This document discusses the anatomy and structures of the insect head and appendages. It begins by describing how the insect body is segmented and then grouped into three main tagmata: the head, thorax, and abdomen. It then focuses on the structures and segmentation of the insect head, including the sclerites, sutures, mouthparts, and types of heads based on mouthpart positioning. The document also discusses the antennae and its various modifications, as well as the structures and modifications of the legs between different insect orders.
The document summarizes the structure and segmentation of the insect body. It is divided into three main parts:
1. The head, which is formed from the fusion of seven segments and contains the mouthparts, eyes, and antennae.
2. The thorax, which is composed of three segments - prothorax, mesothorax, and metathorax. Each segment contains a dorsal notum, lateral pleuron, and ventral sternum. The mesothorax and metathorax make up the pterothorax which bears the wings.
3. The abdomen, consisting of 9-11 segments. Each segment contains a dorsal tergum and ventral sternum
The document discusses the order Apterygota within the class Insecta. It notes that Apterygota has 4 orders: Thysanura, Collembola, Protura, and Diplura. For each order, it provides key characteristics such as body structure, presence of eyes and antennae, mouthpart type, wing presence, abdominal segmentation, and reproductive features.
The document summarizes body segmentation and external genitalia in insects. It describes how an insect's body is divided into three segments - the head, thorax, and abdomen. Each segment has distinct features - the head contains antennae, eyes, and mouthparts, the thorax contains three pairs of legs and sometimes wings, and the abdomen contains the digestive and reproductive organs. External genitalia like the ovipositor are also discussed, which can take different forms like needle-like, sword-like, or modified for stinging.
This document provides instructions for exercises examining the morphology of insects including cockroaches, mosquitoes, sandflies, biting midges, and blackflies. It describes the procedures for examining both external and internal anatomy of these insects as well as their immature stages. Key structures are defined for each insect group, such as the segmented body, antennae, wings, legs, mouthparts, circulatory and digestive systems. The exercises aim to teach insect morphology and aid in identification of specimens.

Wings occur on the mesothorax and metathorax. The thorax contains nota (dorsal plates), sterna (ventral plates), and pleura (lateral plates) that form a box-like structure and play an important role in locomotion. Legs occur on each thoracic segment and have six segments - coxa, trochanter, femur, tibia, tarsus, and pretarsus. Leg segments can be modified for different functions like
This document discusses the classification of insects. It divides the class Insecta into two subclasses: Apterygota and Pterygota. Apterygota includes primarily wingless insects with no metamorphosis. Pterygota is further divided into Exopterygota and Endopterygota. Exopterygota undergo incomplete metamorphosis and include orders like mayflies, dragonflies, and grasshoppers. Endopterygota undergo complete metamorphosis through distinct larval, pupal and adult stages, and include orders such as butterflies, flies, beetles and ants. Examples are provided for most orders.
The insect head contains openings for the mouthparts and prothorax. Mouthparts can be hypognathous, prognathous, or opisthognathous depending on the orientation of the head. The head also contains compound eyes, ocelli, and segmented antennae. There are six fused segments that make up the mouthparts: preantennal, antennal, labral, mandibular, maxillary, and labial. Mouthpart structure varies between insects and can be mandibulate, lapping/chewing, siphoning, sponging, or piercing-sucking depending on the insect's feeding habits. Antennae serve sensory functions and come in various shapes

Behavioral toxicity is the study of abnormal behavior caused by chemicals found in the environment or workplace. It examines the effects of toxicants like pharmaceuticals, heavy metals, solvents, pesticides, and air pollutants on behavior. Toxicants can influence behaviors like chasing, catching, handling, and swallowing prey. They may cause restlessness, rapid movement, breathing issues, and loss of balance in fish. Heavy metals in particular are linked to symptoms ranging from fatigue and depression to neurological deficits like tremors. Herbicides and endocrine disruptors can also negatively impact the nervous system and behaviors.
Physiological responses to toxicity summarizes the effects of environmental pollutants and toxicants on various physiological systems in aquatic organisms and other animals. Toxicants can disrupt sensory, hormonal, neurological, and metabolic systems, with implications for fish behavior. Commonly observed links between toxicant exposure and behavioral disruption include cholinesterase inhibition, altered neurotransmitter levels, and sensory deprivations. Toxicants can have systemic effects after absorption and distribution throughout the body or local effects at the contact site. Target organs most susceptible to toxic effects include the blood, liver, kidneys, skin, nervous system, and respiratory system. The physiological impacts range from minor irritation to organ damage and failure.
Ancylostoma duodenale, commonly known as hookworm, has a life cycle where adult worms live in the small intestine of humans. Female hookworms lay eggs that pass in stool and develop into infective larvae in soil. These larvae can penetrate the skin and travel to the lungs before being swallowed and maturing in the small intestine. Symptoms include abdominal pain, anemia, and blood in stool. Diagnosis involves microscopic examination of stool samples to find eggs. Treatment involves anthelmintic medications like albendazole. Prevention focuses on hygienic sanitation and avoiding barefoot contact with contaminated soil or grass.
1) Vector borne diseases are transmitted by arthropods like mosquitoes and flies or other living carriers like snails. Common diseases include malaria, dengue, typhoid, and sleeping sickness.
2) Lymphatic filariasis is caused by parasitic roundworms transmitted via mosquito bites. It causes swelling in the lymph nodes, limbs, and genitals.
3) Leishmaniasis is transmitted by sandfly bites and causes symptoms ranging from skin sores to damage of internal organs.
4) Scabies is caused by the scabies mite burrowing into the skin and is transmitted through direct skin-to-skin contact.
This document discusses several protozoan parasites that can cause human disease. It describes the life cycles, transmission, symptoms, diagnosis, and treatment of Giardia lamblia, Plasmodium species (which cause malaria), and Toxoplasma gondii. Key points include:
- Giardia lamblia causes giardiasis through ingestion of cysts in contaminated food or water which then transform into trophozoites in the intestines. Symptoms include diarrhea and abdominal pain.
- Plasmodium parasites spread through mosquito bites and cause malaria, infecting red blood cells. Malaria symptoms include fever, fatigue and anemia. It is a major global infectious disease killer
Economic zoology deals with applying zoological knowledge to benefit humanity, such as culturing animals for mass production and controlling or eradicating animals that harm people. Protozoa are microscopic single-celled organisms that can infect humans and cause diseases like malaria, giardia, and toxoplasmosis. Some protozoa classes include sporozoa, flagellates, amoeba, and ciliates. Trypanosoma are parasitic flagellates that cause sleeping sickness and Chagas disease in humans through transmission via insect vectors like tsetse flies and reduviid bugs.

Immersive Learning That Works: Research Grounding and Paths ForwardLeonel Morgado
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.

Authoring a personal GPT for your research and practice: How we created the Q...Leonel Morgado
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.

The binding of cosmological structures by massless topological defectsSérgio Sacani
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.
Describing and Interpreting an Immersive Learning Case with the Immersion Cub...Leonel Morgado
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.
hematic appreciation test is a psychological assessment tool used to measure an individual's appreciation and understanding of specific themes or topics. This test helps to evaluate an individual's ability to connect different ideas and concepts within a given theme, as well as their overall comprehension and interpretation skills. The results of the test can provide valuable insights into an individual's cognitive abilities, creativity, and critical thinking skills

2. Tagmosis
Insect body is differentiated into three distinct regions called head, thorax and abdomen
grouping of body segments into distinct regions is known as tagmosis
the body regions are called as tagmata.
HEAD
First anterior tagma formed by the fusion of six segments namely preantennary, antennary,
intercalary, mandibular, maxillary and labial segments.
Head is attached or articulated to the thorax through neck or Cervix.
Head capsule is sclerotized and the head capsule excluding appendages formed by the fusion of
several sclerites is known as Cranium
3. HEAD
The head of an insect is composed of a series of segments
specialized for food gathering and manipulation, sensory perception, and neural
integration.
The head bears the eyes (compound eyes and ocelli), antennae, and mouthparts.
Frons
Gena
Clypeus
Vertex
Occiput
4. Functions of Head
Food ingestion
Sensory perception
Coordination of bodily activities
Protection of the coordinating centers
TYPES OF INSECT HEADS
Based on the inclination of long axis of the head and orientation of mouth parts there are three types of insect
heads.
HYPOGNATHOUS (Hypo – below; gnathous – jaw)
This type is also called orthopteroid type. The long axis of the head is vertical. It is at right angles to the long
axis of the body. Mouth parts are ventrally placed and project downwards.
PROGNATHOUS (Pro- infront ; gnathous – jaw)
This type is also called coleopteroid type. The long axis of the head is horizontal. It is in line with the long axis
of the body. Mouth parts are directed foreward. Eg: groung beetles.
OPISTHOGNATHOUS (Opistho – behind ; gnathous – jaw)
This type is also called hemipteroid type or opisthorhychous. Head is deflexed. Mouth parts are directed
backwards and held in between the fore legs. Eg: Stink bug.

6. THORAX
Thorax tagma ….> three segmented, namely prothorax, mesothorax andmetathorax.
Meso and metathorax with wing are called as Pterothorax.
Thorax is made up of three scleritic plates namely, dorsal body plate (Tergum or
Nota, ventral body plate (Sterna) and lateral plate (Pleura).
Thoracic nota: Dorsal body plate of each thoracic segments are called as pronotum,
mesonotumand metanotum respectively.
Thoracic sterna: Vental body plate of each thoracic segments are called as
prosternum, mesosternum and metasternum..
Thoracic pleura: Lateral body wall of thoracic segment between notum and sternum.
Functions of thorax: Mainly concerned with locomotion.
7.
8. ABDOMEN
Third and posterior tagma.
This tagma is made up of 9-11 Uromeres (segments) and is highly flexible.
abdominal segments are telescopic in nature and are interconnected by a
membrane called conjunctiva.
Each abdominal segment is made up of only two sclerite
dorsal body plate (tergum) and ventral body plate (sternum).
Eight pairs of spiracles are present in the first eight abdominal segments, in
addition to a pair of tympanum in the first abdominal segment.
Eight and ninth abdominal segments contains the female genital structure and
ninth segment with male genital structure.
Abdominal appendages are genital organs and cerci.
Function: Concerned with reproduction and metabolism
11. Antennae
Antennae vary greatly among insects
follow a basic plan: segments 1 and 2 are termed the scape and
pedicel, respectively.
The remaining antennal segments (flagellomeres) are jointly
called the flagellum.
12. Antennae function
sensory perception
motion and orientation
odor
sound
humidity
a variety of chemical cues

14. 1. CLAVATE
Clavate antennae are gradually clubbed at the end. Examples: Carrion beetles (order
Coleoptera). Adult carrion beetles feed on decaying animal matter or maggots.

15. 2: GENICULATE
Geniculate antennae are hinged or bent like an elbow.
Examples: Bees and ants (order Hymenoptera).
16. 3: CAPITATE
Capitate antennae are abruptly clubbed at the end.
Examples: Butterflies (order Lepidoptera).
17. 4: FILIFORM
Filiform antennae have a thread-like shape.
Examples: Ground and long horned beetles (order Coleoptera),
cockroaches (order Blattaria).
18. 5: Aristate
Antennae are pouch-like with a lateral bristle.
Examples: house and shore flies (order diptera).
Used to detect air movement and odors.
19. 6: Lamellae
Lamellate or clubbed antennae end in nested plates.
Examples: Scarab beetles (orderColeoptera)
