Professor Cohen is resuming teaching an insect rearing course in 2022. However, we are now trying a new approach with what we call “HYBRID COURSES” where students can take the for-credit courses as offerings from the NCSU Department of Entomology and Plant Pathology. The course is under the NCSU course offering called Entomology 591/791, designed for graduate students to learn about the science of insect rearing. These courses are full-credit (3 semester units) and involve lectures and laboratory practices, including a rearing project where each student goes through a rearing experience. This time, the students will be using the insect Galleria mellonella L. as their research subject, and they will rear their waxworms from 2nd instar larvae to 7th instar, using several different diets and following the design of experiments framework (response surface design and full-factorial design). The “for credit” rearing courses include a write-up of their research project and two mid-terms and one final exam where students are asked to write short and longer essays explaining various aspects of rearing systems that they are learning about in class.Students from 2019 Rearing Class This image shows the most recent class in insect rearing visiting Dr. Reiskind’s mosquito rearing laboratory. This was the last (“pre-COVID”) class that was taught in 2019. PLEASE CONTACT PROFESSOR COHEN AT accohen@ncsu.edu TO LEARN MORE ABOUT THE FOR-CREDIT COURSES.

Professor Allen Carson Cohen joined the Entomology Department (now Department of Entomology and Plant Pathology) at North Carolina State University as a research professor, he has taught several in person (on-site) classes in insect rearing.  He has also taught workshops in insect rearing and insect diets.  The on-site rearing courses have received high praise from nearly every student who has taken these offerings, and students especially appreciated the “know your insect” approach to rearing and the emphasis on treating rearing as a science with rigor and cross-disciplinary emphasis.

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.
