PhD position: Pest insect damages on oilseed rape

Oilseed rape is the main oilseed crop produced in temperate climates like Switzerland. However, numerous pest insects threaten its production that require high levels of crop protection and is difficult to achieve in low input or organic conditions. Sowing oilseed rape with legume companion plants has shown good results on weed suppression and nitrogen nutrition. However, their impact on pest insects is subject to large variations and the mechanisms involved still need to be clarified.
The role of oilseed rape genotype is also unclear.
In this research project, we aim to test a selection of genotypes grown with and without faba bean to identify the role of both genotype and companion plants on plant growth, as well as on the associated insect cohort and their severity, in order to propose a combination of measures to reduce crop protection and maintain yield in oilseed rape production. We also will characterize canopy characteristics like plant architecture, temp., quality of light, resources allocation, mineral composition in the plant and its surrounding environment that impact plant and insect development. The trials will be conducted both in the field and in controlled conditions.
