The control of arthropod ectoparasites of livestock by systemically delivered chemicals was introduced in the 1950s. Their low cost, ease of use, and high level of efficacy ensured dependence upon them for ectoparasite control. However, current societal and scientific concerns regarding dependency upon chemicals have emphasised the need for the evaluation of environmentally safe alternatives for ectoparasite control. Immunological intervention for the control of ectoparasite populations, either through the selection of animals with resistant genotypes or vaccination, is consistent with principles of sustainable agriculture. Unlike the activity of chemicals, currently available ectoparasite vaccines do not induce a rapid knockdown of the parasite population and they do not protect the individual from parasitism. However, if these vaccines are used in an integrated pest-management programme, they have the potential to reduce parasite populations over successive generations and reduce or eliminate the need for chemical application.

D002418 Cattle Diseases Diseases of domestic cattle of the genus Bos. It includes diseases of cows, yaks, and zebus. Bovine Diseases,Bovine Disease,Cattle Disease,Disease, Bovine,Disease, Cattle,Diseases, Bovine,Diseases, Cattle
D004478 Ectoparasitic Infestations Infestations by PARASITES which live on, or burrow into, the surface of their host's EPIDERMIS. Most ectoparasites are ARTHROPODS. Ectoparasitic Infestation,Infestation, Ectoparasitic,Infestations, Ectoparasitic
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia
D001181 Arthropods Members of the phylum Arthropoda, composed of organisms having a hard, jointed exoskeleton and paired jointed legs. It includes the class INSECTS and the subclass ARACHNIDA, many species of which are important medically as parasites or as vectors of organisms capable of causing disease in man. Arthropoda,Arthropod
D013984 Tick Infestations Infestations with soft-bodied (Argasidae) or hard-bodied (Ixodidae) ticks. Infestation, Tick,Infestations, Tick,Tick Infestation
D013987 Ticks Blood-sucking acarid parasites of the order Ixodida comprising two families: the softbacked ticks (ARGASIDAE) and hardbacked ticks (IXODIDAE). Ticks are larger than their relatives, the MITES. They penetrate the skin of their host by means of highly specialized, hooked mouth parts and feed on its blood. Ticks attack all groups of terrestrial vertebrates. In humans they are responsible for many TICK-BORNE DISEASES, including the transmission of ROCKY MOUNTAIN SPOTTED FEVER; TULAREMIA; BABESIOSIS; AFRICAN SWINE FEVER; and RELAPSING FEVER.

D014612 Vaccines Suspensions of killed or attenuated microorganisms (bacteria, viruses, fungi, protozoa), antigenic proteins, synthetic constructs, or other bio-molecular derivatives, administered for the prevention, amelioration, or treatment of infectious and other diseases. Vaccine
