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 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.
Evaluation of insecticides and suitable trap containers for effective fruit fly catches
Indian Journal of Entomology
Fruit flies are quarantine pests and major impediments in horticultural production, domestic market, and export of fresh fruits and vegetables. Trapping with a lure is the best known method to monitor/ manage the fruit fly Bactrocera dorsalis populations. The fruit fly attraction and its mortality depend on the lure, type of killing agent, and design of the trap container. To make the trapping technology more robust, a study was conducted to find out the suitable killing agent amongst ten insecticides and the best trap design among the available six trap designs. The results revealed that emamectin benzoate 1.9EC was superior as killing agent with the maximum trap catches (648.75 to 1304.75 fruit flies/ trap) up to 12 weeks, followed by abamectin 1.9EC and profenophos 50EC. Among the trap designs, the CISH trap container was found to be superior (306.25 to 940.00 fruit flies/ trap/ week).
— 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.
Non-target Insects Captured in McPhail Traps Baited with Proteinaceous and Salts in Citrus Crop
Introduction: Traps baited with food attractants are commonly used for monitoring or mass trapping of fruit flies in many crops. The use of attractive food has a limitation in terms of catching non-target organisms. Attractives used alone or in combination may reduce the capture of non-target insects. Therefore, the mass trapping system in fruit crops can potentially impact negatively on the environment. Materials and Methods: A test was conducted in an orange orchard situated in the municipality of Mogi Mirim, state of São Paulo, Brazil. The following fruit fly lures were disposed into McPhail traps exposed to non-target insects for 55 days: 1) the liquid protein Cera trap®; 2) Cera trap® + Acetone; 3) Cera trap® + Ammonium phosphate dibasic (APD); 4) Cera trap® + Brazilian orange oilphase essence (BOE); 5) Cera trap® + Trimetylamine (TMA); 6) TMA; and 7) APD + BOE. Except Cera trap®, the other attractants were replaced weekly. Each treatment comprises five replications and each plot contained 35 orange trees. We compared effects of attractants and insects using 2-way ANOVA. Results: A large number of Diptera specimens were obtained in all attractants, corresponding to Original Research Article Galdino and Raga; JABB, 17(2): 1-9, 2018; Article no.JABB.39599 2 98.12% of the total capture. The majority of flies belonged to the families Drosophilidae, Muscidae and Calliphoridae. The numbers of Hymenoptera, Hemiptera, Lepidoptera, Neuroptera and Coleoptera insects were similar for each attractant. Conclusion: The findings of the present work showed no selectivity of Cera trap® even in combination with synthetic lures.

This study was conducted to evaluate the attractiveness of types, colors of traps traps and different attractants (Trimd, Femilure and Ceranock) to capture Mediterranean fruit fly Ceratitis capitata (Wied.) during the growing season of 2017 in private orchard at Al-Jadiriya in Baghdad. Three traps were used in the study (Jackson trap, local trap and McPhail trap); the results showed there is no significant effect among the types of traps on capturing of the flies with average of 10.33, 10.56 and 10.74 male / trap / week .The color of the tarps greatly influenced the numbers of the flies capturing in different traps; the results showed that the yellow traps were highest in attracting and catching the flies of 12.16 male / trap / week followed by the white color reaching 11.75 male / trap / week, and the green color (9.68 male / trap / week), While the red traps had lowest captured insect (9.06 male / trap / week). The results showed that yellow and white colors proved highly effect to capture the males in the trap, while there is no significant effect of the green and red colors on the number of males caught in the trap. Regarding the attractants, Trimd lure was the most effect in the term of male captured with average of 15.33 males / trap / week, followed by Femilure and Ceranock (11.33 and 8.33 insects / trap / week, respectively), the all traps used in the experiment are yellow and white with sexual attractant Trimdlure was an affective method to predict C. capitata and estimate population.

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.
Two bait-based techniques, Zonatrac Male Annihilation and Ceranock Attract and Kill, were used for the control of mixed populations of the Medfly Ceratitis capitata (Wiedemann) and peach fruit fly Bactrocera zonata (Saunders) on apricot and mango in Egypt. Treatments were carried out in an apricot orchard in Al-Beheira and later in a mango orchard in Al-Sharqiyah. Both techniques have proved to be successful in substantially reducing infestation on mango, where fruit damage assessment revealed infestation rates at 4.92% and 3.28% in two treatment plots, as opposed to 27.87% in an untreated control plot. The apricot trial witnessed a relatively high infestation rate in both treatment plots, as well as the control plot, due to an unexpectedly overwhelming Medfly population surpassing the application rate capacity. Apricot fruit damage assessment resulted in 51.92% and 42.72% infestation rates in the two treatment plots, and 44.55% infestation rate in the pesticide-treated control plot.
