Soldier caste is the oldest altruistic caste in termites, highly specialized for defensive tasks. Therefore, a number of adaptations in anatomy and behaviour can be observed in soldier, lacking in other termite castes. The aim of this study was to verify the hypothesis that in disturbed groups the soldiers will prefer to stand by and defend the reproductives, the most valuable individuals. Therefore, I studied in two species of the genus Prorhinotermes (P. simplex and P. canalifrons) the ability of soldiers to discriminate neotenic reproductives and provide them with defence. In agreement with the initial hypothesis, the soldiers of both species prooved to be able of an instantaneous recognition of reproductives and remained close to them. In P. simplex, the neotenic female was the most attractive individual, while in P. canalifrons, neotenics of both sexes were equally attractive. The observed preference of reproductives appears to occur only with a certain age of the reproductives in incipient colonies, along with their sexual maturation. Caste specificity of cuticular lipids supports the presumption that the caste recognition is based on olphactoric cues in the cuticle of reproductives.

The work presents life and work of Vladimir Jan Amos Novak, it shows his main thoughts unified by the principle of sociogenesis and points at its inspiration in older traditions of german and russian biology. It also concerns his anthropology as related to the principle of sociogenesis and shows some peculiar Novak's contributions, mainly his opinions on progessive neotenization of man and evolutionary tedency for association. It grasps the principle of sociogenesis as a biological and also a political concept and therefore shows its very political consequences presented mainly on his social thoughts. The work also deals with the relations between eastern and western science on Novák's efforts to unify all sciences under one universal evolutionary framework regardless its geographical belonging. Throughout the work is Novak shown in the context of man-animal relations and the principle of sociogenesis as arising from myrmecological studies. There are therefore presented anthropological works of three important myrmecologists A. Forel, W.M. Wheeler and E.O. Wilson as inspired in the study of ants.
