Learning objectives
The aim is to provide information on viticultural pests and pathogens, in detail:

PATHOLOGY

infromation on grapevine diseases, their spreading patterns and to evaluate their economic impact on production. To know how to prevent its early event and spread applying suitable integrated pest management programs.

ENTOMOLOGY

a) knowledge on biology, ethology of grapevine feeder insects (indigenous and exotic), as well as on damages caused to grapevine

b) build-up expertise on insect control strategies with emphasis on environmental friendly methods, IPM and biological control

c) Knowledge on the epidemiology of grapevine diseases transmitted by insect vectors and on prevention and control methods.
Expected learning outcomes
At the end of the course the student will be able:
- to recognize and manage grapevine diseases, their causal agents and their pattern of spread in vineyards.
- to apply traditional and modern diagnostic techniques for identification of the pathogens of grapevine. Modern pesticide usage and knowledge of the main related problems occurring in vineyard.
- to evaluate pathogen risk infection, its management also applying infection predicting models
- to identify the most important species of insects, indigenous and exotic, with a high risk of introduction, which cause direct damage and transmit agents of diseases of economic interest in viticulture
- to evaluate the influence of the environment on development of the insect populations in the vineyard, on the epidemiology of the plant pathogens they transmit
- to set up appropriate containment strategies, with particular emphasis on techniques with a low environmental impact
KNOWLEDGE AND UNDERSTANDING
At the end of the course the student will have theoretical and practical knowledge of:
- Impact of pest insects on grapevine production
- Role of vector insects in spreading grapevine pathogenic viruses and bacteria
- Grapevine insect pest control and prevention strategies, including insecticides and agronomical, mechanical, and biological tools, in order to obtain specific skills for designing and realizing IPM programs
APPLYING KNOWLEDGE AND UNDERSTANDING
At the end of the course the student will be able to:
-design prevention and control programs for several pests of grapevine
- design prevention and control programs for grapevine diseases transmitted by insect vectors
- design rational plans for the application of insecticides and alternative control methods in order to maximize efficacy and minimize side effects, thus preventing damages to beneficial insects and avoiding the selection of insect and fungi strains showing insecticide /fungicide resistance
INDEPENDENT JUDGEMENT
At the end of the course the students will be able to evaluate and choose the best control programs against selected pest insects of grapevine
COMMUNICATION SKILLS
The students will acquire a correct terminology on plant pathology, agricultural entomology and control methods. Moreover, by the analysis of papers and attending scientific seminars, they will develop the ability to analyse and understand scientific works
LEARNING SKILLS
At the end of the course the students will be able to evaluate and compare the different grapevine pests control options as well as to identify useful and reliable sources of scientific information
Single course

This course cannot be attended as a single course. Please check our list of single courses to find the ones available for enrolment.

Lesson period
First semester
Prerequisites for admission
No prerequisites
Assessment methods and Criteria
At the end of the lectures, the teacher will animate a discussion on the main arguments in order to highlight any learning problem. The aim of the discussion is to help learning process and estimate the learning level.
TThe final exam will be an oral interview. The exams will be held in person.
The interview aims to verify the capacity of reasoning and connecting the knowledge acquired
Entomology
Course syllabus
Introduction to insect pests of grapevine, feeding behaviour and resulting damage
Insect vectors of grapevine pathogens, transmission modalities
Mealybugs and scale insects of grapevine: biology, direct damages, transmission of Grapevine viruses and control.
Global status of vectors of Xylella fastidiosa to grapevine, risks of introduction and spread in Europe
Leafhopper and planthopper vectors of grapevine phytoplasmas and their control/management, also on the base of phenological predictive models. Flavescence dorée and Bois Noir epidemiology.
Non-vector grapevine leafhoppers (Empoasca vitis, Zygina rhamni). Phylloxera: biology and damages/control.
Grapevine berry moths: biology, monitoring, control methods.
Mites: their characteristics, biology, direct damages and transmission of Grapevine Pinot Gris Virus.
New, invasive species in the vineyard (Metcalfa pruinosa, Halyomorpha halys, Drosophila suzukii, Popillia japonica)
Concepts and principles of pest management, IPM, biological control.
Insecticides, their mode of action, resistance and resistance management.
Practices: identification of the main grapevine insects, field trip to a winery / grapevine nursery
Teaching methods
The course consists of about 30 hours of lectures and 10 hours devoted to laboratory activities and to an educational trip to a wine-producing farm and to Research bodies involved in grapevine protection.
Lectures and seminars will be provided in class. Alternative teaching methods (streaming) may be introduced exclusievly following new University recommendations
Teaching Resources
Scientific papers and materials (PowerPoint presentations) provided by the teachers will be loaded on the platform
Pathology
Course syllabus
The diseases of grapevine: a review of the main maladies of grapevine and in particular for those ones with epidemic pattern.
The sanitary selection of grapevine and its importance for the nursery industry.
The plant pathogen detection: the main innovations in serology and molecular biology for identification and characterization of grapevine pathogens.
Novel achievements for the containment and the management of the fungal diseases: the expert systems and their use for the disease management.
Novel achievements for the containment and the management of the diseases: new technologies and regulation protocols for the disease prevention and use of chemicals of lower impact for the environment.
Emergent pathogens and diseases of grapevine for Europe and other areas where grapevine is cultivated: quarantine regulation for grapevine material
Teaching methods
The course consists of lectures, seminars and laboratory activities.
Technical visits to to a wine-producing farm and research bodies involved in grapevine protection will be carried out.
The lessons will be held in person. Alternative teaching methods (streaming) may be introduced exclusievly following new University recommendations.
For both lecture modalities, the teacher makes use of PowerPoint presentations that are available to students together with articles for critical readings
