1 Animal Ectoparasites & Disease Vectors
Fleas Lice Ticks/Mites Biting Flies

2 Biting Flies

3 Biting Flies - Life Cycle

4 Biting Flies - Life Cycle

5 Biting Flies - Life Cycle

6 Biting Flies - Life Cycle

7 Unsanitary areas! feces, garbage, filth, etc.
Biting Flies - Habitat Unsanitary areas! feces, garbage, filth, etc.

8 Mosquitos - Life Cycle

9 Mosquitos - Habitat

10 Flies: Animals Affected
Cattle Horses Sheep/Goats Dogs/cats People

11 Flies: Injury Invasive Myiasis Nuisance Infection Weight loss
Reduced weight gain Scratching Hair loss Lethargy Infection

12 Direct Injury - Myiasis

13 Flies: Injury Blood Loss/anemia Hide Damage Disease
Cattle grub/cysts- on back & sides Disease Encephalitis: WNV, JEE (horses) Bot fly (sheep/goat nostrils)

14 Lice Killing ~4 million during WWI, And up to 7 million during WWII!

15 Lice: Biology Live on the animal Collect with skin scrapings
More common in autumn & winter Chewing & sucking Spread by direct contact Affect: Poultry Cattle Sheep/goats

16 Lice - Life Cycle Adult Nymph Stages

17 Lice: Injury Nuisance Infection Weight loss Reduced weight gain
Reduced milk production Scratching Lesions Hair loss Lethargy Infection

18 Ticks and Mites

19 Tick/Mite Biology Hard & Soft Ticks
Soft ticks tend to remain in bedding/stable/den Hard ticks fall off into vegetation & quest for next host

20 Ticks and Mites - Life Cycle

21 Ticks/Mites - Injury Mange Caused by mites
Feed on skin surface & burrow under skin Nodules form in tunnels Causes intense itching

22 Ticks/Mites - Injury Nuisance Infection Blood Loss/anemia Disease:
Babesiosis Q fever Tick paralysis Tularemia Tick borne fever

23 Ticks and Mites - Habitat
Underbrush, tall grass, pathways, resting places, dens

24 Fleas

25 Fleas - Biology Live on the host or in burrow/den
Pupae can remain dormant until host detected Sticktight fleas remain attached for long periods of time Affects: All mammals & poultry (sticktight fleas)

26 Fleas - Life Cycle

27 Burrows, nesting, and bedding down areas
Fleas - Habitat Burrows, nesting, and bedding down areas

28 Fleas - Injury Nuisance Dermatitis Anemia Disease: Plague Tularemia

29 Prevention Sanitation Eliminate Standing Water (mosquitoes)
Open range vs feedlot Breeding areas: dirty, damp, feces/manure Eliminate brushy areas/animal burrows Eliminate Standing Water (mosquitoes) Avoid overcrowding Maintain healthy animals

30 Control Insecticide application: Timing of application
Rubs Ear tags Sprays Livestock Residual barrier Timing of application Retreatment may be needed when eggs hatch Fly traps
