... 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. Herein, we present the first definitive locality repor ...

Abstract:
... Biological control based on entomopathogenic fungi is a promising option for controlling ticks on livestock. The objective of this study was to evaluate acaricidal effect of M. anisopliae (Metschnikoff) Sorokin (Ma14 strain) against R. microplus (Canestrini, 1887) on cattle. Thirty heifers naturally infested with R. microplus were divided into three groups of 10 each. One group was sprayed with Ma ...

Abstract:
... Members of the subgenus Eschatocephalus Frauenfeld, 1853 are highly specialized cave-dwelling ectoparasites of bats. We conducted a comprehensive field-based survey on bat ticks in Turkey and provided information about the phylogenetic placement of collected species. Sampling was carried out at 26 caves from 18 provinces around Turkey between 2019 and 2021. Eighty-one tick specimens collected from ...

Abstract:
... Historical records of five genera and 11 species of ticks were reported on domestic goats in the United States in literature published before 1951. In a field-based collection from random goats and pastures in eastern Oklahoma, we collected three species and three life stages of ticks. Ticks were collected throughout the year from domestic goats even when they were not collected in pastures. ...

Abstract:
... Figure 3 in this Journal of Medical Entomology article is central to the authors' warning about an exploding white-tailed deer population but conflicts in important aspects with the relevant deer research. Among other problems, it shows a 60% increase in the white-tailed deer density from 1500 to 2020 when the research consensus is that the population is about the same. It shows an exploding popul ...

Abstract:
... Tick bite induced α‐gal syndrome (AGS) following consumption of mammalian meat is a recently described intriguing disease occurring worldwide. Here we argue that AGS and delayed allergy in general is an adaptive defence method against cancer. Our hypothesis synthesizes two lines of supporting evidence. First, allergy has been shown to have direct anti‐cancer effects with unknown mechanism. Second, ...

Abstract:
... In the present study, the acaricide susceptibility status of Hyalomma marginatum in Morocco was investigated in the Rabat-Sale-Kenitra region using the Larval Packet Test. The overall LC₅₀ value for diazinon and amitraz was 115 ppm (95% CI: [104; 125]) and 22 ppm (95% CI: [21; 23]), respectively. The LC₅₀ values varied significantly between the nine sampled locations (P<0.001) ranging from 75 ppm ...

Abstract:
... BACKGROUND: Ixodes barkeri, a tick with a distinctive ventrolateral horn-like projection on palpal segment 1, was described in 2019 from two male ticks from the Wet Tropics of Far North Queensland, Australia. However, females lie at the core of the taxonomy and subgenus classification of Ixodes; hence, we sought specimens of female ticks, successfully recovering females, plus nymphs and larvae. Mi ...

Abstract:
... Disgust is a basic emotion which protects individuals from potential contamination. It is hypothesized that disgust evolved primarily as a mechanism against oral contamination or as a strategy against disease infections in general. We investigated visual attention to disgusting oral (rotten food) and non-oral (e.g., a tick) and control (e.g., a gull), non-disgusting stimuli using a touch-screen pa ...

Abstract:
... To identify ideal elements for the monitoring and prevention of tick-borne diseases (TBD), we analysed the surveillance systems in place in the Netherlands, Spain and Italy. We applied a semi-quantitative evaluation to identify outcomes and assess the degree of One Health implementation. Differences emerged in the surveillance initiatives, as well as the One Health scores. The Dutch surveillance i ...

Abstract:
... Information on the altitudinal distribution of the hard ticks Amblyomma aureolatum and Amblyomma ovale in Brazil is scarce and mainly limited to occasional records. In this study we report our evaluation of records on the altitudinal distribution of A. aureolatum and A. ovale collected from dogs and humans and directly from the environment (host-questing ticks), based on active or passive procedur ...

Abstract:
... Ticks use heat radiation emitted by warm-blooded animals to orient to potential hosts for blood-feeding. As sources of radiative heat produce convective heat as well, it is difficult to separate their effects of tick behavior. Here we study the behavior of the black-legged tick Ixodes scapularis and the lone star tick Amblyomma amercanum to sources of heat radiation representative of a human host ...

Abstract:
... Efficacy of the essential oil of Lippia sidoides to control the bovine tick Rhipicephalus (Boophilus) microplus was evaluated in tests on naturally infested cattle under field conditions. Twenty cattle were allocated to one of two groups (Control and Treated). Animals in the treated group were sprayed with three liters of 1 % L. sidoides solution (10,000 ppm) and efficacy was calculated from teleo ...

Abstract:
... Borrelia burgdorferi sensu lato (Bbsl) spirochetes thrive in sylvatic transmission cycles infecting vertebrates and their ticks. Rodents and ticks of the genus Ixodes are important hosts of these spirochetes globally. Although evidence suggests that Borrelia burgdorferi sensu stricto does not exist in South America, genospecies of the group (Bbsl) can be found in this region but have been poorly c ...

Abstract:
... In the south-central United States, several tick-borne diseases (TbDs) occur at or near their highest levels of incidence of anywhere in the U.S. The diversity of Rickettsia species found in Amblyomma americanum continues to be under-characterized in this region and throughout the U.S. and Canada where this tick species is expanding. One reason for this lack of knowledge about Rickettsia diversity ...

Abstract:
... Disease (re)emergence appears to be driven by biodiversity decline and environmental change. As a result, it is increasingly important to study host–pathogen interactions within the context of their ecology and evolution. The dilution effect is the concept that higher biodiversity decreases pathogen transmission. It has been observed especially in zoonotic vector‐borne pathosystems, yet evidence a ...

Abstract:
... Symbiosis with vitamin-provisioning microbes is essential for the nutrition of animals with some specialized feeding habits. While coevolution favors the interdependence between symbiotic partners, their associations are not necessarily stable: Recently acquired symbionts can replace ancestral symbionts. In this study, we demonstrate successful replacement by Francisella-like endosymbionts (-LE), ...

Abstract:
... The cattle tick Rhipicephalus microplus is an ectoparasite with high economic importance to bovine culture, mainly in tropical and subtropical regions. The resistance of the tick from the commercial acaricides has hindered its control, thus motivating the search for new strategies. The purpose of this study was to perform a critical review about the main molecular targets of R. microplus that are ...

Thermal constants were calculated based on the range of environmental conditions in the optimal distribution areas. The obtained constants of egg development and metamorphosis of larvae and nymphs are given for the taiga tick Ixodes persulcatus Sch., 1930 and the European forest tick I. ricinus L., ...

... Haemaphysalis qinghaiensis is an endemic species and mainly inhabiting in the northwestern plateau of China, which can transmit many zoonotic pathogens and cause great harm to animals. In this study, the complete mitochondrial genome (mitogenome) of H. qinghaiensis was assembled through the Illumina HiSeq platform. The mitogenome was 14,533 bp in length, consisting of 13 protein-coding genes (PCGs ...
