- Аннотация: Body size is one of the important parameters that determine the biology, morphology, and physiology of animals. Despite their diminutive body size, the smallest insects retain the general structure, functionality, and diversity of their sense organs. The main sense organs of insects are compound eyes and antennal sensilla, which have been studied in a wide range of taxa. The size of the antennae and the number of antennal sensilla decrease considerably with body size. The size reduction of compound eyes is accompanied by some quantitative and structural changes: a decrease in the number and size of the facets, strong compaction of cellular elements, and various morphological adaptations unique to different insect taxa. Our review consists of two parts and includes not only coverage of the available literature on scaling of the sense organs in insects, but also analysis of the basic quantitative data on the insect vision organs and antennal sensory systems. The first part presented herein includes the general characteristic of the sense organs and an overview of the effects of scaling on the insect compound eyes. A unique database has been created, including data on the number and size of the compound eye facets in 370 species from 16 orders of insects. Allometric analysis has shown that the number of ommatidia in the compound eye is positively correlated with body size and is considerably reduced in smaller insects. The corresponding numbers diff er by up to three orders of magnitude between larger and the smallest insects. The linear size parameters of the ommatidia are also correlated with the body size, the values differing by an order of magnitude. The complex morphology of composite sense organs seems to limit the size reduction of individual sensory units, so that optimization of the sensory apparatus in miniature insects is primarily accomplished by reducing the number of structural elements. Keywords: miniaturization, compound eyes, ommatidium
