Tick infestation
Tick infestation: parasitic hard and soft ticks (Ixodidae, Argasidae) on hosts or premises. Four life stages, blood meal each stage, up to 3-year cycles; major livestock pest and disease vector; controlled with acaricides and integrated management.
Tick paralysis
Tick paralysis is a rapidly reversible neurological condition caused by a neurotoxin from an engorged female tick during feeding, producing ascending flaccid paralysis within 2 to 6 days.
Tick removal and post-bite response
Tick removal and post-bite response covers pulling an attached tick with fine-tipped tweezers, cleaning the wound, and watching for rash or fever for up to 30 days.
Tick-borne disease
Tick-borne disease: illnesses caused by bacteria, viruses, protozoa, or parasites transmitted by infected tick bites, including Lyme disease, Rocky Mountain spotted fever, and alpha-gal syndrome; transmission occurs via tick saliva during feeding.
Tick-borne encephalitis
Tick-borne encephalitis (TBE), caused by tick-borne encephalitis virus (TBEV), a Flaviviridae Orthoflavivirus with European, Siberian, and Far Eastern subtypes, is an Ixodes tick-borne CNS infection endemic from Europe to Asia, also spread by unpasteurized dairy, preventable by inactivated vaccines such as TICOVAC.
Tick-borne encephalitis vaccine
Tick-borne encephalitis vaccine, also called FSME-IMMUN, TicoVac, or Encepur, an inactivated whole-virus vaccine against TBEV; three-dose schedule, over 87% seroconversion, Ticovac the only US-licensed product since 2021.
Ticks of domestic animals
Ticks of domestic animals are Ixodidae and Argasidae parasites of livestock, dogs, and cats that transmit babesiosis, theileriosis, and other diseases; controlled historically by arsenic dipping since 1893, now challenged by acaricide resistance and managed through integrated tick management.
Trombiculidae
Trombiculidae (chigger mites, red bugs): mite family whose parasitic larvae bite vertebrates via a stylostome, causing trombiculiasis; some Leptotrombidium species vector scrub typhus; 3,013 described species.
Trombiculosis
Trombiculosis (trombiculiasis, chigger dermatitis): pruritic skin inflammation from larval trombiculid mite feeding via a salivary stylostome; Leptotrombidium chiggers also transmit scrub typhus.
Trombidiidae
Trombidiidae, the true velvet mites or red velvet mites, is a family of about 300 species of large bright red predatory mites; larvae parasitize insects, adults eat insect eggs, and they are harmless to humans, unlike chiggers.
Tydeidae
Tydeidae (tydeid mites), family of cosmopolitan soft-bodied prostigmatan mites in Tydeoidea; 328 species in 30 genera, largest genus Brachytydeus; feed on plants, fungi, pollen; Orthotydeus lambi controls grape powdery mildew.
Typhlodromus
Typhlodromus Scheuten is a genus of predatory phytoseiid mites (type species T. pyri) in the tribe Typhlodromini, mostly Type III generalists used in conservation and augmentative biological control of spider and rust mites in orchards and vineyards.
Tyrophagus putrescentiae
Tyrophagus putrescentiae (Schrank, 1781), the mold, ham, or cheese mite, is an Acaridae storage mite pest of high-fat, high-protein foods, mushrooms, and cured hams; optimal development at 30°C and 80–90% RH, and a major storage mite allergen (Tyr p).
Uropodidae
Uropodidae, tortoise mites of the suborder Uropodina (Mesostigmata), are armored soil and compost mites whose deutonymphs disperse by phoresy on beetles using a secreted anal pedicel; about 2,300 Uropodina species are known worldwide.
Varroa
Varroa is a genus of parasitic mites, whose species Varroa destructor is the most damaging parasite of the western honey bee and a leading cause of colony losses worldwide.
Varroa mite control in honeybee colonies
Varroa mite control in honeybee colonies is the ongoing use of monitoring, chemical treatments, and husbandry tactics to keep parasitic Varroa destructor mites below levels that damage colonies.
Varroa sensitive hygiene
Varroa sensitive hygiene (VSH) is a heritable honey bee behavior, formerly called SMR, in which workers detect and remove brood cells infested by reproducing Varroa destructor mites, lowering infestation and also conferring chalkbrood resistance.
