Abstract

Host potential of some cultivated legumes for the pea leaf weevil, Sitona lineatus (Linnaeus) (Coleoptera: Curculionidae).

Abstract

Sitona lineatus (L.), which is primarly a pest of peas both in Europe and in North America, appears to have a slightly different range of alternative food-plants in the 2 continents. To determine the likely direction in which this species could spread over the USA from the pea-growing regions of southern British Columbia, Oregon, Washington and Idaho, the acceptability of legumes other than peas as food-plants was investigated in Idaho in 1975. From the results, it was concluded that lentil was not a food-plant of S. lineatus in Idaho (although it was in Europe), and that perennial legumes such as lucerne, red clover and white clover were not as acceptable as peas or broad beans (Vicia faba).
