Slide1
The segmentation is not clear on the body. Larvae with 3 pairs of legs, nymph and adult with four. Classified on base of breathing spiracles. Generally divided into: 1. Ticks 2. Mites
C. Order:
Acari
(
Acarina
)
Slide22. Ixodidae (hard tick): Mouth parts protrude in the front, not under the body. In Iraq we have several genera and species. Most of which parasitize
cattle, sheep, goats, doges and
other carnivorous. They are vectors of protozoa (babasia), rickettsia (tick typhus), viruses (Arboviruses, RSSF= Russian summer spring fever), and spirochaetes (lyme disease).
Slide3Slide4IV. Class Insecta: Very important vectors. Three body regions,Three pairs of legs.Most insects are winged.Undergo metamorphoses.
Four important orders: 1. Order: Hemiptera (نصفية الاجنحه): A. Family: Cincidae: non vector, but annoying….. (Bed bug).Feeding bedbug
Slide52. Family:Reduviidae: vectors of chagas disease.Triatomine bug (assassin bug)
Slide62. Order: Anoplura (القمل الماص):Pediculusvector of epidemic typhus and relapsing fever.

Slide8The segmentation is not clear on the body. Larvae with 3 pairs of legs, nymph and adult with four. Classified on base of breathing spiracles. Generally divided into:
1. Ticks 2. Mites
C. Order: Acari (Acarina)
Slide9Ticks: Relatively large, Sac like abdomen. Feed on blood only.Vectors of bacteria (spirochets), rickettsia (typhus) and viruses (ARBO viruses). Feed on blood only.Mouth
parts with
hypostome, have two families:
Slide102. Ixodidae (hard tick): Mouth parts protrude in the front, not under the body. In Iraq we have several genera and species. Most of which parasitize
cattle, sheep, goats, doges and
other carnivorous. They are vectors of protozoa (babasia), rickettsia (tick typhus), viruses (Arboviruses, RSSF= Russian summer spring fever), and spirochaetes (lyme disease).
Slide11Slide12HARD TICKS
Slide13Slide14Ticks: Argasidae (soft tick): Orthodoros moubata, Tholozane,
.
Mouth parts not protruded forward, under body. Main vectors of endemic relapsing fever.
Slide15Mites
Slide16Mites: very small to microscopic. No hypostome, feed by different ways. Only one rickettsial disease is known to be transmitted by chigger mite. Mites can cause itching, inflammation and rash (scabies). There are eight families, many of which feed on plants and other feeds on poultry, mammals or man
