Prerequisites
We recommend completion of the Bi6760 Basic entomology course, all students interested in insects are, however, welcome.
Course Enrolment Limitations
The course is also offered to the students of the fields other than those the course is directly associated with.
fields of study / plans the course is directly associated with
Course objectives
The course aims at extending the lectures on the basic general entomology and insect systematics (corresponding courses Bi6760 Basic entomology and Bi8780 System and phylogeny of insects) by a more detailed focus on selected general topics in morphology and ecology of insects which will be discussed (not only) from an evolutionary perspective. At the end of the course students should be able to explain and discuss possible reasons for the diversity and evolutionary success of insects and compose and combine the acquired knowledge within a wide context.
Syllabus
  • 1. Insect morphology and evolution 1. Current knowledge of the system and phylogeny of insects. Key evolutionary innovations for evolution of insect diversity. Internal fertilization, ways of sperm transfer, hypotheses explaining diversity of insect genitalia. Six legs, dicondylous mandibles, wings and mechanisms of wing folding. Ovipositor, viviparity in insects. Types of ovarioles, trophocytes.
  • 2. Insect morphology and evolution 2. Different opinions on the homology of some insect organs. Insect leg and mouthparts. Wing and hypotheses on its origin – evidence and critique of different theories.
  • 3. Insect onthogeny and evolution. Phases of onthogenetic development of insects. Structure of insect egg. Embryogenesis, determination of insect body plan. Organogenesis. Postembryonal development, types of metamorphosis – ametaboly, hemimetaboly, neometaboly, holometaboly and hypotheses on its evolution.
  • 4. Palaeoentomology 1. Fossil record of Hexapoda. Types of fossils. Diversity of extant and extinct insects. Oldest Hexapoda. Extinct orders of Pterygota, origins of extant orders.
  • 5. Palaeoentomology 2 – applications and problems. Importance of fossils for entomology: dating of evolutionary events, improvements and testing of phylogenetic and biogeographical hypotheses, palaeoenvironmental studies. Techniques of study of fossil insects, their identification and their inclusion into phylogenetic analysis. Subfossil insects.
  • 6. Insects in extreme environment. Tolerance to high temperatures and dessication. Overwintering, diapause, cold hardiness. Insects in anaerobic environment - endoparasites and aquatic insects. Saline environment, oceans, osmoregulation. Insects in toxic environment. Insects in caves and subterranean spaces.
  • 7. Insect behaviour 1. Different approaches to the study of insect behaviour. Physiological background of insect behaviour - central nervous system, hormones. Simple reflexes and motoric patterns, fixed action patterns, learning and memory, social learning, intelligence. Movement and orientation in space, migration, polymorphism and polyphenism.
  • 8. Insect behaviour 2. Forms of insect communication. Visual communication, bioluminescence. Mechanical communication, properties and ways of sound production, transfer and reception of sound and vibratory signals, bioacoustics. Chemical communication, types of semiochemicals, chemoreception, pheromones, cuticular hydrocarbons, properties and evolution of pheromone systems, allelochemicals. Strategies of insect defense, cryptic coloration, mimesis, mechanical defense, chemical defense, aposematism, mimicry, collective defense in social insects.
  • 9. Social insects. Definition and occurrence of eusociality in insects, life cycle of social insects. Problems of explanations of altruism, hypotheses on the origins of eusociality. Other types of sociality in insects, gregarious and subsocial behaviour, colonies, quasi-sociality. Polymorphism in eusocial insects. Diversity, biology and phylogeny of individual eusocial lines of insects.
  • 10. Insect and plants 1. Basic characteristics, diversity and evolution of phytophagous insects, different types of phytophagy. Theories explaining diversity of phytophagous insects, mechanisms of plant defense, adaptations of insects for life on plants. Impact of phytophagous insects on plants.
  • 11. Insect and plants 2. Pollinators and plants - problem of mutualism, strategies and adaptations, evolution of pollination and insects. Ants and plants. Fungivorous insects – review of fungivorous taxa, symbiotic fungi in ants, termites and scolytid beetles.
  • 12. Predation and parasitism in insects. Adaptations of predatory insects. Review of parasitoid taxa of insects, their biology and interactions with hosts. Insect parasites. Evolutionary success of insect parasitoids, parasites, herbivors and pollinators, problem of coevolution with hosts.
  • 13. Symbionts and pathogens of insects. Symbiotic microorganisms in insects, particularly termites, xylophagous, haematophaous and plant-sucking insects. Ultraselfish bacteria, cytoplasmatic incompatibility, determination of sex in insects, feminization, male-killing, parthenogenesis, and their practical use. Review of insect pathogens: viruses, bacteria, fungi, microsporidia.
