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.
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)
Prerequisites for admission
It is advised to have knowledge of elements of biology and primary productions.
Assessment methods and Criteria
The exam consists of an oral test and takes place on a single date for both Learning Units.
There are no ongoing checks. During the year, various exam sessions are proposed during the periods set by the didactic regulation. The dates of the exsam sessions are regularly and officially published, in the times and in the manner prescribed by the regulations, on the SIFA web pages.
Students enrolled in an exam call and who no longer wish to support it are required to cancel the registration and eventually to notify the teacher promptly in the case of registration already closed.
For each individual module the interview on the topics in the program will be based on 2-3 questions, aimed at ascertaining the achievement of the teaching objectives. During the examination, descriptions or comments of images or diagrams related to the individual topics in the program may be requested. The exam will be passed reporting the sufficiency in both modules and the mark for each module contributes 50% to the formation of the final grade of the integrated exam.
DSA students - In order to take advantage of the facilities provided, must communicate their situation to the Unimi Disabled Office http://www.unimi.it/studenti/serviziodisabiliedsa.htm
. Furthermore, it is suggested to discuss with the lecturer during the frequency or during the preparation of the exam in order to have useful suggestions; in any case it is mandatory to communicate that the intention is to use the compensatory / dispensatory tools with adequate advance (at least 10 days) to the teacher to agree on the examination procedures, which remain the responsibility of the same.
