Forests are complex ecosystems, in which trees interact with an enormous diversity of microbial, fungal, arthropod and higher animal species. Many of these interactions are not beneficial for plants, considering for example pathogen infection and herbivore feeding. Especially trees with their large seize and long life span are under continuous attack, and commonly different attackers occur at the same time on the same tree.

Studies that were focusing on how plants defend themselves against herbivores and pathogens mostly considered single attack scenarios. My aim is therefore to elucidate how combined attacks influence the host tree as well as its attackers. As a model system I use black poplar trees (Populus nigra), the biotrophic poplar leaf rust fungus (Melampsora larici-populina) and herbivorous insects, mainly the gypsy moth (Lymantria dispar). I then investigate direct and indirect defense mechanisms of the tree, as well as their phytohormonal regulation and the consequence on insects feeding on fungal-infected hosts.
