NPLK14025U Insects in Agricultural and Horticultural Crops

Volume 2017/2018

MSc Programme in Agriculture


Many insects interact with plants, which they use particularly for feed, shelter and fuel. If densities of herbivorous insects are high enough they can become crop pest which require attention and maybe action. To do this as economical and sustainable as possible requires an ecologically based knowledge and understnding of:

  • Insect-plant-ecology and more specifically the influence of soil, weather, fertilization, irrigation etc. on crop pest and their natural enemies.
  • Monitoring and forecasting methodologies (development and function of systems) as well as control methods and overall management strategies (incl. legal and advisory implications).
  • Prevention of attacks and manipulation of pest insects and their natural enemies through rotation and choice of crop, and farming system (organic, integrated, conventional).
  • Influence of plant protection on wild flora and fauna of arable fields.
Learning Outcome

The main objective is to establish a general knowledge to crop pest insects and their interactions with crop plants and natural enemies, which can support sound pest management.
After the course the student should be able to:
- List and describe a selection of important insect pests and their plant/crop effects.
- Describe the principles and methods of monitoring insect pests of crops.
- Describe the main methods to prevent and control insect attacks.
- Identify selected pest insects and beneficials based on morphological characters.
- Analyse and process monitoring results and work out and communicate a decision backgroound for growers.
- Communicate pest insect problems to fellow students.
- Explain the major concepts of insect pest management.
- Explain and discuss crop and production system effects on pest insects and other insects.
- Explain and discuss crop-pest interactions and management possibilities.
- Discuss ethical aspects of insect management e.g. related to use of chemicals and genetically modified plants as well as the environment.

All aids allowed

The University will make computers and power available to students taking written exams with invigilation in the University’s building at Peter Bangs Vej 36 (ITX). These students are therefore not permitted to bring their own computers, tablets or mobile phones. If textbooks and/or notes are permitted at a given exam, these must be in paper format or on a USB flash drive.
