Description:
The rate of loss of crickets (Acheta domestica), with and without the presence of an adventitious predator, the gray-tailed vole (Microtus canicaudus), has been studied in Terrestrial Microcosm Chambers (TMC-II) treated with pine stakes impregnated with creosote, bis(tri-n-butyltin) oxide (TBTO), dieldrin (HEOD), pentachlorophenol (PCP) or a toluene solvent control. The first-order rate of cricket loss (-k) increased only for HEOD, to a maximum at 33 d post-treatment, with oscillations of about a 16-d period. This result infers a 'cricket-available' compartment of HEOD and/or metabolites with concentrations that must be greater than those measured in air, soil, water or plants and other biota.
