Abstract
A northern mixed-grass prairie was exposed to monthly median S02 concentrations of 73, 134, and 228 μg/m3 Total grasshopper density and the density of Melanoplus sanguinipes (F.) were significantly (P < 0.01) reduced by SO2 treatment on late-growing-season dates within each year of SO2 exposure. Grasshopper density tended to decrease with increasing SO2 concentration. Sulfur dioxide did not alter the relative proportions of M. sanguinipes in the total population.Keywords
