ABSTRACT 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.

    ABSTRACT: BACKGROUND: Two Ceratitis spp. coexist in the Island of La Réunion, Ceratitis rosa (Karsch) and C. capitata (Wiedemann). The effectiveness of the candidate systems based on attractants and traps to control both species was evaluated through comparative studies of trap types, attractants, insecticides and commercial complete systems. RESULTS: The Ceratitis spp. most captured in all trials was C. rosa. Captures of C. rosa and C. capitata were not significantly different when Maxitrap® or Tephri-trap® were used. Captures with the Easy-trap® were lower for both species. The BioLure® Med Fly lure showed higher catches of C. rosa than Ferag® CC D TM. The proportion of dead C. rosa did not differ significantly when deltamethrin or dichlorvos were used. There were no significant differences in capturing C. rosa and C. capitata between the commercial systems composed of the lure Ferag® CC D TM, the Maxitrap® and dichlorvos and the BioLure® Unipak, the Tephri-trap®, and dichlorvos. The Cera Trap® system performed less effectively. CONCLUSION: The most effective traps for the capture of C. rosa and C. capitata were Maxitrap® and Tephri-trap®; the most effective attractants were BioLure® Med Fly for C. rosa and BioLure® Med Fly, BioLure® Unipak and Ferag® CC D TM for C. capitata. However for both species the most effective commercial combinations of trap and attractant were Maxitrap® with Ferag® CC D TM and Tephri-trap® with BioLure® Unipak, both using dichlorvos. The insecticide deltamethrin showed good efficacy when used inside traps.

    ABSTRACT: Tests were conducted that evaluated efficacy of wax matrix bait stations for Ceratitis capitata (Wiedemann) adults in Guatemala. Bait stations were exposed to outdoor conditions to determine effect of weathering on longevity as indicated by bait station age. Results of laboratory tests found that bait stations with spinosad and ammonium acetate remained effective for at least 31 d compared with pesticide-free controls, although there was some loss of efficacy over time. Percentage mortality for bait station strips with 2% spinosad and 1% ammonium acetate decreased from 100 +/- 0.0% on day 0 to 70 +/- 7.1% after 31 d. Ammonia concentration had little effect on percentage mortality although there was some indication that ammonia concentration affected number of flies observed on the bait stations. Bait station strips (one per cage) were more effective than controls for 6-8 wk when tests were conducted in field cages (3 m diameter x 2 m), but only 2-3 wk when tests were conducted in large (2.5 m high and 6.0 m wide and 7.5 m long) field cages. Longevity was restored when multiple bait stations (3, 6, or 12) were deployed per cage. Bait stations containing methomyl were used for field tests of efficacy for wild flies. Dipped lure bait stations, which were made by coating two edges of commercial ammonium acetate and trimethylamine lures, killed six times more flies than corn cob bait stations dipped into a Nulure/malathion solution. They also killed more flies than pesticide-free controls for 8 wk.
