Amblyomma Life Cycle
Ticks constitute the Suborder Ixodida, of the acarine Order Parasitiformes, and are exclusively parasitic. The Ixodida contain three families, the Ixodidae , Argasidae , and Nuttalliellidae. The specimens collected in our data are of the Amblyomma genus falling under the Ixodidae family. (Horak et al., 2002).
Amblyomma life cycle includes four stages: the egg, larva, nymph with only one nymphal instar, and adult. All ticks feed on blood during some or all stages in their lifetime because they are considered obligate ectoparasites. Furthermore, Amblyomma larvae attack hosts, feed, detach, and develop in sheltered microenvironments where they molt to nymphs. Similarly, nymphs will seek hosts, feed, drop, and molt to adults. After reaching adulthood, ticks will again seek for hosts to feed, and in the case of engorged Ixodid females, will leave the host to lay their eggs in a secured location.
Moreover, blood-feeding begins …show more content…
They are also of veterinary concern mostly because of the many microbial disease agents they can transmit to livestock, companion animals, and wildlife. The debilitating and sometimes fatal host reactions produced in domesticated livestock and companion animals as a result of the feeding activities of certain species adds to the impact of these ticks. Diseases associated with Amblyomma include but are not limited to: tularemia, ehrlichiosis, Rocky Mountain spotted fever (RMSF), and boutonneuse fever. Among the biological factors that contribute to the high vector potential of ticks are their persistent blood-sucking habit, longevity, high reproductive potential, relative freedom from natural enemies, and highly sclerotized bodies that protect them from environmental stresses (Sonenshine,

    Golden Rod Gall Fly Research Paper

    The Eurytoma Gigantea is an external parasite. The Eurytoma gigantea attacks after the gall has reached its full size. The wasp remains in the central chamber of the gall after consuming the larva in mid-August. While in the gall this wasp feeds on the plant matter (Abrahamson et al. 1989). The Female Eurytoma giantea is technically a different parasitoid. The female wasps inject eggs into to the gall when the gall is thinner than the length of the parasitoid. This parasitoid is limited to smaller galls. The other type of Eurytoma is the Eurytoma obtusiventris. The Eurytoma are an internal parasite most prevalent during the hatching of the gall maker’s eggs during the time when the eggs hatch and the larva bore through the stem. When the Eurytoma obtusiventris attacks the larva, it causes the larva to prematurely pupate, and then the parasitoid consumes the gall fly. The Eurytoma obtusiventris remains in the gall throughout the winter until it pupates in the spring (Malcom…

    Epidemiology of Rocky Mountain Spotted Fever

    RMSF can be a life-threatening disease that causes damage to the body’s blood vessels, tissues, and organs. Once the blood vessels are damaged, the body triggers an inflammatory response that causes a surge of microembolic clots to coagulate in the damaged blood vessels, leading to hypoxia and even death if not treated. According to Anikwe, Davis, and Waters (2013), “RMSF is a potentially lethal Gram-negative, tick-borne infection caused by the Rickettsia rickettsii bacteria that’s prevalent in South, North, and Central America” (p. 19). However, in the United States, sixty percent of new cases in 2012 were in Arkansas, Missouri, North Carolina, Oklahoma, and Tennessee (Anikwe et al., p. 19). In the aforementioned states, the incidence rates are around sixty-three cases per one million people every year.…

    Scaabies Research Paper

    Newly emerged impregnated females will crawl onto the uninfected person. The mite will hold onto the skin using suckers attached to the two most anterior pairs of legs. They will then burrow into the skin. Transmission may also occur via fomites (e.g., bedding or clothing). Sarcoptes scabei undergoes four stages in its life cycle; egg, larva, nymph and adult. Sarcoptic mites form definite burrows under the skin in which females deposit eggs. Females deposit eggs at 2 to 3 day intervals as they burrow through the skin. Eggs are oval and 0.1 to 0.15 mm in length. Incubation time for eggs is 3 to 8 days. After the eggs hatch, the mites migrate to the skin surface and molt. The larval stage, which emerges from the eggs, has only 3 pairs of legs. This form lasts 2 to 3 days. After larvae molt, the resulting nymphs have 4 pairs of legs. This form molts into slightly larger nymphs before molting into an adult. Larvae and nymphs may often be found in short burrows or hair follicles. They look similar to adults, only smaller. Adults are round, sac-like eyeless mites. Females are 0.3 to 0.4 mm long and 0.25 to 0.35 mm wide. Males are slightly more than half that size. Mating occurs on the skin surface. Afterward, the impregnated female will burrow into the skin and spend the remaining 2 months of her life in tunnels under the surface of the skin. Males are rarely seen. They make a temporary gallery in the skin before…

    Lyme Disease Research Paper

    Lyme disease is a bacterial disease that affects over 200,000 each year. It is caused by the bacteria Borrelia burgdorferi. It is transmitted through the bite of blacklegged ticks (deer ticks). These ticks are found in grassy and wooded areas. Female nymphal or young black-legged ticks carry and transmit the Lyme disease bacteria Borrelia burgdorferi the most. Common symptoms of Lyme disease are fever, muscle pain, joint pain, headache, fatigue, and a characteristic skin rash called Erythema migrans (EM rash). To prevent Lyme disease while in grassy or wooded areas you can use insect repellent, remove ticks promptly, and applying pesticides. If you do contract Lyme disease, it can be treated with the antibiotics Amoxicillin (Amoxil), Cefuroxime…

    Lyme disease is a relatively new, being first reported in 1975, in Old Lyme , Connecticut. It is caused by the bacterium Borrelia Burgdoferi, which can be carried by rats and dears. The transmitters of the disease are the black-legged ticks that bite these animals, get infected and afterwards bite people. According to www.ehealthmd.com, “the average deer carries 200 or more ticks at one time”. Approximately half of these ticks are infected with the Lyme disease bacteria. The risk of contracting the disease is higher for people who have pets and for those who do activities outside, such as hiking or gardening.…

    lyme disease

    Although contrary to popular belief Lyme disease is very easily prevented. The easiest way to do this is when outside where long clothing that covers up almost all of your skin. This makes it harder for ticks or any other insects carrying the disease to burrow into your skin and use it as a shelter. Another very easy prevention for Lyme Disease is to avoid areas that are known to have insects that carry this disease. The most common places to find these insects is rural or suburban areas. The most common time for ticks to come out are when it is an unusual warm day like 65 degrees in November. They are more likely to come out on these days because they realize that it is getting to cold for them to survive on their own so they have to find a warm shelter in order to survive. If you ever go into areas that is known to contain insects with lyme disease check yourself for ticks as soon as possible this will help prevent lyme disease. The most common areas where a tick will burrow in are the hollows of your knees, armpits, and groin areas. If you are unfortunate to find a tick on you remove it as soon as possible. Many people will try to just yank it out this is not a good way to do it because if you do this there is a chance that you will not get the whole tick and some parts will stay there and can still spread lyme disease. The proper way to remove ticks is to take a pair of tweezers and very gently remove it by its head. This will not leave any part of the body behind that can infect the area.…
