Flowering plants and insects represent the two largest taxa of interacting terrestrial organisms, both in terms of abundance of species as well as in amount of biomass. The study of insect-plant interactions covers problems at different levels of biological analysis. This course focuses on the mechanistic analysis of nutritional and behavioural mechanisms of insects, and on the adaptation of plants to insects: defence against harmful insects, attraction of natural enemies of herbivorous insects and of of pollinators for plant sexual reproduction, through the production of attractive / stimulatory or repellent and/or toxic plant metabolites. Ecological and evolutionary aspects are addressed, using insights derived from studies at the organismal level as the basis of ecological interactions and models. Attention is paid to applications in crop protection. 

Learning outcomes:

After successful completion of this course students are expected to be able to : 
demonstrate knowledge and understanding of principles underlying molecular, physiological and biochemical interactions between plants and insects; 
demonstrate knowledge and understanding of implications of these interactions at the level of the organism on processes at other trophic levels and at the population level;
- define and explain concepts, provide arguments and give examples in writing in reply to exam questions;
- translate a biological question into a feasible experimental approach;
- demonstrate experimental skills in a range of methods and techniques commonly used in the subject area; 
- design, organise and carry out experiments;
- master the statistical analysis of quantitative data collected during experiments; 
- interpret results obtained in the context of existing literature, after a critical evaluation. 
Learning outcomes will be evaluated on the basis of a written report of max. 2000 words in the format of a scientific article. Students are expected to be able to present the research carried out orally to fellow students at the end of the course, making use of supportive electronic media.


- working sessions in which principles of insect-plant interactions will be presented and discussed based on recent literature;
- mini-research project: a number of experimental projects is offered making use of available plant and insect species and techniques. A range of measuring techniques and (semi-)automated set-ups for quantifying sensory and behavioural responses in insects and analytical equipment to quantify (volatile) metabolite formation in plants in response to insect herbivory are available. The results will be reported using the format of a short scientific publication of maximally 2000 words;
- oral presentation.


- written examination on contents of the course book and lectures (essay questions) 50%;
- evaluation of report on mini-research project (40%);
- presentation of project results to peers (10%).


Recent literature, both review papers and primary research papers, will be advised on during the course.
