In a study of off-host stages, samples were taken from the top of the soil (to a maximum depth of 1 cm). The temperature is generally too hot for the larvae to develop on the surface of the sand and the deeper sand does not have enough oxygen. Rodentia: Cuniculus paca (lowland paca), Dasyprocta punctata (Central American agouti), Mus musculus (house mouse), Mus musculoides (Temminck's mouse), Rattus rattus (black rat), Rattus norvegicus (brown rat), Cavia porcellus (guinea pig), Cavia aperea (Brazilian guinea pig), Myoprocta acouchy (red acouchi), Hystrix (porcupine)įor the most part, the chigoe flea lives 2–5 cm below sand, an observation which helps explain its overall distribution.Primate: Homo sapiens (human), Papio sp.hybridus (southern long-nosed armadillo), Chaetophractus villosus (big hairy armadillo) Cingulata (armadillos): Dasypus novemcinctus (nine-banded armadillo), D.Carnivora: Canis familiaris (dog), Felis catus (cat), Panthera onca (jaguar). ![]() Artiodactyla: Bos taurus (cow), Sus domesticus (pig), Capra hircus (goat), Ovis aries (sheep), Dicotyles tajacu (peccary), Lama glama (llama), Lama vicugna (vicuña), Potamochoerus porcus (red river hog).Only one, Tunga trimamillata, has also been found infesting humans as well as cows, but only in Ecuador and Peru. Two dedicate themselves to armadillos, one to sloths, and another prefers only cattle. In contrast, most of the 13 species of Tungidae are only in the Western hemisphere, and each only targets 1-2 specific warm-blooded hosts. Second, it can infest a wide variety of hosts: at least 26 different species in over 5 different orders of mammals. ![]() ![]() First, it has a wide distribution: some 88 countries, in the Caribbean, Central and South America, tropical (sub-Saharan) Africa, and India. Tonga penetrans is unusual for the 13 known species of the genus Tunga. penetrans, as only the adults feed on mammals, and the mature female remains in the host for the rest of her life. The adult and the larval forms both feed on other animals. Mites penetrate the skin and feed on skin cells that are broken down through an enzyme they secrete from their mouth, but they will then leave the host. However, the jigger is a type of flea (Order Siphonaptera). The colloquial name jigger may be confused with chigger, a parasitical mite. Depending on the exact site, this can cause sensations ranging from mild irritation to serious discomfort. As the flea's abdomen swells with eggs later in the cycle, the pressure from the swelling may press neighbouring nerves or blood vessels. During the first day or two of infestation, the host may feel an itching or irritation which then passes as the area around the flea calluses and becomes insensitive. While embedded under the stratum corneum layer of the skin, it may reach up to 1 cm across. penetrans is most recognizable in its parasite phase. Identification Tunga penetrans Jigger (sand flea) infested foot Synonyms for Tunga penetrans include Sarcopsylla penetrans, Pulex penetrates, and many others. Jiggers are native to Central and South America, and have been introduced to sub-Saharan Africa. Jiggers are often confused with chiggers, a type of mite. In its parasitic phase it has significant impact on its hosts, which include humans and certain other mammalian species. It is a parasitic insect found in most tropical and sub-tropical climates. Tunga penetrans is a species of flea also known as the jigger, jigger flea, chigoe, chigo, chigoe flea, chigo flea, nigua, niknik, sand flea, or burrowing flea. ![]()
