Experiment on killing and controlling cucumber pests by high voltage static electricity

In order to reduce the pollution of crop and environment caused by pesticides, and seek for physical method to prevent and control pests, based on the principle of killing pests by high static electricity, a kind of pest-killing equipment using high voltage direct current circuit was designed, and an effective deinsectation voltage was identified. Field experiment on killing pests on the cucumber plant leaves was carried out. The experimental results showed that high voltage static electricity method can be used to kill pests and the deinsectation rate for cucumber louse pests was up to 63.6%-70.4%, and 20.99%-26.27% for the other pests. This research can provide a reference for developing equipment for pest prevention and control by using physical method.
