概括
该研究发现,Beauveria bassiana有效控制大麻虫 (Phorodon大麻),而不会损害植物质量. 这种生物控制支持大麻素和烯的生产,与化学杀虫剂不同.
科学领域:
- 农业昆虫学 农业昆虫学
- 植物病理学 植物病理学
- 生物技术是生物技术.
背景情况:
- 加拿大大麻行业的合法化后扩张导致了更多的害虫问题,特别是大麻虫 (Phorodon cannabis).
- 害虫感染对大麻sativa作物的健康和产量构成重大威胁.
- 现有的害虫防治策略可能会对大麻的生化特征产生负面影响.
研究的目的:
- 为了调查Phorodon大麻对Cannabis sativa的影响.
- 评估昆虫病原菌的有效性,特别是Beauveria bassiana和Metarhizium anisopliae,作为对P.cannabis的生物控制剂.
- 评估生物与化学害虫防治对大麻sativa的大麻素和烯资料的影响.
主要方法:
- 从受感染的虫中分离和描述Beauveria bassiana和Metarhizium anisopliae.
- 在体外感染试验以确定各种度的P.cannabis的真菌疗效.
- 温室试验比较B. bassiana,化学杀虫剂和未经处理的对照在三种Cannabis sativa品种.
- 对虫种群动态的分析和治疗和未治疗植物中关键大麻素和烯的量化.
主要成果:
- 贝奥维利亚巴西安纳和Metarxizium anisopliae都在1x10^7 conidia/mL时实现了100%的虫死亡率,而B. bassiana显示出更高的疗效.
- 温室试验表明,B. bassiana在9周内保持了接近零的虫种群,与化学杀虫剂治疗相当.
- 与B. bassiana治疗的Cannabis sativa显示出较高的大麻素 (THCA,CBDA) 和总烯度,与受过杀虫剂治疗的植物相比,在一些品种中,未经处理的植物.
- 杀虫剂治疗显著降低了大麻素和烯水平.
结论:
- 贝沃里亚巴西安纳是一种高效和环保的生物控制剂,用于控制大麻虫 (Phorodon cannabis).
- 与化学杀虫剂不同,B. bassiana的处理可以保护和潜在地提高大麻sativa的生物化学质量 (大麻素,烯).
- 这项研究支持采用B. bassiana用于大麻行业的可持续害虫管理,确保作物健康和产品质量.

Microbe-Plant Interactions
140
Microbe-plant interactions represent a dynamic spectrum of associations shaped by intricate chemical signaling. These interactions can be neutral, beneficial, or detrimental, and profoundly influence plant physiology, growth, and ecosystem function. The plant microbiome, comprising bacteria, fungi, archaea, protists, and viruses, plays a pivotal role in mediating these effects through surface colonization, internal colonization, or systemic symbiosis.Mutualistic associations, particularly with...

Production of Biopesticides
108
Biopesticides offer a sustainable alternative to chemical pesticides, utilizing microbial agents to control agricultural pests. Bacillus thuringiensis (Bt) is a widely employed bacterium known for its potent insecticidal activity. Bt biopesticides are favored for their specificity to insect pests, minimal environmental impact, and natural degradability.Mechanism of Bt Toxin Action Bt produces insecticidal crystal (Cry) proteins during its sporulation phase. These proteins form parasporal...
