摘　　要：为给灾害蝗虫光电诱导滑移捕集装置中滑板材料的优选与滑板倾角的设定提供技术支持,设计了蝗虫附着力测试系统（精度为1 mN,量程为0-3 N）,并利用该系统进行了蝗虫在不同材料和不同倾角捕集滑板上的附着力测试。结果表明,当分别以镀锌铁板、PVC板和普通玻璃板为滑板时,蝗虫的附着力均随着倾角的增加而减小;对于确定倾角的滑板,蝗虫在镀锌铁板上具有较小的附着力,故镀锌铁板较适宜作光电诱导滑移捕集装置的滑板,相应的最小倾角为35°-40°。In order to provide technological reference for selecting materials and setting slanting angle of slippery trapping plates in plague locust capturing machine,attachment force testing system（the resolution is 1mN,the measurement range is 0~3N） was designed,and attachment force of locust on the plates with different materials and slanting angles were measured with this system.The experiment results exhibited that with the different materials of the plates,like zinc plate,PVC plate and silicate glass plate,the attachment force of locusts decreased apparently as the slanting angle increased.For the fixed slanting angle,the attachment force of locusts on zinc plate showed the much lower values.Based on the experiment results,zinc plate was more suitable for the plate and the minimum slanting angle should be 35°~40°.
