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 asthe 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 be35毅~40毅.
