| The effects of antiparasitic drug, ivermectin, on the dung-breeding flies were studied in laboratory and field experiments in Hokkaido, Japan. In two pour-on treatments (500μg/kg), ivermectin was excreted in dung for up to 14 and 21 days after treatment, with peaks at 3 days and 1 day, respectively. Dung from treated cattle prevented the larval development of Haematobia irritans and Neomyia cornicina up to 14 days and reduced the larval and pupal survival rates at 21 days after treatment. In the field experiment using emergence traps, the numbers of emerged flies from dung pats were 3,655 (18 families) in control dung and 2,234 (16 families) in treated dung. Especially, Musca bezzii, Ravinia striata, Sepsis duplicata, Sepsis thoracica, Sepsis cynipsea,... |

| Effects of the antiparasitic drug moxidectin were studied in laboratory and field experiments in Hokkaido, Japan by pour-on administrations (500 μg/kg) on a target pest Haematobia irritans Linnaeus, nontarget coprophagous flies represented by Neomyia cornicina (Fabricius), and the dung beetle Caccobius jessoensis Harold. The concentration of moxidectin excreted into cattle dung was maximum at 3 days post-treatment both in the first and second trials, and then it diminished. No moxidectin was detected on or after day 21 post-treatment in the first trial, and on or after day 28 post-treatment in the second trial. Larval development of H. irritans was hampered from 1 to 7 days post-treatment. No N. cornicina pupated in dung at days 1 and 3 post-treatment, and... |
