Abstract Horn fly (Haematobia irritans) is a widespread external parasite of grazing cattle; and integration of alternative biological control of this pest could help reduce the risk of resistance to chemical control. The objective of this experiment was to determine skin reaction to horn fly load on grazing dairy cattle sprayed with a 20 % creosote bush (Larrea tridentata (DC.) Coville) leaf extracts solution. To evaluate skin reaction a 10-month heifer with six paired circles marked on her skin was used, five sprays at five-day interval were applied; response variables were any harmful effect on skin and hair. To evaluate horn fly load effects there were two treatments: spraying or not of a 20 % creosote bush leaf extract, with six and seven cows for the...
