Medical Entomology
Objectives
After this unit, students should be able to: 1. Define Medical Entomology in the context of International Health 2. Define arthropod vector, describe and distinguish types and mechanisms of transmission of pathogens 3. Describe the medical importance, geographic distribution, life cycles and bioecology of arthropod groups: Pentastomida; Scorpionida; Araneae; Acari; Triatominae; Cimicidae; Phtiraptera; Siphonaptera; Simuliidae; Ceratopogonidae; Phlebotominae; Culicidae; Tabanidae; Glossinidae; Muscomorpha 4. Identify specimens of the above arthropods, using dichotomous keys 5. Define the concept of vectorial efficiency, vector competence, vectorial capacity 6. Characterize the epidemiology of vector-borne diseases 7. Describe the techniques for entomological surveys 8. Discuss the methods for vector control 9. Analyze the introduction of exotic species in the context of climate change and vector-borne re/emergent diseases
