A kiserletes rovarokologia jelentosege a novenyvedelmi allattanban



A kiserletes rovarokologia jelentosege a novenyvedelmi allattanban



NOVENYVEDELEM 42(8): 417-437



The paper begins with a description of the 20th century's history of science. The first half of the 20th century was characterized by a rapid development of quantum mechanics, which fundamentally changed the science physics thought so far static. The Author enlists the names of the scientists who played a role in the revolution of physics. He writes about the discovery of Watson and Crick (1953) which revolutionized the science of biology and gave birth to a new field of science: molecular biology. In the fifties of the 20th century the traditional biological disciplines took a second place owing to the Hungarian representatives of molecular biology. However, in the sixties the ecological catastrophes in various places of the Earth excited world-wide interest in the ecological disciplines, since molecular biology cannot solve the question of how to prevent these catastrophes. In Hungary the 1965 death of fish in Lake Balaton (500 t fish perised between May and July) aroused attention to the research of ecosystems. In Author's opinion the biological events occuring in the ecosystems can be better understood if the connection between the species of the system and the abiotic and biotic factors is known. Apart from this, the ecosystems have their own rules too.
