Moldenke, Walter G. Thies] A methodology using soil arthropods as a nontarget assay of chloropicrin fumigation against Phellinus root rot is described. Significant differences in seasonal abundances in control plot populations occurred for each of the 6 most common trophic guilds. Population densities were highest for springtails (Collembola) and oribatid mites (Cryptostigmata) during the late summer dry season; densities were highest in early spring for worms (Oligochaeta), mesostigmatid mites, and fungivorous macroarthropods. Biomass was highest for worms and mesostigmatid mites in spring, but fungivorous macroarthropods peaked in late summer. Springtails and oribatids were equivalent throughout the year measured as biomass; population peaks in dry summer are composed primarily of immatures. Nearly all individual species of springtails and oribatid mites had population densities that differed significantly by season; individual springtail abundances fluctuated with greater amplitudes than those of oribatids. Both springtails and oribatid mites increased significantly in population density and biomass from the 1st to the 2nd yr postharvest. Experiments using soil arthropods as bioindicators in forest soils beneath c1earcuttings should be monitored throughout the year to avoid confusing treatment effects with normal life history cycles. © 1996 Entomological Society of America Pest Management and Sampling nationallicence Phellinus weirii nationallicence bioindicators nationallicence chloropicrin nationallicence soil fauna nationallicence oribatid mites nationallicence springtails nationallicence Moldenke Andrew R.
