摘要

昆虫肠道微生物关联在营养消化、植物次生代谢物解毒、病原体保护、发育繁殖等方面发挥着重要作用。斜纹夜蛾(鳞翅目:夜蛾科),俗称烟草毛虫,对许多农作物造成严重危害。为了研究肠道细菌的功能作用,研究了斜纹夜蛾幼虫在硫酸链霉素和利福平的饲料中饲养。据观察,抗生素治疗改变了肠道细菌的多样性。肠道可培养细菌数量随着抗生素浓度的增加和饲养时间的延长而减少。硫酸链霉素被观察到比其他抗生素更有效地去除肠道细菌。然而,我们观察到肠道细菌的消除并不影响斜纹夜蛾的生存和发育,这表明细菌可能在斜纹夜蛾的适应度中没有发挥任何显著作用。

Reduction in gut bacterial diversity does not impact on biology of Spodoptera litura (Lepidoptera: Noctuidae)

Insect gut microbial associations play an important role in nutrition and digestion, detoxification of secondary plant metabolites, protection from pathogens, development, reproduction etc. Spodoptera litura (Fabricius) (Lepidoptera: Noctuidae), commonly known as a tobacco caterpillar, causes severe damage to numerous agricultural crops. To investigate the functional role of gut bacteria, S. litura larvae were fed on diet treated with streptomycin sulphate and rifampicin. It was observed that antibiotic treatment altered the gut bacterial diversity. The number of culturable gut bacteria reduced with the increase in concentration of antibiotics as well as feeding duration. Streptomycin sulphate was observed to be more efficient in removal of gut bacteria than the other antibiotic. However, it was observed that elimination of gut bacteria did not affect the survival and development indicating that bacteria may not be playing any significant role in the fitness of S. litura.
