Application of phenetical analysis to study spatial organization of fleas (Siphonaptera) - plague vectors.

摘要

The spatial structure of fleas was considered using phenetic analysis. Differences in phenetic indices among 4 natural populations of Citellophilus tesquorum were consistent with the known subspecies differentiation. The greatest differences were found when the populations were of different subspecies and located far from each other. The least differences were revealed in geographically close populations of the same subspecies. Analysis of morphological variability of different characters in Amphalius runatus inhabiting the Altai natural plague focus in Siberia revealed 2 independent spatial groups in the territory under investigation.
