| 摘要: |
| 灾害蝗虫的光电诱导捕集治理技术是基于蝗虫群体对光源的趋向效应，设置波谱光源与机械机构分别作为灾害蝗虫趋向行为的导向控制因素和诱集蝗虫的收集捕获因素，以此实现致灾蝗虫的有效捕集治理。蝗虫光电诱导趋向行为试验研究证实了短波谱光源的趋光诱导敏感性与趋光增效因素的控制措施，据此研制的光电诱导蝗虫滑移捕集机实现了致灾蝗虫的诱集；仿生研制的滑移捕集滑板能够有效抑制蝗虫附着系统的附着功能并促使诱集蝗虫高效滑移至捕集机的收集装置。灾害蝗虫的光电诱导滑移捕集治理能够抑制喷施化学农药防治导致的生态环境污染问题，还可实现捕获蝗虫的资源化利用，具有良好的应用前景。 |

| Abstract: |
| The technology of photoelectric inducing-trapping locust plague is mainly based on the property of locust phototaxis.It depends on both light source and corresponding mechanical structures which act as the control factor for inducing direction and capturing locust plague.The experimental results confirmed that the light sources with short spectrum obviously inspired high phototaxis, as well as drastically strengthened locust's phototaxis behaviors.Based on locust's phototaxis, the machine of photoelectric inducing-trapping plague locust was designed and manufactured to realize the inducing collection of plague locust.The biomimetic designed slippery trapping plate successfully reduced the attaching ability of locust attachment system and caused the gathered locust to efficiently slide into the machine.Photoelectric inducing-trapping plague locust could avoid ecological environment pollution from utilizing pesticide, and achieve the resource utilization of the captured locust as well.It therefore possesses a comprehensive prospect in the aspect of physical agriculture. |
