Birds are one of the most important hosts of juvenile development stages of ticks. The tick dominant species in R. Moldova is three-hosts tick Ixodes ricinus Uspenskaia (1978) reported that this tick species is a most common on birds .
The actuality of research in the field of parasite-host relationship between ticks and birds is clear. Ticks have the main role in transmission and storage of many causative agents of many different natural focal diseases: different types of rickettsia of spontaneous fevers, piroplasmoses and arboviruses. Representatives of such pathogens where found in ixodes ticks. In Moldova the monitoring of migratory birds for infection with tick and tick-borne pathogens was not carried out since 1985.
Materials and methods. The study was carried out from March to November 2012 in 2 sites - Botanical Garden (Chisinau city) and Durleshti forest (Durlesti city) in close proximity to residential areas. Altoghether, 84 birds were captured with the help of specialized catching webs. Birds were placed in bags made of thick fabric, right after birds were examined in the camp for the presence of ticks. Ticks were removed with the help of tweezers and preserved in 70% alcohol, after the examination birds were released without being harmed and without banding.
Results. For the presence of ixodes ticks were examined 84 specimens of 24 species of birds from 14 families: Turdus merula, Turdus philomelos, Luscinia luscinia , Dendrocopos syriacus, Dendrocopos major, Dendrocopos minor, Picus canus, Parus major, Cyanistes caeruleus, Garrulus glandarius, Pica pica, Fringílla coelebs, Coccothraustes coccothraustes, Fringílla coeleb, Carduelis Chloris, Sylvia atricapilla, Phylloscopus trochilus, Erithacus rubecula, Phoenicurus ochruros, Emberiza citronella, Passerdomesticus, Anthus trivialis, Lanius collurio, Sitta europaea, Oriolus oriolus, Sturnus vulgaris. Most numerous were blackbird and mavis, T. merula and T. philomelos. During the study, it was established that of the 24 species 8 species were infected with ticks. From 84 specimens of birds 16 instances were infected. From the 16 bird specimens were collected 42 ticks. During the work we have detected 2 species of ticks I. ricinus with 38 samples and Ixodes frontalis with 4 individuals. Hosts of immature phases were next species – T. philomelos, T. merula, S. vulgaris, P. major, L. luscinia, E. rubecula, A. trivialis. The highest infection rate was recorded in May, larvae appeared at the beginning of June.
