高压脉冲电场对黄粉虫幼虫杀灭效果研究
The Effect of High Voltage Pulsed Electric Field on Killing Larvae of Flour Beetle
摘要
Abstract
In this study,the larva of flour beetle as the object has been used in research,and it been shocked by the high voltage pulsed discharge equipment to get data of lethal rate, the experiments in air were carried out. Different combinations of needle and plate electrodes used in the test and used varying electrode spacing in the in-sulating chamber. The voltage scale of high frequency electric pulse set to 5 kV,10 kV,20 kV and 50 kV respec-tively. Different discharge times were also set to get the lethal rate of flour beetle under different environment of e-lectric fields. The test results showed that the higher voltage and lower electrode gap would increase electric field strength that improved lethal rate;the needle-plane electrode had the best killing effect in this test;and the lethal rate was stable and the growth is not obvious after 15 s operation time.关键词
