Anisandrus dispar (Coleoptera: Curculionidae) is a polyphagous Ambrosia beetle, with the capability of attacking both coniferous and broad leaf trees, thus becoming an economically important pests in the horticultural sector. These beetles are rising concern in the apple production as well. South Tyrol, one of the main apple producer region of Italy, the pest attack leads to the death of young apple trees and a decrease of apple production in older trees. This insect is difficult to control because it develops inside the tree trunk. As a result of cryptic behavior, effective control of this pest needs other strategies other than the traditional pesticide applications. Understanding the chemical ecology of this species may lead to a promising control method also in view sustainable agriculture. Previous study on Anisandrus dispar performed by our research group, showed that ethanol-modified funnel traps are able to attract many flying insects during their spring fly. The present study will explore the role of identified bioactive volatile compounds of apple and hazelnut wood, as host plat volatiles seem to play also important roles. During the present study I will perform electroantennography assays as well as fields test to test the attractiveness of bioactive volatile compounds of apple and hazelnut wood. . This thesis project is done in collaboration with Dott. Manfred Wolf, Unit of Entomology of the Laimburg Research Centre.
