信息素及其在储粮害虫检测中的应用

Pheromones and its application in detection of stored-grain pests

在粮食储藏过程中,准确检测粮堆内害虫种类和密度是害虫综合防治的重要依据,而传统检测方法存在工作量大、检测结果滞后等缺点,因此寻找新的检测手段具有重要意义。研究发现,昆虫信息素具有安全、绿色、微量、高效等特点,可用于储粮害虫的检测与控制。概述了昆虫信息素的结构鉴定、人工合成、采集方法,主要分析了信息素在储粮害虫监测诱捕检测法和信息素成分分析法中的应用研究,并讨论了信息素在上述两种检测方法的应用中所存在的难题,以期为储粮害虫检测技术的发展提供参考。

In the process of grain storage,the accurate detection of pest species and density is the necessary basis in integrated pest management program. However,the traditional detection methods have some disadvantages,such as heavy workload and lagging of detecting results,so it is necessary to find a new detection method. Research shows that,insect pheromone has many characteristics,such as security,green,trace and high efficiency,which can be used to detect and control pests. The structure identification,artificial synthesis and collecting methods of insect pheromone were outlined. The application of pheromone in monitoring trap detection and pheromone components analysis were mainly analyzed. Also,the problems occurred in using the aforementioned detection methods were discussed in order to provide certain references in the development of detection technique.
