Global warming is one of the most important ecological problems today. It does and will severely affect ecosystems and disturb ecological balance. Climate parameters such as increased temperatures can have significant impacts on insect pests. Climate change can have the following consequences- the expantion of the geographical distribution of insects, the increase of their survival and number of generations, the change of synchronization between plants and pests, increased risk of infestation by alien invasive pests, increased incidence of insect-borne plant diseases, and decreased effectiveness of natural enemies. In addition, the harmful ecological, economic and human health consequences of foreign invasive species can threaten biodiversity in natural ecosystems and cause destruction in flora and fauna.

It was found that the number of Invasive alien insect species (Dendroctonus micans (Kugelann), Ips cembrae (Heer), Ips amitinus (Eichhoff), Ips dublicatus (Sahlberg) (Coleoptera: Curculionidae: Scolytinae), Cydalima perspectalis (Walker) (Lepidoptera: Crambidae), Ricania japonica (Walker) (Hemiptera: Ricaniidae), Halyomorpha halys (Hemiptera: Pentatomidae) and Anoplophora chinensis (Forster) (Coleoptera; Cerambycidae) of the Eastern Black Sea Region increases with the effect of global warming. It causes insects to develop rapidly and epidemics, which is a dangerous threat not only to agroforestry but also to urban areas.

As a result, climate change will require adaptive management strategies to cope with the changing status of pests. Modified integrated pest management tactics, monitoring of climate and pest populations, and use of modelling forecasting tools are recommended.
