The American Dog Tick occurs primarily in wooded, shrubby and long-grass areas. The glands begin to degenerate two days after engorgement. During this growth, their salivary glands begin to produce granular cells, which are believed to aid in digestion of blood. Females cayenne ticks consume blood from the host until they become engorged, growing to many times their original size. The combined effect of this transference of bodily fluids may lead to severe adverse reactions in the host, such as disease, paralysis, immune reactions, or death. Males preparing to mate may also excrete proteins into the host bloodstream which aid in fertilization of females during mating. This solution also allows water to be absorbed from the surrounding air and produces enzymes which aid in digestion after blood is ingested. The saliva contains enzymes which increase blood flow to the area of attachment and prevent clotting. At this point, any pathogens carried by the tick are released into the host. Upon locating a host, cayenne ticks attach themselves and burrow into the epidermis, releasing saliva. Hosts can be located tactilely (by touch) but also by using their setae, cayenne ticks also detect heat and increased levels of carbon dioxide of hosts. Although nymphs have little preference in host species, adults often search for equine hosts.Īs with most other ticks, Cayenne ticks “quest” to find their host, climbing grass or other vegetation and extend their front two legs to hitch a ride on a passer-by. Cayenne ticks feed on fewer of these host species as adults. Cayenne ticks feed on a number of species, including humans, dogs, cattle, horses, donkeys, rabbits, deer and birds. Most do not attach permanently to their host, but rather locate a new host for each feeding event. The complete cycle of egg to questing adult usually lasts about 6 months.Ĭayenne ticks feed exclusively on blood from vertebrate animals. Total time of development varies with temperature and availability of hosts. Larvae are most prevalent during April and May, though some may be found as late as October. They prefer to lay their eggs in areas with extensive vegetation. Fertilization occurs while cayenne ticks are present on a host.įemale cayenne ticks lay their eggs about a week following fertilization, generally in spring. This ensures that females have the blood meal they require to lay eggs. Male cayenne ticks produce pheromones in order to attract females to the host animal on which they are feeding. Males significantly outnumber females at all stages of development. The complete cycle of egg to questing adult usually takes about 6 months. ![]() Instead, nymphs feed on a wide range of available species, with hosts ranging from birds to humans.Īfter another blood meal, nymphs molt and enter the adult stage. However, nymphs are less restricted in their feeding behavior and do not specialize on grazing mammals. Larval, nymph, and adult cayenne ticks all engage in questing behavior, climbing on vegetation to locate host animals. At this stage, many features of an adult are present, though nymphs are much smaller than adults and are not yet capable of reproduction. Once larvae have fed, they molt and enter the nymph stage. Because cayenne ticks require a blood meal to reproduce, lifespan varies among individuals, particularly with regard to habitat resources. Reproduction usually occurs within the first year of life. After reproducing, female cayenne ticks die. ![]() Many species of ticks live for 2 to 4 years. After eggs hatch, the emerging six-legged larvae lack many of the structures apparent in adults but are capable of feeding. Females die immediately after egg-laying. Clutch sizes for hard-bodied ticks range from hundreds to 20,000 or more eggs per female. Females lay numerous eggs in a single egg-laying episode immediately after a large blood meal. Cayenne ticks have 3 life stages: larva, nymph, and adult. ![]()
