Full course description
Electropenetrography (EPG) Online Workshop
The purpose of the course is to provide detailed instructional materials to learn how to perform electropenetrography (EPG) research. The course is designed for graduate students and professional researchers in Entomology, Veterinary and Medical Sciences, especially for those studying feeding of piercing-sucking arthropods such as hemipterans (aphids, leaf- and planthoppers, psyllids, whiteflies, mealybugs and others), biting flies (mosquitoes, midges, sand flies, and others) and ticks. Other types of arthropods, like chewing feeders, can also be studied.
The course is designed to be a fully self-guided, hands-on experience about setting up an AC-DC EPG monitor, wiring and recording arthropods, measuring waveforms, and statistically analyzing their data; in short, everything you need to do good EPG research.
There is an abundance of readings, handouts, files of example waveforms, analysis programs, and in-depth explanatory lectures on the history, electronic principles, and applications of EPG to modern research. Even for researchers using a DC EPG monitor, the course provides a wealth of in-depth knowledge available nowhere else.
