亚洲玉米螟性信息素鉴定及其应用研究进展

Research progress on sex pheromone identification and application of Asian corn borer

【目的】综述近年来国内外关于亚洲玉米螟性信息素鉴定、综合防控及应用的研究进展,为亚洲玉米螟的监测预警、绿色防控等技术提供参考依据。【方法】运用文献统计学方法收集资料及调研,分析国内外亚洲玉米螟性信息素防治技术研究与应用的进展。【结果】亚洲玉米螟在中国、韩国、日本、菲律宾等国家均有分布,雌性个体通过释放性信息素吸引雄性继而交配;鉴定亚洲玉米螟主要性信息素组分为顺/反-12-十四碳烯醇乙酸酯(Z/E-12-14:Ac)和正十四碳醇乙酸酯(14:Ac),各组分作用不同,组分间比例存在地理种群差异;亚洲玉米螟性信息素产品已运用于监测、诱杀与交配干扰中,与其它防治技术相结合的集成技术防效显著;应用过程中存在多种影响性信息素诱剂诱捕效率的因素,包括性信息素剂量、诱捕器类型、放置高度、颜色及环境等。【结论】亚洲玉米螟在多个国家的玉米种植区均有分布,亚洲玉米螟性信息素比例存在地理种群差异,利用性信息素最佳组分系统结合影响性诱剂诱捕效率的多种因素,在田间防控亚洲玉米螟取得了较好效果,我国已组装、集成一套基于性信息素防控亚洲玉米螟绿色防治技术。

【Objective】Reviewing the domestic and foreign research progress on sex pheromone identification,comprehensive prevention and control and application of Asian corn borer in recent years,in order to provide an important reference for the monitoring,early warning and green prevention and control of Asian corn borer in my country.【Methods】Statistical methods were used to collect literature data,and the progress of domestic and foreign literature on the research and application of sex pheromone control technology of Asian corn borer was analyzed.【Results】The Asian corn borer is distributed in China,South Korea,Japan,the Philippines,etc.Females release sex pheromones to attract males and then mate;The main sex pheromone components of the Asian corn borer were identified at home and abroad as cis/trans-12 tetradecanol acetate(Z/E-12-14:Ac)and n-tetradecyl acetate(14:Ac).The effects of each component were different,and there were geographical population differences in the proportion of components;At present,the sex pheromone products of the Asian corn borer have been widely used in monitoring,mass trapping and mating interference,and the integrated technology combined with other control technologies also has significant control effects;There are many factors affecting the trapping efficiency of sex pheromone lures during the application process,including sex pheromone dosage,trap type,placement height,color and environment,etc.【Conclusion】The Asian corn borer is distributed in the corn planting areas of many countries.There are geographical population differences in the proportion of sex pheromone of the Asian corn borer.The best component system of sex pheromone,combined with various factors affecting the trapping efficiency of sex pheromones,has achieved good results in field prevention and control of the Asian corn borer.China has assembled and integrated a set of green control technology based on sex pheromone to prevent and control the Asian corn borer.
