WebThe electrical penetration graph or EPG is a system used by biologists to study the interaction of insects such as aphids, thrips, and leafhoppers with plants. Therefore, it can also be used to study the basis of plant virus transmission, host plant selection by insects and the way in which insects can find and feed from the phloem of the plant. WebIn addition, we used high-magnification video observations to correlate EPG waveforms with the insect's posture, head movements, and muscle contractions. Also, EPGs were correlated with probing on liquid diets containing radio-active tracers to distinguish and quantify ingestion waveforms.
