Flower strips are a known management strategy used in orchards and vegetable production which provide habitat for beneficial insects increasing biocontrol of pests and pollination of crop plants. Flowers strips between tree-rows however, are not widely implemented in fruit production because of logistical challenges such as additional machinery, and high efforts needed for establishing and maintenance of flowers strips. Table cherry orchards could benefit from flowering areas that promote the establishment of beneficial insects. In this project, we will exploit our experience in Agroecology, to promote biodiversity and natural pest control in modern orchards by testing two low input strategies. The overall goal of this research project is to test the use of either 1) perennial 'flower reservoirs installed in areas adjacent to the tree-rows where tractors etc. do not transit or 2) pre-planted 'flower boxes' distributed within the orchard in places where they do not disturb the management - can both promote the activities and establishment of beneficial insects. This MSc thesis project will focus on biocontrol agents and aphids, which are the focus pest. The goal is to assess whether the interventions promote the abundance and biodiversity of biocontrol agents and reduce aphid pressure.
You will work on farm, recording abundance and diversity of biocontrol agents and aphids in cherry orchards which have implemented flower reservoirs or boxes and in orchards without. You will learn how to use dedicated software for recording insect behavior. You need a drive license and should have good statistical knowledge.
