Grass, also known as hard ticks crawling child, a dog beans, tick, tick flat, is an important external parasites of dogs. Pathogenic parasites in the body of the dog ticks are blood-red fans head tick, Haemaphysalis two spines, Haemaphysalis longicornis, Dermacentor and Boophilus ticks and so on. Blood-red head fan tick, the male worm is about 2.7 ~ 3.3mm (including the false head), a width of 1.6 ~ 1.9mm. When the end of blood-sucking female body length 2.8 × 1.6mm (including the fake head). Three-host ticks, and its morphological characteristics are: Have anal sulcus, the shield plate no piebald, eyes, leave the first base triangle, were comma-shaped valve plate. Male ventral Have anal side. Second, Haemaphysalis spine, the male worm is about 1.96mm (including the false head), width 1.26mm; female end of the vampire When the body is about 2.38mm (including the false head), width of 1.40mm. Haemaphysalis longicornis, male worm is about 2.10 ~ 2.38mm (including the false head), a width of 1.29 ~ 1.57mm; When the end of blood-sucking female body length 2.52 ~ 300mm (including the false head), a width of 1.57 ~ 1.75mm. Second spine and Haemaphysalis Haemaphysalis longicornis is a three roundworm host of fresh blood. The morphological characteristics are anal sulcus, shield Plate no mottling, no eyes, should be very short, section II outreach, beyond the fake head group outside. Rectangular head fake, male Chitin little belly board. Dermacentor ticks, the male worm is about 6.2mm (including the false head), a width of 4.4mm; female body after satiation About 17mm (including the false head), a width of 11mm. Three host Farm. The morphological characteristics are anal sulcus, the shield plate There are silver-gray spotted, eyes, stubby limbs to be false the first base was a square, spiracular plate oval or comma-shaped. Ventral surface of male ticks little chitin plates. Boophilus, photo parasites about 1.9 ~ 2.4mm (including the false head), a width of 1.1 ~ 1.4mm, body Central widest; female body length when the end of the vampire 2.1 ~ 2.7mm (including the false head), a width of 1.1 ~ 1.5mm, Satiation after the parasite reached 12.5 × 7.8mm. This pest-free anal groove, no shield plate spotted, eyes, fake hexagonal head group Shape, valve plate oval. [Life cycle] is the incomplete metamorphosis of Ixodes arthropods, the development process, including egg, larva, if Four stages and adult worms. Most hard ticks on the animals mating, after mating the females suck blood meal, left-mail Host floor, climb crevices or under clods of static volt fixed, usually after 4 to 8 days until the blood digestion and egg development , It begins to lay eggs. Hard ticks lay eggs only once a lifetime, can produce more than dry or thousands of eggs, or even up to million or more. Eggs small, oval, brown. Usually after 2 to 3 weeks or a month or more hatched larvae. Larvae climb up places Main body of the vampire, after 2 to 7 days after blood meal, smoke, fell to the ground, through degenerate into nymphs. Hungry nymph Re-invasion of animals, parasitic blood-sucking, and then fell to the ground, dormant for several days to tens of days, degenerate into a sexually mature Female or male into a tick. After blood meal, smoking, body can be several times larger up to several times, the most significant female ticks can be 100 ~ 200 times; female ticks lay eggs l ~ 2 weeks after the death of the male ticks usually live about 1 month. With the species Ixodes Class there are differences in different areas of their lives, blood-red fans head tick, Haemaphysalis longicornis and Haemaphysalis two spines mainly living in the agricultural Areas and wilderness, activities, season 4 to 9 months; Dermacentor ticks live mainly in grassland, overwintering adults in early spring 2 Began to appear late or early in March, April for the busy period, in May decreased, Boophilus mainly live in rural areas, The activities of the season in North China for 4 to 11 months. [Symptoms] a small number of tick bites, most dogs do not show clinical symptoms, but the number increases, the disease Dog show itching, restlessness, often friction, grasping, and lick to try to get rid of biting insects, but such efforts However, has not often lead to local hemorrhage, edema, inflammation and keratinocyte hyperplasia. The average blood-sucking ticks each time a female 0.4ml, so when a large number of parasites, can cause anemia, weight loss And stunting. As parasites on the hind legs, can cause hind limb paralysis (nerve toxin); such as parasitic on the toe Q (which Peter only once), can cause claudication. Even if the tick capture, the limp will remain 1 to 3 days. In addition, the hard ticks or other parasitic and infectious diseases important medium, indirectly caused the dog sick. [Control] on the elimination of dog ticks body, you can hand to capture, or kerosene, petroleum jelly applied to oil Parasite location, so that after the removal of asphyxia. Pull out the tick, the tick should be made with the dog's skin into the body vertically upwards Stubbs, in order to avoid ticks fall off insect population control dogs, causing local inflammation. Caught ticks, should immediately kill it. In addition, 0.1% available phoxim, 0.05% coumaphos, trichlorfon 1%, 0.5% toxaphene, 0.5% Malathion or 0.05% of Diazinon and other liquid for spraying, dipping or washing, can kill the dog tick body Class. Eradication of ticks within the kennel, the kennel can tick insect life at the gap, with 0.75% DDT Spraying. According to Taiwan's "National Defense Medical Center," Department of Parasitology and Tropical Medicine, suffered the bite of hard ticks, if removed within 24 hours, the infection rate of Lyme disease about three into; if dragged over 48 hours, the infection rate of 100%. Taiwan, "Health Department" officials said this month only then Lyme disease added 15 for the fourth class statutory infectious disease, is currently not received any notification messages suspected cases; not rule out the hospital due to Lyme disease has been added to the clear Notifiable Diseases, negligence notification obligations. Lyme disease in the United States and Latin America and other countries ravaged serious, sometimes only sporadic cases in Taiwan, most of them imported.

[Life history]
Hard ticks are arthropods incomplete metamorphosis, the development process, including egg, larva, nymph and adult four stages. Most hard ticks on the animals mating, after mating the females suck blood meal, leave the host Post landing, climb crevices or under clods of static volt fixed, usually 4 to 8 days after blood digestion and egg development until after the start lay eggs. Hard ticks lay eggs only once a lifetime, can produce more than dry or thousands of eggs, or even up to million or more.

Eradication of ticks on dogs body, you can hand to capture, or kerosene, petroleum jelly applied to parasite location of oil, so after the removal of asphyxia. Pull out the tick, the tick should be made of the skin into the body of the dog pulling up vertically, so as not to tick off falls on insect population control dogs, causing local inflammation. Caught ticks, should immediately kill it. In addition, 0.1% available phoxim, 0.05% coumaphos, trichlorfon 1%, 0.5% toxaphene, malathion 0.5% or 0.05%, Diazinon, etc. liquid for spraying, dipping or washing, the body can kill ticks in dogs.
