Learning outcomes

The Course is divided in 2 teaching Units (Plant pathology and Entomology). The aim of the course is to provide knowledge on the biology of the main pathogens and arthropods harmful to grapevine, their interactions with the plant and their relative control methods. Particular attention will be given to pathogenicity mechanisms, plant resistance responses, biological and integrated control measures and to biotechnological applications for disease and pest management. At the end of the course, the student will be able to recognize the main grapevine biotic diseases and to apply a rational and environmentally friendly approach against grapevine disease and harmful arthropods.

Program

------------------------
MM: ENTOMOLOGIA
------------------------
Arthropods characteristics and classification . Morphology, physiology and ethology of insects and mites harmful to grapevine. Nervous, digestive, respiratory, circulatory, reproductive, excretory and endocrine systems. Reproduction and cycle development. Population dynamic: biotic potential and environmental resistance. relationship between insects and other organisms: viruses and phytoplasmas transmission. Insect: Classification, biology, damage and control of the main grapevine pests (e.g. moths, phylloxera, leafhoppers, scales and thrips). Grape’s minor pests. Mites and Nematodes: Grape mites and nematodes, biology, ecology and damages. Pest management: Damage threshold. Chemical control and insects management. Insecticides: general information, mode of action, selectivity and phytotoxicity. Pest resistance management and man-made pests. Biological and integrated pest control. Cultural and mechanical control. Biotechnologies in pest management: pheromones definition and application, mass trapping, RNAi, sterile male technique. The knowledge will be developed with lectures, laboratory activities and personal study on the texts and on the material presented in class that will be available in the Library and/or uploaded to e-learning platform. Moreover, throughout the academic year, the individual reception service will be available (by specific appointment). Attending students will receive in the first lesson the complete timetables of teaching activities with the dates and topics discussed in the lessons

Examination Methods

------------------------
MM: ENTOMOLOGIA
------------------------
The exam will be made in oral form for both attending students and non-attending students. Under health emergency, this oral mode can be changed in remote telematics one. The attendance at the practice exercises is mandatory in order to be eligible to do the exam. The exam will assess the degree of knowledge on the topics presented during the lectures. The knowledge and the ability to connect knowledge in a systemic and critical way will also be evaluated. The final evaluation is expressed in thirtieths. To determine the overall grade of the exam, the weighted average of the votes obtained in the two modules will be calculated.
