751-5110-00LInsects in AgroecosystemsW+2 credits2VS. Halloran, K. Mauck
AbstractThis class will focus on insect-plant interactions in Central European agroecosystems, and on regulators of insect pest populations. Lectures will cover important crop systems in central European agriculture. Within each system, major pests and their interactions will be described in an ecological context, focusing on key concepts in pest prediction and management.
ObjectiveAt the end of this course, students will have gained in-depth knowledge of the ecology of major pest species and their impacts within specific crop systems in Central Europe. Our approach will allow students to transfer this knowledge to related questions in other systems. Additionally, students will learn about current research goals in agroecology and how these goals are being addressed by scientists engaged in agricultural research.
ContentInsect-plant interactions in middle European agroecosystems are the focus of this course. Always starting from an important perennial or annual crop, specific insect species of economic significance are presented along with the life cycles, population dynamics, and the insect-plant interactions relevant to economic impacts on the crop. Natural factors which limit such damage are introduced, e.g. parasitoids and predators. Each section of the course is complemented by a basic ecological, biological or engineering theme or approach such as host shift, physiological time, or sampling techniques. Recent advances in research will also be addressed throughout the course and reinforced with periodic readings of recent primary literature.

751-4904-00LMicrobial Pest ControlW+2 credits2GJ. Enkerli, G. Grabenweger, S. Kuske Pradal
AbstractThis lecture provides conceptual as well as biological and ecological background on microbial pest management. Methods and techniques applied to develop and monitor microbial control agents are elucidated.
ObjectiveTo know the most important groups of insect pathogens and their characteristics. To become familiar with the basic steps necessary for the development of microbial control agents. To understand the techniques and methods used to monitor field applications and the procedures involved in registration of products for microbial pest management.
ContentDefinitions and general terms used in microbial control are presented. Biological and ecological aspects of all arthropod-pathogenic groups (virus, bacteria, fungi, protozoa and nematodes) as well as their advantages and disadvantages in relation to biocontrol are discussed. Particular emphasis is put on hypocrealean and entomophthoralean fungi. Examples are used to demonstrate how projects in microbial control can be set up, how pathogens can be applied and how efficacy, non-target effects, persistence and dissemination are monitored. Furthermore, the necessary steps for product development, commercial aspects and registration requirements are discussed.

751-4902-00LModern Pesticides - Mode of Action, Residues and Environmental FateW+2 credits2VM. Müller, I. J. Bürge, T. Poiger
AbstractThe biochemical principles of the mode of action of plant protection products (PPP) are presented. Important topics are mechanisms for selectivity, development of resistance, residue formation in crops and food safety as well as behavior in the environment.
ObjectiveThe structures and modes of action of modern pesticides (synthetical compounds, natural compounds) are presented. The structure-activity relationships lead to considerations of actual use conditions in crops such as fungicides in viticulture, residues in edible parts of treated plants, possible side effects and environmental fate.
ContentAfter a short introduction on pesticide registration (administrative process as in Switzerland and EC, food safety), the biochemical background of the mode of action of important groups of PPP active ingredients is presented. Furthermore, selectivity of pesticides, leaching of herbicides to groundwater, accumulation of pesticides in soil, development of resistance of fungicides, formation of residues in edible parts of the crops, and side-effects on non-target organisms shall be covered.
Lecture notesAn e-script (pdf-files, in German) is is provided as download at the beginning of spring term.
