This was done to assess whether a spray formulation of cypermethrin may affect dung beetles differently than previously tested pour-on formulations. Following three beetle generations for two weeks each, the experiment retrieved no significant differences in adult or larval survival, egg production, fecundity and fertility between the control and treatment group. These results demonstrated that the used spray formulation of cypermethrin is likely to be far less detrimental to dung beetles than previously tested pour-ons.10aantiparasiticide10acymiazol10acypermethrin10aDung beetles10aecotoxicological effect10aEuoniticellus intermedius10apyrethroid1 aKryger, U.1 aDeschodt, C.1 aDavis, A., L.1 aScholtz, Clarke, H.  uhttps://scarabnet.myspecies.info/effects-cattle-treatment-cypermethrincymiazol-spray-survival-and-reproduction-dung-beetle-species-eu01838nas a2200241   4500008004100000245014500041210006900186300001200255490000800267520096100275653001401236653002301250653002601273653001601299653002801315653001401343653002401357100001501381700001701396700002101413700002401434856013801458       2007                        eng d00aEffects of cattle treatment with a fluazuron pour-on on survival and reproduction of the dung beetle species Onthophagus gazella (Fabricius)0 aEffects of cattle treatment with a fluazuron pouron on survival   a380-3840 v1433 aWhile resistance against many other classes of acaricides has been described, products containing benzoylphenyl urea are currently still successfully used against the pesticide-resistant blue tick (Boophilus decoloratus) in South Africa. In order to assess any adverse impact of these tickicides on the important dung beetle (Coleoptera: Scarabaeidae) fauna, a bioassay was undertaken on the ecotoxicological effects of a fluazuron (benzoylphenyl urea) pour-on formulation (Acatak1) on the survival and reproduction of the African dung beetles species Onthophagus gazella (Fabricius). The experiment yielded no significant differences in adult or larval survival, egg production, fecundity and fertility between the control and treatment group following three beetle generations over. These results suggested that treatment of cattle with the fluazuron pour-on formulation Acatak1 was not detrimental to the selected dung beetle species in any notable way.10aAcaricide10aBenzoylphenyl urea10aBoophilus decoloratus10adung beetle10aecotoxicological effect10aFluazuron10aOnthophagus gazella1 aKryger, U.1 aDeschodt, C.1 aDavis, A., L.
