Dung Beetle - Benefits and Uses

Benefits and Uses

Dung beetles play a remarkable role in agriculture. By burying and consuming dung, they improve nutrient recycling and soil structure. They also protect livestock, such as cattle, by removing the dung which, if left, could provide habitat for pests such as flies. Therefore, many countries have introduced the creature for the benefit of animal husbandry. In developing countries, the beetle is especially important as an adjunct for improving standards of hygiene. The American Institute of Biological Sciences reports that dung beetles save the United States cattle industry an estimated US$380 million annually through burying above-ground livestock feces.

In Australia, the Commonwealth Scientific and Industrial Research Organisation (CSIRO) commissioned the Australian Dung Beetle Project (1965-1985) which, led by Dr. George Bornemissza, sought to introduce species of dung beetles from South Africa and Europe. The successful introduction of 23 species was made, most notably Onthophagus gazella and Euoniticellus intermedius, which have resulted in the improvement of the quality and fertility of Australian cattle pastures, along with a reduction in the population of pestilent bush flies by around 90 percent.

An application has been made by Landcare Research to import up to 11 species of dung beetle into New Zealand. As well as improving pasture soils the Dung Beetle Release Strategy Group say that it result in a reduction in greenhouse gas emissions from the agricultural sector.

Like many other insects, the (dried) dung beetle, called qianglang (蜣蜋) in Chinese, is used in Chinese herbal medicine. It is recorded in the "Insect section" (蟲部) of the Compendium of Materia Medica, where it is recommended for the cure of 10 diseases.

In Isan, Northeastern Thailand, the local people famously eat many different kinds of insects including the dung beetle. There is an Isan song กุดจี่หายไปใหน "Where did the Dung Beetle go", which relates the replacement of water buffalo with the "metal" buffalo, which doesn't provide the dung needed for the dung beetle. Hence, the increasing rarity of the dung beetle in the agricultural region.
