NPLK18001U Applied Insect Ecology and Biological Control
MSc Agricultural Development
Management of pests requires an ecologically based knowledge and understanding of their biology, lifecycle and their interaction with host plants and their natural enemies. Also, climate and cropping practices will affect these dynamics and the resulting management strategy. The course will focus on management of insects and mites on plants with a special focus on how to apply insect ecological methods and biological control.
- Applied insect-plant ecology and the influence of abiotic factors and agricultural practices on crop pest and their natural enemies
- Monitoring and forecasting methodologies and management strategies
- Natural enemy groups: predators, parasitoids, microorganisms, nematodes and their ecology: life cycles, and mechanisms of action in relation to their prey/host
- Methods for isolation and selection of biological control organisms, available commercial biocontrol organisms
- Prevention of attacks and manipulation of pest insects and their natural enemies through rotation and choice of crop, functional biodiversity, cropping system
- Cases of practical application within agriculture, horticulture, forestry, husbandry, urban environment and other managed landscapes
- Ethical aspects, public acceptance, legislation and risk
The students will perform and report a limited set of experiments related to biological control. The options may vary from year to year. Examples are:
- Insect prey and insect predator interactions (behaviour etc)
- The effect of temperature/diet/host plant on insect herbivore or predator
- Bio-assays using microorganisms for biological control
- Behaviour of insect pests to insect pathogens
Discussion of experiments in relation to relevant literature will be included in the students' short experimental reports.
Students will acquire a knowledge of crop pest insects, their
natural enemies, and biological interactions (including with the
crop itself) supporting environmentally friendly pest control.
After the course the student should be able to:
- Describe the principles and methods of monitoring insect pests of crops
- Describe the main methods to prevent and control insect attacks
- Describe and understand the strategies used in insect pest
management and biological control
- Know and characterize the main types of organisms currently used for or of future potential for biological control
- Describe methods used for diagnostics, isolation, characterization, bio-assays and field experiments of relevance for functional biodiversity and biological control
- Analyse and process monitoring results and work out and communicate a decision background for growers.
- Ability to select an organism for biological control in a specified system
-Ability to select relevant methods to study the interactions between natural enemies, target prey/host and environment
-Ability to analyse and decide about potential risks using biological control or other management method both in a specified system and in a more general context
- Ability to use scientific literature to discuss own data
- Explain the major concepts of insect pest management.
- Explain and discuss crop and production system effects on pest insects, natural enemies and other insects.
- Discuss ethical aspects of insect management
-Ability to transfer the knowledge into other decision processes
about multitrophic interactions of ecological relevance
- Ability to perform and analyse experimental work including two or three organisms
-Discuss innovative solutions to integrated pest management
- Ability to transfer the knowledge into other decision processes involving cross disciplinary elements, for example: biology, crop systems’ management, and ethics
