“…It is well documented that I. ricinus and related spp. are associated with humidity and forested rather than afforested areas (Gilot & Perez‐Eid, 1998; Uspensky, 2002; Lindstrom & Jaenson, 2003), as indicated in the present results. The preference for xerophilic vegetation by D. marginatus and D. reticulatus (Nosek, 1972; Estrada‐Pena et al ., 1992) was also observed in Hungary.…”

In order to update the occurrence of hard tick species in Hungary, 3442 questing ticks were collected from the vegetation by the dragging/flagging method in 37 different places in the country, between March and June of 2007. Ixodes ricinus (L.) turned out to be ubiquitous. Dermacentor marginatus (Schulzer) was absent from sampling sites in the southwestern part of the country, but in most places was concomitant and contemporaneous with Dermacentor reticulatus (Fabricius). These two species, as well as I. ricinus, occurred up to an altitude of 900-1000 m a.s.l. Haemaphysalis inermis (Birula) and Haemaphysalis concinna (Koch) were not confined to any parts of the country, unlike Haemaphysalis punctata (Canestrini & Fanzago) which was found in only one region. The local prevalence of the latter species was also significantly lower than those of the former two in the same habitat (fringes of meadows, paths in forests). Dermacentor spp. and H. inermis were represented only by adults. In most species females were collected more frequently than males, except in H. concinna and H. punctata. Temporal differences between the peak activity of I. ricinus and Dermacentor spp. on dry pastures appeared to equalize on meadows in mountain forests, and a similar phenomenon was observed for the three Haemaphysalis spp. when collected along forest paths with fresh, green vegetation.

“…Two main groups of ticks were distinguished in our studies with respect to T LD 50 : small ticks (Ixodes, Haemaphysalis, R. sanguineus) and large ticks (Dermacentor, other Rhipicephalus, Hyalomma). The difference in the duration of the poisoning development between these groups is highly significant (po0:001) and it coincides with our ecological classification of tick genera in accordance with their adaptations to different habitats (Uspensky et al, 1999;Uspensky, 2002). Body mass of ticks determines the degree of their cuticular defense and the amount of their nutritional reserves allowing them to survive under unfavorable environmental conditions for a prolonged time.…”

“…The species R. sanguineus is known as a hunter tick (Labruna and Pereira 2001), although the ambush strategy cannot totally be dismissed (Uspensky 2002). Based on our results, we suggest that benefits R. sanguineus to avoid parasitizing resistant dogs, like beagles, and this avoidance is facilitated by perceiving and being repelled by volatile substances associated with such dogs.…”

“…To find a host, ticks can perceive volatile and nonvolatile substances liberated by it, or excretion products as feces and urine (Waladde and Rice 1982;Carroll 2000). R. sanguineus is a nidicolous species, meaning that it breeds in the immediate environment of the host and can actively hunt to obtain a blood meal, or even use the ambush strategy (Labruna and Pereira 2001;Uspensky 2002).…”

Differences in the behavior of Rhipicephalus sanguineus tested against resistant and susceptible dogs

et al. 2010

To ascertain whether brown dog tick Rhipicephalus sp. infests resistant (beagle) and susceptible (English cocker spaniel) dogs differently, five animals of each breed were maintained in a kennel whose walls were infested with 7,000 larvae, 320 nymphs, 80 males and 80 females, in 3 infestations, at 10-day intervals. Five times more ticks were found on cocker spaniels (498) than on beagles (96). Substances were collected by rubbing pieces of clean flannel on the dogs for 15 min and these were tested for arrestment and attractiveness of ticks. Three choices were offered: cocker extract vs. control; beagle extract vs. control, and cocker extract vs. beagle extract. When allowed to choose between substances rubbed from dogs and a control, more ticks were arrested by extracts from the cockers than from beagles. In the arrestment tests with only a choice between substances from dogs of each breed, more ticks were arrested by cocker substances. To test for attraction, capsules containing adsorbent were used and the tests were carried out in a Y-olfactometer. Fifteen males and 15 females were tested, for each treatment. In the olfactometer, the ticks were not attracted to the odor of either breed, however the odor of the Beagle was apparently repellent. These results indicate that R. sanguineus can use substances from the dogs to differentiate susceptible English Cocker Spaniels from resistant Beagles.
