The fowl tick, also known as the “blue bug,” can be an importantpoultry parasite.The Of species, but only six of the more important species will be considered here. The Ixodid ticks are represented by a number The Argasid ticks are represented by two important species in Oklahoma, causing concernįor livestock and poultry producers. The majority of tick species are three-host Will drop from the host between each blood feeding life stage and usually finds a Tick will utilize one host for both larval and nymphal feeding. The eggs hatch and the larvaeĬrawl onto the vegetation and transfer to a suitable host as it passes. Ranging from several hundred to thousands, then dies. After the femaleĬompletes feeding, she will drop from the host and lay eggs on the ground in masses Each stage takes a blood meal, with the exception of eggs. To and remain on a single animal throughout its feeding stages (larvae, nymph andĪdult). As a one-host tick, the larva will attach itself Depending on the species, ticks are classified as ![]() The life cycle and seasonal activity for each tick species vary considerably and willīe discussed separately for each. Adding to the confusion of the names is the fact that theĬommon names of the tick species have “dog” and “wood” in their names, such as Americanĭog tick, brown dog tick and Rocky Mountain wood tick. These engorged females are often bluish-gray and can be These females are much larger, and therefore more visible than the other That look much different in appearance than unfed females, the males and all other Names are usually used in reference to the engorged (filled with blood) adult females Ticks because of their association with dogs, deer and the forest environment. The names “dog tick,” “deer tick and “wood tick” are commonly used to describe many Tick life stages are able to survive for a few years without finding a host and taking Most of the tick’s life is spent in the off-host environment seeking a host. Ticks have a very hard outer layer thatĮncloses all of the tick’s organs and allows the tick to withstand environmental stresses. Several days to weeks for the adult ticks. Soft ticks blood-feed quickly (within an hour). There are two main categories of ticks: the Argasidae (soft ticks) and Ixodidae (hard Protrude from the tick body and are often incorrectly called the head of the tick. Head is lacking, however, mouthparts of varying lengths (depending on the species) Ticks can be distinguishedįrom insects because their bodies are not divided into distinct segments. Ticks are more closely related to spiders than insects. Adults and nymphs have four legs,įigure 1: General life cycle of ticks. ![]() Larvae are sometimes called seed ticks and are slightly smaller Ticks have four “developmental” or life cycle stages known as the egg, larva, nymphĪnd adult (Figure 1). In animals, the loss of bloodĬan cause secondary anemia and sometimes death. ![]() Swelling, inflamed condition of the skin) on the host. Tick bites can cause dermatitis (an itching, Paralysis, toxicosis and allergic reactions.
