SUMMARY Severe diseases of pepper (Capsicum annuum) , tomato (Lycopersicon esculentum) , eggplant (Solanum melongena) and tomato eggplant (Solanum integrifolium) in West Africa were induced by pepper veinal mottle virus (PVMV). Five selected virus isolates were serologically similar and readily transmissible by aphids in the non‐persistent manner, but they differed in host range and/or symptoms induced in some susceptible species. One isolate from eggplant failed to infect pepper, Chenopodium quinoa and C. amaranticolor , and induced only local infections in tomato. An isolate from tomato failed to infect eggplant, and an isolate from tomato eggplant induced severe stunting in Physalis floridana. The type strain, like the isolate from tomato, failed to infect Nicotiana tabacum systemically, but each caused severe systemic leaf and stem necrosis in tomato. None of the isolates infected S. melongena cv. Long Purple, suggesting that PVMV might be controlled in this and perhaps other crop species by the use of immune or tolerant cultivars. All five isolates were serologically related to potato virus Y and some to six of 12 other potyviruses.
