The species Haemaphysalis inermis was found in March, April, May, September and October. This species was recorded by Z. Petrovié and Bordjoki (1955a) in the continental parts of Montenegro during May. Z. Petrovié et al. (1955b) marked this species as an autumn-winter species in the region of Klju. As regards Rhipicephalus bursa and Rhipicephalus sanguineus, we should stress their fifth and sixth place in terms of abundance (4.67% and 3.06%>, respectively) within the period 1989 through 1990. These species were found in the surveyed area from May to August and reached their maxima in June throughout the surveyed area. Therefore, we conclude that they are summer tick species, as has been suggested also by other authors (Z. Petrovic and Bordjoki 1955a, Z. Petrovió et al. 1955b, Z. Petrovió 1979). As for the sex ratio in Rhipicephalus bursa and Rhipicephalus sanguineus, males were more numerous in Rhipicephalus bursa, accounting for 3.17%> of the total number of collected ticks and 67.95%> within the species, in contrast to Rhipicephalus sanguineus which exhibited female prevalence (74.51%) within the species.

Milutinovié, M., Petrovié, Z., Bobié, B. és Pavlovié, L: Ökológiai vizsgálatok Nyugat-Szerbiában (Jugoszlávia) gyűjtött atkákon (Acari: Ixodidae) A szerzők Nyugat-Szerbiában 12 lelőhelyről begyűjtött atkákon végezték vizsgálataikat 1989 és 1990 között. Az Ixodidae csalaádba tartozó atkák közül nyolc fajt sikerült kimutatniuk. A kutatás kiterjedt a fajkompozíció, az abundancia, a populáció-dinamika és az ivararányok meghatározására. A hőmérsékletnek, a csapadéknak és a páratartalomnak az atkák populáció-dinamikájára gyakorolt hatását is monitorozták. REFERENCES Cvjetanovié, V.
