009).

    ABSTRACT: Attractants and pheromones are commonly used in integrated pest management programs in crop systems. However, pheromone dispensers employed in monitoring traps and lure and kill devices are not usually well studied and attractants are released at uncontrolled rates leading to low treatment efficacies and misleading monitoring estimations. Fruit flies are pests of economic importance and monitoring is essential in order to program insecticidal treatments. Moreover, lure and kill techniques are being increasingly used, but the cost of these techniques depends on the number of required traps and, therefore, on the efficacy of the attractants. Ceratitis capitata and Bactrocera oleae are the two main fruit flies in Mediterranean countries, and the effect of different doses of trimedlure and spiroacetal on fly attraction has been studied. Results showed that a release rate over 1.28 mg/day of spiroacetal reduces B. oleae attraction and emission values over 2.4 mg of trimedlure per day did not increase C. capitata catches. Under the environmental conditions of our study, an optimum release rate for pheromone attraction in B. oleae was determined. Emission values over this optimum level reduced B. oleae attraction. However, when a parapheromone was used with C. capitata, a fruit fly of the same family, the optimum emission value was not found and higher quantities of parapheromone attracted the same number of flies. The saturation effect of high concentrations of pheromone and parapheromone is discussed.Highlights► An optimum pheromone release rate has been found in Bactrocer oleae ► This optimum does not exist in Ceratitis capitata parapheromone trimedlure. ► Optimum release rate of 1.28 mg/day of spiroacetal has been found for B. oleae. ► Release rate of trimedlure over 2.4 mg/day does not increase C. capitata catches. ► These findings are essential for monitoring and attract and kill techniques.
