E.; Ohlenbusch, P. D. Larvae of whitelined sphinx [Hyles lineata (Fab.)] caused heavy defoliation and other injury to several species of range plants in a newly seeded stand of brome grass [Bromus inermis Leyss.] near Lakin, Kearny County, Kansas. Although larvae of this species are rather general feeders on broadleafed plants, they had a sequence of preference and completely ignored the brome grass. Species commonly eaten included prairie evening-primrose [Oenothera albicaulis (Pursh)] and spotted beebalm [Monarda punctata L.]. It is conjectured that feeding by whitelined sphinx larvae may sometimes influence the composition of range plant communities on the short grass prairie of the North American Great Plains.

L.; McArthur, E. D. We discovered that the midwinter monoterpenoid (volatile or essential oils) content of A. tridentata is under genetic control. We base this conclusion on the results of our study which demonstrated that some accessions of A. tridentata, grown under uniform conditions, contained significantly higher levels of monoterpenoids than others. The relationship between monoterpenoids, digestion, and palatability has not yet been conclusively demonstrated. If monoterpenoids interfere with digestion or have a negative impact on palatability, breeding and selection schemes can be developed to capitalize on the significant variation that exists among accessions of A. tridentata. Superior strains of A. tridentata could then be developed for use on mule deer winter ranges.

E. Total nonstructural carbohydrates (TNC) levels in the roots and root crowns of bluebunch wheatgrass (Agropyron spicatum) were analyzed throughout the 1974 growing season. Reserves in root crowns were consistently higher than those in roots, except for the November sample when reserves were similar. The low point in TNC reserves occurred during rapid spring growth when 29% of the vegetative growth was completed and the average leaf length was 13 cm. Highest levels were attained in the late boot stage when average leaf length was 30 cm and 67% of current vegetative growth was completed.
