Buffalo fly are a serious pest to cattle producers in Northern Australia. In recent cattle industry surveys, producers have nominated buffalo fly as the major parasite problem of cattle.
Increased resistance to the synthetic pyrethroid (SP) range of chemicals by the buffalo fly population has meant that the effectiveness of some chemicals is greatly reduced. Combined with this, the prevalence of buffalo fly has fluctuated further south over recent years. At the same time chemical residues are becoming increasingly important in all food markets.
