基于二点螟性诱剂次要组分的诱蛾活性研究

摘要

目前,甘蔗田间应用的二点螟性诱剂成分为顺-11-十六碳烯醇(Z11-16:OH),有研究表明与甘蔗二点螟同种异名的粟灰螟雌蛾腺体提取物中除含有Z11-16:OH外,还含有5%~10%的十六醇(16:OH).为探明十六醇作为性诱剂次要组分时能否进一步改善诱蛾效果,本文进行了多点多代的甘蔗二点螟田间诱蛾试验,结果表明,16:OH含量在5%~10%范围内对甘蔗二点螟的诱蛾活性没有明显提高也没有抑制作用.%The sex attractants ofChilo infuscatellus Snellen which is used in farmlands at present is (Z)-11-Hexadecenol. Some studies have reported that the extractive of gonad of the female moth contained 1-Hexadecanol which ranged from 5% to 10% besides (Z)-11-Hexadecenol. To find out the effect of 1-hexadecanol when it is as one of the components of sex attractants ofChilo infuscatellus Snellen, we did trapping tests in farmlands, and the results showed that it had no effect on improving trapping effect when the content of 1-Hexadecanol ranged from 5% to 10%.
