Technical Abstract: Until recently, most Electrical Penetration Graph (EPG) studies have emphasized small-bodied sternorrhynchans, auchenorrhynchans, and thrips. EPG holds the potential to significantly improve research on a wider array of species, such as large heteropterans and blood-sucking vectors of medical/veterinary pathogens. The key to broadening applicability of EPG is to update the electronics and increase flexibility of instrument settings. A recently designed 3rd-Generation, Universal AC-DC EPG monitor provides either AC or DC applied signal, plus more modern, high-quality amplifiers with a wider range of user-selectable sensitivities (input impedances) compared to previous monitor designs. A waveform library is a series of EPG recordings showing variation in the appearance of a waveform when recorded at different input impedances. Shifts in appearance reveal electrical origins (R vs. emf) of each waveform type. Representative waveform libraries are shown for several representative psyllid and heteropteran species. These insects range in size from 1–18 mm in length, constituting a wider array of insect sizes than has been recorded in the past.
