||Research was conducted in longleaf pine and old field habitats in the Coastal Plain of Mississippi. Prescribed fire was applied to treatment plots in February, and sampling for invertebrates was conducted during periods when bobwhite chicks would require increased protein availability, June to August. In old field type habitats, invertebrates were significantly more abundant one year post burn than in the unburned areas. In longleaf habitats, invertebrates were more abundant in areas that had experienced three growing seasons since burn as compared to areas in the first growing season since burn; however, most of this difference was due to changes in grasshopper abundance. This work also suggests that site fertility may influence the relationship between invertebrates and fire frequency.
