针对性诱剂在吉林省玉米螟田间应用上的问题,发明了一种自动加水性诱剂装置,为性诱剂技术在田间的大范围应用提供理论基础。该文在介绍该装置的外形结构的基础上,在玉米螟的发生盛期,将其与传统的水盆诱捕器进行了比较试验。结果显示,在监测期的比较上,2对装置均呈现极显著的相关关系(P<0.01),消长动态基本吻合。在监测的数量上,传统的水盆诱捕器捕捉得到的玉米螟成虫的数量在0.0263~0.1587,自动加水性诱剂装置捕捉得到的玉米螟成虫的数量在0.0341~0.4441,总体上自动加水性诱剂装置诱集到的玉米螟的数量要高于传统的水盆诱捕器。研究结果表明,自动加水性诱剂装置克服了性诱剂在田间应用上的缺点,并改善了在其应用上的不足之处,具有较高的实际应用价值。
Automatic water-adding of sex lures was invented,aimed to resolve some practical problems of Ostrinia nubilalis in Jilin province.The shape and structure was described in this study.During the peak period of O.nubilalis,the effects of new device and previous method were investigated.The results showed that there was significant relationship for the period monitoring between the two methods(P<0.01).The new device caught more adults of O.nubilalis(0.0341~0.4441)than previous method(0.0263~0.1587).The device overcome the shortcomings of sex lures application in the field,and provided a high value of applications.
