Available resistance in alfalfa (Medicago sativa L.) cultivars is currently inadequate to control the alfalfa weevil, Hypera postica (Gyllenha), or potato Ieafhopper, ErnpoascaJabae (Harris), the two most injurious arthropod pests of alfalfa in North America. Resistance to both insects has been documented in other Medicago species having erect, glandular hairs. These hairs have been transferred to alfalfa. A field trial in 1985 was to determine the effects of erect, glandular hairs and their exudates on forage quality of several perennial Medicagos. Glandular and eglandular plant populations were selected from each of the diploids, M. prostrata Jacq. and M. glandulosa David., …
