摘要
在印度,射孔蛀虫(Euwallacea fornicates)俗称茶螟,在自然条件下侵染茶树枝干的廊道,是茶叶的主要害虫。本次研究的重点是枯草芽孢杆菌在两个不同气候条件的茶叶种植区直接抑制植物病原体生长的拮抗能力。评价结果表明:(a)枯草芽孢杆菌能直接抑制植物病原菌的生长;(b)在离体评价中,枯草芽孢杆菌抑制了伏甲镰刀菌的生长,而伏甲镰刀菌是伏甲的营养物;(c)还发现拮抗微生物和昆虫病原菌能控制茶叶射孔螟的害虫种群数量。在琼脂培养基中,观察了枯草芽孢杆菌对 F. ambrosium 的菌丝生长、孢子和孢子萌发的影响。在田间条件下进行的处理后评估显示,叶面和土壤淋洗平均减少了 40%。因此,我们建议将拮抗细菌枯草芽孢杆菌作为一种 IPM 用于茶叶射孔螟的管理。
Pathogenicity of Bacillus subtilis Against Symbiotic Fungus of Euwallacea fornicates (Coleoptera: Scolytidae) From South India.
In India, the shot-hole borer, Euwallacea fornicates, commonly known as the tea borer, infests the galleries of tea plant twigs under natural conditions and is a major pest of tea. The current investigation focuses on the antagonistic ability of Bacillus subtilis to directly inhibit the growth of plant pathogens in two different climatic regions of tea-growing area. The evaluation reveals that (a) B. subtilis can directly suppress the growth of plant pathogens (b) in the in vitro evaluation; the B. subtilis suppressed the growth of the Fusarium ambrossium, which is the nourishment for the ambrosia beetle, (c) it also revealed that the antagonistic microbes and the entomopathogens are able to control the pest population of the shot hole borer of tea. The impact of B. subtilis on mycelial growth, sporulation, and spore germination of F. ambrosium in agar medium was observed. In the field condition on the post-treatment assessments shows an average decline of 40% in both foliar and soil drenching. Hence, we recommend the antagonistic bacterium B. subtilis for including as an IPM for the management of shot hole borer in tea.
期刊介绍:
The Journal of Basic Microbiology (JBM) publishes primary research papers on both procaryotic and eucaryotic microorganisms, including bacteria, archaea, fungi, algae, protozoans, phages, viruses, viroids and prions.
Papers published deal with:
microbial interactions (pathogenic, mutualistic, environmental),
ecology,
physiology,
genetics and cell biology/development,
new methodologies, i.e., new imaging technologies (e.g. video-fluorescence microscopy, modern TEM applications)
novel molecular biology methods (e.g. PCR-based gene targeting or cassettes for cloning of GFP constructs).
