Fine Structural Features of Sensory Systems in Ticks and Mites: Evolutionary and Ethological Aspectscari. The problem of the origin of sensilla in arthropods is discussed. In ticks and mites, the topography and number of olfactory sensilla depend on the taxonomic position of species and genera, and not on their ecological or behavioural peculiarities. Specialization of feeding behaviour leads to a

Morphophysiological Peculiarities of an Insect Pheromone Sensory System in Lepidopteran and Hymenoptm tests revealed high sensitivity of olfactory receptors to sexpheromone as peculiar only to males. Extraordinary sensitivity of males is provided not only by external morphology of their antennae but probably by a great number of cells specialized for the reception of this pheromone, too. Definite

Natural and Genetically Engineered Visual Pigments of the Fly modulations in light intensity. This then allows landing even on a white sheet of paper, or to detect females over quite a distance. Pecularities concern the optics as well as the neural connections between retina and the first optic ganglion, but also the visual pigments. Properties of the latter
