modeling the present and future geographic distribution of the lone star tick amblyomma americanum ixodida Ixodidae in the continental united states
American Journal of Tropical Medicine and Hygiene, 2015Co-Authors: Yuri P Springer, Catherine S Jarnevich, David T Barnett, Andrew J Monaghan, Rebecca J EisenAbstract:Abstract. The Lone star tick (Amblyomma americanum L.) is the primary vector for pathogens of significant public health importance in North America, yet relatively little is known about its current and potential future distribution. Building on a published summary of tick collection records, we used an ensemble modeling approach to predict the present-day and future distribution of climatically suitable habitat for establishment of the Lone star tick within the continental United States. Of the nine climatic predictor variables included in our five present-day models, average vapor pressure in July was by far the most important determinant of suitable habitat. The present-day ensemble model predicted an essentially contiguous distribution of suitable habitat extending to the Atlantic coast east of the 100th western meridian and south of the 40th northern parallel, but excluding a high elevation region associated with the Appalachian Mountains. Future ensemble predictions for 2061–2080 forecasted a stable western range limit, northward expansion of suitable habitat into the Upper Midwest and western Pennsylvania, and range contraction along portions of the Gulf coast and the lower Mississippi river valley. These findings are informative for raising awareness of A. americanum-transmitted pathogens in areas where the Lone Star tick has recently or may become established.

spatial distribution of counties in the continental united states with records of occurrence of amblyomma americanum ixodida Ixodidae
Journal of Medical Entomology, 2014Co-Authors: Lorenza Beati, Yuri P Springer, Lars Eisen, Angela M James, Rebecca J EisenAbstract:ABSTRACT In addition to being a major nuisance biter, the lone star tick, Amblyomma americanum (L.), is increasingly recognized as an important vector of pathogens affecting humans, domestic animals, and wildlife. Despite its notoriety, efforts have been lacking to define the spatial occurrence of A. americanum in the continental United States with precision beyond that conveyed in continental-scale distribution maps. Here we present a county-level distribution map for A. americanum generated by compiling collection records obtained from a search of the published literature and databases managed by the USDA, U.S. National Tick Collection, and Walter Reed Biosystematics Unit. Our decadal and cumulative maps, which visually summarize 18,121 collections made between 1898 and 2012, show that A. americanum is either established (≥six ticks or ≥two life stages) or reported (

Description of a new species of Ixodes Latreille, 1795 (Acari: Ixodidae) and redescription of I. priscicollaris Schulze, 1932, parasites of New Guinea rodents (Rodentia: Muridae)
Systematic Parasitology, 2018Co-Authors: Dmitry A. Apanaskevich, Howard E. LemonAbstract:Ixodes goliath n. sp. (Acari: Ixodidae), is described based on females collected from the eastern hyomys, Hyomys goliath (Milne-Edwards) (Rodentia: Muridae) from Papua New Guinea. Females of I. goliath n. sp. are similar to those of I. priscicollaris Schulze, 1932 but can be distinguished by the overall size, porose areas sculpture and shape of palpal segment I ventrally. For comparative purposes, the female of I. priscicollaris is redescribed. Studied females of I. priscicollaris were found on murid rodents and Phascogale sp. (Dasyuromorphia: Dasyuridae) from Indonesia (Papua Province) and Papua New Guinea.

the argasidae Ixodidae and nuttalliellidae acari ixodida of the world a list of valid species names
Zootaxa, 2010Co-Authors: Alberto A. Guglielmone, Dmitry A. Apanaskevich, Richard G Robbins, Ivan Gerard Horak, Trevor N Petney, Agustin Estradapena, Renfu Shao, Stephen C BarkerAbstract:This work is intended as a consensus list of valid tick names, following recent revisionary studies, wherein we recognize 896 species of ticks in 3 families. The Nuttalliellidae is monotypic, containing the single entity Nuttalliella namaqua. The Argasidae consists of 193 species, but there is widespread disagreement concerning the genera in this family, and fully 133 argasids will have to be further studied before any consensus can be reached on the issue of genus-level classification. The Ixodidae comprises 702 species in 14 genera: Amblyomma (130 species, of which 17 were formerly included in Aponomma, a genus that is still considered valid by some authors), Anomalohimalaya (3), Bothriocroton (7, all previously included in Aponomma), Cosmiomma (1), Cornupalpatum (1), Compluriscutula (1), Dermacentor (34, including the single member of the former genus Anocentor, which is still considered valid by some authors), Haemaphysalis (166), Hyalomma (27), Ixodes (243), Margaropus (3), Nosomma (2), Rhipicentor (2) and Rhipicephalus (82, including 5 species from the former genus Boophilus, which is still considered valid by some authors). We regard six names as invalid: Amblyomma laticaudae Warburton, 1933 is a synonym of Amblyomma nitidum Hirst & Hirst, 1910; Bothriocroton decorosum (Koch, 1867) is a synonym of B. undatum (Fabricius, 1775); Haemaphysalis vietnamensis Hoogstraal & Wilson, 1966 is a synonym of H. colasbelcouri (Santos Dias, 1958); Haemaphysalis xinjiangensis Teng, 1980 is a synonym of H. danieli C erný & Hoogstraal, 1977; Hyalomma erythraeum Tonelli-Rondelli, 1932 is a synonym of H. impeltatum Schulze and Schlottke, 1930 and Rhipicephalus hoogstraali Kolonin, 2009 was not described according to the rules of the International Code of Zoological Nomenclature.

discovery of haemaphysalis longicornis ixodida Ixodidae parasitizing a sheep in new jersey united states
Journal of Medical Entomology, 2018Co-Authors: Tadhgh Rainey, James L Occi, Richard G Robbins, Andrea EgiziAbstract:: We report the discovery of large numbers of Haemaphysalis longicornis Neumann (Ixodida: Ixodidae) infesting a sheep in Hunterdon County, New Jersey, United States. All life stages were found on the sheep, which had no history of travel outside the country. H. longicornis is native to East Asia, and there are invasive populations in Australia, New Zealand and several Pacific islands, where this tick is a major livestock pest. It is currently unknown whether the New Jersey collections represent a limited or established population, but because this species could present a significant threat to human and animal health in the United States, vigilance is encouraged.
