摘要
为明确黑龙江省齐齐哈尔地区不同秸秆还田方式下玉米田双斑萤叶甲(Monolepta hieroglyphica)发生动态,采用黄色粘虫板进行诱集监测,同时调查田间诱集的主要天敌昆虫.2021、2022年试验结果表明,玉米秸秆翻埋还田、秸秆碎混还田、秸秆覆盖还田、秸秆移出对照4种方式下双斑萤叶甲诱集高峰期和全诱集期诱虫量有差异,秸秆碎混还田方式诱虫量最多,显著高于秸秆翻埋还田和秸秆移出对照,与秸秆覆盖还田差异多为不显著.黄板主要诱集天敌为异色瓢虫(Harmonia axyridis),玉米秸秆翻埋还田、秸秆碎混还田、秸秆覆盖还田、秸秆移出对照4种方式瓢虫诱虫量差异不显著.
Abstract
To clarify the occurrence dynamics of Monolepta hieroglyphica in maize fields under different straw returning methods in Qiqihar of Heilongjiang Province,we used yellow sticky traps to monitor the pest and also the main natural enemy insects.The experiments performed in 2021 and 2022 showed that there were differences in the trapping peak and total catches of the four treatments:corn straw burying and returning to the field,straw crushing-and-mixing returning to the field,straw covering and returning to the field,and straw removal.The number of trapped insects was the highest in the straw crushing-and-mixing returning treatment,which was significantly higher than that of straw burying and returning and straw removal control.However,there was no significant difference between crushing-and-mixing returning and straw cover returning treatment.The yellow sticky traps mainly caught Harmonia axyridis,and there were no significant differences in the amount of H.axyridis trapped among the four straw returning treatments.
