title: External parasites of dairy cattle.
abstract: Insects such as stable flies, house flies, horn flies, face flies, mosquitoes, horse flies, deer flies, cattle grubs, and lice as well as ticks and mites are the major external parasites of dairy animals in the United States. These pests cause obvious discomfort to livestock and economic effects of heavy populations usually are discerned easily. However, research efforts to date have failed to establish reproducible losses caused by specific ectoparasites. Research efforts involving a multidisciplinary systems approach are necessary to provide the data needed to develop total dairy management programs.
