High Voltage Electric Fields Have Potential to Create New Physical Pest Control Systems

open access: yesInsects, 2020
An electric field is the space surrounding an electric charge, within which it is capable of exerting a perceptible force on another electric charge. Especially under high voltage, electric fields induce various electrostatic phenomena, some of which ...

Electric fields and electrical insulation [PDF]

open access: yesIEEE Transactions on Dielectrics and Electrical Insulation, 2002
The adoption of a field-theoretical approach to problems arising in the framework of electrical insulation is discussed with reference to six main topics, which have been addressed over the last 30 years. These include uniform field electrodes, Green's differential equation, electrode surface roughness, induced charge, electrostatic probes, and partial

Target-Size-Dependent Application of Electrostatic Techniques for Pest Management in Greenhouses

open access: yesAgronomy, 2022
Two new electrostatic devices were developed to manage greenhouse insect pests. One was an electrostatic insect catcher (EIC) to trap small flying pests, and the other was an arc-discharge zapper (ADZ) to kill larger insects emerging from soil beds.
