A significant decrease in essential amino acids of wheat, maize and sorghum was observed due to grain infestation caused by mixed populations of Trogoderma granarium Everts and Rhizopertha dominica Fabricius (50:50). Non-essential amino acids were also adversely affected. Among the essential amino acids, maximum reduction was found in methionine, isoleucine and lysine in infested wheat, maize and sorghum grains, respectively. Lysine, with lowest chemical score in uninfested and infested grains of three cereals, is the first limiting amino acid. Insect infestation caused significant (p < 0.05) reduction in the chemical score of all the essential amino acids, yet did not change the position of first and second limiting amino acids in wheat and sorghum. However, in case of maize, isoleucine became the second limiting amino acid. Infested grains also showed substantial reduction in essential amino acid index, calculated biological value and requirement index.
由于谷斑皮蠹（Trogoderma granarium Everts）和谷蠹（Rhizopertha dominica Fabricius）混合种群（50:50）造成的谷物侵害，观察到小麦、玉米和高粱中的必需氨基酸显著减少。非必需氨基酸也受到不利影响。在必需氨基酸中，受侵害的小麦、玉米和高粱籽粒中蛋氨酸、异亮氨酸和赖氨酸的减少量分别最大。在三种谷物未受侵害和受侵害的籽粒中，赖氨酸的化学评分最低，是第一限制氨基酸。昆虫侵害导致所有必需氨基酸的化学评分显著降低（p < 0.05），但并未改变小麦和高粱中第一和第二限制氨基酸的位置。然而，在玉米中，异亮氨酸成为第二限制氨基酸。受侵害的籽粒在必需氨基酸指数、计算生物学价值和需求指数方面也显著降低。
