Abstract
When a mineral block containing either 0.94, 0.12 or 0.01% methoprene was given free choice to cattle for the control of horn flies, Haematobia irritans (L.), the average daily intake of mineral was 68 g/animal. The resulting inhibition of development of horn flies in the field was 87%, but the bioassay data in the laboratory indicated better than 97% inhibition. The highest concentration tested (0.94%) also effectively controlled stable flies, Stomoxys calcitrans (L.).Keywords
