Protein profiles of the male accessory reproductive glands of a polyphagous pest, Spodoptera litura (Lepidoptera: Noctuidae) and their glandular secretions were analyzed by electrophoresis under denaturing conditions. The study revealed the presence of 23 proteins in the glands and 14 in the secretions. The molecular weights of the gland proteins ranged from 163 to 3.8 KD whereas that of secretions ranged from 100 to 3.8 KD. The 9 low molecular weight proteins of the secretions are a characteristic feature. It is suggested that the secretions may contain a sex peptide that has a role in the fertility and fecundity of the females.
对多食性害虫斜纹夜蛾（鳞翅目：夜蛾科）雄性附属性腺的蛋白质谱及其腺体分泌物进行了变性条件下的电泳分析。研究发现腺体中有23种蛋白质，分泌物中有14种蛋白质。腺体蛋白质的分子量范围为163至3.8千道尔顿，而分泌物的分子量范围为100至3.8千道尔顿。分泌物中的9种低分子量蛋白质是其特征。有人认为分泌物可能含有一种对雌性生育力和繁殖力有作用的性肽。
