Ivermectin (IVM) is widely used for parasite control in livestock the tropics. Residual IVM feces conserves its insecticide activity weeks and can harm dung beetle (DB) species. Attraction to of IVM-treated cattle was tested using DB species Onthophagus landolti (Harold) Canthon indigaceus chevrolati as models. Experiments were done under controlled laboratory conditions, semi-controlled field conditions uncontrolled conditions. Olfactometers trials. The treatment baited IVM-free feces, experimental treatments treated with 1 % (subcutaneous administration; single, 0.2 mg/kg bw dosage) collected at 5, 14, 21 28 days post-treatment. trial involved pitfall traps or from five Under (at post-treatment) attracted more O. C. i. individuals than (P < 0.05). same response occurred This clear attraction IVM-containing by studied highlights that incorrect use may pose a risk communities production systems.
