摘要

摘要本研究旨在建立并验证相豆蓟马(calothrips phaseoli bean thrips)对花生(arachhis hypogaea)危害的图解对数标度。收集人工侵染花生植株的小叶,利用SisCob软件计算受损叶面积(DLA)。编制了6级、7级、8级和9级量表,并利用2-LOG软件获得了每一级的范围。12名评分员使用四种建议的量表对传单进行分析。利用DLA与估算面积之间的线性回归,对量表的精密度和准确度进行了验证;和再现性,通过线性回归之间的估计的评分组合成对。8级标度在准确度和精密度上效果最好,重现性好。

Diagrammatic scale to quantify the damage caused by bean thrips to the peanut crop
Abstract The objective of this work was to develop and validate a diagrammatic logarithmic scale to evaluate the damage caused by the Caliothrips phaseoli bean thrips to peanut (Arachis hypogaea). Leaflets of artificially infected peanut plants were collected, and the damaged leaf area (DLA) was calculated using the SisCob software. Six-, seven-, eight-, and nine-class scales were developed, and the range of each class was obtained with the 2-LOG software. The leaflets were analyzed by 12 raters using the four proposed scales. The scales were validated as to: precision and accuracy, using the linear regression between the DLA and estimated area; and reproducibility, by the linear regression between the estimations of the raters combined in pairs. The eight-class scale shows the best results in terms of accuracy and precision, as well as a high reproducibility.
