Mango is the third most important fruit exported from Côte d’Ivoire. Despite its economic importance, mango production in Côte d’Ivoire is limited by damage caused by fruit flies (Diptera: Tephritidae); direct losses to the mango crop can reach 40-80%. A study was conducted in two commercial mango production zones (Kohitierie and Ferke) to evaluate the efficacy of Great® fruit fly bait (GFFB) a liquid hydrolyzed protein formulation in a bottle; in comparison with the fruit fly bait GF-120. Three farms (2 bait treatments and 1 untreated control) were selected from each of the two zones, with 4-10 ha plot sizes. GFFB (1.5L protein hydrolysate + 4,5L water) and GF-120 (1L bait + 5L water), were applied at 50ml/1m2 of tree canopy. Applications were repeated weekly for 8-10 weeks until the end of harvest, and traps were checked weekly for fruit fly catches. At harvest, 100 fruits per plot were collected and weighed, and incubated over a layer of sand. After 3-4 weeks, all puparia were collected from the sand and fruits were dissected to retrieve puparia remaining in the fruit. Puparia were held in petri dishes until fly emergence. Six species of fruit flies were identified, with Bactrocera dorsalis as the dominant species (>95%). GFFB provided 93.6% and 89.2% control at Kohitierie and Ferke respectively, compared with 84.4% and 82.3% with GF-120. As with GF-120, GFFB can therefore be recommended as a food bait for fruit flies in an IPM package in Côte d’Ivoire.
