“…Thus, although we have only recently discovered the presence of the newly invasive longhorn tick ( H. longicornis ) in Pennsylvania, we do not know whether it had been introduced previously. H. longicornis is a tick with a wide host range, potentially capable of harboring and transmitting multiple pathogens, may induced meat allergies, and may be capable of reproducing parthenogenically [50–52].…”

BackgroundTick-borne diseases have been increasing at the local, national, and global levels. Researchers studying ticks and tick-borne disease need a thorough knowledge of the pathogens, vectors, and epidemiology of disease spread. Three surveillance approaches are commonly used to provide insight into tick-borne disease risk: human disease case surveillance, active tick surveillance, and passive tick surveillance. Long-term passive surveillance can provide up-to-date data on the spatial variability and temporal dynamics of ectoparasite communities and shed light into the ecology of rarer tick species. We present a retrospective analysis on compiled data of ticks from Pennsylvania over the last 117 years.MethodsWe compiled data from ticks collected during tick surveillance research, and from citizen-based submissions to the Penn State University Department of Entomology (PSUEnt). Specimens were deposited at the PSUEnt arthropod collections that eventually became The Frost Entomological Museum. While most of the specimens were submitted by the public, a subset of the data were collected through active methods (flagging or dragging, or removal of ticks from wildlife). We analyzed all data from 1900-2017 for tick community composition, host associations, and spatio-temporal dynamics.ResultsIn total there were 4,491 submission lots consisting of 7,132 tick specimens. Twenty-four different species were identified, with the large proportion of submissions represented by five tick species. We observed a shift in tick community composition in which the dominant species of tick (Ixodes cookei) was overtaken in abundance by Dermacentor variabilis in the early 1990s, and then replaced in abundance by I. scapularis. We analyzed host data and identified overlaps in host range amongst tick species, suggesting potential hubs of pathogen transfer between different tick vectors and their reservoir hosts.ConclusionsWe highlight the importance of long-term passive tick surveillance in investigating the ecology of both common and rare tick species. Information on the geographic distribution, host-association, and seasonality of the tick community can help researchers and health-officials to identify high-risk areas.

“…In August 2017, H. longicornis was found in the United States for the first time in all three of its life stages, infecting an Icelandic sheep in Hunterdon County (New Jersey) that had not been transported or had any contact with foreign animals (55). The following year, this tick was found in seven other states along the Eastern US and Arkansas (56), and its presence was verified by reexamination of archived historical samples, confirming that H. longicornis was present in West Virginia in 2010 and New Jersey in 2013 (56).…”

16Nairobi Sheep Disease virus (NSDv) is a zoonotic and tick-borne disease that can cause over 90% mortality in small ruminants. NSDv has 17 historically circulated in East Africa and has recently emerged in the Asian continent. Despite efforts to control the disease, some regions, mostly 18 in warmer climates, persistently report disease outbreaks. Consequently, it is necessary to understand how environmental tolerances and factors

“…The Asian longhorned tick (Haemaphysalis longicornis) transmits numerous human pathogens and is a highly invasive tick species [1]. In the United States of America this species was reported for the first time in 2017 [2], although archival evidence suggests H. longicornis has been present in the USA since 2010 [3]. Currently, H. longicornis has been detected in 12 states: Arkansas, Connecticut, Delaware, Kentucky, Maryland, New Jersey, New York, North Carolina, Pennsylvania, Tennessee, Virginia and West Virginia [4,5].…”

The Asian longhorned tick (Haemaphysalis longicornis) was reported for the first time in the United States of America in 2017 and has now spread across 12 states. The potential of this invasive tick vector to transmit pathogens will be determined through its association to native hosts, such as the white-footed mouse (Peromyscus leucopus) which is the primary reservoir for the causative agent of Lyme disease (Borrelia burgdorferi). We placed larval H. longicornis on P. leucopus, 65% of the larvae moved off the host within a short period of time and none attached. In contrast, larval black-legged ticks (Ixodes scapularis) did not move from the site of placement. We then conducted a laboratory behavioural assay to quantify the interaction of H. longicornis with P. leucopus and other potential mammalian host species. H. longicornis larvae were less likely to enter the hair of P. leucopus and humans compared to the hair of domestic cats, domestic dogs, and white-tailed deer. Our study identifies a tick-host hair interaction behaviour, which can be quantified in a laboratory assay to predict tick-host associations and provides insights into how ticks select a host.
