蝗虫灾害物理防治发展及应用前景探讨

物理治蝗产生了针对蝗虫生理特性的无毒害化治理效果。负压气流吸入式灭蝗实现了对草原蝗虫无害化治理和蝗虫资源在家禽饲料方面的利用;针对蝗虫的群体性趋光行为,光电诱导捕集蝗虫技术已获取相关的发明专利,并逐步与机械化捕集治蝗技术相结合;微波、射线等辐射技术,利用高能电磁波谱对生物体的聚热致死效应,逐步应用于对蝗灾的防治。物理治蝗有利于生态环境保护和农产品品质安全,必将成为蝗灾治理的重要技术。

Discussion on the Development of Physical Method in Locust Disaster-controlling and its Prospect

The physical method in the control of locust disaster brings the effect of killing locust innocuously.The mechanized pneumatic sucking & capturing locust technique makes the plain locust controlled innocuously,and promotes the locust resources to be used as feedstuff.According to the Phototaxis of colony locust,the invention patents of optoelectronic inducing & capturing locust technique have been acquired,and combined with the mechanized capturing locust technique gradually.As a result of the effect of caloric assembling rapidly to death produced by high-energy electromagnetic wave,the technique of radiation was utilized to control locust disaster gradually.Physical method of the control of locust was propitious to environment protection and the safety of product,and it became one of the most important techniques in locust disaster-controlling in future.
