| 摘 要： | 【目的】以新疆近年来引进种植的优质牧草苏丹草作为诱集植物,探讨不同播种方式对亚洲玉米螟的诱集效应,为玉米螟治理的生态调控技术提供科学依据。【方法】通过在玉米田以不同播种期、不同密度播种苏丹草诱集带和玉米-苏丹草同行混作以及不同品种的玉米田种植苏丹草诱集带等方式对玉米田的亚洲玉米螟发生、为害情况进行比较,明确苏丹草诱集带对玉米螟的生态调控作用。【结果】5月2日、5月27日和6月14日三个不同播种期的苏丹草诱集带对降低玉米田亚洲玉米螟为害率都有显著作用,效果达14.29%~100%;以不同密度播种的苏丹草诱集带和苏丹草—玉米按不同比例同行混作对亚洲玉米螟的诱集效果不显著;玉米螟为害甜玉米美糯2号的程度显著高于普通饲料玉米SC704。【结论】尽管美糯2号甜玉米田的苏丹草诱集带对玉米螟的诱集率较SC704普通饲料玉米田显著高9.4%,但苏丹草的诱集作用对减轻玉米受害程度在玉米品种间并无显著差异。

| Abstract: | 【Objective】Purpose of the paper is to provide scientific evidences for the ecological control Ostrinia furnacalis by trapping crop Sudan grass(Sorghum sudanense) of maize.【Method】The trapping effects of Sudan grass sowed on the single edge of maize field in different sowing date,different density,different varieties,and mixed sowing in maize field were compared to determine the rugulating and control effect on Ostrinia furnacalis.【Result】Results indicated that the traping crop Sudan grass sowed on May 2nd,May 27th and June 14th showed significant positive effect in traping and regulating of Ostrinia furnacalis on maize.Sudan grass with three different sowing periods of May 2,May 27 and Jun.14 had significant effect on decreasing damage from Ostrinca furnacalis in maize field,whose result reached 14.29%-100%.There are no significant effects in trapping Ostrinia furnacalis in the treatments of Sudan grass sowed in different densityies and mixed cropping in maize field.It was observed that damage caused by Ostrinia furnacalis is significant higher on the sweet variety Meinuo No.2 than that of normal forage vareity SC704,and the trapping effect of Sudan grass in the field of sweet variety of Meinuo No.2 is 9.4% more than that of normal forage vareity SC704.【Conclusion】however,the trapping effects of Sudan grass in decreasing the damage between different maize varieties showed no significant differences. |
