Most viruses that infect plants need an intermediary (vector) for their spread between plants. This book describes, for the main vector groups, the current state of knowledge of what happens to viruses in their passage through their vectors and what interactions within the vector determine whether or not they are passed on to new plants. This volume of Advances in Botanical Research brings together current research on virus-vector interactions, with chapters on aphids, fungi, whitefly, beetles, nematodes, thrips, leafhoppers, treehoppers, and planthoppers, and other vectors.
