By mitigating the negative effects of urbanization, trees contribute significantly to the well-being of urban residents. Ecosystem services delivered by urban tree populations include maintenance of favourable climate, energy savings, air quality benefits, atmospheric carbon dioxide reduction, stormwater runoff reduction, property value benefits, aesthetics, and other benefits. The monetary value of urban forests is also high. Budapest has an estimated 9–10 million trees in urban forests and gardens. The mean value of a 20-year-old street tree individual in Budapest was estimated to be 2–3000 USD.
A wide range of arthropod pests attacks urban trees. Damage caused by these pests varies from minor, often imperceptible injuries to complete death of trees. Because pesticides can be harmful to human health and the environment, and because urban residents may be exposed to pesticides used to control pests, most European countries have strong regulations on pesticide use in urban green spaces. Banning or restrictions on the use of some compounds combined with high costs limit the widespread use of chemical control in public areas. Therefore, pest management of urban trees should move from reacting to pest problems to a preventive approach by creating green spaces that enhance natural control of pest populations and therefore suffer less damage from pests.
Forficula species (Dermaptera: Forficulidae) are generalist predators playing a key role in the control of pest insects in the canopy of trees but also causing damage in some fruit crops. European earwig, F. auricularia sensu lato (s.l.) has a cosmopolitan distribution and form very abundant populations in a wide range of habitats. F. auricularia s.l. has only recently been divided into three morphologically indistinguishable species (González-Miguéns et al. 2020) and therefore little is known about the differences in the ecology of the new sister taxa. In contrast, F. smyrnensis (distant species from the F. auricularia complex) is native in the eastern Mediterranean basin, and its range is rapidly expanding westward in Europe. However, the biology of F. smyrnensis is almost unknown. Both F. auricularia s.l. and F. smyrnensis are common in urban and seminatural habitats.
The objective of the studies is to determine the role of urbanization in the composition, distribution, fitness, behaviour, genetic isolation, and pest control ability of these key predators. The main task of the PhD student is to perform high quality research in the field of urban entomology, insect behavioural ecology and pest management and publish the results in highly ranked journals.
