Biology through Bugs! Is designed to enable high school biology teachers to use insects throughout the course of instruction in biology. Insects are cheap, easily reared, alternatives to vertebrate models for classroom use. A general background in insect biology and ecology is included, as well as the preparation of an insect collection suitable for use as a reference collection.  The broad areas covered in the course include:

 

Evolution      Arthropods are among the oldest complex organisms, and insects and related arthropods were the first terrestrial animals.  Important points in their evolution and adaptive radiation into terrestrial habitats will be discussed relative to that of the vertebrates.  Basic concepts of evolutionary theory will be presented.

 

Life History  The growth and development of insects from eggs to reproductive adults will be examined.  An overview of internal structure and function will compare the insects approach to homeostasis to that of vertebrates.  Metamorphosis and molting will be emphasized.  Dispersal and migration, reproduction, dormancy, and feeding behavior will be included in a general study of insect life history. These approaches to successful adaptation to their environment will be compared to vertebrate approaches.

 

Behavior       Armed with a brain with less neural capacity than the average home computer,  insects have managed to invade and survive in habitats ranging from the interior of a single seed to pools of crude petroleum.  The advantages and disadvantages of instinctive and learned behavior will be explored. Communication (particularly visual and chemical), and social behavior will receive particular attention and will be contrasted to vertebrate communication and social structure.

 

Ecology        Insects play critical roles in virtually all terrestrial, and most aquatic, ecosystems.  They are also excellent experimental subjects for basic ecological studies,  and our attempts to manipulate economically important species depend on application of ecological principals.  We will focus on population and community ecology,  including general principals and specific examples using insects.

 

 

 

GRADING

 

The final course grade will be the percentage of total points that each student earns, based on the following point schedule:

EXAMS

 

Two 1‑hour exams are scheduled during regular class meetings.  Although exams are not intended to be cumulative, some overlap is inevitable. Exams will consist of short answer and short discussion questions.  Discussion questions are designed to allow you to integrate facts into a meaningful presentation of a topic.  Your discussion should be concise but thorough, and should consist of several well conceived paragraphs.  Illustrations are encouraged where appropriate, but they should not be substituted for text.

 

 

 

LAB QUIZZES & REPORTS

 

Laboratory exercises will supplement lecture material and are an integral part of the course.  Grading instruments will include lab quizzes and written reports.  Quizzes will test objective knowledge of the material covered in the lab,  while reports will test your ability to summarize materials,  methods and results of laboratory experiments and demonstrations. Labs will be geared toward the types of labs suitable for high school level biology instruction. Students enrolled in the graduate level course (NR847) will also be expected to prepare a laboratory on a topic of their own choosing related to insect biology, behavior or ecology.

 

OFFICE HOURS

 

I will maintain formal office hours (TBA),  but feel free to "drop in" for informal discus­sion or questions any time.
