| Abstract: | This paper has proved mathematically that the prerequisite for mini-orhan- isms to be able to purify polluted environment is that the amount of pollutant should he limited. The prerequisite for the natural enemies to be able to control insect pest is that the increase of injurious insects is restrained by the density of the latter. |
