Gut bacteria, which serve as essential modulators, exert a significant impact on insect physiology and behavior and have substantial application potential in pest management. The dynamics of gut bacteria and their impact on Phortica okadai behavior remain unclear.
In this study, the dynamics of gut bacteria at different developmental stages in P. okadai were analyzed using 16S ribosomal RNA (rRNA) gene sequencing, and the species and abundance of gut bacteria that affect host behavior were examined via behavioral experiments.
A total of 19 phyla, 29 classes, 74 orders, 101 species, and 169 genera were identified. The results of the behavioral experiments indicated that the species Lactiplantibacillus argentoratensis, Acetobacter tropicalis, Leuconostoc citreum, and Levilactobacillus brevis effectively influenced the feeding preference of P. okadai, and the single-bacterium-seeded P. okadai exhibited feeding preferences distinct from those of the germ-free (GF) and wild-type P. okadai.
The species and relative abundance of gut bacteria together positively impact P. okadai behavior. Lactiplantibacillus argentoratensis, as the most attractive bacteria to P. okadai, presents opportunities for novel pest control strategies targeting this vector and agricultural pest.
肠道细菌作为重要的调节剂,对昆虫的生理和行为有重大影响,在害虫管理中有很大的应用潜力。肠道细菌的动态及其对大稻蝗行为的影响尚不清楚。
本研究采用 16S 核糖体 RNA(rRNA)基因测序分析了大稻蝗不同发育阶段肠道细菌的动态变化,通过行为实验研究了影响宿主行为的肠道细菌的种类和丰度。
共鉴定出 19 个门、29 个纲、74 个目、101 个种和 169 个属。行为实验结果表明,Lactiplantibacillus argentoratensis、Acetobacter tropicalis、Leuconostoc citreum 和 Levilactobacillus brevis 等物种有效影响了大稻蝗的取食偏好,单种细菌接种的大稻蝗表现出与无菌(GF)和野生型大稻蝗不同的取食偏好。
肠道细菌的种类和相对丰度共同影响大稻蝗的行为。Lactiplantibacillus argentoratensis 是对大稻蝗最具吸引力的细菌,为针对这种媒介和农业害虫的新型害虫控制策略提供了机会。
