Ivermectin excreted in cattle dung after subcutaneous injection or pour-on treatment: concentrations and impact on dung fauna
Ivermectin excreted in dung voided 1–2 days after both treatments significantly reduced the number of dung inhabiting larvae of Aphodius spp. Expand
Treating cattle with ivermectin : effects on the fauna and decomposition of dung pats
Compared with other forest ecosystems located at the similar latitude, the carbon fixation of the old-growth forest was larger, likely due to its complicated structure within the canopy and the presence of young-growth regeneration and successional stands and showed that other than in carbon neutral, old- growth forests of Tianmu Mountain in subtropical China had a strong capability in carbon sequestration.

In vitro stress selection of nematophagous fungi for biocontrol of parasitic nematodes in ruminants.
Fungi of the genera Arthrobotrys and Duddingtonia reduced the development of Ostertagia ostertagi third stage larvae by approximately 75% and 96% respectively compared to the number of larvae that developed from fungus-free control pats. Expand
Life history characteristics of Lumbricus terrestris and effects of the veterinary antiparasitic compounds ivermectin and fenbendazole
It is unlikely that earthworm populations will be affected in the field following normal use of sustained-release boluses in cattle, and the matrix model points to adult survival rate and cocoon viability as the most important variables to be included in future ecotoxicological tests on L. terrestris.

The capacity of the fungus Duddingtonia flagrans to prevent strongyle infections in foals on pasture.
The number of larvae in cultures from group TF was significantly lower than that in TC, herbage infectivity was reduced to a very low level on the pasture grazed by horses fed fungi and number of infective strongyle larvae harvested from faecal cultures were determined. Expand
Biological control. Aspects of biological control--with special reference to arthropods, protozoans and helminths of domesticated animals.
Industry may become more interested in biological control considering the increasing problems with parasite resistance to drugs in combination with the increasing cost of developing new chemical products, and because of increasing public concern about chemical residues in animal products and in the environment. Expand
Biological control of Ostertagia ostertagi by feeding selected nematode-trapping fungi to calves.
Three nematode-trapping fungi were fed to Ostertagia ostertagi-infected calves to test their ability to destroy larvae of this parasite in faeces and consequently to reduce the transmission of infective larvae to herbage. Expand
Effects of ivermectin on two afrotropical dung beetles, Onthophagus gazella and Diastellopalpus quinquedens (Coleoptera: Scarabaeidae).
Subcutaneous injection of 0.2 mg kg-1 ivermectin to heifers negatively affected larvae of the afrotropical dung beetles, Diastellopalpus quinquedens and Onthophagus gazella, developing in the dung.Expand
Effect of the nematode-trapping fungus Duddingtonia flagrans on the free-living stages of horse parasitic nematodes: a pilot study.
D. flagrans survived passage through the horses alimentary tract to significantly reduce the number of developing larvae, resulting in low numbers of larvae on the herbage in all groups of horses. Expand
Growth rate and trapping efficacy of nematode-trapping fungi under constant and fluctuating temperatures
The general reduction observed in the number of nematode larvae due to fungal trapping was 18–25% and 48–80% for a constant and fluctuating 10 °C, 70–96% and 93–95% for an constant and a fluctuating 15  °C, and 63–98% and 0–25%, respectively. Expand
