Crediti massimi
Ore totali
AGR/11 AGR/12
Obiettivi formativi
The course is based on presentation and discussion of cases of study and scientific papers finalized to deepen the knowledge of biology, epidemiology and population dynamics of the most important pest and diseases of arable and fruit crops and forests. Regulations concerning the use of chemicals and biological control organisms will be used to propose sustainable pest and disease management strategies.
Risultati apprendimento attesi
The students will learn how to approach the problems related to the pest and diseases management of the most important arable and fruit crops and forest plants, both within the frame of integrated and organic agriculture. They will know the rules and regulatory restrictions related to the development and use of chemicals and biological control organisms for the management of known and alien pests and diseases.

{Modulo}: 'G58-189-B' - 'Unita' didattica 2: pest management': prof. Daniela Lupi
Tipo: 'Unità didattica'.

Case studies on the management of invasive pest insects will be detailed. The biology and dangerousness in relation to the environment of colonization will be detailed. Students will approach the different problems related to the management different invasive species both within the frame of integrated and organic control. Presentation and discussion of problems related to the consequences of uncorrect use of pesticides will be detailed (e.g. resistance to pesticides, trophobiosis, secondary effect on useful insects, colony collapse disorder).
Metodi didattici
Frontal lessons and specific seminars offered by known plant pathologists and entomologists expert of emerging or world wide known destructive plant diseases and pests.
Materiale di riferimento
Scientific papers and slides used by professors and, temporary, all recorded lessons, will be available for students in Ariel.

Modalità di verifica dell’apprendimento e criteri di valutazione
Students will be invited to propose a field crop or fruit crop or forest disease and pest of their interest. Once the two topics (1 plant disease and 1 pest) will be approved by teachers the students will prepare a seminar of about 30 minutes. The exame will consist of an oral presentation, slide assisted, of the seminar (about 30 minutes) and a final discussion with teachers (max 15 minutes). Professors will evaluate the completeness of the discussion, the property of language and the basic knowledge necessary to treat the case study analyzed.
The mark will be expressed in thirtieths.
