Abstract

Fruit flies by infesting grafted mangoes cause considerable losses and loss of profit to the various actors range from producers to consumers. To control these pests, synthetic chemical insecticides use is generally the most common and first resort solution in all regions of Togo. But this method remains dangerous for human and environmental health. The objective of this study was to test the effecacy of Biofeed trap, an alternative solution that is environmentally friendly in comparison with a trap already used in the field (M3 traps based on food bait). Three orchards of about 1 ha for the 3 treatments (Biofeed trap, M3 trap and control) were chosen in each of the five regions of Togo. The traps were installed at the premature fruit maturity at a density of 25 traps / ha and were monitored every two weeks until the final harvest by sampling the mangoes for the assessment of the infestation rate and identification of fruits fly species. After setting traps and monitoring the infestations, Biofeed traps proved effective by reducing fruit fly damage by 73.60% nationally, while M3 traps by 39.94%. The orchards that benefited from these traps had low infestation rates that promissing a good harvest. Incubation of the mangoes harvested in the orchards have allowed to identify 4 genera of fruit flies (Bactrocera, Ceratitis, Dacus, Zeugodacus) and Bactrocera dorsalis is the most abundant species found on this economically important fruit.
