The species of genera Ixodes, Haemaphysalis, Rhipicephalus, Dermacentor and Hyalomma present the diversity of Ixodid ticks (Ixodidae) in Bosnia and Herzegovina (Omeragic 2011). For the territory of Bosnia and Herzegovina was reported three species of the genus Haemaphysalis: H. punctata, H. cholodkovskyi and H. inermis (Cankovic & Rozman 1980; Zuko 2013). However, the name H. cholodkovskyi (as H. cholodkowski in Cankovic & Rozman 1980 and H. cholodkowskyi /H. cholodokowskyi in Zuko 2013) has disappeared from modern taxonomic literature and has been considered as a synonym of H. sulcata (Guglielmone et al. 2014).

An investigation was conducted on the sample of primary school students in urban area with the aim of analyzing the anthropometric parameters between boys and girls entering 1st-9th grade. The main objective is to determine the frequency and causes of obesity in the population of school children with the intention of preventing the risks of developing the 'modern man' diseases (diabetes, hypertension, hypercholesterolemia, the development of metabolic syndromes, coronary heart disease, etc). The basic anthropometric parameters were measured: body weight and height, chest, waist and hips circumference, and from the obtained values the following were calculated: body mass index, ratio of waist circumference to body height and ratio of waist circumference to hips circumference. The comparison of the results according to age and sex of the pupils is expected to give the values that might answer some questions, such as: the degree of development and nutritional status of schoolchildren according to age and sex in relation to the environment in which they live, the annual increment of the measured parameters value, the differences between age and gender groups. Results were compared with parameters of growth and development of the children of same age in rural areas based on earlier research. The goal of the study is to confirm or reject the existence of a linear regression in correlation to some anthropometric parameters in relation to sex and age of the pupils from urban and rural areas, by means of the allometric method.
