The management of the Mediterranean fruit fly, Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) in Turkey is mainly through chemical control. In this study, the effectiveness of the integrated pest management (IPM), mass trapping and chemical control were compared in an orange orchard in Tarsus (Mersin) during 2015 and 2016. The IPM program was based on the use of the synthetic food attractant lure Biolure, paired with sanitation of infected fruits and chemical control if necessary. In mass trapping plots the female targeted attractant lure Biolure and the male targeted sex attractant lure Trimedlure were used. Chemical control was based on bait treatments with Spinosad. The efficiency of the applications was evaluated according to the rate of infected fruits during harvest. The highest number of flies was detected in the Control plot as 404 flies/trap/week in 2015 and in Chemical Control plot as 429 flies/trap/week in 2016. No statistical difference was found between the applications regarding the number of male flies weekly captured and number of infected fruits. However, it was determined that the ratio of infected fruits in the IPM plot was lower than that of other plots (1.57% in 2015 and 0.89% in 2016) at harvest, followed by Biolure, Trimedlure and Spinosad, respectively. It was concluded that IPM, which included the application of several methods, was the most effective control practice for C. capitata.

This work aims to evaluate the mass trapping technique based on the use of female foodattractant 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 Tripack ® compared to the control.
— The Mediterranean fruit fly (Medfly), Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), is one of the most important pests of citrus in Turkey. The objective of this study was to evaluate mass trapping for the control of Medfly in Satsuma mandarin in Hatay province of Turkey. The studies were conducted in 2011-2012 using eostrap® invaginada traps baited with % 95 Trimedlure impregnated in a polymeric plug-type dispenser. In the first year, 48 traps per 0.7 ha were placed in an experimental site from 1 st August to December. In the second year, 23 traps per 0.7 ha were placed in the same site from 14 August to December. After two years of the study, the population density of medfly varied in each of the sampling year. In the first year, a total of 8968 medfly adults were caught by traps. The largest mean of catches per trap were recorded. In the second year, a total of 1307 medfly adults were caught by traps. The largest mean of the catches per trap were recorded on 25 September (7.35), followed by 13 November (5.83), 6 November (5.52), 18 September (5.43) and 30 October (4.26), respectively. The percentages of damage rates of medfly observed in both years. The damage rates of Medfly were 10.91 and 8.56 % in 2011 and 2012, respectively. In conclusion, the population density of medfly on satsuma mandarin increased in September and October due to high temperature. The mass trapping was not enough to control medfly on satsuma mandarin. Therefore, the mass trapping should be used with pesticides to decrease the population density of medfly during September and October in Hatay province of Turkey.

To develop eco-friendly alternative control strategies for medfly, mass trapping trials were conducted in the central Morocco during the crop season 2016. Two control methods, mass trapping and the attract-and-kill technique were compared for the control of medfly on two peach varieties ('Rome Star' and 'Ryan Sun') in Sefou district. For mass trapping, 62 traps/1.23 ha of Magnet TM Med type baited with ammonium acetate, trimethylamine, putrescine and 0.01 g of deltamethrin were installed on both varieties. In plots testing the attract-and-kill technique, treatments with malathion in mixture with protein hydrolyzate were applied to straw tufts attached to branches of the same varieties whenever 1 fly was caught on a Trimedlure trap installed at the center of each plot. The results showed that the number of flies captured by mass trapping reached 508 and 489 adults on 'Rome Star' and 'Ryan Sun', respectively. The average number varied from 1 to 3 adults/trap/day, depending on the date of capture and the variety, and females accounted for 62-100% of total caught flies. In plots protected by the attract-and-kill technique, and taking into account the threshold adopted by the farm, 11 and 15 treatments were carried out respectively on the 'Ryan Sun' and 'Rome Star' varieties. Overall, infestation rates in plots did not exceed 0.3% before or at harvest with mass trapping versus 0.9% with the attract-and-kill technique. On fruit dropped on the ground, the infestation rate did not exceed 4% in mass trapping, compared to 11.5% in the chemically treated plots. Mass trapping was therefore proved to be an effective and eco-friendly tool for managing medfly on peach fruit.
Evaluation of Traps and Lures for Mass Trapping of Mediterranean Fruit Fly in Citrus Groves
Journal of Economic Entomology, 2008
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.
The spatial distribution of medfly Ceratitis capitata (Diptera: Tephritidae) adults captured in the traps was analyzed in citrus orchards where mass trapping was applied to control the pest, with the objective of understanding how the method works, to determine the factors which influence it and to suggest changes which could improve its efficacy. A network of traps for mass trapping was established in 31 citrus orchards In Ibiza Island, from 2006 to 2008. The traps were of the tephri-trap type and baited with Tripack as attractant; they were uniformly distributed at a density of 50 per hectare following the standard recommendations. All traps of the mass trapping arrangement were sampled at intervals of 30 to 45 days by counting all flies captured on each trap. In all, 110 samplings, with a mean of 102 traps per sampling, were observed. Our results show that the establishment of the network of traps causes a barrier effect, with a gradual and rather constant reduction in medfly cap...
Ethological control of the Mediterranean fruit fly Ceratitis capitata (Wied.)
2019
The Mediterranean fruit fly Ceratitis capitata (Diptera: Tephritidae) is a serious threat for the Bolivian fruit sector. Despite its importance, few efforts have focussed on the development of alternative techniques to broad spectrum pesticides, especially those that suppress the pest using odour-mediated behavior manipulation. In this thesis, I explored whether such odor-based control techniques, using locally available attractants and repellents, could be developed. In laboratory and field trials, ‘chicha’, a corn-based fermented beverage was more attractive than commercial baits to C. capitata. However, non-target insects constituted a large portion of the trap catches. A series of traps based on waste material were designed and tested in combination with chicha. One prototype was comparable in captures with the commercial Tephritrap, while at the same time being more selective. In parallel, laboratory screening followed by semi-field and field trials were used to evaluate the ef...

The mass trapping technique based on the use of the female-targeted attractant lure Tri-pack ® as an alternative to malathion bait-spraying (control treatment) was tested in two citrus orchards in the North of Tunisia against the Mediterranean fruit fly Ceratitis capitata during 2006 and 2007. Results of mass trapping trials in 2006 and 2007 indicated that adult males Medfly captures showed reductions respect to control of 37.62% and 40.2% respectively in mandarin orange variety (Citrus reticulata) orchard compared to 36.48% and 47.29% in Washington navel orange variety (Citrus sinensis) field. Fruit damage assessment showed significant differences between the mass trapping with Tripack ® and malathion bait-spraying techniques in the reduction of the percentage of fruit punctures. The percentage of punctured fruit at harvest was significantly different between the treated and the control field in 2006 and in 2007 in the mandarin orange orchard. Nevertheless, in the Washington navel orange orchard, the percentage of punctured fruit at harvest was significantly different between the treated and the control field only in 2006. Thus, results obtained from this study showed that the mass trapping technique based on the use of the female-targeted lure Tri-pack ® could be involved as an appropriate strategy for the control of the Medfly and is as effective as malathion bait spraying treatment without leaving pesticide residues on fruit.
