ENTO 320 is a 3-credit class available to science and non-science majors. Pre-requisites:  Junior or senior, or instructor's approval.

This is an introductory course on honey bee biology, evolution, management, and preservation.  It uses honey bees as a model organism to learn about the scientific process, as well as basic and applied concepts in biology, entomology, sociobiology, and the evolution of communication. Upon completion of ENTO 320, a student in this course will be able to:

  • Describe the basic principles of the scientific process
  • Identify honey bee anatomical and biological features and define their functions
  • Contrast how Apis mellifera has evolved into a unique honey bee species.  How does it differ from other bees?
  • Explain why honey bees sting, how they make wax comb, how they find a share food, how they reproduce and found nests, how they navigate, and how they pollinate
  • Recognize the generation and biological significance of Africanized and other tropical honey bees
  • Describe the history of beekeeping and discover the impact of apiculture on human society and the environment
  • Appraise how practices around the world are closely related to honey bee biology
  • List major common pests and pathogens of honey bees and current treatments
  • Interpret technical and scientific writing and write documents that are professional and scientific

Students conduct field research and complete class projects at the Archbold Tropical Research and Education Centre and adjacent Morne Trois Piton National Park. Individual and group research projects include insect ecology, veterinary studies, plant-animal interactions, aspects of Domincan environmental policy and related cultural questions. Students design projects, collect data, analyze results, and prepare a professional research article. Throughout the program students will be going on numerous hikes, some of which can be challenging, but the hikes allow the students to see and experience Dominica's diverse tropical flora and fauna. Students will also spend a good amount of time in and on the water conducting research and participating in program organized activities like snorkeling.  

All students are required to take a total of 6 credit hours to participate on this program.
