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: The Mediterranean fruit fly (Medfly) is one of the world's most economically damaging pests. It displays highly seasonal population dynamics, and the environmental conditions suitable for its abundance are not constant throughout the year in most places. An extensive literature search was performed to obtain the most comprehensive data on the historical and contemporary spatio-temporal occurrence of the pest globally. The database constructed contained 2328 unique geo-located entries on Medfly detection sites from 43 countries and nearly 500 unique localities, as well as information on hosts, life stages and capture method. Of these, 125 localities had information on the month when Medfly was recorded and these data were complemented by additional material found in comprehensive databases available online. Records from 1980 until present were used for medfly environmental niche modeling. Maximum Entropy Algorithm (MaxEnt) and a set of seasonally varying environmental covariates were used to predict the fundamental niche of the Medfly on a global scale. Three seasonal maps were also produced: January-April, May-August and September-December. Models performed significantly better than random achieving high accuracy scores, indicating a good discrimination of suitable versus unsuitable areas for the presence of the species.

    ABSTRACT: This work aims to evaluate the mass trapping technique based on the use of female food-attractant lure Tri-pack ® and the insect growth regulators lufenuron for the control of medfly in citrus field. These methods were used as alternative to chemical control with malathion spraying in Washington navel orange orchards in 2006 and 2007. The assessment of the mass trapping technique efficacy was based on adult Medfly population reduction expressed by weekly recording of male captures together with the assessment of fruit damage at harvest. Trials were conducted using a density of 20 trap/ha. Results indicated significant differences in male captures and fruit damage percentages between the two tested methods and the control (malathion spraying). Concerning adult males Medfly captures, reductions of 62.86% and 47.29% were achieved respectively for the mass trapping based on lufenuron and Tri-pack ® respectively in 2007. For fruit damage assessment, results showed reduction of 9.68% for the mass trapping based on lufenuron and 31.99% for the mass trapping based on Tri-pack ® compared to the control.

    ABSTRACT: The use of simple and economic traps with long lasting lure dispensers is key for implementation of mass trapping strategies against pestiferous fruit flies. Simplicity, cost, ease of assembly, storage and transportation were considered during evaluation of a folding conical trap for mass trapping the Mexican fruit fly, Anastrepha ludens. The application of deltamethrin to the lid of the trap resulted in a cost-effective treatment, which helped retain flies in dry traps for at least 10 wk. However, the conical trap design and the diam, type and disposition of entry-holes, negatively affected performance of the trap under laboratory conditions. High numbers of flies could escape the trap over a short period of time after their release into its interior, although most of them died after escaping because of the delayed effect of exposure to deltamethrin. Under field conditions, no significant differences were observed between orange and yellow traps in capturing either A. ludens or lacewings. In contrast, the folding conical trap model was significantly more efficient in capturing Mexican fruit flies when baited with CeraTrap® lure than when baited either with the conventional hydrolyzed protein or with BioLure®. CeraTrap® lure was also significantly more attractive to beneficial lacewings than the other 2 lures. These results indicated that additional studies on fly population suppression under field conditions will be necessary before deciding to use the folding conical trap as part of a mass trapping strategy to control the Mexican fruit fly.
