| 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,... |
