Biology of aphid vectors of barley yellow dwarf virus and the effect of BYDV on aphids
1984
Gildow, F.E. (Pennsylvania State Univ., University Park (USA))
Only 18 species of aphids have been reported as having the ability to transmit barley yellow dwarf virus (BYDV). Some of these species are monoecious, feeding and completing their sexual life cycle on only one type of plant. Others are heteroecious and require more than one host to complete the sexual cycle. Physiological changes in host plants due to normal senescence, as well as abnormal physiology in response to injury or infection, influence aphid biology, behavior, reproductive potential and morphology. The results provide circumstantial evidence that nutritional similarities in nitrogen metabolism between senescing and BYDV-infected plant tissues may influence aphid morphology
