Abstract：The physical method in controlling locust disaster, not only brings the effect of killing locust innocuously, but also conquers the disadvantages of organic toxin remaining in farm produce, locust and entironment brought by chemical controlling. The mechanized pneumatic sucking & capturing locust technique makes the plain locust is controlled innocuously, and promotes the locust resources to be used as feedstuff, and this technique has being developed towards great efficiency in manipulation and extensive range of utilization. According to the Phototaxis of colony locust, the invention patents of optoelectronic inducing & capturing locust technique have been acquired, and this technique combines with the mechanized capturing locust technique gradually, so as to develop towards an integrative optoelectronic & mechanical technique in controlling locust. As a result of the effect of caloric assembling rapidly to death and procreation capability retardarce to biology produced by the high-energy Electromagnetic Wave, including microwave and radiation, the technique of Radiation displays a good effect in controlling the other agricultural pests, and utilized to control locust disaster gradually. Physical method controlling locust, is propitious to entironment protection and the safety of farm produce, as well as realizes the controlling locust innocuously and the locust resource being used, it will become one of the most important techniques in controlling locust disaster in the future.
