Comparative efficacy of two fruit juice products as attractants for trapping oriental fruit fly, Bactrocera dorsalis (Diptera: Tephritidae)

Adult Female tephritid fruit flies require a protein food source for the development of reproductive organ and egg production.Catches of Bactrocera dorsalis (Hendel) in Lynfied trap bated with locally made orange juice and pineapple juice were compared in two different bush mango plantations in Nigeria for two years.Methyl eugenol a commercial parapheromone was used as a standard adult fruit fly attractant.Orange juice was a more effective attractant than pineapple juice in trapping adult B.dorsalis for the two years of study at both sites.However, there was no significant difference (p<0.05) in the number of trapped flies by orange and pineapple juices.Orange juice captured 10.69 % -20.82 % of total adult flies for 2016 and 2017 respectively while Pineapple juice trapped 6.37% -16.29% of total adult flies for 2016 and 2017 respectively.Methyl eugenol caught the highest numbers of flies ranging 63.67% to 84.17% for 2017 and 2017 respectively at both sites.Methyl eugenol trapped only male adult flies while fruit juices trapped both male and female adult flies.Orange juice and pineapple juices significantly (p<0.05)captured a higher number of flies than the control for the two years at both locations.The density of flies trapped by all the attractants in 2016 was higher than that of 2017 at both locations.
