Learning objectives
Industrial plants can show different biotic agents, with significant consequences on customer satisfaction and on the hygienic and economic conditions. The student shall acquire knowledge about the main pests and the pest management control methods and about postharvest diseases and disorders caused by biotic agents, such as fungi and bacteria, and about their diagnosis, with the aim to manage product protection during storage.Industrial plants can show different biotic agents, with significant consequences on customer satisfaction and on the hygienic and economic conditions.

Pest and pathogen management
Course syllabus
Acquisition of knowledge referring the main problems of food pest control in processing and storing environments. Aspects of arthropod success. Potential arthropods vectors microorganisms. Insect morphology: tegument, head, chest, abdomen. Muscular, nervous, digestive, respiratory, circulatory, excretory, secretory, reproductive system. Development post-embryonic. Biology insect food and environment production and storage of food: Collembola, Thysanura, Psocoptera, Blattodea, Orthoptera, Lepidoptera (Pyralidae, Tinedae, Gelechidae), Diptera (Muscidae, Sarcophagidae, Calliphoridae, Piophilidae, Drosophylidae), Coleoptera (Curculionidae, Bostrychidae, Anobidae, Silvanidae, Bruchidae, Tenebrionidae), Imenoptera: (Formicidae, Vespidae, Apidae). Mites: features of morphology, anatomy and post-embryonic development. Development and control conditions. Prevention: environment, machinery, cleaning. Different food packaging resistance to insects attack: examining a hole in food packaging to determine infestation origin. Monitoring: direct visual examination, sieving, biological method. Filth-test method of analysis to detect arthropod fragments in a food: flours, pasta, honey, fruit juices, mushrooms, dried vegetables. Methods of analysis of infestations in environments: food traps, light traps, pheromone traps. How to use monitoring data. Physical control insect: controlled atmospheres, low and high temperatures, entoleter, inert dusts, vacuum. Insecticides: legislative references, formulated types, toxicity, knockdown effect, persistence, pyrethrum and pyrethroids, neonicotinoids, insect growth regulators and fumigants. Morphology and biology and ethology: Mus mus, Rattus rattus and R. norvegicus. Direct and indirect damages. Prevention and monitoring. Species detection, mechanical and chemical methods and results control. Outlines of pest management control of food and processing environments. Legislative references and considerations on Article 5 - 283/1962.

Course syllabus
Postharvest alterations and loss extent (physiological alterations, damages due to physical, chemical and biological conditions or parasites; losses from harvest to market). Outlines of plant pathology (the concept of disease in plants, classification of plant diseases, the cycle of disease, host-pathogen relationships). Pathogens in post harvest diseases (phytopathogenic fungi and bacteria, their pathogenesis) Main genera of fungi and bacteria that causes post harvest losses. Mycotoxins and mycotoxicoses Control of postharvest diseases (physical, chemical and biological methods; integrated control; residues and legal restrictions)
