The course aims to provide: i) basic knowledge and concepts of Plant Pathology and its fields of application (agricultural, forestry, ornamental, plantations, urban); ii) basic knowledge of mycology regarding biology and taxonomy of fungi; an overview of the main fungal diseases of trees and their impact in a national and European context a) Knowledge and understanding. Students will receive all the information necessary to form a complex cognitive framework but with a common denominator that will allow them to associate and integrate the individual topics covered. Through a non-notional path but based on analysis, discussion in class and the stimulation of the critical spirit, the student will understand and elaborate on the individual themes of forest pathology by placing them in the current national and European context. b) Applied knowledge and understanding; The set of information provided to the student through an interactive approach, and with practical application examples, will allow them to perceive its applicability in professional activities both nationally and internationally. Students will also have the opportunity to conduct practical activities which concern, in particular, the diagnostic procedure and protocols, their integration and use in practical field and laboratory activities. c) Making judgments; the interactive teaching method based on the framing of general themes and their development through practical examples and class discussions will stimulate the students' ability to combine personal and autonomous judgment. d) Communication skills; the body of information provided during the course will provide students with the tools to be able to effectively, and with knowledge of the facts, communicate the issues relating to the complex system of the impact of woody plant diseases in forestry, agroforestry, nursery and income plantation systems, using an appropriate glossary and the right dissemination approach. e) Ability to learn (learning skills); the adoption of a teaching method based on general concepts then developed with practical and applied examples, promotes student learning and, in particular, the assimilation of concepts

(objectives)
The aim of the course is to provide students with the basis for understanding the great biodiversity and importance of insects, particularly in forest environment. Morphology, anatomy and physiology of insects as well as methods for the evaluation and control of harmful insect populations, according to current legislation, will be addressed. In addition, methods are provided for the identification of the main groups and the knowledge of insects that infested the main plant species typical of the forest environment is deepened. The course pursues the following educational objectives: KNOWLEDGE AND UNDERSTANDING Development of knowledge of the basic principles of general and applied entomology; identification of the most important insects (order level) and comprehension of the role these organisms play in ecosystems. Learning the main monitoring strategies of insects and how to apply them correctly. Knowledge of pest control strategies. Knowledge of the main insects in forest environment. APPLYING KNOWLEDGE AND UNDERSTANDING Understanding of experimental approaches to entomology in forest environments discussed in class and their applications to specific cases. MAKING JUDGMENTS Interpretation of entomological issues, in analogy with what was discussed in class. Application of the knowledge acquired in the course to manage the various phytosanitary issues and to preserve taxa of interest. COMMUNICATION SKILLS Use of the correct technical-scientific terminology in the description of the course topics. Synthesis skills and communicative effectiveness in the description of the course topics. LEARNING SKILLS Knowledge of the topics of the course and critical ability to understand the crucial aspects of a phytosanitary problem, how to deal with it, and how to carry out the necessary insights.
