Analysis of Variability of Morphologic Characteristics with Alternative Variation in Imago of Taiga Tick in the Territory of the Irkutsk Region

Investigation of the spatial-temporal variability of characteristics with alternative variation in females of taiga tick from three district of the Irkutsk Region showed all samplings to be phenotypically heterogenous. Based on these results estimated was L.A.Zhivotovsky criterion of identity between separate imago collections. Similarity index for geographically remote populations was about 0.9. This index was higher in intrapopulational groups collected from one territory in different seasons. The elucidated variability creates the basis for selection of morphologic tags of vector transmitting capacity and ticks life cycle duration and other questions of their biology investigation which includes usage of collection materials accumulated previously.
