The mischievous of insects is mostly about their preying on the cultivated plants. In order to identify a pest correctly, one has to have the ability to identify its key characteristics. These are placed all over the insects corpse. A pest can be described by hundreds or even thousands of 'keys' - depending on the kind or species - what proves how difficult and time-consuming the identification is. ANN (Artificial Neural Networks) can learn, are less sensible to incomplete incoming information, they are processing entered signals and give results in actual time. The above properties and the analysis during the research allow to make a conclusion that ANN may do the identification task similarly to a human being. Thanks to such identification process automation it could be possible to eliminate the objectivism factor.
