Introduction:
The three-host Dermacentor reticulatus tick transmits many pathogens, which are introduced into the host with saliva during feeding.
Material And Methods:
The aim of present study was to analyse the behaviour of males of this species on the host in homogeneous sex groups comprising 15 (group I) and 30 (group II) male specimens and in a mixed group composed of 15 males and 15 females (group III).
Results:
Although the dynamics of attachment of the males to host skin slightly differed between these three groups, there was no statistically significant difference in the duration of the attachment process. The duration of host attachment of the males in groups I, II, and III at 18±2°C and 50 ± 2% RH was 2.43 ± 2.46, 7.75 ± 11.85, and 9.07 ± 10.97 days, respectively. After 7-9-day feeding, the male engorgement weight (MEW) was similar, regardless of the size of the group and the presence or absence of females on the host. Tick males ingest a small amount of host blood. The value of MEW in the three groups did not differ statistically from the weight of unengorged specimens.
Conclusions:
The host feeding behaviour of D. reticulatus males and their effective feeding suggest that they may play a role in transmission of pathogens and non-pathogenic microorganisms with tick saliva during blood meal ingestion. Clinical and laboratory diagnostics of human and animal tick-borne diseases as well as epidemiological studies should consider the possibility of pathogen transmission by males of metastriata ticks, which feed on the host for several days.
Insights
Male Dermacentor reticulatus ticks exhibit consistent feeding behavior and weight gain, regardless of group size or sex composition. This suggests their potential role in transmitting pathogens during their multi-day feeding period.
Area of Science:
- Veterinary Entomology
- Parasitology
- Disease Ecology
Background:
- The three-host Dermacentor reticulatus tick is a known vector for various pathogens.
- Pathogen transmission occurs via tick saliva during the feeding process.
Purpose of the Study:
- To analyze the host-feeding behavior of Dermacentor reticulatus males.
- To compare male tick behavior in homogeneous (15 or 30 males) and mixed-sex (15 males, 15 females) groups.
Main Methods:
- Observing male tick behavior on a host in controlled group settings.
- Measuring host attachment duration and male engorgement weight (MEW).
- Conducting observations under specific temperature (18±2°C) and humidity (50 ± 2% RH) conditions.
Main Results:
- No statistically significant difference in host attachment duration was observed across the groups.
- Male engorgement weight (MEW) was similar among all groups after 7-9 days of feeding.
- MEW did not significantly differ from unengorged specimens, indicating minimal blood intake by males.
Conclusions:
- Dermacentor reticulatus males demonstrate effective feeding behavior on hosts.
- Their prolonged feeding suggests a potential role in the transmission of tick-borne pathogens and microorganisms.
- Epidemiological studies and diagnostics for tick-borne diseases should consider pathogen transmission by male ticks.
