用性外激素监测害虫发生和消长情况,是近年来发展起来的一种虫情测报新技术。由于它具有灵敏度高,准确性好,使用简便,费用低廉等特点,正在获得越来越广泛的应用。 许多昆虫能向体外释放具有特异性气味的微量化学物质,以引诱同种异性昆虫前去交配。这种在昆虫交配过程中起通讯联络作用的化学物质叫昆虫性外激素或性信息素,用性外激素或其类似物防治害虫时通常叫性引诱剂,或简称性诱剂。目前,性外激素最重要的应用是作害虫发生情况的预测预报。 性外激素测报法以诱捕器作虫情监测工具。诱捕器是由性外激素诱芯和捕虫器两部
With the use of sex hormone monitoring pest occurrence and growth, is developed in recent years, a new technology for insect detection. Because of its high sensitivity, accuracy, ease of use, low cost and other characteristics, is getting more and more widely used.
