| Outline of Final Research Achievements |
Red flour beetle (Tribolium castaneum) and Japanese mealybug (Planococcus kuraunhiae) were controlled by using high electric field. A device for red flour beetle consisted of a center bar and concentric cylinder electrodes, for Japanese mealybug parallel plate electrodes. A high voltage of 5 to 20 kV was applied to the electrodes.
A mortality rate of red flour beetle applied to 500 Hz pulsed voltage of 20 kV for 5 days reached 100 %. Germination and vigor rate of brown rice set under the condition for 4 days was same to control, whereas moisture content decreased by 0.3 % and fat acidity increased by 0.4 % in the vicinity of center bar electrode.
The mortality rate of Japanese mealybug lied under sepal of persimmon placed on a plate electrode at -20 kV DC was 96 % after 4 days voltage application. Weight, color, firmness and Brix value of persimmon fruit did not changed when it was exposed to the electric field for 8 h.
