Description: As a group insects are among the most successful and varied groups of organisms on Earth today. In many terrestrial ecosystems insects are the dominant animals in terms of numbers of species and biomass.  In addition insects have important relationships with other species that are critical for human welfare. Insects are both important agricultural pests and through pollination important agricultural allies. Fungal insect relationships are of critical importance in nutrient cycling in tropical and semitropical. Insects exhibit a wide range of interesting habits and behaviors and the study of insects has provided important insights into fields from genetics to social behavior and communication. The purpose of this course is to introduce students to the major groups of insects, their evolution, natural history and complex relationships between insects and people.

Content Outline and Competencies:

I. What is an insect anyway?

A. Explain the basic taxonomic categories used in biology today.

B. Describe the main characteristics of the phylum Arthropoda.

C. Discuss the importance of segmentation in the evolution of arthropods.

D. Identify representatives of the commonly seen classes of Arthropods.

E. List the features of the class insecta (insects) that distinguish them from the other arthropods.

C. Define and give examples of different types of chemical signals used by insects.

V. Mating and Social Behavior

A. Describe several different types of mating behavior found in insects.

B. Define social behavior and give examples of social interactions within groups of insects.

C. Describe the key features of eusocial behavior and compare eusocial behavior in ants, termites, bees and wasps.

A. Read and discuss examples of insects as portrayed in semi popular science writing such as by Eisner, Berenbaum and Faubre.

B. Discuss the portrayal of insects in science fiction, both in film and science fiction literature.

C. Give examples of insect biology’s contribution to understanding human biology

X. Insect identification.

A. Identify common representatives of the major orders of insects by sight

B. Practice using keys to identify insects and know what characters are important in insect identification. (we’ll keep this relatively non technical)

C. Demonstrate use of online resources for insect identification.

D. Describe common preservation methods for unknown insects for identification. (Sticking bugs to scotch tape is not it)

E. Take pictures of insects even if all you have is a cell phone.

Method of Evaluation and Competencies:

The grade for the course will be determined by the student’s performance on lecture exams, projects, and homework assignments.  A total of 400 points is possible for the course.  Grades are determined as follows:

300 points        Exams:  Three lecture exams at 100 points each
100 points        Insect Presentation
50 points          Daily discussion of insect news
50 points          Homework:

Grade Criteria Minimum Points Required

A           450-500
B           400-499
C           350-399
D           300-349
F           Less than 300

Caveats:  As weather and time permits we may make some on campus visits to see various insects; old clothes on those days and comfortable walking shoes are required for such trips.

Student Responsibilities: 

Computer use will be required: Students will need basic word processing and Internet searching skills for the completion of projects.  Regular attendance to ensure completion of the projects is expected. Students without computers can use the Science Division’s CASE classroom computers. An ID is required. Students should also be aware that there is a 200 page limit per semester.

All JCCC students are expected to follow the Student Code of Conduct.

Anyone caught cheating (including plagiarizing) will be subject to any or all of the following:  a zero for the work involved; an immediate “F” in the course; referral to college authorities for further discipline. 

Disabilities:

If you are a student with a disability, and if you will be requesting accommodations, it is your responsibility to contact Access Services. Access Services will recommend any appropriate accommodations to your professor and his/her director. The professor and director will identify for you which accommodations will be arranged.

JCCC provides a range of services to allow persons with disabilities to participate in educational programs and activities. If you desire support services, contact the office of Access Services for Students With Disabilities (913) 469-8500, ext. 3521 or TDD (913) 469-3885. The Access Services office is located in the Success Center on the second floor of the Student Center.
