Dung burial activity and development of ivermectin exposed Diastellopalpus quinquedens in a field experiment

Abstract
The amount of cattle dung buried in the field by afrotropical dung beetles, mainly Diastellopalpus quinquedens Bates, was not affected by previous subcutaneous injection of the cattle with 0.2 mg kg − 1ivermectin. The numbers of D. quinquedens larvae developing in brood masses, however, were reduced; only 28% of the brood masses made of dung voided two days after treatment of the cattle contained live larvae. When the brood masses were made of dung excreted 8 and 16 days after treatment 90 and 94%, respectively, contained live larvae.
