Intra-individual polymorphisms in the mitochondrial COI gene of tick-killing Ixodiphagus wasps parasitizing Haemaphysalis flava ticks.

Ixodid ticks are significant vectors of pathogens affecting both humans and animals. Biological control with natural enemies represents a sustainable tool for managing ticks. However, there is a substantial lack of knowledge about the natural enemies of ticks.

Amblyomma kappa sp. n. (Acari: Ixodidae), a new species of reptile tick from subtropical East Asia closely related to the Oriental turtle tick (Amblyomma geoemydae) from tropical Southeast Asia.

The correct delineation of tick species is critical for efforts aimed at safeguarding One Health. Historically, the Asian turtle tick (Amblyomma geoemydae sensu lato) has been regarded as a geographically widespread species across much of Asia. However, based on morphological and phylogenomic data, the subtropical lineage (from Japan, Taiwan, and parts of China) of A.

Habu vipers (Protobothrops flavoviridis) are an overlooked but important reservoir of the zoonotic tick Amblyomma testudinarium (Acari: Ixodidae) in subtropical Asia.

Subtropical Asia has a rich diversity of reptiles and ticks, though the role of reptiles in the sylvatic cycles of medically important ticks in the region is poorly known. Habu vipers (Protobothrops flavoviridis) are widespread and common in the Japanese subtropics but their role as hosts for ticks has not been carefully explored. For 15 months in 2023/24, habu vipers were screened for ticks and were found to be important hosts for immature stages of the tick Amblyomma testudinarium, with a 22 % infestation rate.

Ecology and phenology of the bat tick () (Acari: Argasidae).

Although 12 soft tick species (Argasidae) are native to Australia, the ecology of most is poorly known. parasitizes several insectivorous bat species and has been recorded on humans. Therefore, understanding its ecology is crucial for wildlife health management and public health preparedness.

Nation-wide surveillance of ticks (Acari: Ixodidae) on birds in Singapore.

Surveillance programs focused on bird ticks are often challenging owing to the difficulty in capturing and screening birds as well as the fact that ticks on avian hosts frequently occur at a low prevalence. Nonetheless, elucidating the diversity and host preferences of avian ticks is critical for understanding public health risks posed by both migratory and resident birds. The first nation-wide surveillance program of avian ticks was initiated to examine bird-tick interactions in Singapore, a key juncture along the East Asian-Australasian flyway.

Forensic parasitology: a new frontier in criminalistics.

Parasites are ubiquitous, diverse, and have close interactions with humans and other animals. Despite this, they have not garnered significant interest from forensic scientists, and their utility as indicators in criminal investigations has been largely overlooked. To foster the development of forensic parasitology we explore the utility of parasites as forensic indicators in five broad areas: (i) wildlife trafficking and exploitation, (ii) biological attacks, (iii) sex crimes, (iv) criminal neglect of humans and other animals, and (v) indicators of movement and travel.

Nation-wide surveillance of ticks (Acari: Argasidae) on bats (Chiroptera) in Singapore.

Bats and ticks are important sources of zoonotic pathogens. Therefore, understanding the diversity, distribution, and ecology of both groups is crucial for public health preparedness. Soft ticks (Argasidae) are a major group of ectoparasites commonly associated with bats.

Host, season, habitat and climatic factors as drivers of Asian rodent tick (Ixodes granulatus) (Acari: Ixodidae) occurrence and abundance in Southeast Asia.

The Asian rodent tick (Ixodes granulatus) occurs throughout much of Asia, it frequently bites humans, and zoonotic pathogens, such as Borrelia burgdorferi (sensu lato) and Rickettsia honei, have been detected within it. Unfortunately, the ecology of I. granulatus remains poorly known, including drivers of its abundance and the interaction ecology with its sylvatic hosts.

The East Indies reptile tick Amblyomma helvolum Koch, 1844 (Acari: Ixodidae), taxonomy, biology and new host records, including the first record of human infestation.

Amblyomma helvolum is a widespread, generalist ectoparasite of reptiles in the oriental region, and has the potential to become highly invasive should it be inadvertently introduced outside its native range through the exotic pet trade. All life stages of A. helvolum are re-characterised morphologically and the first examples of nanism (dwarfism) and gynandromorphy (male and female tissue in one animal) for the species are described.

Cencurut virus: A novel from Asian house shrews () in Singapore.

is a genus of viruses in the family , order with a segmented circular RNA genome. They typically infect birds and mammals and are primarily transmitted by ectoparasites such as ticks. Four of nine genogroups can infect humans, with Crimean-Congo hemorrhagic fever virus infections displaying case fatality rates up to 40%.

Human-biting ticks and zoonotic tick-borne pathogens in North Africa: diversity, distribution, and trans-Mediterranean public health challenges.

North Africa is home to more than 200 million people living across five developing economies (Egypt, Libya, Tunisia, Algeria, and Morocco) and two Spanish exclaves (Ceuta and Melilla), many of whom are impacted by ticks and tick-borne zoonoses. Populations in Europe are also increasingly vulnerable to North African ticks and tick-borne zoonoses due to a combination of climate change and the movement of ticks across the Mediterranean on migratory birds, human travellers, and trafficked wildlife. The human-biting ticks and tick-borne zoonoses in North Africa are reviewed along with their distribution in the region.

The Asian turtle tick Amblyomma geoemydae Cantor, 1847 (Acari: Ixodidae) in the Philippines: first confirmed local host and locality with a complete host index.

Amblyomma geoemydae is an oriental tick species primarily associated with turtles and tortoises but also sometimes reported from other vertebrates, including humans. Although A. geoemydae was first reported from the Philippines more than 70 years ago, it has not been reported since, and no local distributional or host data have been published.

Habitat impacts the abundance and network structure within tick (Acari: Ixodidae) communities on tropical small mammals.

Ticks of small mammals pose a significant risk to public health but these hazards are poorly understood in the tropics due to the paucity of information on the disease ecology of ticks in these regions. Mapping and quantifying the diversity of small mammal/tick networks and the effects of habitat on these medically important systems is key to disease prevention. Singapore represents a microcosm of much of tropical Asia as it has a diverse, though poorly studied, community of ticks and small mammals.

A checklist and key to the tick fauna (Acari: Ixodidae, Argasidae) of Pulau Tioman, Malaysia.

Pulau Tioman is a popular tourist island off the east coast of Peninsula Malaysia, known for its vast areas of intact vegetation. Six tick species have been recorded on the island but little is known about their local ecology or public health importance. To facilitate studies of the tick fauna of Pulau Tioman, a checklist of all species and host associations is presented with the first host records, from Pulau Tioman, of Amblyomma helvolum from the Asian water monitor (Varanus salvator) and Amblyomma varanense from the keeled rat snake (Ptyas carinata).

First record of the sea snake tick Amblyomma nitidum Hirst and Hirst, 1910 (Acari: Ixodidae) from Taiwan.

The sea snake tick (Amblyomma nitidum) is a host specialist of snakes in the genus Laticauda and is one of the few ticks which could be regarded as semi-marine. Yet despite the attention this species has received due to its bizarre ecology, its distribution remains poorly known as geographic records of its occurrence through the Asia-Pacific are highly fragmentary. For the first time this species is recorded from Taiwan based on specimens collected from the yellow-lipped sea krait (Laticauda colubrina).

The Australian giant fleas Macropsylla Rothschild, 1905 (Siphonaptera: Macropsyllidae: Macropsyllinae), their identification, evolution, ecology, and conservation biology.

Macropsylla Rothschild, 1905 is an endemic Australian flea genus represented by two species: M. hercules Rothschild, 1905 and M. novaehollandiae Hastriter, 2002.

First Report of Co-invasion by the Reptile Nematode Ozolaimus megatyphlon (Nematoda: Pharyngodonidae) with Invasive Green Iguanas (Iguana iguana) in the Asia-Pacific.

Purpose: Co-invasion of naïve ecosystems by non-native parasites is a serious threat to global biodiversity, though such events are difficult to detect early in the invasion process. Green iguanas (Iguana iguana) are an emerging invasive species and have colonised several countries in the Asia-Pacific. A survey was undertaken to determine whether parasites of the green iguana had co-invaded naïve ecosystems with their introduced host.

Saving the Manx Shearwater Flea Ceratophyllus (Emmareus) fionnus (Insecta: Siphonaptera): The Road to Developing a Recovery Plan for a Threatened Ectoparasite.

Purpose: The Manx shearwater flea Ceratophyllus (Emmareus) fionnus Usher, 1968 is a host-specific parasitic insect apparently restricted to the Isle of Rùm, off the west coast of Scotland. Although C. (E.

Tick-crocodilian interactions: a review, with the first record of tick (Acari: Ixodidae) infestation in the saltwater crocodile (Crocodylus porosus), and a concise host-parasite index.

Interactions between ticks and crocodilians (crocodiles, alligators, caiman, and gharials) are poorly studied but may have significant bearing on the ecology and health of these reptiles. The first record of tick infestation of the saltwater crocodile (Crocodylus porosus) is reported along with the first case of infestation by Amblyomma cordiferum on Cuvier's dwarf caiman (Paleosuchus palpebrosus). A review is also provided of tick-crocodilian interactions with a concise host-parasite index.

Utilizing ticks as forensic indicators in a livestock investigation.

Although forensic parasitology remains in its infancy compared with more developed fields like forensic entomology, parasites can be useful forensic indicators. We present the case of an individual who disobeyed animal health legislation and crossed animal quarantine boundaries and two state lines with a cattle tick (Rhipicephalus australis) infested horse. Following recognition of the infestation by animal health officers, the individual asserted that the infestation had occurred either during transport or upon arrival at the site of discovery, and that they had not contravened quarantine legislation.
