Attraction of Tsetse Fly to NG2G Traps Containing Different Biends of Odor Baits in Three Vegetation Types

Abstract

The relative effectiveness of different blends of acetone (450 mg/h), cow urine (858 mg/h) and octenol (1.5 mg/h) odor attractants for tsetse flies (Glossina Pallidipes) (Diptera:Glossinidae) was assessed using NG2 G traps located in three areas of different vegetation types in the Nechisar National Park, southern Ethiopia. Their effect on the catch size and age composition of G. pallidipes was determined. Results indicated that blends of acetone, cow urine and octenol, and blends of acetone and cow urine, were more attractive than blends of acetone and octenol, and blends of cow urine and octenol. Blends of cow urine and octenol were more attractive than blends of acetone and octenol. All blends attracted more females than males. Higher numbers of older flies were caught for all blends in each of the three vegetation types.
