Volume 2014/2015

Biology and ecology of major crop pests including, reasons for fluctuations and yield reducing attacks.
Different types of attacks, damages and crop loss functions, descriptions and assessments.
The influence on pests and natural enemies of weather, fertilization, irrigation etc.
Monitoring and forecasting systems, development and function in an IPM-frame.
Control methods and strategies, legal and advisory implications, IPM.
Attack prevention and manipulation of pest insects and their natural enemies through crop choice, crop structure, crop rotation and structure of farming system (organic, integrated and conventional).

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.
