Educational objectives Knowledge
1. Basic knowledge of general entomology
2. General morphological features of insects
3. Internal anatomy features of insects
4. Features of the most important Hexapod orders.
Skills
1. Distinguish the main order of insects
2. Observation and insect dissection under a stereomicroscope

Behaviours
1. Conscious of the importance of insects and of their role in the relationships with the humans
2. Sensitive to the problems of conservation of insect biodiversity
Prerequisites Prerequisiti PREREQ Sì Al fine di meglio comprendere i diversi aspetti della morfologia e fisiologia degli insetti è consigliabile aver sostenuto con successo l’esame del modulo “Modelli animali” del corso di “Laboratorio di biotecnologie”. In order to better understand the different aspects of insect morphology and physiology, it is strongly advised to have passed “Modelli animali” in the course “Laboratorio di biotecnologie”
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 will be carried out in the laboratory and will be aimed at providing a practical knowledge of the structure of organisms studied during the frontal lessons. Samples will be dissected to evaluate the differences in the organization of the mouthparts, legs, antennae, wings and abdominal appendages. Observations will be also carried out by examining photographic material and specimens prepared and / or collected in the field and then observed using a stereomicroscope. This will enable the classification and determination of taxonomic groups of interest.
Other information Altre informazioni ALTRO Sì La frequenza delle lezioni è opzionale ma fortemente consigliata. Per migliorare la capacità nella classificazione dei principali ordini di insetti è fortemente consigliata la raccolta in campo di esemplari e la preparazione di una piccola scatola entomologica. Attending the lectures is optional but strongly advised. The field collection of insect specimens of the most important Orders are strongly advised to improve the ability in the insect classification.
Learning verification modality The exam is an oral test consisting of an interview lasting about 20 to 30 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 main objective of the course is to provide basic knowledge on the morphology, anatomy, physiology and bio-ethology of insects.
In particular the course includes the following topics:
Importance and diversity of insects. Insects general features: integumentary system; external morphology (head, antennae, mouthparts, thorax, legs, wings, abdomen); internal anatomy (Muscles and locomotion, nervous system, endocrine and exocrine system and the function of hormones, circulatory system, tracheal system and gas exchange, gut, digestion, and nutrition, excretory system, reproductive organs); feeding habitus; reproduction and development; outlines of systematics
