Prerequisites:

Systemic diseases
Students are not compelled to take preliminary exams before this course. However, it is advised that students have taken the exam Grapevine pathology, as the present module represents the completion from a practical point of view.

Arthropod and nematode pests
No prerequisites are required to take the exam of the free course but it is strongly recommended for students to have already followed the lessons of the previous course “Viticultural Entomology”, as the new free course completes the previous one on a practical point of view.

Objectives

Systemic diseases
The main objective of this module is to increase the technical abilities of the students in monitoring and controlling the most important systemic grapevine diseases.
Students improve their practical knowledge regarding the most widespread grapevine systemic disease and the course provides them concepts about major pathogen agents, as phytovirus, phytoplasmas and their disease patterns. Further, field aspects will consist in: symptomathology, diagnosis, epidemiology, preliminary control and sanitation. In the laboratory students will exercise diagnostic techniques in order to improve crop sanitary status applying the sanitary selection method and to recover grapevines by meristem culture.

Arthropod and Nematode Pests
The main objective of the module "Arthropod and Nematode Pests” of the free course “Monitoring of pests and diseases of grapevine” is to increase the practical expertise of students on the main techniques of monitoring and control of main pests, mites and nematodes that are harmful to the vine in Sardinia. Students will be guided to gain practical experience in order to be able to monitor the main grapevine pests.
The course will be held in close collaboration with the course “Viticultural Entomology” of Prof. Lentini and completes the latter from a practical point of view, as the topics of pest monitoring and control will be thoroughly studied in the field.

Contents

-Background of the main biotic adversity of the vine in Sardinia to enable students who have not taken the exam of “Viticultural Entomology” to know the context in which the course will take place.
- Generalities on nematodes: Features of morphology, anatomy and biology. Nematodes of viticultural interest (cycle, damage, control). Main monitoring, extraction and control techniques.
- General information on mites: background of morphology, anatomy and biology. Mites of viticultural interest (cycle, damage, control).
- Special attention will be paid to direct and indirect monitoring techniques of the following pests: emipteran cicadellids (Jacobiasca libica, Empoasca vitis, Zygina rhamni) and pseudococcids (Planococcus ficus), lepidopteran tortricids (Lobesia botrana) e pyralids (Cryptoblabes gnidiella).
- Set-up of pest monitoring devices and placement of traps in field.
- Direct pest sampling techniques and periodic monitoring of traps and sampling carried out directly by students, acquiring thus expertise in the identification of pests.

Recommended Bibliography

The course does not include the use of a specific book, but Powerpoint presentations will be produced instead and provided to the students. The material provided will focus on images and practical advice on the means for monitoring and control of grapevine pests.
