In a previous study Uroleucon ambrosiae (Thomas) complex and Aphis nerii Boyer de Fonscolombe respectively comprised 29% and < 2% of total aphids collected in water pan traps in St. Catherine, Jamaica. U. ambrosiae was also positively correlated with field spread of Tobacco etch virus (TEV) in hot pepper (Capsicum chinense Jacq.). Neither aphid was tested for its ability to transmit TEV. This investigation sought to determine whether they could vector TEV from pepper to pepper. Aphids were collected from their host plants in the field and placed on virus-free pepper plants (two aphids per seedling) for 24 hours. Aphids were then allowed to fast for one to two hours before allowed infective-feeding times of 15 to 60 seconds on TEV infected pepper leaves. They were then transferred to virus free pepper seedlings for inoculative feeding. After 24 hours any live aphids observed were physically removed and/or the plants sprayed with insecticide. Plants were observed for symptoms and presence of TEV was confirmed serologically. The tests were conducted three times for U. ambrosiae and once for A. nerii. Transmission rates for U. ambrosiae ranged from 16-46% while that for A. nerii was 83%. Additionally, when U. ambrosiae was transferred directly from its host to clean pepper seedlings there were infection rates of 3.6 to 33%. These have great implications for the management of TEV in pepper fields in Jamaica where U. ambrosiae and its weed host are common and where A. nerii is often collected from water traps.
