| Contents | The course aims to provide basic and applied knowledge on insects and other organisms harmful to hop crop and to cereals used for brewing. Insights will be provided on quantitative and qualitative damage caused by the various insect and mite pests. Knowledge about the different monitoring techniques and defence strategies will be also provided. The course aims to give the student a complete overview of the activities and issues relating to the reduction of losses during growing and storage. Program summary: Main pests harmful to hop crop and to cereals used for brewing: identification, biology, ecology, damage and management. Monitoring and economic thresholds. Biological, biotechnical, physical-mechanical and chemical methods. |

| Educational objectives | Knowledge Basic knowledge of entomology. Morphological and bio-ethological characteristics of the main pests of hop crop and of cereals used for brewing. Morphological and bio-ethological characteristics of the main pests of stored crops. Features of cereals and hop agroecosystems Damages caused by arthropods to cereals and hop Monitoring and collecting techniques of phytophagous arthropods Control methods of phytophagous arthropods Skills To recognize the most important arthropods harmful to cereals and hop Providing a program of monitoring and sampling To make a choice between different control methods to be applied to cereals and hop crop Behaviours To be sensitive to the risks associated with contamination of food To be sensitive to the importance of IPM of stored products. |
| Prerequisites | Knowledge on agricultural entomology (suggested) |
| Teaching methods | The lectures will cover the different topics listed in detail in the program. They will take part in the classroom with the support of slides projected during lessons, teaching material distributed by the teacher and / or published on the Unistudium platform, Videos, Suggested textbooks. Practical laboratory lessons and technical visits to specialized companies. |
| Other information | Attending the lectures is optional but strongly advised. |
| Learning verification modality | The exam is an oral test consisting of an interview lasting about 20 minutes to ascertain the student's level of knowledge and understanding capability acquired on the different contents indicated in the program. During the oral examination the student's communication skills will be also evaluated. The first part of the test will consist in verifying the capacity acquired in the classification of the main insect orders. |
| Extended program | The lectures will cover the following topics: Introduction to the most important arthropods harmful to cereals and hop and stored products. The "eco-systems" for stored products. Ochsenheimeria bisontella, Agromyza ambigua, A. mobilis, Oscinella frit, Oulema melanopus, Aelia rostrata, Eurygaster maura, Schizaphis graminum, Sitobion avenae, Rhopalosiphum padi, Metopolophium dirhodum, Zabrus tenebrioides, Haplodiplosis marginata, Dolerus gonager, Ostrinia nubilalis, Pseudaletia (=Mythimna) unipuncta], Agrotis segetum, Agrotis ipsilon, Diabrotica virgifera virgifera, Agriotes litigiosus, A. sordidus, A. ustulatus, A. brevis, A. lineatus ecc., [Helicoverpa (= Heliothis) armigera], Sesamia cretica, Sesamia nonagrioides, Sipha glyceriae, Trigonotylus caelestialium, Diptera: Chironomidae, Hydrellia griseola, Lissorhoptrus oryzophilus, Donacia dentata. Phorodon humuli), Tetranychus urticae, Agrotis segetum, Calliteara pudibunda, Cicadellidae, Popillia japonica, Cnephasia alticolana, Hydracea micacea, Hypena rostralis , Miridae, Nymphalis album, Nymphalis io, Orgyia antiqua, Ostrinia nubilalis, Thripidae. Sitophilus granarius e S. oryzae, Rhyzopertha dominica, Tenebroides mauritanicus, Trogoderma granarium, Sitotroga cerealella, Nemapogon = Tinea granella, Plodia interpunctella. For the most important species, the following aspects will be considered: general information; elements of taxonomy, morphology, anatomy, biology, ethology and ecology. The economic damage. Qualitative and quantitative losses. Monitoring techniques and economic thresholds. Means and methods of prevention. Control with biological methods, biotechnical, physical, mechanical and natural and synthetic chemicals. Integrated control strategies against major pests. |

| Type of study-unit | Obbligatorio (Required) |
| Language of instruction | Italian |
| Contents | During the course, the most important concepts of general plant pathology will be recalled and the most important diseases of crops used for beer production (barley, hops, wheat, maize) and the aspects related to cereal storage will be discussed. External visits at companies operating in the cereal and brewing sectors will be organised. |
| Reference texts | Material provided by the teacher. |
| Educational objectives | The main objective of the course is to give students basic knowledge to manage the problems related to beer crops diseases. The main acquired knowledge will be: 1. Basic knowledge of general plant pathology 2. Main diseases of beer crops and their control 3. Correct strategies for the storage of cereals 4. Problems related to mycotoxin contaminations The main abilities: 1. Identify the main beer crops diseases and their causal agents 2. Set up a correct diagnosis and adopt correct prevention and control strategies 3. Plan adequate monitoring and sampling programs 4. Identify the main risks related to the presence of mycotoxins Students will be: 1. Informed about the importance of beer crops diseases and of their storage on yield and quality 2. Informed about the risks related to mycotoxin contaminations. |
| Prerequisites | Knowledge of general Plant pathology. |
| Teaching methods | Theoretical classroom frontal lessons on the topics of the course, with the aid of PowerPoint presentations: 19 hours Practical laboratory lessons and technical visits to specialised industries: 8 hours. |
| Other information | Attendance is strongly recommended. |
| Learning verification modality | Oral examination. Information about support services to students with disabilities: http://www.unipg.it/disabilita-e-dsa |
| Extended program | The course will focus on the problems related to the yield losses caused by beer crops diseases and those related to their safety, quality and health. During the course, the most important concepts of general plant pathology will be recalled and the most important beer crops diseases will be discussed as well as the main problems related to their mycotoxin contamination. Practical lessons will be given on the isolation of pathogens from infected plant materials and microscopy will be used for their identification. Technical visits will be carried out in selected farms, industries and/or storage centers dealing with cereals and beer. |
