DEVELOPMENTAL BIOLOGY FORMULA: NEW STYLIZED CATEGORY TO REPRESENT THE MAIN PARAMETERS OF HELMINTH BIOLOGY AND ECOLOGY

Within the section of general helminthology, based on the diversity analysis of biological cycles of helminth development, and the objective availability of common algorithms in closely related species, a conceptual proposal has been developed to introduce a new stylized category, the Helminth Developmental Biology Formula (DBF), into theory and scientific practice. The new category, the DBF, is designed for a logically sound, stylized and concise presentation of essential elements of bioecological characteristics of helminths. Basic regulations for the formation of the formula structure have been developed. A number of indicative parameters are proposed which, in accordance with helminthological terminology and pictograms, form the informational basis of the helminth DBF category. The regulation algorithm is universal, and, taking into account the bioecology characteristics of helminths, it is applicable to the DBF formation for representatives from various zoological taxa. On the example of biological cycles of development of trematode Paramphistomum daubneyi Dinnik, 1962, cestode Spirometra erinacei-europaei (Rudolphi, 1819), nematode Avioserpens mosgovoyi Suprjaga, 1965, Acanthocephala Macracanthorhynchus hirudinaceus (Pallas, 1781), and Monogenea Diplozoon paradoxum Nordman, 1832, in a stylized format, the structure and information content of the category Helminth Developmental Biology Formula are presented. The field of practical use of the helminth DBF is the following: 1) scientific and methodological, educational and reference helminthological literature, as an additional subheading within the main Helminth Developmental Biology Section; 2) in computer databases of various thematic orientation, in scientific characterization of the main bioecological parameters of helminths, due to the need to present material in a concise format.
