Abstract: The sensitive wavelength of pest insects is affected by such factors as pest species, seasonal variation and so on. However, traditional insect trap lamps have fewer band types of emission wavelength, and the lamps are working independently without communication each other, which will cause low effectiveness of insect-trapping and waste of energy. In order to solve the problems of single emission wavelength of insect trap lamp and lamps working independently, an adaptive method of the multi-wavelength of signal light and multi-light coordination methods were developed based on theoretical analysis and the corresponding systematic design, and the maximum expected quantity of insects trapped was calculated. Multi-wavelength of single-light was proposed based on the multi-wavelength and low power consumption of LED. Coordination communication is made between the center trap light and other light traps, which can finally make the wavelength of most lights in the network be the most optimal and the wavelength of a few lights be non-optimal. Using this method, we can not only capture insects efficiently, but also can real-timely detect the change of the pest species in the environment to achieve the optimal catch result. Feasibility and efficiency were confirmed by field trapping test using simulated self-adaption method. So the trap lights can be conveniently used in the wild, and the coordination between multiple lamps can adapt emission wavelength of light traps by themselves to realize the extreme efficiency of the method.
