Аннотация: A game theory model of insect population dynamics is proposed. In the simplest case-when a population can be in one of two states, in one of which the physiological processes in an individual are aimed at enhancing the growth and reproduction, and in the other the physiological processes are aimed at activating defense reactions of an individual-outbreaks of insect propagation occur when both the population and the habitat have a certain kind of memory, specifically, when the current states of the population and the habitat depend on their states at the preceding moment of time. The model proposed explains the well-known phenomenon of phase variation among insect individuals during the population outbreak. Copyright В© 2003 by MAIK "Nauka/ Interperiodica".

    Adaptation to flapping flight in different insects with complete transformation
/ D. L. Grodnitsky // Zoologicheskii Zhurnal. - 1996. - Vol. 75, Is. 5. - С. 699-700 . - ISSN 0044-5134

Аннотация: Types of flight systems in insects are described relying on the data on wing beat frequency, wing loading and other morphological and functional parameters. Each type is peculiar for one of the main endopterygote orders (Insecta: Scarabaeiformes-Oligoneoptera) which possesses the ability to fly. Origin of typical flight patterns in explained by particular features of morphology and mode of life. The wing apparatus of lacewings, scorpion flies and stone flies is characterized by the primitive features such as medium aspect ratio, low frequency and wing loading. Evolution of the flight system in beetles was strongly affected by the defensive function of thick and heavy external skeleton and thus resulted in adaptation to produce mainly lift. Dipterous flies aquired the most rapid and maneuverable flight due to particular morphological and kinematic features. Historical changes in structure and operation mode of hymenopteran wings were restricted to the necessity to transport additional loads while foraging due to social or semi-social life strategies of the species. Evolution of lepidopteran wings was determined by their heavy scale covering and the ability to regulate temperature inside thorax by means of either physiological or behavioural adaptations so that peculiar narrow-winged and broad-winged forms appeared.

    Evolution and functions of wings and their scale covering in butterflies and moths (Insecta: Papilionida = Lepidoptera)
/ D. L. Grodnitsky, M. V. Kozlov // Biologisches Zentralblatt. - 1991. - Vol. 110, Is. 3. - P199-206 . - ISSN 0006-3304

Кл.слова (ненормированные):
evolution -- flight -- Lepidoptera -- wing morphology

Аннотация: Examined wing morphology and flight kinematics in 53 species of moths and butterflies. The main pathways of evolution of flapping plane are described. The structure of wing scale covering was studies in 151 species. The most widely spread modifications of the covering are defined, and relationship of wing evolution to that of scale covering is discussed. The main function of scales is supposed to be thermoinsulatory. -from Authors

    ON WING VENATION OF CADDIS FLIES, MOTHS, AND BUTTERFLIES (INSECTA, PHRYGANEIDA, PAPILIONIDA)
[Текст] / D. L. GRODNITSKY // Zool. Zhurnal. - 1991. - Vol. 70, Is. 6. - С. 77-87. - Cited References: 41 . - 11. - ISSN 0044-5134

Аннотация: A comparative study of the wings internal and external morphology has been conducted in 39 species of Phryganeida and 57 species of Papilionida. A pronounced reduction of veins begins when the wing length decreases below 3 to 4 mm. The increase in the body size is associated with the development of jugal sclerotization into true veins, which are considered to be a differentiated part of the anal system. In the most primitive moths neither increase nor decrease of the absolute size leads to changes in the wing venation. The vein homology, wing design in the hypothetical ancestor of Amphiesmenoptera, as well as the differentiation of the venation in the wing evolution are discussed.
