To optimize the method of photoelectric inducement trapping used in swarm locust control, influence of photoelectric stimulation with different spectrums was investigated through sliding test of locusts on PVC plastic plate and zinc plate, and rubbing behaviors of locusts on these plates were observed by means of CCD video monitoring system. Both distinctive slippery ratio and considerable sliding behaviors are exhibited when the peak wavelength of photoelectric stimulation is 460 nm without consideration of slippery plates. Presumably, photoelectric stimulation with such peak wavelength can inspire bio-photoelectric effect of locust much more strongly, and enhance moving activity of locust more effectively, which of it can cause obvious reduction of contact area between locust and slippery plate. Photoelectric stimulation with the spectrum of 460 nm presumably can disturb the forming of mechanical interlock and decrease the adhesive force more obviously. Therefore, friction effect is weakened evidently and much more obvious sliding behaviors are presented. The result supplies a suitable theoretical foundation for the design of photoelectric stimulation sources used in slippery trapping plates to control swarm locusts and other agriculture pests.
