分别以储藏期为1年和9年的散存稻谷为试验粮食,并对粮虫陷阱检测器和扦样选筛法应用效果进行评估。结果表明,粮虫陷阱检测器检测工作效率明显高于扦样选筛法,两种方法分析害虫群落物种组成、测定粮堆低密度和高密度害虫分布效果相似。说明粮虫陷阱检测器检测效果稳定,重复性、相关性和可比性强,是一种理想的储粮害虫检测技术。
The experiment was conducted on the paddy rice with 1-year and 9-year storage period, respectively, and the application effects of the trap-insensitive trap and the screen-dressing method were evaluated. The results showed that the detection efficiency of the worm trap detector was significantly higher than that of the sampling and sieving method. The two methods were used to analyze the species composition of the pest community, and the distribution of the low-density and high-density insect pests was similar. It indicates that the detection effect of grain worm trap detector is stable, repeatability, correlation and comparability, which is an ideal storage grain pest detection technology.
