To test the function of the slippery plate bionic-manufactured based on the surface structure and function of waxy zone in Nepenthes pitchers, attachment force of locust on the slippery plate and the waxy zone was measured by utilizing attachment force measurement system for locust. The experiment of verifying the slippery function of the slippery plate with photoelectric inducing plague locust machine was carried out. The experiments results showed that the attachment force of locust on the slippery trapping plate was 0.94~1.05 times of that on the waxy zone. The slippery trapping ratio was reached to 82.4% when the slanting angle of the slippery plate was 32°. Similarity of the attachment force and considerable slippery trapping ratio probably indicates that the slippery plate bears similar function with the waxy zone, and can satisfy the technical demand of photoelectric inducing and slippery trapping plague locust.
