Online Education: Introduction to Insect Rearing (March-May of 2022)

Please note the new format for our online courses. We no longer offer the self-timed rearing courses, and instead we offer all live (synchronous) courses. In the new format students attend class meetings via Zoom, and we use the Moodle system for presentation of class notes and course enrichment documents. These courses include about 60 hours of instruction by lecture, videos, and discussion, AND we provide extra instruction and interaction with Professor Cohen through email and through video communication where the students can exchange information and questions with the instructor. This format allows provision of course information of the general concepts of insect rearing, along with opportunity to develop an enhanced understanding of the students’ specific rearing issues.

These classes are scheduled to be taught live (via Zoom and Moodle) from 2:00-4:20 pm Eastern Time. However, we can arrange to have different times to accommodate people from time zones that are very different from the US times. For example, last year, I taught the classes from 7:00 to 9:20 pm (Eastern Time) to accommodate people in the Asian-Pacific region. We can arrange times for Asian-Pacific, African and European participants, provided that we can get five or more participants for each time frame. To meet the needs of our world audience, we can begin lectures at times that correspond with convenient local times.

Registration Fees: $250 for each course ($750 for all three courses).

Please note that these 3 courses can be taken in any sequence (i.e., Course 1 is not a pre-requisite for Course 2, etc.) However, there are unique materials in each course, so for a comprehensive rearing background, it is recommended that students take all three courses. The courses consist of eight 2 hour and 10-minute lectures, so the 3 courses (24 lectures) provide 52 hours of concentrated learning opportunity. Also, Professor Cohen encourages students to remain online after class to ask questions or discuss issues of particular interest to them. This feature gives students a further opportunity to get advice and feedback from their instructor. The extensive interactions in these courses are further enhanced by the opportunity to communicate special questions or issues via email. Professor Cohen believes deeply in the Socratic method of inquiry, and he fosters learning by being open to students’ interacting with the materials and he encourages students to further integrate what they have been learning in class with their experiences in their own rearing backgrounds.

Please note that the extensive, detailed summary of the 3 courses follows here:

These topics are taught in an inquiry-based, scientific, rationale-driven approach to rearing. In every module, this question is always of central importance: HOW DOES THE TOPIC RELATE SPECIFICALLY TO INSECT REARING?

For example, when we talk about movement and internal communication, we use examples of how (for example) mishandling insects such as tephritid flies leads to improperly-formed muscles, thus impacting flight. Or in discussing the nature of gas exchange (CO2 release and O2 utilisation), we discuss methods of measuring the levels of oxygen and carbon dioxide in rearing containers AND how the low O2 or high CO2 concentrations can lead to mitochondrial and breathing tube (tracheoles) deformities.

In these courses, we cover a lot of insect biology (physiology, nutrition, biochemistry, ecology, behavior, and genetics) but ALWAYS in the context of what these concepts mean to insect rearing.
