	abstract = {Field and greenhouse experiments were conducted to determine effects of three paracoprid dung beetles, Copris ochus (Motschulsky), Copris tripartitus Waterhouse and Onthophagus lenzii Harold, on the growth of pasture herbage and physical characteristics of the underlying soil. Treatments consisted of beetles plus dung, dung only and controls with neither dung nor beetles present. In the field in 2001, higher herbage yields were obtained with O. lenzii >= C. ochus = C. tripartitus >= only dung = control after 5 months. The air permeability of soil at a depth of 10 cm was highest when C. ochus was present (0.56 cm h(-1)), and lowest in the control (0.38 cm h(-1)). However, no significant differences were found among treatments in air permeability at 20 cm. In 2002/2003, the presence of all three species of dung beetle together was associated with higher herbage yields and with higher percentage nitrogen content than the control. In the laboratory, the presence of C. ochus and C. tripartitus was found to increase significantly the total crude protein in grass shoots and total digestible nutrient, compared with the control. The digestibility, dry intake and relative feed value of perennial ryegrass were highest where feces had been buried by O. lenzii. Acid detergent fiber was low in all treatments. The data suggest that the tunneling of paracoprid beetles improves the physicochemical characteristics of soil and increases the feed value of herbage by mixing and incorporating organic matter into the soil.},

	abstract = {Fresh dung was collected from untreated cattle and cattle dosed with a spray-on formulation of high cis-cypermethrin and chlorpyrifos (2.1 g/cow), on days 1, 3, 5 and 7 post-treatment. The survival and reproduction of the dung beetle Copris tripartitus Waterhouse, when given this dung was assessed. Residues of high cis-cypermethrin and chlorpyrifos in dung collected I day after treatment were sufficient to inhibit oviposition by female C. tripartitus. However, there was no significant effect on egg-laying in dung collected at days 3, 5 or 7 days post-treatment. In a second generation of C. tripartitus, derived from beetles fed the dung from treated animals, residues in dung collected both 1 and 3 days after treatment were sufficient to inhibit oviposition, and residues in dung collected 1 day after treatment inhibited dung consumption by newly emerged adults of C. tripartitus. It is concluded that dung voided by cattle treated with a spray-on formulation of high cis-cypermethrin and chlorpyrifos have toxic lethal effects for 1 day post-treatment and sub-lethal toxic effects on ovarian condition and brood-ball production in dung voided at 1 and 3 days posttreatment. The potential ecotoxic effects of these compounds are discussed in terms of dung beetle activity and strategies for parasite control of cattle in the Korean environment. (c) 2006 Elsevier B.V.
