The species that belong to sub-genera have therefore a certain number of proper or similar features in common. The status of sub-genus is attributed to each of those groups when scientifically relevant. Within a same genus, it is sometimes possible to differentiate (morphologically, and sometimes geographically or biologically) between one or several groups of species. Musca domestica curviforceps Sacca & Rivosecchi, 1957 POSITION SYSTÉMATIQUE DE LA MOUCHE DOMESTIQUE : Musca (Musca) domestica Linnaeus, 1758 Conversely, if we move toward the base of the pyramid, resemblance increases (for example, within the Hexapod (insect) class, the Diptera (flies) and Hymenoptera (bees) orders display higher resemblance with each other). If we move toward the top of the pyramid, the degree of resemblance between groups decreases (for example, in the Arthropod branch, animals that do not display much resemblance with one another are found, such as crabs, spiders, insects and centipedes). (Table 1).Įach group or sub-group gathers together animals or plants (insects in our case) that possess common, usually morphological, features. The classification of organisms relies on a hierarchical, pyramid-structured system that consists in creating groups and sub-groups that constitute taxonomical categories: classes, orders, families, genera, species, sub-species. The rules also apply to other organisms than insects. Naming organisms accurately (and only scientific names are accurate) even in the agricultural sector, is an indispensable and unavoidable prerequisite of any research, any experimentation and any study, in laboratory or on site.įor a better reading of this text, we thought it would be useful to give a reminder of some essential rules that apply to insect nomenclature and classification. ![]() Besides, scientific terms give access to targeted, accurate bibliographical research data that would not be accessible with only vague species indications. They allow traceability, language uniformity and universal accessibility when family, genus, species and sub-species names are expressed in scientific terms. the capacity for individuals belonging to a same population to interbreed and give birth to viable, fecund offspring in natural conditions.Īccuracy and rigour are needed more than ever. For scientists, the word “species” has a well-defined meaning: it is the basic unit (also called taxon) of systematic classification.Although the concept of “species” is currently interpreted in different ways by the scientific community, its main feature is inter-fecundity, i.e. Such approximate and therefore imprecise language highlights how difficult it is for the public to name or apprehend some “thing”, whether animal or plant, that more or less looks like some “thing” else. o name an animal or a plant species, people generally use the words « a kind of », a sort of », « a variety », « a race ». ![]() Moreover, their notion of what a species is or represents is quite vague. The general public is not familiar with scientific nomenclature, whether zoological or botanical. Insect classification, and thereby entomological nomenclature and more particularly insect scientific names have undergone many reorganisations and modifications over the last decades.
