background: dung beetles of coleoptera associated to undisturbed cattle droppings in pastures present great diver sity and abundance. dung beetles also play an important role for transmission of some helminthes to human and cat tle. this study was made to survey the biodiversity and abundance of these beetles in ardebil province, western iran. methods: according to the field study all beetles a...
Insecticide treatment of cattle is an important method of tsetse control. However, insecticides applied to cattle have been shown to contaminate dung. This has a significant impact on insects using the dung as a resource, e.g. dung beetles. This reduces the recycling of dung and has a negative impact on productivity of pasture. However, applications of insecticide restricted to only the legs an...

BACKGROUND African trypansomiases of humans and animals can be controlled by attacking the vectors, various species of tsetse fly. Treatment of cattle with pyrethroids to kill tsetse as they feed is the most cost-effective method. However, such treatments can contaminate cattle dung, thereby killing the fauna which disperse the dung and so play an important role in soil fertility. Hence there i...

The present study was conducted to assess effect of dung beetles function in the soil water infiltration performance on the part of rangeland of university of Sharekord in the form of a completely randomized design within one year. Therefore, the meshes consisted of both large and small size were used and filled with cattle, sheep and goat dung in six treatments (presence of dwellers, tunellers...
Pyrethroid insecticides are widely used to control ectoparasites of livestock, particularly ticks and biting flies. Their use in African livestock systems is increasing, driven by the need to increase productivity and local food security. However, insecticide residues present in the dung after treatment are toxic to dung-inhabiting insects. In a semiarid agricultural habitat in Botswana, dung b...
