2 Polyphagous pests (brief information on morphology, distribution, biology, and harmfulness)


Over the past decade, the importance of polyphagous pests has been steadily growing. This trend is driven, in part, by global influences such as climate change, and in part by advancements in science and technology - particularly the widespread application of potent insecticides and herbicides - combined with evolving economic conditions across various regions of the country. These developments are taking place alongside substantial shifts in the agronomic systems used for cultivating cereal crops.

Moreover, long-term ecological processes, including changes in species development and succession within natural habitats, have also contributed to the rising economic relevance of pest species. Collectively, these factors have led to a greater prominence of harmful organisms that, in the past, were largely regulated by climatic conditions, agricultural practices, and socio-economic management strategies.
