Effect of Parapheromones on the Capture of Fruit Flies (Diptera: Tephritidae) in Burundi

Abstract

This study aimed to make an inventory of fruit fly species in Burundi, by use of parapheromones. The trapping by parapheromones is a method used to capture fruit fly species. Four types of parapheromones were used, namely, methyl eugenol, cuelure, terpinyl acetate and trimedlure. In total, 70,115 individuals were captured, of which, 68,728 individuals (or 98.02%) were fruit flies, while 1,387 individuals (1.98%) were non-fruit flies. The majority of Tephritidae has been captured by methyl eugenol with 62,538 individuals (90.97%), followed by cuelure with 3,621 individuals (5.27%). Terpinyl acetate and trimedlure have captured 1,900 and 669 individuals, respectively. The effectiveness of parapheromones has varied from one locality to another. In fact, methyl eugenol showed efficiency in the city of Bujumbura, Rumonge, Kigwena and Cibitoke located at an altitude between 780 m and 887 m; cuelure in Bubanza and Kayanza at an altitude between 1,101 m and 2,219 m; trimedlure and terpinyl acetate at Mwaro at an altitude of 1,640 m. From the point of view of abundance of species caught, Bactrocera dorsalis dominates with 62,349 individuals (90.72%), and it is in the Bujumbura city that this species has been captured in abundance.
