在英国进行了这样的研究,即在实验室用米象成虫加害小麦,置于20℃和相对湿度70%条件下14周。每周纪录干物质重量损失,为害程度,成虫羽化数和虫粪重量。取样进行组份分析,并确定其氨基酸组成和尿酸含量。结果表明,总干物质损失可达38%。其中原有淀粉含量的损失约43%;原有蛋白质部分的损失为18%。本研究所使用的化学分析方法证实了这一点,用于测定营养成份的标准分析技术也可用来检测由米象为害而造成的小麦的营养变化。
In the UK, a study was conducted in which wheat was weaned on rice in laboratory for 14 weeks at 20 ° C and 70% relative humidity. Weekly record of dry weight loss, degree of harm, number of adult eclosion and weight of insect manure. Sampling for component analysis and determination of its amino acid composition and uric acid content. The results show that the total dry matter loss up to 38%. The original loss of starch content of about 43%; the original part of the protein loss of 18%. The chemical analysis method used in this study confirms this point. The standard analytical techniques used to determine nutrients can also be used to detect the nutritional changes in wheat caused by rice grain damage.
