New Host Records

A number of cereals and other grasses were compared as hosts for different isolates of viruses causing Agropyron mosaic (AMV), wheat streak mosaic (WSMV), barley stripe mosaic (BSMV), ryegrass mosaic (RMV) and orchard grass mosaic (OMV). Lolium multiflorum L. was susceptible to all the viruses. The four varieties of wheat tested were highly susceptible to AMV, WSMV and BSMV, but not to RMV or OMV. Clintland oats was susceptible to WSMV, RMV and OMV but not to AMV or BSMV. Lolium perenne L. and Dactylis glomerata L. were infected by RMV and OMV only, Agropyron repens L. Beauv. by AMV only, and Setaria italica L. Beauv. by BSMV only. Brant and Husky barley were slightly susceptible to AMV, but seven other varieties appeared immune. Unusual host records include the infection of Setaria lutescens (Weigel) Hubb. and one plant of Agropyron smithii Rydb. with WSMV, and the infection of Agropyron intermedium (Host) Beauv. with BSMV. A list of differential hosts is proposed.

Selection Of

Walsh is the first cultivar of western wheatgrass(Agropyron smithii Rydb.) to be released in Canada. It was developed at the Agriculture Canada Research Station, Lethbridge, Alberta. The cultivar is an improved selection of the native species, which is adapted to heavy clay soils, is drought-tolerant, hardy, and creeping-rooted. The grass is noted for its tolerance to salinity and its ability to grow and yield well on spring-flooded clay sites.Key words: Western wheatgrass, Agropyron smithii, heavy clay, revegetation, creeping-rooted, spring-flood

The Difference

AbstractA study was conducted in Butte County of western South Dakota to determine the relationships between habitat characteristics and spatial and temporal changes in community structure of grasshoppers on mixed-grass rangeland. Detrended correspondence analysis (DCA) of 29 undisturbed grasshopper communities and correlation analysis of DCA axis values and habitat variables denned specific spatial gradients underlying the community structure of grasshoppers. Results indicated that grasshopper communities changed along a primary gradient of percentage of coverage of grasses, particularly Buchloe dactyloides (Nutt.) Engelm., and a secondary gradient of percentage composition of clay and sand in the soil.DCA of 24 grasshopper communities sampled in 1986 and 1987, multiple regression analysis, and factor analysis were used to determine the relationships between specific habitat characteristics and changes in communities of grasshoppers treated with either a nonselective insecticidal spray (malathion) or a selective insecticidal bait (bran bait with carbaryl). Results indicated that between-year change in community composition, or the difference between post-treatment communities in 1986 and 1987, was positively correlated with percentage of coverage of total grasses and forbs. Community malleability, defined as the tendency of a community to return to its predisturbed state, was greater in habitats with high coverages of Agropyron smithii Rydb. and Carex spp., low coverage of Bouteloua gracilis (H.B.K.) Lag. ex Steud., and low species richness of grasses. Our results emphasize the importance of habitat characteristics in structuring undisturbed grasshopper communities and in community change after perturbation with insecticides.
