Haemaphysalis Luzonensis
''Haemaphysalis luzonensis'', the Luzon mountain glossy haemaphysalid, is an ixodid tick native to Luzon Island, Republic of the Philippines first circumscribed by entomologists Dr. Harry Hoogstraal and United States Air Force Maj. Dale Parrish in 1968. Its common name reflects its glossy and nearly apunctate, in comparison to other ''Haemaphysalis'' ticks, dorsal integument. Bionomics ''H''. ''luzonensis'' inhabits forests dominated by ''Dipterocarpus'' plants and Benguet pine at altitudes between 1,800 and 3,000 feet of the mountains in the central western part of the Sierra Madre Mountain range of Luzon Island. It parasitizes the Philippine deer and the Philippine warty pig in Nueva Ecija and Quezon Provinces of Luzon Island. Collection data suggest that both vertebrates are important hosts of adults and nymphs of this tick species. Males, females, and nymphs were documented to feed on their hosts between October and August, suggesting that they are active year-round. Th ...

Harry Hoogstraal
Harry Hoogstraal (born in Chicago, Illinois, February 24, 1917, died in Cairo, Egypt, on his 69th birthday, February 24, 1986) was an American entomologist and parasitologist. He was described as "the greatest authority on ticks and tickborne diseases who ever lived." The American Society of Tropical Medicine and Hygiene's ''Harry Hoogstraal Medal for Outstanding Achievement in Medical Entomology'' honors his contributions to science. Life and work Hoogstraal earned B.A. and M.S. degrees (1938 and 1942) from the University of Illinois at Chicago, before his training was interrupted by World War II to serve as an officer entomologist (1943–1946) in the United States Army. He later received Ph.D. (1959) and D.Sc. (1971) degrees from the London School of Hygiene and Tropical Medicine. As a master's degree candidate at the University of Illinois, he organized and led (1938–1941) four multi-disciplinary biological expeditions into the mountain and desert portions of western and s ...

Dipterocarpus
'' D. retusus'' in Köhler ''Dipterocarpus'' is a genus of flowering plants and the type genus of family Dipterocarpaceae. ''Dipterocarpus'' is the third-largest and most diverse genus among the Dipterocarpaceae. The species are well known for timber, but less acknowledged for use in traditional herbal medicine. The genus has about 70 species, occurring in South Asia and Southeast Asia, from Sri Lanka and India to the Philippines. It is an important component of dipterocarp forests. Its generic name comes from Greek and means "two-winged fruits". The greatest diversity of ''Dipterocarpus'' species occurs on Borneo, with many endemic to the island. The oldest fossil of the genus, and Dipterocarpaceae, is from the latest Cretaceous (Maastrichtian) Intertrappean Beds of India. Uses The genus is of considerable importance as timber trees, sold under the trade name Keruing, although not as important as ''Shorea'' species.

Dermacentor
''Dermacentor'' is a genus of ticks in the family Ixodidae, the hard ticks. The genus has a cosmopolitan distribution, with native species on all continents except Australia. Most occur in the Nearctic realm. Hosts of ''Dermacentor'' ticks include many large and small mammals, including horses, deer, cattle, lagomorphs, peccaries, porcupines, tapirs, desert bighorn sheep, and humans. The American dog tick (''D. variabilis'') is a member of the genus.

Amblyomma
''Amblyomma'' is a genus of hard ticks. Some are disease vectors, for example the Rocky Mountain spotted fever in Brazil or ehrlichiosis in the United States. This genus is the third largest in the family Ixodidae, with its species primarily occupying the torrid zones of all the continents. The centre of species diversity is on the American continent, where half of all the species occur. On this continent, ''Amblyomma'' species reach far beyond the torrid zone, up to the 40th parallel in the Northern Hemisphere, to the 50th parallel in the Southern Hemisphere, and even reaches the alpine zone of the Andes. They also occur in Eurasia, Africa and Australia. G. V.

Boophilus Microplus
The Asian blue tick (''Rhipicephalus'' (''Boophilus'') ''microplus'', ''Rhipicephalus microplus'', or ''Boophilus microplus'') is an economically important tick that parasitises a variety of livestock species especially cattle, on which it is the most economically significant ectoparasite in the world. It is known as the Australian cattle tick, southern cattle tick, Cuban tick, Madagascar blue tick, and Puerto Rican Texas fever tick. It is classified as a hard tick in the family Ixodidae. It is a small teardrop-shaped arachnid with a hardened plate called the scutum covering its head. Males are entirely covered in scutum on their backs with additional plates called festoons along their sides. The body can be brown or pale in nymphs and darkens as the tick matures.

Tick
Ticks (order Ixodida) are parasitic arachnids that are part of the mite superorder Parasitiformes. Adult ticks are approximately 3 to 5 mm in length depending on age, sex, species, and "fullness". Ticks are external parasites, living by feeding on the blood of mammals, birds, and sometimes reptiles and amphibians. The timing of the origin of ticks is uncertain, though the oldest known tick fossils are from the Cretaceous period, around 100 million years old. Ticks are widely distributed around the world, especially in warm, humid climates. Ticks belong to two major families, the Ixodidae or hard ticks, and the Argasidae, or soft ticks. ''Nuttalliella,'' a genus of tick from southern Africa is the only member of the family Nuttalliellidae, and represents the most primitive living lineage of ticks. Adults have ovoid/pear-shaped bodies (idiosomas) which become engorged with blood when they feed, and eight legs. Their cephalothorax and abdomen are completely fused. In addit ...

Host (biology)
In biology and medicine, a host is a larger organism that harbours a smaller organism; whether a parasite, parasitic, a mutualism (biology), mutualistic, or a commensalism, commensalist ''guest'' (symbiont). The guest is typically provided with nourishment and shelter. Examples include animals playing host to parasitic worms (e.g. nematodes), cell (biology), cells harbouring pathogenic (disease-causing) viruses, a Fabaceae, bean plant hosting mutualistic (helpful) Rhizobia, nitrogen-fixing bacteria. More specifically in botany, a host plant supplies nutrient, food resources to micropredators, which have an evolutionarily stable strategy, evolutionarily stable relationship with their hosts similar to ectoparasitism. The host range is the collection of hosts that an organism can use as a partner. Symbiosis Symbiosis spans a wide variety of possible relationships between organisms, differing in their permanence and their effects on the two parties. If one of the partners in an ass ...

Philippine Deer
The Philippine deer (''Rusa marianna''), also known as the Philippine sambar or Philippine brown deer, is a vulnerable deer species endemic to the Philippines. It was first described from introduced populations in the Mariana Islands, hence the specific name. Taxonomy ''Cervus mariannus'' was the scientific name proposed by Anselme Gaëtan Desmarest in 1822. It was subordinated to the genus ''Rusa''. Four subspecies are currently recognized: * ''R. m. marianna'' in Luzon biogeographic region * ''R. m. barandana'' in Mindoro * ''R. m. nigella'' in isolated upland areas of Mindanao * ''R. m. nigricans'' in lowland sites of Mindanao Characteristics The Philippine brown deer is relatively smaller than its relative, the sambar deer.
