原始语种摘要: Leek (Allium porrum) has become one of the major leafy vegetable crops in Egypt and all over the world. Iris yellow spot virus (IYSV) was observed on leek plants in eight different governorates in Egypt, in fields near to onion fields. The symptoms in infected leek plants included yellowish or tan diamond-shaped or irregularly shaped lesions on leaves and flower stalks. Necrotic areas developed on leaves, and some plants had elongated brown lesions or brown flecks resembling thrips injury. Moreover, thrips larvae and adults feed with a punch-and-suck behavior that removes leaf chlorophyll, causing white to silver patches and streaks, which were observed on all infected plants. The plant samples were collected and subjected to ELISA test using IYSV polyantiserum. The results revealed that...
